Hi Rosa,
Do you know if anyone else has had success getting eyelink working with the apple silicon chip, either with or without Rosetta 2?
Yes, Yoon Bai in the DiCarlo Lab is using it successfully with MWorks 0.11.
As I noted in that discussion, any EyeLink error is likely to crash MWServer. The issue in MWorks 0.12 guarantees an error opening the EyeLink data file, but an unrelated error will do it, too. If you send me your latest crash log, I can see exactly where things are failing and suggest possible fixes.
Thanks,
Chris
