The fact the update works at all is a testament to how well tested the software is. A mathematical improbability exists to test all combinations of software and hardware compatible with Macs. Just because you've seen an issue which appears on a bulletin board, or is reported to you by a friend in a Mac OS X update, it does not mean the update is itself bad. I have a PowerPC 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. Why should I read this FAQ?Īs 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. Pre-MaMacs which are post JanuMacs can use the 10.6.3 retail installer.

Post MaMacs without the firmware will need the original system discs that shipped with the Mac to restore the system. Pre-JMacs do not have recovery unless a firmware is installed first. But only do so after trying other tools on my Mac OS X Speed FAQ. When your data is backed up, and your system is hopelessly munged, try the regular recovery mode first. An Internet Recovery option also discussed allows a secure internet connection to restore the original system that shipped with the Mac. Directions for recovery are available for Intel Macs, and M1 Macs, to utilize it on Apple's website. Starting with Mac OS X 10.7, Apple partitioned a separate portion of hard drives installed with Mac OS with a recovery partition.
