Updating Lion to 10.7.4 on a PC

Apple released the Lion 10.7.4 update on May 9 and it will install smoothly on your computer (assuming that Lion went smoothly).

As always, you should keep some kexts and Multibeast around in case things go sour. If the install fails, install another Lion partition and install the update from the secondary partition.

Now that the details are out of the way, in all likelihood, you shouldn’t need to fix anything. If you added sleepenabler, it is best to remove it.

It has been reported that audio kexts may fail and if you edited your graphics kext, that may have been replaced.

Once this is done, you can just download and install the 10.7.4 combo update on your fresh Lion system or 10.7.3 system. You can then restart the computer and Lion will work. I haven’t tried the Software Update, but I would assume that since updating it manually went smoothly that Software Update would as well.

If anything breaks – which didn’t happen in my case – you can just run multibeast or kext helper and fix it as you would normally. If you are using a modified kernel, you will need to check to see if one is out and then install it before restarting.
