* Integration tools like copy/paste between VM and host, or file sharing, didn't work
* Graphics constantly glitched, often going to a grey screen. There seemed no way to recover, and I had to force restart the VM
The drivers / assistant tools have a 2012 date on them.
I'm aware it's a free product and I have no right to expect anything (and I don't; I went back to Fusion.) And perhaps the situation would improve if I or others financially supported the project, which seems a better response to issues :) Nevertheless I went in hoping I could replace the commercial VM solutions, which on Mac have required yearly updates that deliver almost no new value, with something open source -- and I can't yet.
