This is a question for the experts:
I would like to do a clean install, but I have some programs that were a "1 time install only" i.e.: Word for Mac that I was able to obtain for cheap while in school. If I install a clean version of Yosemite, is there a way to transfer a program back? Possibly from a TM backup? And lastly, I see most posters state to install from a thumb drive, can anyone give an EASY step by step tutorial on how to do this? At this time I feel comfortable restoring all my other programs except for Word, and I would really like to save my self some $ by not having to buy it again. Thanks!
