Will time machine backup my whole Adobe CS apps? I wish to upgrade my OSX and am worried I lose my Adobe CS apps since they were issued by my (ex)college and i do not have the keys/seriel#'s

I didnt quite understand the answer given. Will a TM backup save all this apps/data so if my new osx gives me problems I can 'go back' and recover the previous osx and ALL my apps/data incl the Adobe stuff! ?

thanks D
First of all you should not use applications you don't have licenses for.

Yes, time machine backs up all data. If you chose to reinstall the same OS X version on the same computer everything should be the same.

Please keep in mind, though, that adobe's creative suite (CS1) does not work on newer versions of OA X/macOS.
