Hi
Due to a hardware issue, my MacPro 3.1 does not save nvram. This meens that I cannot select a disk to boot, the information is lost at each startup. So the mac always boots on the first drive. I want to know if rEFInd use the nvram to store something to start? Is it possible to install rEFInd to be the default way to start for the Mac?
And just to be sure (because my english is not so good), can rEFInd replace the startup panel by selecting a HD to boot, never mind if it is not a pref pane. But I want to know if without action, the previous selected drive boots up.
Thx
V.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
UEFI BIOS keeps boot list and queue in NVRAM, so it's required anyways.
Try to reset NVRAM. I've done it few times to repair startup on some 2nd/3rd gen of Intel core i CPU-based PCs, which are most vulnerable to NVRAM quirks AFAIK. Software required depends on BIOS type, and sometimes flashing whole UEFI-BIOS is needed (BIOS program, boot code and NVRAM), but I have no idea how it goes on Macs.
