fixed : Mac’s internal storage nearly full due to iOS Files

Question :
My Mac is slow, and I can’t install updates anymore… I found out, by looking in Settings > General > Storage, that I only have about 5 GB of free space… and after the waiting for the internal storage volume bar to color up and indicate which types of files take up most space, I found out (by clicking on it) that the Applications have two sections : not only Applications (which are the installed macOS Applications I presume), but also something called “iOS Files” which take up about 45 GB…

What are those iOS Files ? and can I delete them to free up memory space ?

Answer :
Yes, it can be a good idea to free up some free space on the internal memory of your Mac by deleting those iOS Files. They are in fact backups of your iPhone(s), which you don’t need on your Mac if your iPhone is being backed up to iCloud.
Basically there are 2 ways of deleting these iOS Files from your Mac, one is deleting them without connecting your iPhone to your Mac, the other is a way that requires your to connect your iPhone. But if you have so little free space left (only a few GBs) you will need to combine the two to solve your problem :

  • first, make sure your iPhone is being backed up to iCloud, so open your iPhone
  • then, open the Settings.app
  • in the Settings window that opens, click on your Account ( your Own Name )
  • in the Account window that opens, click on iCloud
  • in the iCloud window, go to the “Saved to iCloud” chapter and click on “See All”
  • in the Saved to iCloud window, make sure taht everything that you want to include in your backups turned ON
  • then, go back into the iCloud window, go to the “iCloud Backup” chapter and click on it
  • in the iCloud Backup window that opens, make sure that “Back Up This iPhone” is switched ON
  • then, click “Back Up Now”
  • when the backup is finished, go to your Mac
  • on your Mac, open the Finder.app
  • when the Finder window is open, press the [CMD]+{SHIFT]+[G] key combo on your keyboard
  • in the search window that opens, in the search field, typ the following :
  • ~/Library/Application Support/MobileSync/Backup
  • then press Enter
  • in the Finder window that opens you will see a folder named Backup
  • drag&drop that Backup folder onto your Trash
  • then, empty the Trash
  • when warned that some files can’t be deleted, just continue
  • when the emptying has finished, open the Trash and drag the Backup folder back into the location that it used to be in ( which is in the MobileSync folder inside the Application Support folder )
  • now your Mac should have a lot more memory space freed up, but you’re not finished yet
  • now, connect your iPhone to your Mac using a USB or USB-C cable
  • on your Mac allow “trust this computer’, and unlock your iPhone by using your unlock passcode or face-recognition
  • NOTE : if you get a warning that a software update is needed for your Mac to recognise your iPhone, install that update first
  • now, your iPhone will appear in the sidebar of the Finder
  • when your iPhone shows up, click on it
  • in the iPhone’s settings window that opens, click on the General tab
  • then, in the General tab, in the Backups chapter, choose “Backup your most important data on your iPhone to iCloud”
  • then, go on to the Options chapter, make sure that only “Manually manage music, movies and TV shows” is checked and click the Apply button
  • then, exit the iPhone in the Finder and unplug the iPhone’s cable from your Mac
  • now, open the Finder.app again and press the [CMD]+{SHIFT]+[G]
  • in the search filed that opens, again, typ the following :
  • ~/Library/Application Support/MobileSync/Backup
  • and press Enter
  • now, in the window that opens, click on the Backup folder
  • when the Backup folder opens, drag&drop all it’s contents ( usually only one folder with an unpronounceable name ) to the Trash
  • then empty the Trash
  • and close the Finder.app
  • That’s it !

fixed : delete multiple old mails at once in Mail.app on iPhone or iPad

Question :
On my Mac, in the Mail.app, I’ve always been fond of the option to select multiple eMails (mostly junk-mail) and delete them at once… but on my iPhone I have to delete each mail one-by-one (swipe left, click More, scroll down, click Delete Message) …that’s no problem if it’s only 5 eMails, but when it’s 10 or 20 eMails that I want to delete, it takes a lot of time and a lot of swiping…
Now a friend adviced me to sart using the Gmail.app to do this… and Gmail.app has this as a standard feature, and Mail.app doesn’t (as far as I know) …but I love using Mail.app and prefer to keep using Apple’s own stuff…

Isn’t there any way to do this in Mail.app ?


