ggrpitt Posted January 3, 2018 Share Posted January 3, 2018 I DID consider upgrading to Sierra/High Sierra but the upgrade via the App Store did not work. Fortunately I had a Carbon Copy Clone of the old system. Has anyone done a direct upgrade of an Optiplex 9020 running 10.11.6? Opti 9020 (Double Boot in separate drives -10.11.6/Win10) CPU: i7-4790 Graphics: HD4600 Samsung 850 SSD 250 G (OS X) WD Velociraptor 300 G (Win) Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted January 4, 2018 Moderators Share Posted January 4, 2018 Just need to upgrade Clover to latest and enable FixHeaders in Config file but I don't recommend it. Sierra might be a better choice. With Sierra sleep/wake works, on High Sierra, system reboots on wake. No fix so far if your main graphics is HD 4600. Didn't test with any other cards.

brousseau6933 Posted March 13, 2018 Share Posted March 13, 2018 Doesn't work neither with NVidia card...I know that some people have troubles with real Macs and sleep/wake since HS so maybe 10.13.4 will have some fixes...In my case: Dell Optiplex 9020 Haswell not working but no troubles with HS (it was a test only, I reverted to Sierra) on my Gigabyte Haswell board.
