Re: MacOS support; agenda item ESC

Hello,
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)
https://bugs.documentfoundation.org/show_bug.cgi?id=85499
https://bugs.documentfoundation.org/show_bug.cgi?id=108801

Inertial scrolling switches to zoom if you start pressing a new shortcut key (cmd) -> Simple fix to 
change it to ctrl?
https://bugs.documentfoundation.org/show_bug.cgi?id=46429

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
https://bugs.documentfoundation.org/show_bug.cgi?id=31915
https://bugs.documentfoundation.org/show_bug.cgi?id=98842

3D slide transitions are broken
https://bugs.documentfoundation.org/show_bug.cgi?id=57128
https://bugs.documentfoundation.org/show_bug.cgi?id=115497

A few CJK or similar issues
https://bugs.documentfoundation.org/show_bug.cgi?id=108042 (not able to show e.g., cmd in toolbar 
shortcuts) - major
https://bugs.documentfoundation.org/show_bug.cgi?id=123555 (not able to show chinese text in index, 
probably related to above) - major
https://bugs.documentfoundation.org/show_bug.cgi?id=114272 (some font fallback not working, see my 
latest comment) - not sure of severity
https://bugs.documentfoundation.org/show_bug.cgi?id=129620 (CRASH in editing header in Calc) - not 
sure if major
https://bugs.documentfoundation.org/show_bug.cgi?id=128537 (CRASH when pressing cmd+^2) - minor
https://bugs.documentfoundation.org/show_bug.cgi?id=82115 (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:
https://github.com/neooffice/NeoOffice
https://trinity.neooffice.org/modules.php?name=Forums&file=viewforum&f=8 (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
