Hi guys.
The "easy" solution simply does not work.
I've put my old mac in target disk mode, downloaded yosemite on the newer one, installed it specifying my old macs drive as the target, it installed, rebooted until I was actually able to boot the OS up on the newer mac and it went through all of it's setup stuff, it even let me browse files and so on so forth and start applications, but I can not put pike's boot file on it and repair permissions because the repair permissions button is greyed out as if my disk isn't even an OS startup disk.
What then is missing during the process, am I not supposed to run initial setup on while still connected to the newer mac over firewire?
Because leaving it connected until the OS is all up and running makes it only work if connected to that mac over firewire, but not in it's own older hardware at all.
Could someone PLEASE shed some more light on this for me, I really am trying to get this working for my charity and it's just not working due to steps being missed in the thread. (just like the one about selecting my newer Macs HDD as the startup disk after I disconnect the target disk that just got yosemite installed over 10.6.8)
Having said all of that, I must say that Yosemite is behaving quite confusingly.
It didn't see my target disk in the old mac as an OS disk so as to let me repair it's permissions, so I naturally thought something went wrong, since that would indicate that it is a data drive only, if it doesn't let me repair permissions that is.
However, upon bootup, it simply proceeded to let me boot it up just fine, which it didn't before, presumably because I had a second boot-up hdd in it, and it appeared to have never made my main had in the old one a bootable one.
However, what amazes me the most is that pike's boot.efi worked without even repairing permissions and simply booted after a mere copy paste into the two locations mentioned in the previous post.
So I am now actively running a permissions repair on it after it has simply booted up all by itself.
Is that all that is required then, to merely install the os from inside a newer mac onto an older one which is in target disk mode, let it reboot and all until it comes up with the newer os starting up from the old drive on the new hardware, shutting that down and replacing the boot.efi files in both locations after a second target disk mode setup?
Of course, apparently there have to be no other bootable os drives on the old mac. Perhaps disconnecting any other hdd from it will male it ultra-sure that it won't mess itself up.
Is it even worth repairing permissions afterwards since it boots up on the old mac just fine?
Of course I'll install the yosefix before we install any OS updates, especially upgrades like El Capitan.
Thanks!
