[GAP Forum] Need help from users of Magma on Mac OSX

[Dima Pasechnik]

Hi Gordon,

I don't have Magma, but we are struggling with porting SageMath to macOS 11.
That is, if something untested on macOS 11 doesn't quite work there (despite Apple PR department 
assuring you thaty it should), it's not suprise at all.
That is, if your Magma predates macOS 11.2, it's not a surprise, but something for Magma people
to fix (either you, or Simons - they say,prompted by the biggest Magma customer ;-) - 
paid for the license, I suppose :-)).

HTH
