looks like developer version is better than RC version on MacBook Air M2
I tried to clean install RC or Stable version many time but sometime facing with bug from installer will damage os and bad performance.
14.4 Beta 2 first time update and restart and seen kind of installer screen and turn on still with 14.4 beta 1.
Tried to run update from setting again and restart. Finally update to last version 14.4 beta 2.
Still Great