Answer :
YES, there is !
Okay – it’s slightly more complicated than in the Gmail.app for some unknown reason… but the option is there – to use it, do this :

in iOS / on iPhone :
– open Mail.app
– if you’re not already in the mailbox that you want to delete the eMails from, open the proper mailbox in the Mailboxes list window
– in the window where all eMails are listed, click Edit (top-right)
– now all eMails will slide slightly to the right and at the left, a round checkbox will apear in front of each eMail
– then, check all eMails that you want to delete (or move)
– when all are selected, click Move (bottom-centre)
– from the popup, select Move Message
– then, on the next screen click on Bin (or Trash) to delete all selected eMails
– the screen will automatically close and go back to the previous screen (your selected mailbox)

in iPadOS / on iPad :
– open Mail.app
– make sure you are in the right mailbox, if not, click the menu icon (top-left) and select the desired mailbox from the list that appears on the left, and click on the menu icon (top-left) again to close the list of mailboxes that had appeared on the left
– in the window of your desired mailbox, the list of eMails will be visible on the left and the preview of the selected eMail will be in the middle and right
– then click on Edit (top-right-in-the-left-column), above the list of eMails
– now all eMails will slide slightly to the right and at the left of them, a round checkbox will appear in front of each eMail
– then, check all eMails that you want to delete (or move)
– when all are selected, click Move (bottom-centre-in the left-column)
– from the popup, select Move Message
– then, in the list that appears on the left, click on Bin (or Trash) to delete all selected eMails
– the slide-in menu will automatically close and you will be back in the regular screen of the active mailbox

Note : both on iPhone and iPad, you can also use this method to move multiple eMails to the junk-mailbox or archive them to any desired mailbox

That’s it !

fixed : how to remove a legacy system extension from your Mac

Question :
I got a warning from macOS that there is a legacy system extension om my Mac that will not be compatible with the next version of macOS.
Is there any way to remove this extension from my Mac ?

Answer :
If you know which extension is causing this problem, you can remove it.

The main problem is that the warning message will probably not mention the name of the system extension itself, but only the name of the developer. In that case you will need to look up the name of the developer on the Internet and see which system extension that you have installed is/was made by this developer. Once you know the name of the app and the associated system extension, you can remove that particular system extension.

If you can’t figure out which system extension is causing the warning, DO NOT remove any extension !! DO NOT proceed to the next steps if you are not completely sure about the exact system extension you need to remove, because removing the wrong system extension will cause serious problems !!

If you are completely sure, and only if you are entirely sure, about the exact System Extension that is causing this problem, you can remove it by doing this :
– click somewhere on the Desktop to open the Finder
– make sure that “Finder” is visible next to the Apple-icon in the far left of the top menu bar
– select “Go” from the top menu bar
– in the pulldown menu that appears, click on “Go to Folder…”
– in the search field of popup window that appears, type the following text :
/Library/Extensions/
– then hit the [Enter]-key on your keyboard
– in the window that opens, the “Extensions” folder will be highlighted and its content will be visible
– select the .kext-file that has the name of the System Extension you are looking for and drag it to the Trash
– in the popup window that appears, type the password that unlocks your Mac and click “OK”
– then empty the Trash
– and close all Finder windows

That’s it !

fixed : Delete needless empty page that is created at end of Pages document

Question :

I am creating a one-page document in Apple Pages with a complex layout and all is well until I drag my text boxes too close to the edges of the page… then a new blank page (with header and footer) is created that I can’t delete…

I’ve tried the things that used to work in previous versions of Pages (and work in MS Word), like selecting the page in the thumbnails, but than I get a warning saying “Are you sure you want to delete all content from your document?” and if I click Delete assuming that that will only delete the blank page, it will delete the entire layout-ed page and only leave the blank page (so… exactly the opposite of what I intended) …and if I try the other ‘proven solution’ of setting the cursor on the blank page an then deleting all invisible content on that page by repeatedly pressing the Backspace and/or the Delete key… nothing happens…

What is wrong and how can I fix this ?

