Thunderbolt 3 eGPU with a 2015 Thunderbolt 2 MacBook pro - will it work?
With no hardware updates at WWDC this week i'm left waiting until September to see whether Apple will make enough improvements to the MacBook pro before jumping to a Windows ultrabook. Until then i was thinking i could still get an Thunderbolt 3 eGPU and use it with my 2015 MacBook pro through the Thunderbolt 2 port as all i'd need is the right cable, but is it that simple? Are there any software restrictions for this setup? If not then would be I be able to do some light 1080p gaming such as Total War series and Fortnite?
macOS 10.3.4 and higher automatically block eGPU use on TB1/2 Macs, but the wonderful folks here have devised ways around this:
2016 15" MacBook Pro - 2.7GHz Core i7, Radeon Pro 460 4GB, 1TB SSD
Sonnet Breakaway Box 350 with Radeon RX 580 8GB
What @detunedradios said. But also note that it does work fine in Windows (I'm using a 2015 MBP myself with a Razer Core X and an RX580).
I was right there with you being disappointed about WWDC being only software announcements! 🙁 Personally I'd just run Windows right on the MBP versus replacing with a PC-only machine but good luck!
death to self
I had a success with setting up Sonnet breakaway box with RX580 on bootcamp with 10.13.5 (Macbook pro 13" retina mid 2015). However, when I attempted to repeat same thing with Macbook pro 15" retina mid 2014 - it was utterly difficult and I am still yet to figure out how to make that thing work ( https://egpu.io/forums/pc-setup/yet-another-issue-with-sonnet-550w-rx580-bootcamp/ describes my current issue). So, I guess, proceed at your own risk, in my experience this setup is super flaky, my gaming friends look at me like I am a freak by running such a weird setup for gaming system. Separate PC machine would definitely be more of a breeze setup-wise.
