How to update Windows 7 and Parallels Desktop 9 before updating to El Capitan I'm using a Mac for about 3 years now and updating OS X has never been an issue because it's free, but since I installed Parallels Desktop v9 and Windows 7 I'm reading issues about their compatibility on OS X 10.11 El Capitan where they are both not supported.

So upon coming to this issue I would rather ask an expert to tell me how to do it right and which should I upgrade first without damaging any of my files? Please kindly assist me step-by-step on how to do it properly.
You should probably keep your apps up to date before installing an OS that you know will be incompatible with their older versions.


Take a Time Machine backup of everything.
Update Parallels through this link. You'll get it for $49.99 (as opposed to $79.99) because you're upgrading from a relatively recent version.
Open the new Parallels and play around with your files to make sure everything works.
Once you're satisfied that the new version of Parallels works, take a new Time Machine backup.
Install El Capitan.


Good luck!
