I have a MacBook Pro 2016 13'
8 GB 1867 MHz LPDDR3
Intel Iris Graphics 540 1536 MB
I'm having lag problems in App Store and Safari since day one of this update, and still it's almost a year of Big Sur and no fix at all.
I just can't understand why Catalina runs like flash and this one runs buggy... its a one year diference of update, not 5 or 4 years.
I'm going back to Catalina and wait for it to be fixed or just wait for the next major updated I guess.....
