I have a hackintosh that I built and then re-built so I could dual boot with a linux distribution so I could (eventually) shift platforms. I ran Manjaro at first, because I liked the idea of a rolling distribution. But an additional wrinkle was that my audio interface is firewire-based, and I had trouble configuring the system with ffado. So I tried vanilla Ubuntu that I optimized for audio. I got everything working, but couldn't get JACK to work any better than 44.1KHz 256 sample frame buffer and 2 periods. So, I thought I'd try a music specific distro, KXStudio is on a break, so I went with AVLinux. I have my reservations with both of these. Not for their fine work, but for the inherent insecurity of dealing with single maintainer distros.
This has been a total nightmare. My particular setup, that is, a dual booted hackintosh, means that I have to figure out how to install AVLinux boot loader files in my existing EFI partition. The Systemback install makes this difficult. I have tried several approaches, even removing the MacOS drive and just doing a straight AVLinux install. But whenever I get to the part of the install (p. 38 of the manual!) where I'm supposed to see a "hint" to set the mount point as /boot/efi, and the GRUB dropdown is supposed to be greyed out. . . . I get none of this, no hint, no EFI in the GRUB dropdown. Nada.
So I tried to join the AVL forum for help. Two hours later, I gave up. I couldn't even register. It kept erroring out on me, or kept blithely telling me that I had to prove I wasn't a bot. And there's no way to contact the webmaster, or anyone for that matter, to get clarification.
AVLinux may be the bees knees, but the difficulty of dealing with the install and the support forum has completely soured me on the thing.
I am extraordinarily frustrated at this point. So, next best? I'd be happy to install a distro that will let me install the uefi boot files to my existing EFI partition, has a realtime kernel, and that I can add the KXStudio repositories to. Can anyone recommend something? Til then, I'm back on my Hackintosh. Thanks.
