I'm still testing how the B550 Vision D works with an un-flashed TB3 chip, and the replaced WiFi/BT in the M2_WiFi slot. I'm using Catalina 10.15.7 and public beta Bid Sur with both OC 0.6.1 and OC 0.6.2.
This board is very inconsistent in how it does or doesn't mount my TB3 drive with various combinations of OC and macOS.
For example, in one run with Big Sur public beta and OC 0.6.1:
Power off 10 seconds, power on, startup, NO TB3 mounted. Hot Plug - NO TB3 mounted. Reboot, NO TB3 mounted. Use Apple Sleep - does not sleep and system hangs. Reset button to restart - NO TB3. Shutdown. Startup and TB3 drive is mounted in OC Picker and appears in Finder. Use the
Jettison app to unmount and remount. Unmount and unplug drive, then hot plug and the TB3 drive is mounted.
With the public beta Big Sur and OC 0.6.2 - TB3 does not work at all for me. I'm unable to get my external TB3 drive to mount under any conditions. I used the VISION-D-N0-SLEEP EFI file CaseySJ posted on page 1.
With Catalina 10.15.7, and OC 0.6.2, TB3 drive mounting is a mixed bag:
•
Once after turning the power off for 10 seconds, then starting, the TB3 drive was displayed in the OC Picker, and was mounted in Finder.
• Usually on a cold or warm boot the TB3 was not mounted.
However, selecting "Sleep" from the Apple menu the B550 Vision D would momentarily turn off, then on, then return to the desktop and the TB3 drive was mounted. Selecting "Sleep" again would put the B550 into a powered-off sleep state (no lights on). Hitting a keyboard key would wake the B550 and the TB3 drive remained mounted, and everything was functional. Using the
Jettison app the drive could be unmounted and remounted. Generally hot plugging the TB3 drive didn't mount it.
Who would have thought that putting the B550 to sleep would result in mounting a TB3 drive?
Based on my observations, TB3 chip flashing will be required for the B550 Vision D.
