I hope to get an M1 in the near future as my 2014 iMac is getting slower and slower.... I have Parallels (with Windows 10 on it,) as well as a much newer MacBook Pro (which I can use if there are problems with the M1 and Parallels and Windows. From what I understand, Parallels now in production in the past day or so will now work with the M1. My question is with Windows. I understand I have to get a copy of the test version of their Windows ARM OS. I assume that this means that my existing PVM files are useless and that I will have to re-install my several programs that I use Windows for from scratch. I have a new Startech Serial-USB converter that I use for one of the programs. What are my chances that will work? Any other gotchas I should be aware of ? Thanks.
