Can not boot up Yosemite install without installer USB
It's been a while!
So, I came across two old SFF setups that I could buy for just a couple of bucks. One of them is an NEC power mate VL280. I installed Yosemite 10.10.1 on it which I updated to 10.10.5 without problems. Everything is working fine, except for 2 little problems:
1. I can't boot up from my harddrive. Chameleon gives me the error that mach_kernel cannot be found. It boots fine when I use the Yosemite install USB to boot, though. When I link to the kernel in /System/Library/Kernel/ in the boot arguments, my computer just reboots.
2. Whenever the computer goes into standby, my monitor refuses to power back on.
Intel Core 2 Duo E6550, 2.3Ghz
Motherboard is unknown, since it is produced for NEC, but it has the Intel G31 or G33 chipset
Sapphire Radeon HD 6450 1GB, Low-Profile
4GB DDR2 RAM, 667Mhz
I am using Chameleon v2.2svn r2286 as built-in boot loader.
Thanks in advance,
