SUCCESS! Dual Booting ATV/OSX with Internal Drive

7 posts in this topic

Recommended Posts

I've got OSX dual booting by installing OSX to the media partition and it works great. It doesn't interfere with ATV OS


I essentially Installed a fresh copy of osx to a 3.5" hard-drive(hackint0sh). Then popped in the ATV drive to my pc along with the fresh install. Then used Disk Utility to recover the osx partition from the 3.5" to the Media partition making sure to not reformat/erase partition. It will coexist with the Media/Scratch folders on the 4th partition.


Setup the usual mach_kernel/boot.efi mod using semthex's kernel and the guide from appletvhacks.net.


Then Bless with


bless --folder=/mnt/System/Library/CoreServices --file=/mnt/System/Library/CoreServices/boot.efi --setBoot --nextonly


This will tell it to use the boot.efi file from the media partition and boot osx, but only on the next reboot....


I wrote a script that does the bless command and then reboots automatically


Now all we need is someone to write a plugin to call a script to bless and reboot so we can do it from the atv menu and not have to use ssh.


To get back to ATV OS you would just need to reboot.


Another Interesting thing I found was my AppleTV has a 1.5ghz i'm going to run some xbenches to confirm that it's actually performing at this.

After bless I'm rebooting back into ATV.. noticed iMags had the same problem (over on Hackint0sh).. curious if anyone else is having problems getting bless to do its thing?

He hadn't copied the correct boot.efi file into the OSX install on the media partition.




ls -al /mnt/System/Library/CoreServices/boot.efi
-rw-r--r-- 1 root wheel 298800 Apr 6 14:07 /mnt/Sysetm/Library/CoreServices/boot.efi


Check that your size is also 298800.


Copy it from the OSBoot partition.


Also From ATV SSH


sudo cp /Volumes/OSBoot/System/Library/CoreServices/boot.efi /mnt/System/Library/CoreServices/boot.efi
