This will work fine, I've been doing the same since the M4 Mini launched (but using UTM instead of Parallels ... I'll save my Parallels licenses for things that actually benefit from them)But after reading more about this , I think I’m going to just not get the 2012
Use a VM on the m4 like parallels (I’ve used this before) or something else.
Run the VPN+torrents in the VM, that shouldn’t interfere with plex
I hope
