    Can I install macOS on an external HDD and Linux on an internal HDD, without rEFInd andremoving EFI?

    Hello, I know if I remove the whole internal HDD and I install only Linux, it will not work. Therefore, I think of keeping EFI and Recovery Mode, so Linux partition would. I looked at the topic Can I replace MacOS with Ubuntu but keep my Windows partition?. But he did not say he removed or did...

    Downgrading from MacPro5,1 to MacPro4,1 after installing macOS High Sierra

    I'd like to try downgrading from a MacPro5,1 firmware to a MacPro4,1 (for testing). The machine was originally a MacPro4,1. I flashed it to a 5,1 and then installed macOS High Sierra (which updated the firmware in the process). I have both a Sapphire Radeon GTX 580 and an Nvidia GT 120...

    Mac Pro 4,1->5,1 RX Vega

    Do the RX Vega cards need to be flashed to work with the old Mac Pros? I've done a lot of research about Nvidia cards, but I don't really know how it works with the AMD cards. I've seen some stuff about editing kext files. If you do that does it work with the EFI, or would it need to be flashed...

    Heya! I saw gilles_polysoft made a miracle and gave our dusty machines to native NVMe abilities. I look at his twitter and he can edit Apple Efi with UEFITool. I am familiar with this kind of editing. I just ask myself to why didn't Apple release efi/bootrom files to public for corruption or...

    Hi, I just tried to move my whole main drive partition (It was just 1 "usable" that I was aware of, with Mac OSX High Sierra) to a new Samsung EVO 850 1TB Harddrive. I had to initialise it and convert it to "GPT"-format with my Windows 10 Desktop, because the installer tool from High Sierra...

    nVidia web driver users, hold off on the High Sierra Supplemental Update

    Just updated my flashed cMP 4,1 and I can't use my GTX 1080 Ti anymore. Usually, I can remote login just after an update to fix driver issues but I can't-do that either anymore. The only solution that has worked, so far, is switching back to the stock GTX 120. The firmware update and 'upgrade'...
