. I have version 10.6.8 at the moment... how do I update this?
As Terence Devlin said, the upgrade to Mavericks is free at the AppStore. Open the first tab at the AppStore (Featured) and you can buy it for free, if your Mac can be upgraded to Mavericks.
But before you do that, check the applications you need to use for compatibility with Mavericks, for example at Roaring Apps: http://roaringapps.com/apps?index=a
PowerPC applications can no longer run on Mavericks, some device drivers may not be available as Mavericks compatible versions.
To prepare for the update take these precautions:
- Make a full backup of your mac, including the applications libraries. In addition to the TimeMachine backup a bootable clone is very useful, since it enables you to revert easily to the old system.
- Update all applications to there latest version, thatare available on Snowleopard.
If you find, that the Mavericks upgrade would make too many applications redundant, consider Terence Devlin's second option to buy the boxed iLife version.
