macguru8 Posted October 30, 2017 Share Posted October 30, 2017 Hello taddeusz, https://osxlatitude.com/index.php?/topic/10093-e6420-second-sata-port-not-working-in-macos-1013-high-sierra/ did you do a fresh install for High Sierra to work? I have the same E6420 and can't get High Sierra installed. Also, are you using UEFI? thanks Link to comment Share on other sites More sharing options...
taddeusz Posted October 30, 2017 Share Posted October 30, 2017 Mine was an upgrade, not a fresh install. Also using legacy boot, not UEFI. I tried once but I couldn't get Clover to boot with legacy mode disabled. Link to comment Share on other sites More sharing options...
