Something unexpected occurred while updating to macOS.
Something unexpected occurred while updating to macOS.
Your MacBook Pro experienced unusual behavior during the update, including screen issues, flashing lights, and a thick bar under the Apple logo. This could indicate hardware stress or a software glitch. It’s possible the GPU is affected, but further testing or professional diagnosis would be needed to confirm.
typically computers undergo a restart when upgrading from an older windows version to a newer one, but the flashing power light appears different—it could relate to the system restarting during the update. I’m not sure, since I don’t own a macbook; I only have an iphone and an ipad. However, if everything functions properly, it likely isn’t a major problem.
my MacBook Pro model is often criticized for GPU problems. I'm worried it might be failing now. It restarted multiple times during the update, but didn't show any flashing power indicator, beeping, or the thicker progress bar. That was just once. After restarting since the update, it has booted back up normally.
perhaps it was intended to begin the update by reverting to an earlier version, which might clarify why it appeared "basic" and why the flashing LED seemed unusual. Searching for a moment suggests a possible RAM problem or another factor entirely; it seems no one has mentioned GPU issues in my search. It’s likely related to RAM not clearing properly during the restart or the system attempting to read from RAM to complete the update.
Apple states the limit for my system is 8GB, though it's common knowledge that my model can require up to 16GB. This claim isn't backed by evidence. I initially suspected the EFI firmware might be involved, but now I'm focusing on the RAM aspect since I'm using an unsupported configuration.
I haven't received any support anymore. It's a 2011 model, and I still have the original 4GB RAM included. If something goes wrong again, I could consider replacing that part.
Absolutely, I’d never compromise on having enough memory. I had to stick with 8GB because I needed it for my sister’s PC and man. I really hated it when I couldn’t handle all those tabs—like 40 open ones! If you’re not sure how you feel, just think about buying more RAM than you actually use.
I meant reversing the changes, updating the settings, and then restoring the 16GB. Just in case it causes issues later. Absolutely, I wouldn’t go below 16GB for the main system. The 16GB on my Mac can feel a bit tight sometimes, but the 24GB on my desktop is definitely better.
