The week started with myself struggling with BigSur upgrade rendering my laptop useless for nearly a full day. Laptop booted fine on recovery and safe mode but not in standard mode. Internet seem to be filled with these issues. Few observations i had:
- Macbook Display resizing is graphics card heavy and as such causes sluggishness on display. Stick to recommended size if you want less load on system.
- NVRAM or SMC Reset are good first bet. However most of the time the issue is not solved by them now a days.
- With Big Sur kexts are not loaded normally rather kernel has them included
Answer to my problems came in form of a obscure comment
