fixed : macOS Sierra downloaded but installer won’t run

Question :

Since the latest version of OSX (entitled “macOS Sierra) has been yesterday, I wanted to install it on my Mac. I clicked on “download” in the Mac AppStore and  the download started ; on the dedicated product page I could see the status bar filling up and finally stating “downloaded”… but then, nothing happened…

The download wouldn’t install…

I re-checked if macOS Sierra does support my Mac, it does. So I tried restarting the AppStore-app, I tried logging out my iCloud/AppStore-account & than logging back in, I tried rebooting my Mac, I tried rebooting in SafeMode, I tried FirstAid in the Disk Utility app, I tried clicking 10 times on the “downloaded” button repeatedly, I tried installing the DeBug-menus & cleaning the AppStore cache, I tried deleting the hidden AppStore downloads folder… and I tried various command line solutions found online in the Terminal app… nothing helped… I am still stuck with the button under the macOS Sierra icon saying “downloaded”… and nothing happens…

What can I do ?

 

Answer :

You are probably not (really) going to like this answer, because this will set you back hours & hours, in which you can’t use your Mac ; but it’s the only way known to solve this, and you need to have a recent TimeMachine backup (or alike) for it :

  1. shut down your Mac
  2. disconnect all cables  from your Mac (except your keyboard & mouse if you haven’t got a MacBook)
  3. restart your Mac, and be quick to press the [CMD]+[R] key-combo during startup (your Mac will now start up in Recovery Mode)
  4. in the “OS X Utilities” window that appears, select Restore From TimeMachine Backup and click Continue
  5. in the next “Restore Your System” window, click Continue
  6. now first make sure that your Mac can connect to your TimeMachine-harddisk by plugging in it’s USB-cable, plugging in your Ethernet-network-cable or connect to your WiFi router
  7. then select the hard drive that has your TimeMachine backups on it and click Continue
  8. in the next window, make sure you select the most recent backup that is from before you tried to download macOS Sierra ; only if you’re sure you’ve selected the right backup, proceed and click Continue
  9. now wait (or do something more useful in the mean time) and wait and wait ; this is going to take hours and hours ; putting back a TimeMachine backup this way will go a a speed of about 30BG per hour, so if your hard drive is 500GB it may take you about 15 hours (yes, an entire night and an entire morning…)
  10. finally, once the TimeMachine backup-reinstall is done, your Mac will restart… just let it
  11. then, when logged in, open the Mac AppStore-app and notice that the button under the macOS Sierra now says “download” ; click on it
  12. after the download has completed, you should now see the installer window popup on your screen… proceed from there…

that’s it… it’s simple, but very time-consuming…

fixed : can’t delete unnamed app without icon from iPad

Question :

I have an icon on my iPad that has a generic icon and no name. If I double click it, the name turns into “Waiting…” and nothing happens, even after a long wait. If I try to delete it, I get the small X-tag, and if I click on it, I get a window saying :

Delete ‘  ‘

Deleting ‘  ‘ will also delete all of its data.

…and two options to click on : “Delete” and “Cancel”

…still no name of the app is given, and since the icon is generic (a.k.a. “empty” ; showing only a greyish-white icon with a dark grey grid, some circles and diagonals) I still don’t know how to delete it.

What can I do to fix this ?

 

Answer :

For some reason (unknown and probably irrelevant also) this app has stalled during an update or even during it’s initial install. To figure out the actual name of the app, do this :

  • in iOS, go to “Settings” –> “General” –> “Restrictions”, and make sure you have permission to delete apps and change accounts
  • then, go to “Settings” –> iTunes and App Store and log out
  • then, when in iOS8, go to “Settings” –> “General” –> “Usage” –> “iCloud” –> “Manage Storage” ; in the next window, click on “Backups” ; in the next window, click on “Show all apps”
  • or when in iOS9, go to “Settings” –> “General” –> “Storage & iCloud Usage” –> “STORAGE” –> “Manage Storage”
  • now find the app that has a generic icon in the list of apps you see
  • write down the name of that app (the one with the generic icon)
  • then, when the Menu-button has a white square icon on it, restart your iPad (or iPhone) by simultaneously pressing the Menu-button (below the screen) and the ON/OFF-button (on the right top edge of your iPad’s/iPhone’s housing, hold this key-combo until your iPad/iPhone shows a white Apple-logo on a black screen, then release
  • or, when the Menu-button has fingerscan, restart your iPad (or iPhone) in the way described in this post
  • when the reset is done, login to your iPad (or iPhone) if you have an access pincode on it
  • then, go to “Settings” –> iTunes and App Store and login
  • then, when in iOS8, go to “Settings” –> “General” –> “Usage” –> “iCloud” –> “Manage Storage” ; in the next window, click on “Backups” ; in the next window, click on “Show all apps”
  • or when in iOS9, go to “Settings” –> “General” –> “Storage & iCloud Usage” –> “STORAGE” –> “Manage Storage”
  • now find the app has still with the name that you wrote down (this app may or may not have a generic icon now) and click on it
  • in the next window click “Delete App”
  • then click the Menu-button to get back to the main screen
  • then go to the “App Store”-app –> “Purchased” –> “Not on this iPad” (“Not on this iPhone”)
  • in the list, find the app with the name you wrote down and (re)download it from the App Store by clicking on the ‘cloud with blue downward arrow’-icon behind its name
  • when the app starts downloading, click on the Menu-button to return to the main screen
  • finally, turn restrictions back on if you had any initially (in “Settings” –> “General” –> “Restrictions”)

…that’s it – enjoy !
