Since upgrading to Big Sur, I have been experiencing slow reboots, crashes, spinning beach balls of death, lagging applications (mail, Firefox, Chrome, MS Office, Notes, Calendar, etc), and very poor battery life. The battery duration went from 6-7 hours of regular use to less than 2 hours of same use. The battery health reports "Normal", but it's anything but normal.
I installed the latest 11.4 patch with no improvement of battery life or performance. The Big Sur has essentially killed my Mac Air. Please fix both battery and performance to pre-Big Sur.
MacBook Air (13-inch 2017)
1.8 GHz Dual-Core Intel Core i5
8GB 1600 MHz DDR3
Intel HD Graphics 6000 1536MB
Thanks!
