I am running Tiger 10.4.10 on a new MacBook and this morning, after I hade been moving things to/from the dock I noticed mail stopped working and a couple of apps wouldn't run. Turns out I'd accidentally trashed the main User Account thinking I'd only binned an Alias Upon re-booting the macine it created another default User Account in my name but it's contents were effectiveky blank. I the found the old deleted User acount in Trash, copied it back to the desktop and basically swapped all the folders in it for the folders in the User account the system had created upon re-boot (including library, desktop etc etc). All is working fine now It has now been strongly suggested that I do a complete re-install of the OS using the Archive and Preserve option to get a clean system. I am a little retiscent to do this merely beacuse I don't want to create more problems than I have now solved. It seems like it may be overkill BUT, nt knowing enough about Macs (and the person giving the advice clearly does), I'm just after a broader perspective before I go down this route. Is a re-install so necessary for this problem (esp as I plan to upgrade to Leopard when it comes out)? Will what I've done (and what i did to fix it) have created so many problems that not fixing it properly with a COMPLETE re-install is only asking for trouble with problems ultimately building up on an OS which is now perhaps in a mess? Or, am I OK to leave as it is (esp in light of the Leopard relesase)?
