fixed : Legacy System Extension warning for MATTINGALLS extension

Posted on by

Question :

Ever since I upgraded to macOS 13 Ventura, after each reboot, I get a warning saying “Legacy System Extension – Existing software on your system loaded a system extension signed by “MATT INGALLS”, which will be incompatible with a future version of macOS. Contact the developer for support.”

What is this about ? And what can or should I do about it ?


Answer :

The reason you get this warning is because you have installed the SoundFlower extension on your Mac. SoundFlower is a FREE system extension that lets you route sound from one application to another. That can be useful to record audio from your Mac, among others…

But… development on SoundFlower seems to have stalled… the latest developer who took over the SoundFlower-project from RogueAmoeba was Matt Ingalls (so that’s where te warning comes from…) but he hasn’t released any new versions recently…

The last version that was released only runs on Intel-Macs (so not on M1 and M2-Macs) and will not be compatible with macOS 14 Sonoma and beyond…

Note : clicking ont the “More info” button in the warning window will lead you to this info on Apple’s website, but it will not give any useful info on SoundFlower

If you want to follow up on Apple’s advice to ‘contact the developer’, you can contact Matt Ingalls here to request a new release of SoundFlower or if you are looking for the latest info on the SoundFlower-project, look here : https://github.com/mattingalls/Soundflower/releases

If you want to remove the Soundflower-extension that is causing this warning, do this :
[ a big thanks you to celticparrotj for posing this question ]
– 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 “Soundflower.kext” file 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

If you are looking for an ALTERNATIVE to replace the SoundFlower extension, give BlackHole a try : https://github.com/ExistentialAudio/BlackHole

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 !

enjoy 😉

fixed : CanoScan 5600F driver for macOS Ventura

Question :

I have a Canon CanoScan 5600F scanner that worked great with my previous Mac, but now I have upgraded to a new M1 Mac running macOS 13 Ventura.

I’ve looked on the Canon website and searched the internet, but there is no macOS 13 Ventura compatible driver available for this scanner.

Is there any way to use this CanoScan 5600F scanner in macOS 13 Ventura ?

Answer :

Yes, there is …and it is reported to work on M1 (and M2) Macs also [ thanks ! @Stefan ] :

  • goto Canon’s US website : https://www.usa.canon.com
  • choose Support > Scanners > Film & Negative Scanner > CanoScan 5600F
  • or use this link : https://www.usa.canon.com/internet/portal/us/home/support/details/scanners/film-negative-scanner/canoscan-5600f/canoscan-5600f?subtab=downloads-drivers
  • there, choose the “Drivers & Downloads” tab
  • then, choose “macOS Mojave v10.14” (even though your on macOS Ventura v13 – don’t worry) as your operating system and “English” as your language
  • then, choose the “Drivers” tab
  • now, you will see 2 drivers listed :
    • > 5600F Scanner Driver Ver.14.11.5h (Mac) : msd_-mac_cs5600f-14_11_5h-ea8_2.dmg
      • > ICA Driver Ver.4.1.4a (Mac) : misd-mac-ijscanner2-4_1_4-ea21_3.dmg
  • download both of them
    • note that despite the fact that both are versions from 2018, these will still work with macOS 11.0 Big_Sur
  • goto your downloads folder
  • first, double-click on the file named msd_-mac_cs5600f-14_11_5h-ea8_2.dmg
  • this will mount the ScanGear_CanoScan 5600F_141105.pkg
  • again, click on that and version 14.11 of the ScanGear driver installer will open
  • now, follow the on-screen directions and the latest ScanGear driver will be installed
  • then, double-click on the file named misd-mac-ijscanner2-4_1_4-ea21_3.dmg
  • this will mount the Canon IJScanner2_040104.pkg
  • again, click on that and version 4.1.4 the IJScanner2 driver installer will open
  • now, follow the on-screen directions and the latest IJScanner2 driver will be installed
  • when done, goto System Preferences > Printers & Scanners
  • if the CanoScan 5600F is already listed on the left, click it
  • if not, click the +sign (plus-sign) to add the scanner first
  • when done, click the CanoScan 5600F in the list on the left
  • when the scanner details open on the right, click on the “Open Scanner”-button
  • now, the built-in macOS scanner-app will open and it will immediately do a preview scan of whatever is in the scanner

NOTE : you might run into a small problem every once in a while ; when the automatic scanning preview starts, you might get an error saying “Scanner reported an error – Cannot communicate with scanner for these reasons: – Scanner is turned off. – USB cable is disconnected. Please check and try again.” If so, just flip the scanner’s ON/OFF-switch in OFF-position manually and then back into ON-posistie. That should help in making the scanner preview work again.
