Hi all. So my question for those that know about the boot process.
I have an officially unsupported RX470 in my machine, which is also fitted with at least three different boot volumes at any one time, (I always have at least two different Mac installs and one windows install, all on separate disks). Of course it doesn’t allow me to see the boot picker.
My question. The Mac recognises ⌘-R and uses that to boot into a volume it recognises as Recovery. Does anybody know/think if it would be possible to write a script that lives in NVRAM or similar that would allow me to do something like key in ⌘-W during boot to select a pre-determined drive?
I have a PowerMac G4 running Tiger to experiment on. Whilst its very old it should help me learn what to do and if it’s at all possible before I try it on my old Mac Pro.
Or is it all far too much hassle and risk?
Thanks guys.
