Upgrading from 10.5.8 to 10.6

My iMac currently runs on OS X 10.5.8 and I need to upgrade to 10.6 Snow Leopard. I know that I can purchase the disc from Apple, but when I called, I discovered that my technical support has expired so I can't call them without paying £35 for a support package. Is there another way I can buy 10.6 from Apple? I'd rather not pay £100 + on Amazon.co.uk...


Thanks in advance to anyone who has the time to read and answer this.

A standard installation of 10.6.3 over 10.5.x will replace only system components; it will not touch personal data, preferences or applications (other than the core Mac ones such as iTunes, QT, Mail and Safari).

The main change is that it strips out all code support for the PPC chips (G series), and will run only on Intel.


When installing, be sure to select Rosetta from the optional installs; it's a code translator for running applications originally written for PPC syatems (AppleWorks, MS office up to 2004, many Adobe apps and numerous device drivers).


Yes there will be software incompatibilities and some drivers for older printers and particularly scanners will need updating.

I can't emphasise enough the importance of having a backup before beginning any upgrade. Preferably a bootable clone of the current system.

99% of installations go smoothly, but there's always the chance of a previously unnoticed fault or a file system irregularity on the HD causing problems. So do please backup first.

(You should in any case always have a backup in case of hardware failure).
