You really don't want to change any username.


Make a new Admin for yourself.

Starts up like the first time you buy a new Mac, but after filling in all that info again, you should have access to the computer and the other Users & files will still be there... give the new User a different name than an existing one.

Sounds like Disk corruption for sure...


Tough without the Install disc, but some things to try...


Does it boot to Single User Mode, CMD+s keys at bootup, if so try...


/sbin/fsck -fy


Repeat until it shows no errors fixed.


(Space between fsck AND -fy imoprtant).


Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

We need more info to see if it'll run a newer version of OSX.


If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...

So, you have an Intel iMac. You can bypass Leopard ($200 from Amazon) and go straight to Snow Leopard.


Requirements for OS X 10.6 'Snow Leopard'


http://support.apple.com/kb/SP575


The OS 10.6 Snow Leopard install DVD is available for $19.99 from the Apple Store:


http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard


and in the UK:


http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard


but nobody knows for how long it will be available.


When you have installed it, run Software Update to download and install the latest updates for Snow Leopard to bring it up to 10.6.8, or download the combo update from here:


http://support.apple.com/kb/DL1399


Check via Software Update whether further updates are required.

Yes, depends a bit on how much RAM you have, 10.5 will be a bit faster, 10.6 a lot newer...


Leopard requirements/10.5.x...


* Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor


minimum system requirements

* DVD drive for installation

* 9GB of available disk space (I say 30GB at least)

Classic/OS9 Apps no longer supported.


May be available from Apple again...

Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...

Which apps work with Mac OS X 10.6?...

It's been pulled from the online store & Apple Stores, so you have to call Apple to buy it, last I heard.
