I'm new to both Apple and Parallels so this might seem like a simple question but I've received different answers. I'm currently using a 2011 Mac Air with factory installed Lion OS (4GB & 128GB), Parallels 6 with Windows 7 (64), external Iomega portable hard drive with 2 partitions (1 exclusively for Time Machine & 1 for Carbon Copy Cloner where every week I clone the entire Mac Disk including Parallels partition). I purchased all three last month and everything is working to my delight for what I'm using it for. I have just received a Build 12106 update for Parallels 6 and also another email telling me I can now get the free upgrade offer to Parallels 7. I know how Windows Restore works but don't know about Mac regarding this so here are my questions for these scenarios to see if I can better understand the process: Scenario 1- I update to the new Build 12106 for Parallels 6 and it doesn't work as it was before Scenario 2- I upgrade to Parallels 7 and it doesn't work like Parallels 6 is working for me. I say this because I've been reading this forum and there are so many issues with 7 that I'm afraid to switch from Parallels 6 which is working fine for my needs although I'd like a few of the new things it does (like remote with the iPhone or iPad) plus it's a free upgrade and the current version. In Windows I could just Restore and it would revert to the way it all was before and delete any new programs I had installed. Can I just open Time Machine and restore to how I had it yesterday without the update or do I have to uninstall everything and start all over again maybe from the Cloned drive that had all the previous versions installed that were working correctly?
