Using Delphi 12 and OSX SONOMA does not work, it is seen fuzzy.
While using Delphi 11.3 then you see it correctly.
Another thing I noticed, if you put the cell in editing , the cell is seen correctly.
Tested with both firepower X2 and X3
I'm attaching a photo.

  I did some tests here are the results:
  Delphi 11.3 - OSX BIG SUR = Work.
  Delphi 11.3 - OSX SONOMA = Work.
  Delphi 12 - OSX BIG SUR = Work.
  Delphi 12 - OSX SONOMA = not Work.

  Thank you for your tests. It is very helpful to us.

  I have just researched this issue today and it seems like a bug in Delphi 12 with the method Scene.GetSceneScale. It should return the scale used in your Mac environment, but it seems to always return 1. This causes the fonts to be fuzzy.  We will log a bug in the Delphi reporting system, but not sure when they will fix this.

  A temporary workaround seems to be to set GlobalUsesMetal in your project. Then GetSceneScale returns the correct value.

   

  begin
    GlobalUseMetal:= true;
    Application.Initialize;
    Application.CreateForm(TFPDataModule, FPDataModule);
    Application.CreateForm(TMainDemoForm, MainDemoForm);
    Application.Run;
  end.

  Yes with this set you can see correctly.

  The problem is that you can't use it with GlobalUseMetal, because on databases with 50000-100000 records associated with the wwdatagrid component the program goes into out memory

  What is your PaintOptions.PaintEfficiency set to? Can you tell me if you still get the globalusemetal exception error if it is set to BufferRecords?

  Also are you running on an arm computer or an intel? Also I tried a table of over 400,000 records and was not able to reproduce your problem. Any chance you can email us a simple project with the problem so we can figure out why the error is occurring?

  PaintOptions.PaintEfficiency -> BufferRecords
  
  It's on an M1 apple chip.
  It does this by both compiling in OSX64 and ARM64
  Okay, I'll do some tests and let you know.
  In the meantime, thank you.

  I've done some testing, and I think it's an out memory problem using GlobalUseMetal has nothing to do with wwdatagrid.
  Also inserting GlobalUseSkia works, but the performance on TBitmap is very bad, very slow.
  The problem is very frustrating.

  Can you try the following test build. I think it may solve your issue.
