Sorry if this is a known issue - I had a look and couldnt find anything that fits.

I keep receiving the "Failed to find multiple gpus" error on startup and gSwitch seems unable to allocate most applications to the internal gpu (if any). I basically want to keep osx apps using the integrated graphics so I can disconnect my eGpu without needing to restart everything.

I have a Macbook 2019 13" (Catalina 10.15.6) connected to a Razer Core X Chroma + Radeon™ RX 580 GAMING 8G. The first time I installed gSwitch I think it was working fine - but a few days later it suddenly started reporting errors? I can't quite figure out how to fix it (or if I can)?

Thanks for the reporting this, unfortunately I don't think this is something I can solve. gSwitch was never designed with eGPU support in mind, and I don't have an eGPU so it would be very hard for me to test. Also, I'm assuming this is something on the OS level that I can't fix, given the 'No matching drivers found.' error that is being reported.

I will leave the issue open if anyone wants to tackle it.
