I have upgraded yesterday to Mac OS Big Sur, I am having inconsistent performance. It is slightly slower but the main issue is when connecting to external display LG ultra fine (sold by Apple) I get pixilation and have to restart several times. Also have to disconnect and reconnect the thunderbolt port. It’s getting annoying.

Even camtasia 2020 cannot record system audio because the driver fails to instal .

I wish I listened to MKBHD recommendation. Actually his video was after I upgraded.


Please Apple let me downgrade or change this device.
