shinho73 Posted August 1, 2019 Share Posted August 1, 2019 (edited) I have a very old PC with intel core 2 duo and Geforce GT 620. This pc does not have AHCI, only IDE. I was able to install Mojave with some AHCI fix kexts. However, when I boot, gets to log in screen, and the screen goes black and restarts. On verbose, does not show any error. Just boots up to the log in screen and restart. Same thing with Sierra and High Sierra as well. But on Yosemite and El Capitan, no isssues. Just that on El Capitan, it would not reboot and shutdown. On Yosemite everything works. Any input will be greatly appreciated. Thank you. Edited August 1, 2019 by shinho73 delete some words Link to comment Share on other sites More sharing options...
shinho73 Posted August 2, 2019 Author Share Posted August 2, 2019 Manage to install Mojave. Using High Sierra telemetry plugin fixed the problem. The GT 620, Open GL app shows "value_metal". Mojave recognizes the GPU, but no acceleration. Is this fixable. Any help will be greatly appreciated. Thank You. Link to comment Share on other sites More sharing options...
