Thus when I was notified that it was available, I dutifully upgraded… and then my MacBook Pro Retina wouldn’t reboot. After Update, OS X Won’t RebootĪfter upgrading to OS X El Capitan (10.11) when it was released, I had been generally pleased with the new version but there were a few quirks – like random beach ball pauses – that made me think the 10.11.1 update would address some of them. It seems to have left behind a kext named .kext and once I deleted it, things work again. Before I knew this I installed Malwarebytes to check for spyware/adware causing the CPU usage, then uninstalled it after installing the OS X beta. I am using the Beta version because 10.13.2 had very high CPU usage by the WindowServer process that was fixed in 10.13.3. Update – I updated to 10.13.3 High Sierra Beta 5 and once again was unable to boot. Removed everything older than 2016 after running ls -lat. This time I had to remove kexts from /System/Library/Extensions. Update – I updated to 10.12.6 and once again was unable to boot. Update – This has been an issue for myself and others running OS X Sierra as well. Update – It happened again when I updated to 10.11.4! Even fewer clues this time, additional details and an updated script to remove non-default kext files at the very bottom. Otherwise feel free to read the saga below! Stay off the interwebz.If your OS X El Capitan/Sierra/High Sierra update won’t reboot you can skip to the fix or check here for the (mostly) automated fix script. High Sierra uses a poor early implementation of APFS which was very troublesome. The Sierras were an unmitigated disaster, saved eventually by Mojave… which you can't use without hacking - not recommended if you want performance & you can't hack it right up to a current OS anyway - so don't.
So, as either is an island in the stream, dropping further & further behind 'today', then the only important thing is how each behaves.Įl Capitan was a really good, solid OS. You will be hard pushed to find any new apps that will support that far back - so long as your current old apps still work that's not an issue. Neither will properly be able to interact with such as the App Store - which won't really matter much as neither will be able to use any new apps from it. Keep it offline as much as humanly possible. Both will increasingly require workarounds to connect to the internet - which should really be avoided for either. Not worth upgrading from El Capitan to High Sierra.īoth OSes are equally out of date compared to modern systems. This might get closed as 'opinion-based' but before it does… my opinion )
