32-bit

The main reason why sticking to macOS 10.13 High Sierra all the way into September 2021 was the preference to stay with some applications:

  • MS Office 2011 – absolutely “good enough” and still had very nice feature of reopening all open docs/windows of application (Word, Excel, PowerPoint) was restated (or suddenly died), feature that WAS REMOVED (!!) from Office 2016/Office 365.
  • Adobe CS5 suite (including e.g. Photoshop, Dreamweaver, and many more apps) – with perpetual license (no annoying subscription, which is only choice for many Adobe apps nowadays)

 

More – not (yet) here…

… but on local desktop and Dropbox file share

Trickier subjects…

  • /mlabs/audio/
  • Keyboards! (Lots off-line, only, for the time being)

Most materials so far are not in this CMS.

System Extensions

About system extensions and macOS – support.apple.com/en-us/HT210999

Some system extensions aren’t compatible with current versions of macOS or won’t be compatible with a future version of macOS. Learn what to do if you see an alert about system extensions or kernel extensions.

System extensions work in the background to extend the functionality of your Mac. Some apps install kernel extensions, or kexts—a kind of system extension that works using older methods that aren’t as secure or reliable as modern alternatives. Your Mac identifies these as legacy system extensions.

In 2019, Apple informed developers that macOS Catalina will be the last macOS to fully support legacy system extensions, and we’ve been working with developers to transition their software.