Answer :

In the newer versions of Apple Pages (like Pages version 13) you need to choose if your document is going to be a Text Editor document (e.g. an old-style Word document) or a Layout document (e.g. a PowerPoint/Keynote-style document with layout and text boxes). If you want to make your Pages document a Layout document, you have to change that manually, as a new Pages document is set to be a Text Editor document by default. To fix that, do this :

  • have your document open in Pages
  • click on the ‘Document’ button (top right in the icon bar of the document window, next to ‘Format’)
  • in the side panel that opens on the right select the ‘Document’ tab (next to ‘Section’ and “Bookmarks’)
  • go to the bottom of the ‘Page Orientation’ chapter (just above the ‘Document Margins’ chapter)
  • there, make sure the checkbox at ‘Document Body’ is empty (by clicking on the checkmark if there is any)
  • then click ‘Convert’ in the popup screen
  • then select the unwanted blank last page in the thumbnails on the left and press the ‘Delete’ or ‘Backspace’ key on your keyboard… and the troublesome blank last page will disappear…

…that’s it !

fixed : Red Pin (in My Places) seems undeleteable in Apple Maps

Question :

I have an old location that I had once looked up in Apple Maps which was marked with a Red Pin. Now I no longer need it, so I want to delete it. Normally I would do that by clicking on the Red Pin in Apple Maps.app on my Mac, so the More Info window would open with a Delete-button… but for this particular Red Pin there is no Delete button… (even though the Delete button appears if I do this same thing with any other Red Pin…)

It’s even worse… this Red Pin is in a My Places ‘folder’ also, and even though I get the option to delete it there, it will automatically reappear in the same My Places ‘folder’ instantly after being deleted…

I’ve searched the internet multiple times, but no-one seems to know how do fix this… a lot of people seem to have run into this or a similar problem, but the solutions given just don’t work for me…

Is there any fix for this ?


Answer :

There is a fix (but no guarantee it will work for all similar problems). Try this :

  • first, close Apple Maps.app on your Mac
  • then, open Apple Maps.app on your iPhone
  • swipe the Search field (or actually the pull-up screen) upward to fill the screen with the More Info window
  • now, find the Red Pin you want to delete : it may be in the Recents chapter, or in the Favourites chapter, or you may have to dig a little bit further to find older Red Pins
  • once found, slide the info line of the Red Pin from right to left ; now a red Delete button will appear from the right ; click it to delete the Red Pin

If you also want to delete the Red Pin from the My Places ‘folder’, try this :

  • in Apple Maps.app on your iPhone, swipe the search field upward to fill the screen with the More Info window
  • scroll down to the My Guides chapter and click on the My Places ‘folder’
  • you will now see the map, with the pull-up screen now named My Places (or any custom name you have once given to the ‘folder’)
  • if you don’t see the Red Pin you want to delete, swipe up the pull-up screen and scroll down until you see the Red Pin you’re looking for
  • then, slide the info line of the Red Pin from right to left ; now the red Delete button will appear from the right ; click it to delete the Red Pin
  • then, click the X-marked button top right to go back to the main view (back to the More Info window)

And if you want to delete the My Places ‘folder’ (or any of the My Guides ‘folders’) entirely, try this :

  • in Apple Maps.app on your iPhone, swipe the search field upward to fill the screen with the More Info window
  • scroll down to the My Guides chapter and find the ‘folder’ you want to delete (e.g. the My Places ‘folder’)
  • then, slide the info line of the folder you want to delete from right to left ; now the red Delete button will appear from the right ; click it to delete the ‘folder’

That’s it !

…to check if this has worked, open Apple Maps.app on your Mac and your ‘undeleteable’ Red Pin will now be gone… (if this solution works in your case too)

fixed : delete an old TimeMachine-backup file from a Time Capsule

Question :

I’ve bought a new MacBook and I want to use my existing Time Capsule for it’s TimeMachine-backups, but it’s full. The backup-file, a .sparsebundle-file, from my previous MacBook that I am going to pass on to one of my children, is far too big.

I have installed my new MacBook from the old MacBook’s TimeMachine-backup, so I am not needing that backup again, but I want to make two new TimeMachine-backups as soon as possible : one for my new MacBook and one for the old MacBook right after my child starts using it.

But, I can’t seem to delete the old .sparsebundle-file from my Time Capsule completely… I’ve done several attempts, but I keep running into the same error message “The operation can’t be completed because some items had to be skipped. For each item, choose File > get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again.”. On first sight, the .sparsebundle-file is still there. On further inspection, it turns out the the .sparsebundle-file has shrunken in size.

But… what can I do to completely delete the old .sparsebundle-file ?

