OS X Yosemite 10.10.3 - Mac Pro 2,1.

[ilegal31]

Hello,


I am on a Mac Pro 2,1 running OS X 10.10.2 "boot.efi replaced", the 10.10.3 update will also break the Tiamo boot.efi?, if so how can I safety update?. Also, I am running an Nvdia GTX 570 on my machine, the web drivers for OS X 10.10.3 running with no issues?.



Thanks in advance for the help.

Hello. You should use, according to the forums the Yosefix [ a fix that replace the boot.efi
every time you restart the computer for the correct - teamo - one ].

I did install the Yosefix and I've been able to update to 10.10.5
