MacMini won’t boot with a SSD on the Thunderbolt3 port
I bought a Crucial 1 TB SSD and plugged it into my Thunderbolt 3 port.
And when plugged in, my mac (2018 Mac Mini with upto date OS) it just won’t start. With verbose mode, no text appears on screen: just the apple logo.
Note: macOS boots from the internal SSD, this external SSD is just a plain storage unit.
What I’ve tried :
- Some have speculated it could be related to the eGPU, but unplugging the eGPU doesn’t solve anything.
- I tried removing the T2 security “Boot from SSD” - no change
- I’ve checked the boot order, it’s set to the internal SDD
- I have 3 HDD on the USB ports that work just fine
So far, the only solution is to unplug the SDD, and plug it back (which is not really a solution, is it ?)
