Updating mac os 10 2
Individual Updates are also known as Delta Updates.Combo Updates update the base version of a Mac OS X release to the version specified in the Combo Update, including all intermediate updates.Individual Updates update one version of Mac OS X to the subsequent version.For example, the Mac OS X 10.7.4 Update updates Mac OS X 10.7.3 to version 10.7.4.They can also cause problems, particularly if your Mac should freeze, lose power, or otherwise prevent the update from completing.When this occurs, you end up with a corrupt system update, which may manifest itself as simple instability: occasional freezes or the system or applications locking up.Since Software Update only downloads and installs system files that need to be updated, you can end up with some files being out of date with respect to other system files.
A mathematical improbability exists to test all combinations of software and hardware compatible with Macs.
Although the Software Update problem is infrequent, and most Mac users will never see it, if you're having some unexplained issues with your Mac, the Software Update problem could be the culprit.
Eliminating it as a possibility is very easy to do.
As of the writing of this FAQ (Frequently answered question page), I've updated every Mac OS X version on an Intel Mac through 10.4.11 to 10.11 using the method of this FAQ.
I have a Power PC Mac right now standing at 10.4.8, which I could upgrade to 10.4.11, except I have some old games which won't run on 10.4.11.
