>> "1. The debugger Native OS Exceptions options for the non-Windows platforms do not have a "privileged instruction" setting, so the question arises: Are there settings with different names that need to be configured differently than they are out of the box? "
Not that we know of. Delphi added that option to the Windows version somewhere down the line. So, it wouldn't surprise us if in a future version they'll add it to the macOS version of their product.
>> "2. Also, wrapping the LimeLM Mac *.dylibs and Linux *.so's will require updates to the sample TurboActivateUnit.pas file. It won't work as-is on anything but Windows targets."
The updated example Delphi example included in TA 4.1 and newer (out soon) will include a version of TurboActivateUnit.pas that works for macOS and Windows.
