New Anti-Consumer MacBook Pros - Teardown And Repair Assessment - Apple Silicon M1/M2
No surprises here. Just like the lockdown on iPhone screen and part replacements, Macbooks suffer from the same Apple's anti-repair and anti-consumer bullshit. Battery glued, ssd soldered in and can't even swap parts with other official parts. 6000$ laptop and you don't even own it.
I just recently had a 2020 gen MacBook pro die on me. When I took it to the genius bar, they said that it was a power issue that they couldn't repair unless they changed the whole logic board which would cost me $500 and without the ability to recover the data on the soldered SSD. What's worse is that they sent me to a 3rd party data recovery company to recover my data for $1200. I ended up declining the data recovery and just accepted that my data is gone and bought a thinkpad to replace the laptop.
