I know windows machines and the tools to clean them up / delete temp files / update apps, etc. A friend wants me to help him with his 5 - 6 year old Mac. I know I can go into about this mac, check for updates (or similar), go to flash site, acrobat, shockwave, etc to update each of those.
Is there a better way to do that? Are there temp files or other things to delete? What are the leading utilities for macs that need to be updated? Any advice?