 

Answer :

This problem can occur especially with bigger and older .sparsebundle-TimeMachine-backup-files. Note that the really new TimeMachine-backup-files have a .backupbundle-extension, not a .sparsebundle-extension, but there is hardly any difference

To be able to delete the old .sparsebundle-file, start by doing this :

  1. connect your new MacBook to the Time Capsule using a UTP/Ethernet-cable
    • make sure to shut off AirPort/WiFi on your MacBook :
      • in the top menu-bar, click on the AirPort/WiFi-icon (the piece of pie)
      • in the pulldown-menu, set the WiFi-slider to OFF
    • if you do not have an Ethernet-port or a USB-to-Ethernet-converter on your MacBook :
      • connect your MacBook to the Time Capsule using AirPort/WiFi
      • but make sure to disconnect all other AirPort/WiFi-connected devices
  2. Make sure that your Time Capsule has the latest firmware installed :
    • goto Applications > Utilities > AirPort Utility
    • open AirPort Utility
    • in the AirPortUtility-window, click on your Time Capsule’s picture
    • when prompted, enter the Time Capsule’s password
    • in the popup-window, at ‘version’ check if there is an update available
    • if so, click on the button to install it
    • if just the version number is shown, you already have the latest firmware installed, so you don’t need to do anything extra here
    • exit AirPort Utility
  3. Make sure that you have read&write-privileges on the .sparsbundle-file you want to remove :
    • right-click ( CTRL-click ) on the Finder-icon (blue-grey face icon) in the far left of the Dock
    • from the popup-list, select New Finder Window
    • scroll down to the “Locations” group in the menu list at the left and click on “Network”
    • in the window that opens, goto Network > Time Capsule
      • if you have multiple Time Capsule devices, make sure you select the Time Capsule that the .sparsebundle-file you want to delete is actually on
    • if it says “Not Connected” click the “Connect as”-button and typ the Time Capsule’s password
    • if it says “Connected”, you’re good
    • open the Data folder and right-click ( CTRL-click ) on the TimeMachine-backup-file you want to delete
    • from the popup-menu, choose Get Info
    • in the Get Info window that opens, choose these settings :
      • uncheck the check-box at “Locked” (so the file is unlocked, i.e. delete-able)
      • uncheck the check-box at “Hide extension” (so the .sparsebundle extension will be visible in the file name)
      • at “Sharing & Permissions” set Privilege for “everyone” to “Read & Write”
    • close the Get Info window

Having set the above, there are various options that might enable you to delete the old .sparsebundle-file (or .backupbundle-file). Your options are listed below, from simple to extreme. Read all of them before starting, and choose the option you want to try first. Any of these might be successful, and if the one you chose first doesn’t work, just try another one.

Option #1 : delete the .sparsebundle-file from within the Finder

  • goto Finder > New Finder Window
  • goto Locations > Network > Network > Time Capsule > Data
  • right-click ( CTRL-click ) on the .sparsebundle-file you want to delete
  • from the popup-list, select “Move to Bin”
  • wait for the “Move to Bin” action to complete
  • if it doesn’t end in an error, empty the bin/trash (and you’re done)
  • if this ends in an error, try any of the other options

Option #2a : additional TC reset

  • restart your Time Capsule by unplugging the power cable for 30 seconds
  • plug the power cable back into the Time Capsule
  • when the Time Capsule comes back online, follow the directions from Option #1

Option #2b : additional Mac reset

  • shut down your Time Capsule by unplugging the power cable (for 30 seconds)
  • shut down your MacBook by selecting Shut Down from the Apple-menu top-left
  • plug the power cable back into the Time Capsule
  • restart your MacBook by pressing the power button
  • when both your Time Capsule and your MacBook have restarted, follow the directions from Option #1

Option #2c : additionally disconnect other devices

  • shut down your Time Capsule by unplugging the power cable (for 30 seconds)
  • now, disconnect all UTP/Ethernet-cables leading to other devices than your MacBook (you can even disconnect the cable connected to your internet modem-router)
  • shut down your MacBook by selecting Shut Down from the Apple-menu top-left
  • plug the power cable back into the Time Capsule
  • restart your MacBook by pressing the power button
  • when both your Time Capsule and you MacBook have restarted, goto Applications > Utilities > AirPort Utility
  • in the AirPort Utility window, click on the picture of your Time Capsule, typ your password if needed and check which devices are connected
  • then, one-by-one go to each device listed and shut down it’s WiFi-connection
  • when done, close the AirPort Utility application and reopen it
  • again, in the AirPort Utility window, click on the picture of your Time Capsule, typ your password if needed and check which devices are connected
  • you should now see no devices listed at “wireless clients” (except for your MacBook if you aren’t able to connect it using a UTP/Ethernet-cable)
  • then, follow the directions from Option #1
  • NOTE : do not forget to plug all UTP/Ethernet-cables back into your Time Capsule and switch on WiFi on all devices that were previously connected

