a critical software update is required for your mac

Yes, I could successfully install: High Sierra, Catalina, Mojave, Monterey from USB. Somehow this ended up with a clean wipe of the SSD plus attempt to re-install from scratch. As she couldn't install the update from the package ( didn't know how to?) she rang up Apple support. Highly unlikely from my understanding, and probably actually advisable since that could reset whatever may have gone wonky.įew more days later she called. She also had downloaded High Sierra to try and do the upgrades herself and wanted to check with me whether that might interfere troubleshooting the sound issue. Could this be due to the screen replacement?Īs the screen assembly replacement only requires removing the wifi antenna bar only to get done, just couldn't see how that would affect it. No worries.Ĭouple of days later she called about the touch bar seems to not be working when trying to adjust the sound volum. We discussed the OS upgrade, she reckoned some relative might be able to do it for her. The OS was still on Sierra so I sent a quote to upgrade to Big Sur, could take Monterey but I suggested holding off on that for the next couple of month as it's only been freshly released.Ĭustomer collected after being shown all working fine. I did notice the sound level wasn't high but it was sufficient for me whilst working on it. Replaced the broken screen assembly on this MacBook Pro 2017, everything worked well.
