Hi Erwin and zipb,
1) I reloaded 10.11.5 and still have issues with the additional entries. When I rename /EFI/BOOT/BOOTX64.EFI to /EFI/BOOT/BOOTX64.EFI.OLD the issue of additional entries stops but I can no longer boot into my installation (even using F12 for UEFI entry) without my thumb drive. If I rename it back, no problems.
NOTE: When I attempt to boot, even unsuccessfully, the UEFI BIOS creates another entry. Curious...
2) When my monitor sleeps I have to hit power button, rather than move mouse or hit space bar, as in windows. Not sure if this is an issue or feature.
Very carefully follow Erwin steps(I didn't, but I understand his 'method'). Clean up your boot mess often. Save your BIOS settings. At some point, after several tries, it suddenly worked for me. Of course, you need a proper EFI partition with a boot loader on the disk you're trying to boot from.
Sleep doesn't work for me. Well, maybe for a couple of seconds. Didn't work on my old system either. Not very important.
No proper shutdown is quite irritating though, as my CCC script with automatic shutdown doesn't work anymore.
Built in audio out works, AFAIK. Not important at all, as I have a firewire device for proper audio. There were 2 things I had to select in Multibeast, one first, then the other, which I did, and it worked. I wasn't expecting much, but the quality is not bad at all...
