MacBook Pro (Retina, 13-inch, Mid 2014) updated from 11.6.3 without problems, with user-installed internal 480 GB SSD, external display, gigabit ethernet adapter, two USB HDDs, Apple Keyboard. As with other updates, only quirk was that, after update finished (taking ~20 minutes with more than one boot in process) I had to raise and lower the display in order to get login prompts to the external display.
I had experienced some sleep issues before (Catalina and Big Sur) and run with Power Adapter plugged in and:
- TimeMachineEditor set to backup every day at 3:32 AM
- "Battery" Schedule set to wake up every day at 3:31 AM
- "Battery" Power Adapter with all but "Prevent computer from sleeping automatically..." checked
- and sleep settings as shown below
$ pmset -g
