2021 Macbook M1 Boot Loop Issue Solved
Symptom: 2021 MacBook Pro 16 inch starts a boot cycle then fails. Boot options menu (holding the power button for 10 secs) does not work. Upon start-up, if you aim a light at the center of the screen, you will see the Apple appear for 3-5 secs then shutdown.
- I do not recommend a Recovery attempt if you do not have a recent, solid backup - it likely will not work and you will lose your data.
- I do not recommend a logic board replacement, again you will lose your data... first attempt a LCD Screen lid angle sensor and Display replacement. (Cost as of 2023 with labor and parts was about $800.)
- And lastly (Sigh Apple) you cannot pull the hard drive it is embedded in the logic board.
Hope this helps you.
