darkghost568 Posted January 6, 2018 Share Posted January 6, 2018 Hi guys, currently I have El Capitan booting of an External WD HDD, and I'm trying to fresh install High Sierra on a Samsung T3 external SSD. However, when I try and boot into the High Sierra installer I get a permissions error! Here are the steps I used to make my High Sierra installer USB drive: --ran "sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Installer --applicationpath /Applications/Install\ macOS\ Sierra.app --no interaction" --ran a fresh install of Clover with "Install for UEFI booting only," "Install Clover in the ESP," only checked "CsmVideoDxe-64.efi" under "Drivers64UEFI," and "Install RC scripts on target volume" --Used a prebuilt EFI, and added the Haswell-E patches and modified the VoodooTSCSync.kext to 15 for my CPU (EFI.zip is >10MB so here's a drive link): https://drive.google.com/file/d/1f22p2F7kYaJgSRy659g8FBLSdD9xyjOH/view?usp=sharing --Used the BIOS settings found in the Archive.zip attached, and also did CodeRush's UEFI BIOS patch and flashed using the ASUS BIOS flashback --Used the files found here (http://www.insanelymac.com/forum/topic/330598-solution-does-printf-work-freeze-with-osxaptiov2/?p=2553095) to break through the "does printf work??" error Getting this error (first attached screenshot), which was followed by a permissions error (second attached screenshot), when I try and boot into the High Sierra installer. PLEASE can someone help? Thanks!

Smallersen Posted January 6, 2018 Share Posted January 6, 2018 I had similar problems at the beginning. There were 2 hardware related issues: CSM needs to be disabled in Bios, I had to patch my GPU. I also needed to patch my Asus Bios to make MSR 0xE2 writeable. 1 Link to comment https://www.insanelymac.com/forum/topic/331333-5960x-cant-boot-into-high-sierra-installer/#findComment-2563183 Share on other sites More sharing options...
darkghost568 Posted January 6, 2018 Author Share Posted January 6, 2018 I had similar problems at the beginning. There were 2 hardware related issues: CSM needs to be disabled in Bios, I had to patch my GPU. I also needed to patch my Asus Bios to make MSR 0xE2 writeable. Whoops, forgot a few things in the OP, updated now. Is the MRS 0xE2 writeable the CodeRush UEFI Patch? If so, I've done that. CSM is disabled now too. I also have 2x Titan X (Maxwell) in my rig, but for now I have them unplugged. I bought a GT710 off Amazon because I heard they were supported by High Sierra natively and didn't need any additional patches. I'm booting off the GT710 for now, and I'm still getting errors.
