Get ready to unleash the fury of your inner Leopard with one of Apple’s biggest updates, Mac OS X 10.5.5. Weighing in at 321MB (Cool, huh?), there are dozens of bug fixes and additions to make this a real “worth while” update for your fully licensed official Mac or your Hack. You may start the drooling process now.
It took me a day to get all of my stuff together and pull this update off. I use my HackBook Pro in a production environment, which means I cannot be too far away from my Time Machine drive. As the excitement mounted, viewers of this blog had already dove into it — head first, and pulled it off with mixed results (Read the comments below for more information). A lot of what you did getting to 10.5.4 will save you some time because from what I’ve gathered by updating from 10.5.4 to 10.5.5, it’s mainly just copying over a few key kexts that get replaced with the update, repairing permissions, etc. etc.
1) First, download the update directly from Apple’s website. I’m not sure if it matters where you get it but this is how I did it. I’m sure Software Update is safe but don’t take my word for it. You can grab 10.5.5 at http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1055update.html
2) Before you run the downloaded file, open up Terminal and type “sudo su -” without the quotes. Enter your user password and then type “while sleep 1 ; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext ; done” without the quotes. Keep this window open while you run the downloaded update and install it. It should complete in a few minutes and ask you to reboot. Before you reboot, exit the Terminal script by holding down Ctrl and pressing X (Ctrl + X). Close Terminal and hit the button on the Update to reboot your computer.
3) Once you reboot your screen may go blank or your system might auto reboot. Don’t panic yet. Reboot the system again, this time booting with “-v -f -x” and let it do it’s thing. Your screen will probably still be blank. Let it run until there’s no more CPU or HDD activity. Reboot again with normal flags (-v -f) and let it go to sleep. Wake it up and you should be seeing the login window. If you auto login you can swipe your mouse over your hot corner (You kept that hot corner, right?) and you should see your desktop although it may appear unstable. Log out and back in. Boom!
4) Your wireless is dead, your battery doesn’t display and your sound isn’t as groovy as it used to be. Time to step back in time. Dig through your Extensions.bkup on your desktop and locate a few key kexts. Grab the latest version of Kext Helper b7 and prepare to do battle with permissions. Rather than re-patching, re-applying, etc. the steps we did in 10.5.4, we’re just going to copy over the good stuff we know worked before.
5) Fire up Kext Helper b7 and start dragging kexts into the window. Enter your password and click Advanced. You’ll want to make sure the following are displaying in Kext Helper b7: AppleHDA.kext, AppleACPIPlatform.kext, AppleAHCIPort.kext. Hit the install button and then hit Kext Permissions and Tag Cache Rebuild. Hell, hit them a couple times! Now close out of Kext Helper b7 and do the Disk Utility dance by repairing disk permissions a couple times. I ran it 3 times just to make sure. Your milage may vary.
6) Reboot. You should have everything but the battery meter. Download PowerManagement.bundle again and do your thing. Make sure you completely remove the old one (“rm -fr PowerManagement.bundle” in Terminal). Repair and reboot again. Alternatively you can back up your original PowerManagement.bundle from /System/Library/SystemConfiguration/PowerManagement.bundle.
This should work for everyone who is running 10.5.4 and possibly those running earlier versions of Kalyway’s DVD. These are as clear of instructions I can give and I must admit, they’re a little less user friendly than my original tutorial. Hopefully you’ve been following me on this blog and know a few things by now. Be sure to run Time Machine, Super Duper or Carbon Copy before you dive into this if you care about your files. After you upgrade to 10.5.5, there are some minor software updates awaiting you. Nothing major, all risk- and error-free.
While your milage may vary, the chances of you “hosing” your system is very slim. Even with a kernel panic, blank screen or spinning beach ball, not all is lost. Remember, this isn’t Windows Vista. You aren’t required to re-install for every little hiccup. Play with it, have fun, and post your success/failures here with screenshots.
NOTE: 10.5.5 doesn’t wake from sleep for some reason. Even after trying the usual methods. We may have to wait for a kernel patch or additional kext to restore it. I’ll start looking into the issue this weekend if nobody posts something here first.
