Lost-Entrepreneur439 Posted June 28, 2023 Share Posted June 28, 2023 I'm helping someone test a kext for OpenCore that's supposed to bring GMA 4500MHD support with full QE/CI to Lion, they said they got the installer to boot on a Lenovo system however they couldn't install due to some issue with that computer, so they wanted me to test on my Pavilion dv6-1245dx, however trying to boot it, I get a panic on "IOAPIC: Version 0x20 Vectors 64:87)". It looks like an ACPI related panic? The 4500MHD kext is designed for OpenCore, so I am unable to use Clover or Chameleon. Screenshot and EFI are attached. Specs: HP Pavilion dv6-1245dx, Intel Pentium T4500 (this is a Penryn CPU, idk if it requires a spoof or not), 2x2GB DDR2 RAM (forgot the speed and brand), Intel GMA 4500MHD, 320GB 5400RPM Hitachi HDD, Windows Vista Home Premium SP2 64-bit (trying to install Mac OS X 10.7.5 Lion) yes i'm aware MacBook3,1 is the wrong SMBIOS for this hardware, it's currently set as that since I just modified my Latitude D630's EFI to work with this, I will fix that after I make this post, however I don't believe it's the cause of the panic.EFI.7z Link to comment Share on other sites More sharing options...
Lost-Entrepreneur439 Posted June 29, 2023 Author Share Posted June 29, 2023 It was on the r/hackintosh Discord server, they didn't really explain how they made the kext, they just pinged me asking if I had a system with a GMA 4500MHD, and they explained to me that he made this kext however due to issues with Lenovo or something he couldn't install Mac OS X so he wanted me to test. And people do still work with this legacy hardware for fun, it's the same reason that someone made an iOS 5 jailbreak this year and the same reason that there's a modern web browser for Windows XP, people just want to try to make it work as a fun project.

Administrators Hervé Posted June 29, 2023 Administrators Share Posted June 29, 2023 Typical Lion KP, it's a classic... On most Hackintosh systems, Lion required to revert AppleACPIPlatform kext to an older version from Snow Leopard. From memory, you'll be Ok with v1.3.6.

Lost-Entrepreneur439 Posted June 29, 2023 Author Share Posted June 29, 2023 I don't think thats the issue, as I tested with Snow Leopard before, and I got the same panic. Link to comment Share on other sites More sharing options...

Lost-Entrepreneur439 Posted June 30, 2023 Author Share Posted June 30, 2023 It turns out it was an issue with OpenCore, the LapicKernelPanic quirk was broken on Lion, I reported it on acidanthera's bugtracker, and it should be fixed in OpenCore 0.9.4, for now I'm using a dev build of 0.9.4 that has LapicKernelPanic fixed, and while after that I was able to get Mac OS X installed, the 4500MHD kext didn't work, which isn't surprising, if it was possible someone would've already done it by now. At least I now have a mostly working EFI for this system if someone else who is interested in legacy hackintoshing manages to get the 4500MHD working.
