According to applehacks.net the procedure is as follows:
About step 5: my MacBook Pro 5,5 can't boot Tiger, since the earliest it shipped with is Leopard so I wouldn't be able to boot the ATV's drive, however, I'm wondering if step 8 is really necessary. I have the install disks for an iMac Core Duo which are 10.4.11,beyond 10.4.8 which they claim you need to update to. Hopefully that would mean that the ATV would boot in to the set up process when the rest of the steps are carried out?
And yeah, I know there are images for 10.5, but I'd prefer 10.4 as it should be faster and everything I need is supported under 10.4 (also it was the first version of OS X I ever used - on a dell no less - so I have a soft spot for it
).
Could anyone who has performed the procedure share some words of wisdom?
1) remove the drive from the Apple TV
2) back up your drive! Make an image of it (see the harddrive upgrade tutorial for this)
3) Connect the drive to a regular Mac (use a Firewire or USB drive dock)
4) Install OS X (Intel version) to the drive (we suggest a slim install – no printer drivers etc.)
5) Boot from this drive, and set it up as you would like it. Make sure you do updates so it is at least 10.4.8.
6) Reboot to your normal OS X install.
Ok, you now have your fresh OS X install which will form the base of the customised OS X you will need for the Apple TV.
7) Remove mach_kernel from root of the drive containg the ATV install.
8 ) Replace it with the customised mach_kernel that you’ll find on Hackint0sh.org.
9) Replace /System/Libary/Coreservices/boot.efiwith the same file from your backup of the Apple TV OS drive (OSBoot partition).
10) Run bless:
bless --folder=/Volumes/OSBoot/System/Library/CoreServices --file=/Volumes/OSBoot/System/Library/CoreServices/boot.efi --setBoot
11) Delete all the Nvidia kexts (all beginning with NVD, there should be 5) from the target drive (in /System/Library/Extensions).
12) Transfer the drive back to the Apple TV
13) Turn the Apple TV on and cross your fingers.
