### Details
- 2018 Intel Mac Mini, Mac OS Sequoia 15.7.7
- Trying to add my Mac K750 Wireless Solar Keyboard which using a Unifying receiver.
- When I clicked add device, it said Device paired, and for a short time, I will see (strangely) 3 different keyboards show up, K750, MK700, and K750 again. However after that it will go back to showing no device connected just randomly. Trying to restart the app will sometimes let me do it again, or it will just hang at searching for devices.
- When it was active and I was able to click on it and see Device Details, I couldn't configure anything.

Start by reproducing the K750 Wireless Solar Keyboard issue on the stated Intel Mac Mini and Unifying receiver setup, then run `openlogi list` and `openlogi diag features` as requested in the report. Done means the paired device remains visible instead of disappearing or leaving the app searching, and its device details can be configured.
