Note: This update requires you to be running 10.6.2. You can download and install the 10.6.2 update from here.
Note2: DO NOT update if you have a Celeron Processor, or any other processor that required you to use a special kernel when updating to 10.6.2. Simply follow step 4a to install the legacy kernel for 10.6.3.
Snow Leopard officially received its third major update, Snow Leopard 10.6.3/10.3 kernel, just over two months ago (sorry about the delayed post). Much like the update to 10.6.2, 10.6.3 is a fairly seamless upgrade. Replace a kext or two and you’re back on your hackintosh feet. Plus, you’ll now have USB 2.0 again!
To update to 10.6.3 from 10.6.2, simply do the following:
1. Delete SleepEnabler.kext from /Extra/Extensions
2. Download the 10.6.3 update. Weighing in at over 700mb, you’ll want to grab a cup of coffee while you wait for the download to complete.
3. Download the new SleepEnabler kext for 10.6.3. Don’t do anything with it yet.
4. Install the 10.6.3 update, but don’t restart yet.
4a. **This step is ONLY for users with a processor that required the legacy kernel on 10.6.2** – Run the 10.6.3/10.3 Legacy Kernel package.
5. Navigate to /System/Library/Extensions/ and remove IO80211Family.kext.
6. Restart and then login.
7. Copy the SleepEnabler.kext from step 3 to /Extra/Extensions/
8. Reboot. Note: Some users report a Kernel Panic during this step. If you experience a KP, boot with the -x flag and delete SleepEnabler.kext in /Extra/Extensions.
9. Navigate to /System/Library/Extensions/ and delete AppleHPET.kext. This will allow your USB to operate at 2.0 speeds.
10. Reboot and enjoy!
After updating 10.6.3 and following this guide, your USB will be operating normally, sleep will be working (on battery), wifi will be working, and audio will be functional (albeit with microphone inoperable and audio out inoperable upon waking from sleep).
