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...

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...

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. Recently my son accidentally clicked upgrade to Catalina in the system preferences page, and the machine now boots to a blank screen...

MacOS Joshua Tree. Maybe U2 can release a new song to coincide with the release and feature it in Music app.

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.

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.

sudo kextcache -i / did the trick... 4K back to normal

Thanks — yes that’s why I removed them from /L/E and installed the latest into kexts/Other but seems like it’s not loading.

Post #69 I upgraded to 10.15.4 Supplemental and lost all HiDPI 4K settings again, and cannot get them back. I upgraded Lilu, WhateverGreen, AppleALC in the EFI/Clover/kexts/Other directory, and removed them from /L/E and didn't help. I then tried installing the latest of all 3 back to /L/E and...

I upgraded and lost all HiDPI settings again, and cannot get them back. I upgraded Lilu, WhateverGreen, AppleALC in the EFI/Clover/kexts/Other directory, and removed them from /L/E and didn't help. I then tried installing the latest of all 3 back to /L/E and fixed permissions using KextUtility...

I updated Catalina to 10.15.4 and it went smoothly but I lost my 4K HiDPI resolutions with my LG 4K monitors (both DP connections using HD4600 onboard graphics). I had uninstalled all kexts from /Library/Extensions https://www.tonymacx86.com/threads/macos-10-15-4-update.292646/post-2097067...

Updated Clover, Whatevergreen, Lilu and AppleALC as recommended. Moved kexts to clover and removed from /Library/Extensions Unfortunately, all HiDPI/4K resolutions disappeared after I did this, with HD4600 igpu. I re-installed Lilu and Whatevergreen back to /Library/Extensions and that fixed...

I had set my system to MacMini6,2 and that won’t work with egpu. So set it to a system that such as iMac as I mentioned. That worked immediately for me.
