I've got ridiculous speed problems on my vintage iMac now even after Apple assistance improved things for a couple of days so I'm thinking about a clean system install... how do I actually go about that without losing my essential files such as Mail? I'm assuming I don't have to go back to the original system disk? At the moment I'm backing-up in Time Machine.

The Time Machine backup will save everything. Below are links to the path you would take. Use the Erase option in the third link before reinstalling. Take note when reinstalling it will take a while to download the installer, it's a few gigs in size.

Follow the links in the links above to show how to erase and reinstall.

If you want it totally clean, manually reinstall apps, and migrate manually from Time Machine, and want to restore Mail manually it's a little tricky, let me know if that's what you want to do.

if you restore automatically from TM I would suggest not restoring System and Network settings, you'll see the choices come up at the beginning of the Restore process.

Scroll down to Select Items to Migrate in this link;

Also it may be good to not Restore applications, it may bring over stuff that is slowing it up, only the User/s. You can then reinstall the apps.

Let me know which course you want to take we can go into more detail.

Great, thanks Reboot. I'm going to have to think about whether to go for a completely clean install or I might even move up to a new machine at some point so that what happens to this one will become a little less important.
