I am running Mac OS X Lion 10.7.5 on an older Mac Book Pro. Once my Parallels license expired I attempted to renew and was told to upgrade to Parallels 12, but it seems not to be compatible with my Mac operating system running a 10.7.5. Since my Mac Book is older I am not sure that I can upgrade the operating system. I got the error message that it will not run on anything less than OS X 10.10.10.
I wrote and asked an earlier version, Parallels 10 and received a key for that, but I then received a message "unable to perform the operation" license server rejects it.
I am an Accountant and I have previous tax returns I cannot get access to because i can open up Parallels. So does anyone have any ideas.
