I waited a few weeks to update my Hackintosh from Mac OS X 10.8.2 to 10.8.3 in order to make sure any issues were dealt with by others. Instead of using Software Update from the App Store, I downloaded the Combo Update package from Apple. Using the Combo Update is the recommended way of updating Hackintoshes. However, there were quite a few reports of successful updates applied by using the App Store updater.
In any case, after applying the update, my Hackintosh would not boot. I basically had to go through the entire build process again. I actually "doubled up" because there is a new version of Unibeast for 10.8.3. So:
- Remove graphics card
- Use Unibeast 1.5.3 to reinstall Mountain Lion 10.8.2
- Boot safe mode (-x) from HD using Unibeast, then re-download Mac OS X installer from App Store.
- Download new Unibeast 1.7.0 from Tonymacx86, and create new USB Unibeast flash drive.
- Boot from Unibeast 1.7.0 to reinstall Mountain Lion 10.8.3
- Reboot from HD using Unibeast, and run Multibeast. At this point, I still couldn't boot from the HD without Unibeast.
- Reboot from HD using Unibeast, and install Chimera 2.0.1
- Reboot from HD without Unibeast. (Success, finally.)
- Turn machine off, reinstall graphics card, and reboot a final time.
Holy smokes. That only took me a week to figure out, after going through many iterations. Well, at least I'm still saving 30% or more compared to a Mac Pro.