Option #3 : by backing up the Time Capsule content

  • NOTE : you will need a Mac-connectable external USB-harddisk for this ! (at least as many GBs as the internal HD of your Time Capsule, so 500G, 1TB, 2TB, 3TB of larger)
    • to check if the USB-harddisk is Mac-connectable, plug it into your Mac and if it pops up you’re okay
    • if it doesn’t show up, it’s a Windows NTFS-disk that needs to be reformatted to Mac Journailed format ( note that this erases all content, so ONLY reformat it if it’s an empty brand-new external harddisk ! )
  • NOTE : this method will work 99% of the time, but it will probably take (far) more time than any other method
  • start by connecting the external USB-harddisk to your Time Capsule’s USB-port
  • then, on your MacBook, goto Finder > New Finder Window
  • then, in the top menu-bar, goto Finder > Preferences
  • in the Finder Preferences window, click the Sidebar tab
  • in the list that shows up, make sure that “External disks” and “Connected servers” are checked
  • then close the Finder Preferences window
  • now select the New Finder Window you had just opened
  • goto Locations > Network > Network > Time Capsule
  • next to the Data-folder, there is now a new folder named after your externe USB-harddisk
    • for the following, assume that your extern USB-harddisk folder is simply called “usb-HD”
  • goto Locations > Network > Network > Time Capsule > usb-HD
    • if the “usb-HD” folder is completely empty, you’re okay
    • else, click on the “More” icon (the circle with 3 dot in it) and in the dropdown menu click “New Folder” and call it “TC-backup”
  • goto Locations > Network > Network > Time Capsule > Data
  • inside the Data-folder select all files (both backup-files and other files) that you DO NOT want to delete
  • drag&drop all the files into Locations > Network > Network > Time Capsule > usb-HD
    • it may take some time for all files to copy over, so let it run
    • if you run into an error, try copying over every file one-by-one
    • if you still run into an error, just try again
  • when all files are copied over, you can unplug the external USB-harddisk from your Time Capsule
    • as an extra safety precaution, you can unplug the power cable from your Time Capsule before you unplug the USB-cable and replug the power cable when the external USB-harddisk is disconnected
  • then goto Applications > Utilities > AirPort Utility
  • open AirPort Utility
  • in the AirPortUtility-window, click on your Time Capsule’s picture
  • when prompted, enter the Time Capsule’s password
  • in the popup-window, click the Edit-button
  • in the window that opens, select the “Disks”-tab
  • in the Disks window, click the “Erase Disk”-button
  • next, choose the level of security for the erase (“Quick Erase” should do fine, since you are going to use the disk for the same purpose immediately afterwards)
  • then click “Update” and the Time Capsule’s status light wil flash orange-yellow until the disk is erased and the Time Capsule is accessible again
  • then, exit AirPort Utility
  • goto Locations > Network > Network > Time Capsule > usb-HD or Locations > Network > Network > Time Capsule > usb-HD > TC-backup (depending on where you put your Time Capsule back-up files)
    • if you don’t see the “usb-HD” folder, make sure your external USB-harddisk is plugged back into your Time Capsule
  • now, select all files from the back-up folder (either “usb-HD” or the “TC-backup” folder within it)
  • drag&drop all the files into Locations > Network > Network > Time Capsule > Data
    • it may take some time for all files to copy over, so let it run
    • if you run into an error, try copying over every file one-by-one
    • if you still run into an error, just try again
  • when the copying is finished, you should now have your Time Capsule the way you wanted it : exactly the same (backup) files on it’s disk, but without the .sparsebundle(s) you don’t need anymore

