I am trying to figure out how I can determine during runtime whether my app is running natively on the M1 processor or is using Rosetta translation. I have a universal app that works well, but seems to be defaulting to Rosetta even though I have not checked the “Run using Rosetta” option.

Like this: If TargetMacOS Then If SystemInformationMBS.isARM Then MsgBox "Running ARM version on ARM CPU." Elseif SystemInformationMBS.IsTranslated Then MsgBox "Running Intel version on ARM CPU." Else MsgBox "Running Intel version on Intel CPU." End If End If

This doesn’t need to be in the Testers channel.
