2 AIs tried to help me: 1 succeeded.

I'll compress two+ hours of repeated rage-inducing TechnoDolt©®™FAILS into the following account.

1. I bought a Das Keyboard 4 with super-loud clicky key press noises because I wanted a blast from the past: I had a Das keyboard 20 or so years ago but tired of the effort required to type along with the noise, and since then I've used silent Apple keyboards.

2. Only when it didn't work after connecting it to my MacBook Pro and asking Perplexity Pro why not did I learn there is a specific version made for Mac and a different version for Windows/PC. I had no idea that was the case. Investigation revealed mine is a Windows/PC version. Much gnashing of teeth and pulling of hair and screaming ensued.

3. Once I calmed down, I asked Perplexity if I could use my version with my MacBook: it replied "Yes," and added that I'd need to remap the keyboard. OMG. That's so far above my TechnoDolt©®™ pay grade I'd have to wear shades to have any clue. I did realize this was not as simple as switching from Google Maps to Apple Maps but rather required some degree of computer savvy.

4. Nevertheless, I persisted. After around two hours of multiple FAILS/dead ends, I gave up.

5. But I was REALLY annoyed!

6. $200 for what?

7. Fortunately for me, the next thing I'd intended to do was go running; the two+ hours of dead ends meant it was now 10° hotter and the sun was beating down instead of the shady run that would've happened two hours earlier. By persisting with the keyboard follies, I could delay my run, which I dislike intensely, even more!

8. I took a flutter on Google Search's recently built-in Gemini AI and asked it the same thing I did with Perplexity.

9. Pictured up top, where Gemini triumphed almost immediately after I asked for help because my Das keyboard wasn't showing up on my MacBook: Check Your Adapter

10. I was using a generic USB-C to USB adapter set-up (below, top) up to that moment. I dug around in my cable drawer and darned if I didn't have the recommended Apple USB-C to USB-A adapter (below, bottom).

11. I replaced the generic adapter with the Apple version and OMG onscreen instructions appeared in the form of the MacBook's "Keyboard Assistant" that guided me to an easy-peasy setup that took under a minute — and my Das keyboard worked!!!

Bottom line: don't waste your money ($17/month) on Perplexity Pro — go with the freebie from Google, which is right there on the main search page and doesn't require you to open a separate app.