Option #4 : manually deleting all files inside

  • goto Finder > New Finder Window
  • goto Locations > Network > Network > Time Capsule > Data
  • right-click ( CTRL-click ) on the .sparsebundle-file you want to delete
  • from the popup-list, select “Open Package Content”
  • in the Finder window that opens click on the “bands” folder
    • if the “bands” folder appears empty, just wait a few moments for its content to appear in the Finder window
  • SHIFT-click on the top file and scroll down to select multiple files, then press the Backspace-button on your keyboard to delete them
    • you are able to select and delete up to 8000 files per batch (according to user ‘cmaryg’)
    • if a batch refuses to delete at the first attempt, just try again – usually it will eventually be deleted anyway (according to user ‘cmaryg’)
    • if a batch refuses to delete after a few attempts, reduce the number of files in it by selecting less files at once and try deleting again
    • if you happen to run into a single file that refuses to delete, do this :
      • right-click ( CTRL-click ) on the file
      • from the popup-list, select “Get Info”
      • in the window that opens, make sure that there is no checkmark at “Locked”
      • then try deleting the file again
  • then repeat this for the next batch of files, until the “bands” folder is completely empty
  • if the “bands” file is completely empty, close the Finder window that displays the “bands” folder
  • then, goto Finder > New Finder Window
  • goto Locations > Network > Network > Time Capsule > Data
  • right-click ( CTRL-click ) on the .sparsebundle-file you want to delete
  • from the popup-list, select “Move to Bin”
  • if it doesn’t end in an error, empty the bin/trash (and you’re done)
  • if this ends in an error, you can still try Option #3, but probably this will help too :
    • goto Locations > Network > Network > Time Capsule > Data
    • right-click ( CTRL-click ) on the .sparsebundle-file you want to delete
    • from the popup-list, select “Open Package Content”
    • in the Finder window that opens, select the top folder and drag it to the bin (trash)
    • repeat this for all folders listed
    • then, select the top file and drag it to the bin (trash)
    • repeat this for all files
    • if you run into a file that refuses to delete, do this :
      • right-click ( CTRL-click ) on the file
      • from the popup-list, select “Get Info”
      • in the window that opens, make sure that there is no checkmark at “Locked”
      • then try deleting the file again

That should be it !

As mentioned before : the Option #3 method will work (nearly) always, but it’s time-consuming and you will need a lot of extra disk space for it (on an external harddisk).

fixed : how to backup incompatible iOS apps ?

Question :

I have iOS12 running on my iPhone and I found that some the apps I have installed are no longer able to run on iOS12. I would like to delete these apps to save space on my iPhone, but I also want to make sure I have backup versions of all of them, because I might want to reinstall them in the future and Apple doesn’t guarantee that you will always be able to re-download all previous purchases (Apple will delete them from the AppStore when Apple judges the apps obsolete or inappropriate due to new regulations, even if I have payed to purchase them in the past).

How can I backup my incompatible apps ?

 

Answer :

Technically, one would be able to backup all iPhone/iPad apps to iCloud wirelessly, or to iTunes on your Mac (or PC), but then you risk the app being deleted by Apple at any moment in the future, without warning and without compensation.

So, I would recommend using additional backup-/filetransfer-software on your Mac (or PC) to do so…at this moment iMazing 2 is a good option, but there are various alternatives around.

You can get iMazing 2 here. (the trial version is FREE)

And there currently is a discount version of iMazing 2 available here.

Here’s how to backup incompatible iOS apps :

  • on your iPhone/iPad go to Settings > General > About > Applications > Incompatible apps
  • make screen dumps (by pressing menu button & NO/OFF-button simultaneously) of the list of incompatible apps ; make multiple screen dumps if the list is very long
  • connect the iPhone/iPad to your Mac using a USB-cable
  • start the iMazing 2 app on your Mac (or use similar software)
  • click on your iPhone/iPad’s icon in the list on the left
  • from the pulldown list, select Apps
  • in the overview of installed iOS apps that shows up in the main screen, select the app that was listed first in the list of incompatible apps
  • then click the “Copy to Mac”-button
  • you will get a warning, telling you to make a full backup of your device ; do that first
  • when that’s finished, make sure that the first incompatible app is selected, then click “Copy to Mac” again
  • when asked where to save, select your desired save location and create a new folder and call it “incompatible apps iOS12” or something alike
  • then click OK 
  • when done, select the second incompatible app and click “Copy to Mac”
  • save to the same “incompatible apps iOS12” folder
  • when asked, choose “Extract from current backup”
  • then repeat the saving process for all incompatible apps
  • when done, check if all incompatible apps you need are in the “incompatible apps iOS12” folder
  • if you missed one, back it up also
  • when done, select the first incompatible app again and click “Delete”
  • repeat that for all incompatible apps
  • in doing so, you will free up lots of valuable drive space on your iPhone/iPad

That’s it !

enjoy 😉
