a few years ago I got an old Mac (2009 version). I tried to fix it but I gave up after days of workimg.
Last week i tried it once again. It seems that there is no (totally broken, I dont know) Hardd Dive, the EFI Mode doesnt work really (Mouse and keyboard dont work, the GUI looks really strange, difficult to describe, also a MacOS-CD couldn help at all!) I came trough with a Ubuntu CD and installed it on my external Hard Drive. But now I have some Problems, where I need our wisdom!
Because EFI seems to be broken I have to start with the UbuntuCD and start from there the installed ubuntu on the external Hard Drive. When i try ALT or something else. EFI is totally unable to let me boot from my external (wired graphics and no control over keyboard etc) Is there a way to install EFI new or get a way around it? (like EFI on the external?)
From what I understand EFI controls the fans, which makes sense, because they are also broken. They are ALWAYS on fullspeed even when i just started the MAc,even in EFI, in Ubuntu, in LiveCD... How can I fix this? Ok the Mac seems to get hot but it shouldnt listen like an Airplane...
Thx for your amazing work here
