I use Parallels mainly for Quickbooks and a couple of other PC only apps. Sometimes I need to do this on my Mac at work and sometimes on my 2nd Mac at home. Ideally, I'd like to just transfer the whole VM between Macs so that the whole Windows install is mirrored but is that going to cause Activation problems when I launch Windows on the 2nd Mac? I have 2 copies of Windows but that won't help as Windows will see it as me running 1 copy on 2 Macs if it's tied to hardware. Am I going to have to just copy any files I want to work on and keep 2 separate Windows installations? Anybody got a good workflow for this, I'm sure it's a common problem?
