In a modern MacBook there are usually two GPUs
Integrated and Discrete, with Discrete being much more powerful.
Usually when a macOS app is utilising the discrete GPU I receive a notification to say the GPU is being used.
I don't see this notification with Hashcat, yet I see that hashcat
looks like it's using both:
Code:
OpenCL Platform #1: Apple
=========================
* Device #1: Intel(R) Core(TM) i7-8850H CPU @ 2.60GHz, skipped.
* Device #2: Intel(R) UHD Graphics 630, 384/1536 MB allocatable, 24MCU
* Device #3: AMD Radeon Pro 560X Compute Engine, 1024/4096 MB allocatable, 16MCU
Do I have to directly enable the discrete GPU to use it?

can you post a hashcat status output?

Seems like it's using both, however on the macOS dashboard (where it would usually say GPU enabled, as it would when playing games or something that explicitly uses the GPU), it doesn't indicate that the GPU is actively engaged...

Looks like a bug in the macOS dashboard then. Probably not accounting for OpenCL usage. Speed also seems ok.

Cool thanks.
