openslide on Apple silicon?

[Jon Sauer]

Hi Benjamin,

Yes indeed, my whole environment on the new Mac Studio was migrated from my old 15” 2016 MacBook Pro, an x86_64 machine just as you surmised.

Many, many thanks. I’ll make the necessay changes, only mention something again if I can’t make it work.

Thanks again.

Cheers,
  Jon
