Last week my iMac (20", 2.4 ghz running 10.6.2) got incredibly slow. I've checked all the usual stuff - recently installed programs, Activity Monitor, reset the PRAM, restarted many times, software update, verified disk, repaired permissions etc etc. The only thing I know is that the problem exists on my regular admin account, but not on an extra account I have, and not on a new admin account I just set up. At this point I don't think I can figure out what exactly is causing the problem on the old admin account. 1) Is it possible to let my new admin account access all the docs, mails, movies, music, prefs etc in my old admin account? How? I initially thought I could move the important things over to my new account manually. I tried to copy my mail folders in my Library over to my external harddisk, and then moved them to the correct place in my new admin account. I changed the permissions to read and write. But Mail won't open in the new account, and tells me it's because of the permissions on the mail folder. 2) Is it possible to use my Time Machine back-up to let my new admin account behave as if it's my old account? 3) Should I just reinstalled SL and create a new account and then restore from Time Machine when logged into that account? I have to do something, because the old account is waaaay too slow to use for any length of time. But I don't know the best way to go about this. I realise I might just reimport the problem as well... Thanks in advance for any help!
