Moderators Jake Lo Posted December 18, 2019 Moderators Share Posted December 18, 2019 What did you change / update prior to the reboot? Need more information... Which MacOS are you running? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 18, 2019 Administrators Share Posted December 18, 2019 Darwin 17.7, so High Sierra it would appear... I've split OP's threads into 3 x separate Mojave/El Capitan/High Sierra threads for clarity's sake; especially as everything had just been added to another member's thread related to HD520 graphics acceleration under High Sierra on that E7270 platform.

aufannada Posted January 9, 2020 Author Share Posted January 9, 2020 I am so sorry I late to answer the question because I was sick last time. I didn't change anything. The problem appears after I update with Security Update 2019-007 (High Sierra). A then when reboot I can't boot to desktop. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 9, 2020 Administrators Share Posted January 9, 2020 Try and boot in single-user mode, then manually rebuild your cache. Link to comment Share on other sites More sharing options...
