Does anyone know if the hardware diagnostic test has changed in MacOS Big Sur? When I restart my machine and hold the "D" key, it appears to send it into recovery mode.
Got a tip for us?

What Mac?
Intel and Apple Silicon are different. https://support.apple.com/en-us/HT202731
Diagnostic mode does not depend on macOS. It is part of the EFI firmware.

I know several people on here have had problems getting the test to load on the M1. Apple has been made aware of the problem and is supposedly working on a fix.
