Anyone successfully install El Capitan UEFI? Steps you used? I attempted, 3 times, re-created USB three times too - seemed to work ok but no audio and most USB ports didn't work. I can now no longer boot the 8500 via UEFI with a UEFI Unibeast created USB. It'll boot up then no sign(where it worked a few times before, I changed nothing on the system...)
Legacy worked though, all USB ports work, no audio - ordered a USB audio adapter to solve. Would love to use UEFI install though.
Anyone do a fresh install of El Capitan UEFI on their 8500 yet?
I have successfully installed El Capitan legacy mode ok. Procedure that worked is below.
Create unibeast[Legacy]
Boot from USB, install El Capitan
Setup El Capitan
Run Multibeast:
Quick Start > Legacy Boot Mode
Drivers > Audio > Realtek ALCxx > ALC887/888b [audio does NOT work - I have two line out options to choose from but no audio]
Drivers > Disk > 3rd Party SATA
Drivers > Misc > Fake SMC v6.18.1394
Bootloaders > Clover v2.3k r3320 Legacy Boot Mode
Cutomize > System Definitions > Mac Pro > Mac Pro 3,1
AFTER Multibeast is run and a restart all USB ports work. Audio still doesn't work and I redid everything and tried legacy option for ALC887/888b and that was worse than normal option(USB audio adapter ordered).
Otherwise system appears to work fine, I have NOT tested sleep it has yet to ever work for me on any hackintosh.
So I never sleep the computer, and only sleep the display.
Looking forward to anyone with correct procedure for UEFI install to work on the XPS 8500 - and audio.
Thanks to everyone here at Tonymac - lots of searching/lurking over the years - hope this post helps someone.
I did NOT inject ATI or anything for the video card, tested with Hearthstone, seems to be working, video does glitch a bit right after Apple logo progress bar finishes up at boot, and if I switch display input away from DVI to VGA(VGA hooked up to a PC) I get a neat high resolution colored snow background for less than a second. DVI monitor hooked up, 2nd DP monitor both working great.
Dell XPS 8500 i7 3770, ATI 6850, no other cards installed, no wifi, no bluetooth.
