MacOS support; agenda item ESC

here’s some input from me after having tested quite a few macOS bugs through the years:

The download page needs to show some of the different known issues. E.g., today it should show a warning on Catalina that you may need to grant LO "Full Disk Access” if running on a standard account or installing a language pack - otherwise save as and open is broken. People should not have to google this issue, as most will give up before then.

The most major issue is to get code signing to work on the regular app bundle, and then at some point the SDK 10.15 causing blurry text need to be resolved.
It would probably help to update to modern macOS frameworks, not sure if Skia would help here

I read through the list of open macOS bugs (there’s only 220!) and here are some notable major ones and CJK issues

Text is blurred if having a Retina screen and low-dpi external screen (NeoOffice has actually fixed this recently)

Inertial scrolling switches to zoom if you start pressing a new shortcut key (cmd) -> Simple fix to change it to ctrl?

Modal dialogs aren’t properly modal. Likely cause issues such as being able to quit in the save dialog (e.g., if you press cmd+q twice too fast by accident) and other problems

3D slide transitions are broken

A few CJK or similar issues (not able to show e.g., cmd in toolbar shortcuts) - major (not able to show chinese text in index, probably related to above) - major (some font fallback not working, see my latest comment) - not sure of severity (CRASH in editing header in Calc) - not sure if major (CRASH when pressing cmd+^2) - minor (CRASH when changing font in comment of partly written text) - probably minor

Also, what is the relation to NeoOffice?
They publish their sources and have e.g., fixed the bug with mixed Retina and low-dpi screens: (bug fix announcements)

They have also implemented many native macOS functionalities, e.g., Dark mode, and seem to have a better quicklook and mdimporter plugin?

They have this on their FAQ page: 
Why is NeoOffice separate from OpenOffice and LibreOffice?

The primary reason that we stay separate is that we believe that we have produced a product that is more stable and more secure on Mac than either OpenOffice or LibreOffice.

Developing and maintaining the NeoOffice code requires a massive amount of our time. Since neither OpenOffice nor LibreOffice have ever offered to fund our work, working within the OpenOffice or LibreOffice projects is not a feasible option for us.

AFAICT from the sources, they’re on LO 4.4 which in other ways is quite suboptimal
