The team at Symplast would like to provide some background information on why we are forcing our M1 based users to enable the Rosetta setting. Many of or M1 based Mac users have reported a variety of App crashes after upgrading to Monterey. Most, if not all, of the reported crashes have been the result of a bug in the Apple Operating System (Monterey) in how the M1 processor handles certain instructions.

After upgrading to Monterey, the M1 processor handles certain instructions differently than before. This has caused issues for many Apps, including Symplast Practice App after upgrading from Big Sur to Monterey. This is currently a known issue for Apple and they are working on a solution. However, the intermediate solution is to enable the Rosetta setting as described.
