Just cant get it to boot/fresh instal + kernel panic


Im trying too fix a mac pro 2008 3,1 3.0 8core. When its starts up it gives a kernel panic.

My first thoughts where that it had a bad hdd. I plugged it in another mac as a slave disk en got all sort of damage reports when using disk utility.

Internet recovery mode

Also when i tried internet recovery it wil not instal en fresh osx.

I got out the old hdd and plugged a new (old) one in. Which was completely erased and format journaled extended.


So ive tried to boot it with a dvd system disk os x lion (command +c) but its eventually gets a hickup and unfortunately shows a round sign with a stipe. Swap out the dvd drive with another one. same thing. new disk, same thing.


next thing i've tried was to make it boot with a instal usb el captain. But when i startup with alt/option pressed it doesn't recognize the usb. and that sucks big time.

Ive cleaned the whole system which was pretty dusty and dirty.

I'm not a mac specialist and little bit out of options. I just cant get this sucker to run which i really want!!

Help/advise please!

Vince, I also had a similar problem and struggled to use USB with El Capitan Instal for so long till I read that my version of the mac pro is not capable of running that OS. Its maximum OS is 10. 7.5. So trying this OS with either DVD or USB. You can download the 'Lion DiskMaker' app from the net to create a bootable USB for the installation. I think I came across an article which seems to suggest that Sierra can be installed on mac pro 2008 but couldn't read all before I lost it. More research is needed.

This is just incorrect, the maximum, operating system is El Capitan. It will not take Sierra without flashing the EFI. Your answer reflects a total lack of knowledge on this machine.
