Two new eGPU solutions on macOS 10.13.4: pure EFI and hybrid
What is exactly the difference between Hybrid AMD and Clamshell? I'm asking because I usually close the MBP screen. Do I have to uninstall/reinstall or is it just an entry in some .plist to be edited?
That's interesting - almost identical setup to me, but mine doesn't work at all!
Just tried 1.0.4 on my system. Installed to a newly formatted flash drive using Hybrid (AMD dGPU), selected EFI boot as startup disk, then blank screen. It’s just sitting there, not showing anything - might this be an artefact of 10.13.6? I haven’t plugged in the eGPU - was waiting for the login screen for that.
@goalque, when booting, is there a way to force the efi boot entry instead of holding down alt and using it? refind doesn't work, gets stuck at booting os.
No, not at the moment. Maybe in the future. The default boot volume is always the one defined in config.plist's "DefaultVolume" key and the default disk image on Apple's boot manager is always what you have defined in "Startup Disk" (nvram variable). Clover's nvram setting didn't work well.
@chippy-mcchipset if you're not using "Pure EFI", you should always reinstall on each machine. automate-eGPU.kext needs to be created anyway in "Hybrid" mode. If both machines have AMD dGPU, the same config.plist might work.
Version 1.0.4 Hybrid AMD works fine on my 2017 15-inch TB RP560 MacBook Pro/Sonnet 550/GTX 1080 Ti, great work, thanks. What is exactly the difference between Hybrid AMD and Clamshell?

Nice! 10.13.4, 10.13.5 or 10.13.6? With Hybrid AMD/iGPU mode you can use both the internal and eGPU screens, the clamshell mode disables your internal screen. Switching between Clamshell mode and AMD dGPU/iGPU on-the-fly isn't yet supported, you can only use one at a time, and if want to change mode, uninstall/reinstall.
Thanks. If it's 13-inch that should be Hybrid iGPU right?
Yes, 13" MBPs are iGPU only and the closed-clamshell mode is meant for AMD dGPU MBPs for now.
@goalque, I may have made a discovery with the hybrid mode. when my mac was off, the egpu was plugged in. I booted it, selected the efi boot disk and the egpu was instantly recognized since it made an animation to recognize my "second monitor" during the apple boot screen. I checked this and it said that the display was recognized, and therefore the gpu is recognized. This experience did not need the egpu hotplugged after login, the computer just recognized it all by itself
@kingbri That's how it's been working before, and may still work with v1.0.4 but hot plugging is the recommended way in hybrid mode.
Which mode to choose if I have a iMac (Retina 5K, 27-inch, Late 2014)?
No one has tested this with the 5K iMac, I would try "Hybrid (AMD dGPU)". Hot plug after logged in.
