Will not say it’s a definitive rule, and I did not try GDisk on my internal SSD to avoid any dangerous operation 😉 Well if you have BootCamp + MacOS and try to create a new partition, it will always fail (total number of partitions = 4 with EFI and Recovery) on my (now gone) iMac under Catalina, using APFS and FileVault.
#BOOTCAMP FOR MAC LINUX INSTALL#
I've tested other Linux distros, but I found the install process to be worse than the Ubuntu one (so can either refuse to install or strongly affect the MacOS boot). Which is sad, because the iMac is one of the only machine from Apple which is Ubuntu-friendly. So my reco as of now is not to target the iMac as a eGPU host under Ubuntu. I've tested the same methods on a PC, and they worked, so imho the problems were specifics to the iMac. Of course, I've tested the two TB3 ports, and also not using the X5 at the same time (Ubuntu on a USB3 SSD), but no luck either. I've tested all usual methods recommended on eGPU.io and dev oriented sites, and none worked.

The eGPU was detected and identified by Ubuntu, the card was visible from Ubuntu (PCI listing), but I haven't been able for the RTX to work with any driver (nouveau, graphics-ppa, proprietary from the NVidia website). So I had the opportunity to test for a few days a Razer Core X + NVidia RTX 2070 Super (NVidia branded) and the longer TB3 Belkin cable coming from Apple. I got an eGPU because needing to test CUDA performance for one project. I've used this set-up (triple-boot with Ubuntu on X5) for several weeks without any issue. I tested the Samsung X5, and not only the speed is sooooo much faster, but stability is solid as a rock. Using an external TB3 SSD is another story.

There are manual GRUB console commands to correct things at boot, but that's not user friendly. I didn't dig really deep, but it seems related to files getting corrupted when stopping the system (GRUB links to the kernel and boot files). But be careful though, as in my experience the external partition will fail on boot at a quite high frequency (every 45 days or so). rEFInd comes handy there, but I opted for the manual EFI files copy-paste-rename option, which is not safer, but avoids using any third party tool.Ībout external drives, USB3 SSD is really recommended for getting a snappy system. The installation process is not easier, because even when targeting the external drive, Ubuntu installer will modify the internal EFI partition. The only real solution there is to install Ubuntu on an external drive because of a limitation in the number of partitions on the internal drive. Now in my case, I wen the triple-boot way with Ubuntu + Bootcamp Windows + MacOS. People are suggesting to use rEFInd boot manager for dealing with these matters, but it's not mandatory. Before installing, you should backup files in the EFI (hidden) partition, since Ubuntu will add some and make Ubuntu boot priority. Basically, if you want double-boot between Ubuntu and MacOS on your internal drive, then you'll have to create a new partition for Ubuntu to be installed on.
There are many guides available, and I can link them if you want. It depends on the OS you want to have access to on boot. I'm pretty sure there could be some solutions to get the soundboard working, but I did not have the time to search and test them. In my case, I did not need audio, so no trouble. If you have an external USB DAC, then the DAC will in most cases work. The iMac itself is compatible "out of the box" with Ubuntu 16, 18 and 19 (and other Linux distros), except for the soundboard, which will not work at all.

I have used an iMac (Late 2017 i7 / Radeon 580 Pro / SSD) under Ubuntu for software development.īefore going to the eGPU topic, some feedback about using Ubuntu on the iMac.
