Hey Team,
I’m new hear and learned a lot from all the posts.
Today I want to share with you my experience with OBS and Mac during recording.

I use a MacBook Air 2017 ith Intel HD 6000 GPU. To the MacBook is connected a Sony A6400 via Elgato Camlink.

I tried many different coding settings (Apple hard and Software and X264). Nothing worked smooth and fluently in HD and 25-48 fps. The best experience I had with hardware encoding and 30fps in HD.

However, I have read a lot about the Sonnet RX 560 eGPU. I also read in this forum, that the eGPU won’t work with OBS. However, this is wrong.

Today I connected the eGPU with a Thunderbolt 3 to Thunderbolt 2 original Apple connector and a Thunderbolt 2 cable to my MacBook Air 2017.

The eGPU wasn’t recognized from the MacBook Air, because of the old Thunderbolt 2 connector.

However, I installed the Purge Wrangler Script.

After that my MacBook Air (with Thunderbolt 2) recognized the Sonnet RX 560 (with Thunderbolt 3)

I also enabled eGPU for OBS and tried recording HD 60fps with the Camlink / Sony A6400.

It was AMAZING. Super smooth! No breaks, no stops!

I also tested the GPU Benchmark with Geekbench.

Before: 3257 with Intel HD 6000 crap
After: 14225 with Sonnet RX 560

My crappy MacBook Air 2017 is now between the iMac Pro late 2017 (13459) and the iMac Pro late 2019 (14531).

Just remembering, Thunderbolt 2 is 50% slower than Thunderbolt 3, for those of you with a new Mac.

It should be much better than mine.
