https://dortania.github.io/OpenCore-Install-Guide/ Followed it to the letter and EVERYTHING works first time with zero fuss. Just don't forget to move the EFI from the installer USB to the startup disc (I did and caused a little bit of a flap). I also would suggest using the debug...

OK, got this solved. Used Open Core to do a fresh install and (other than one user error mistake) got it installed first go. Happily running 10.15.7.

Hi All! Finally making the jump to Catalina from Mojave (after a software upgrade means I now need to upgrade the OS). Having tried every option possible with no luck (never ending dead ending on the 1689 issue), I decided to revert to my original idea of a completely fresh install to a new...

Hi Ed. Once again, thanks so much for your time on this. I sat down and went through what you kindly posted up. I spent time comparing the configs and updating/cleaning mine accordingly. I also updated (0r attempted to – more below) Clover, so should have the latest CC and updated CLOVERX64.efi...

Hey Ed. Thanks so much for this, I'll read through the guide again and start working things out; Mojave is running just fine apart from the sound. I did install Lilu and AppleALC via Kextbeast and they are kicking but clearly have missed something along the line... like those efi files! Could...

This one I do have an answer for :) Sound out via the headphones was working fine in High Sierra. This time around, after trying the various methods for getting sound to run, no dice. I am not even seeing a 'Internal Speakers' setting in the sound pref pane.

So have done everything but no dice. I'll have another crack but if nothing I might leave it – I only have the headphones connected, with no onboard speakers, and when I want sound, I stream it over WI-FI. I might end up grabbing a USB speaker for the machine.

Bit of an update, after a bit of fooling around, the machine boots into Mojave without the previous High Sierra drive attached, so a success. Still no onboard sound, though I have followed all the guides.

Yup! NoVPAJpeg.kext + Lilu.kext (installed using Kextbeast) worked a treat for me.

Hi Ed, Thanks for the reply! The machine's booting into the Mojave drive from Clover off the bat, just if I take out the old SSD, it does not. I've updated the SMBIOS via Clover to iMac 19.2, so that it matches the chipset and the new CLOVER folder from the mounted EFI is attached. I've not...

Hey All, I am hoping the collective brains trust might have an answer for this one... I updated from High Sierra to Mojave this week (being the up to date guy I am) and am having what i think is an odd boot issue. For the update I: Carbon Copy Cloned the running 10.13.x install (on Disc0...

Hey Folks! Been a long time, as my Hack has been flawless since building it and running updates. But the time has come to move to Big Sur - I have software that is no longer supporting or running on 10.13 :cry: Just picked up a MSI AMD Radeon RX 580 Armour in preparation for the swap but I...

@Stork Thanks so much for the reply. I went and did the lot from scratch again, you know, just to be sure. And everything's good, I am in High Sierra. Ran Multibeast, all good. Note on the plist file: out of the box, it was already set as per your instructions, so I left it alone this time...

Hi Stork, I have put together almost the exact same build as with but with the GTX 1070 card. Your guide has been a huge help but I seem to be running into two issues that I hope you might have some advice on, since you have the same build (and I have not been able to find a solution elsewhere)...
