Parallels generally meets my expectations. I’m running a Mac Mini M1 (ARM processor) with Mac OS Monterey and Windows 11 (Insiders Beta). Windows is installed on an external NVME drive. The only real problem that I have experienced is that I cannot get windows to properly recognize serial data through a USB 2 connection (i.e., a serial GPS receiver). Mac OS sees it just fine, Windows will not. I sure hope that this issue is resolved with future updates of Parallels and/or Windows.
