    [Guide] Install High Sierra or Mojave on the Dell Optiplex 7010 / 9010 Desktop PC - Revision II

    Update on this - it looks like the NVME drive has a hardware problem of some kind. After making a full clone backup of the non-booting NVME drive, I tried restoring/cloning a known, good backup to it and booting and it would not boot all the way up (black screen). (The known backup is on a...

    Looks like we might have opted in to 10.4.6 18G9323 Security Update unintentionally, and 7010 w/NVME won't boot. Errors are IONvmeController: HandleCompletionErrors( ... ) disk2s1 device error And gets stuck in a boot cycle repeating this infinitely. Has anyone else seen issues with this? I...

    It would be great if we could have an OpenCore Big Sur guide for Optiplex 9020 for those who want to engage that build. I wouldn’t jump on it as my Catalina setup is stable but eventually would be interested. Especially if the power mgmt is more stabilized. It would be interesting to see how...

    [Guide] Install High Sierra or Mojave on the Dell Optiplex 7010 / 9010 Desktop PC - Revision II

    Thank you @trs96 for the quick reply and information that offered help. I appreciate it! Based on what you said, I decided it was too hard to repair/patch (and I don’t have time at the moment), so I restored from a backup that wasn’t too old (thank goodness for full clone backups to spare...

    [Guide] Install High Sierra or Mojave on the Dell Optiplex 7010 / 9010 Desktop PC - Revision II

    I am running Mojave on my 7010 based on the exact install sequence provided by trs. Has been working great, and I performed regular Mojave updates successfully.

    Well, it’s arguably one of the most famous islands. They could argue that MacOS Alcatraz is the most secure release ever. Until there is a big security vulnerability, and then they can say well even Alcatraz wasn’t escape-proof.

    macOS 10.15.4 Supplemental Update

    Heads up for those upgrading - using HD46000 iGPU and 4K displays - if you lose your 4K/hidpi resolutions, even after upgrading WhateverGreen/Lilu/AppleALC (and removing the installations under /L/E) you should make sure to run sudo kextcache -i / to rebuild kext caches.
