evy0311 Posted September 25, 2019 Share Posted September 25, 2019 I have a Latitude 5591 that I am wanting to install macOS on. To start, what is the highest version supported? If I can get mojave going that would be sweet. It is the i7-8850H processor and 620 UHD graphics. I am not new to Hackintoshing but this laptop is giving me a lot of headaches so i figured i'd look here for help. Does someone have a pre-made config.plist and other files I'd need to be able to boot? Thanks so much@ Link to comment Share on other sites More sharing options...
Administrators Hervé Posted September 25, 2019 Administrators Share Posted September 25, 2019 This is a Coffee Lake laptop and, on paper, is therefore compatible with all recent macOS versions and forthcoming Catalina. You may look at our Latitude 7490 guide for guidance as your model probably bears some similarities. Link to comment Share on other sites More sharing options...
evy0311 Posted September 25, 2019 Author Share Posted September 25, 2019 Awesome, thanks so much. I started following the guide. It wouldn't boot with the same ACPI patches so I removed them, but when in the installer, my screen has no backlight, and then it flashes for 1 second, and then goes away for 10 seconds, and then flashes again. Any way to fix that or will I need to patch it? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 25, 2019 Moderators Share Posted September 25, 2019 Just leave out the DSDT.aml and try again. Boot with verbose + debug 0x100 mode by pressing the spacebar and select them Link to comment Share on other sites More sharing options...
evy0311 Posted September 25, 2019 Author Share Posted September 25, 2019 Jake, Will do. I will work on this after classes today and report back to you. I have patched the ACPI before on my Thinkpad laptop so I am not fully new to it but will likely need a bit of help/guidance. Link to comment Share on other sites More sharing options...
evy0311 Posted September 25, 2019 Author Share Posted September 25, 2019 So after doing this, I left the file out you mentioned but it is still doing the screen thing. Except rather than starting the backlight flash at the installer, it is now starting it when i am at the verbose screen with text coming out. Ideas? It still boots into the installer, but the flashing starts during the verbose output. I have attached here my ACPI dump from inside of clover pressing F4, not sure if this will help but here it is. Thanks so much!! origin.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 25, 2019 Moderators Share Posted September 25, 2019 At Clover gui, press O to get to Options. Go down to Graphics Injector and select it Select both FakeID and platform-id and change them to 0x12345678 Enable verbose and debug 0x100 mode Continue booting Link to comment Share on other sites More sharing options...
evy0311 Posted September 25, 2019 Author Share Posted September 25, 2019 Jake, It still seems to be doing it, despite what you told me to do. Anything else I can try? Like i said this is only when im in the installer/verbose mode booting up, everywhere else the backlight works. I am using the files linked in the tutorial for the 7490 from this tutorial here: Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 25, 2019 Moderators Share Posted September 25, 2019 try booting with boot arg -igfxvesa Check the BIOS, make sure you have UEFI /AHCI enabled. Disable Legacy Option ROMs/ Secure Boot Link to comment Share on other sites More sharing options...
evy0311 Posted September 25, 2019 Author Share Posted September 25, 2019 Hi! Same thing unfortunately, and I made sure my BIOS settings match the ones you mentioned. On boot up, the screen seems to turn the backlight off right around the time when multiple lines come through about an ACPI error. Also errors coming through about no sensor found for system fan, etc. I removed the DSDT file like you mentioned. Is there something else i should try?
