The same problem here. I just recently bought MacBook Pro 13" 2019 1,4 and soon after updated the iOS to Big Sur. Ever since then it started taking too long to start up the computer, and every time it is put on sleep or logged out it takes between 1-2 min to enable me to type in the password or scan my finger print. My old MacBook Air from 2014 seems to work much faster than the new MacBook Pro. I tried cleaning up all the cache memory, closing down all the applications opened before I log out, nothing helped. Seems that the Big Sur is really pain for Mac. Cannot see ay reasonable solution to this. Anyone has any suggestion?
