Zwift

iMac 2012, Core i5, 16gb RAM, GeForce GT 755M 1gb graphics, 1TB Samsung SSD.

Updated to Sonoma as soon as it was available from the OpenCore team but it was choppy as hell and kept crashing Zwift after exactly 17 minutes and 53 seconds. Put it down to ‘early adoption’ and rolled back to Ventura. Zwift ran absolutely sweet on Ventura again. Tried to update OpenCore to version 1.3.0 and it completely trashed my install of Ventura. Had to start again so I decided to take a punt on Sonoma once again since it’s had its first update. Zwift continues to crash at 17 minutes and 53 seconds. It doesn’t freeze, or bug out, it just closes and there is no record on Strava or Zwift that I ever rode for those 17 minutes at all.

Does anyone have any ideas why this would happen on Sonoma only? I don’t really want to spend Christmas Eve fresh installing Ventura again. Or worse - building a Windows PC!!!!
