Knob drama turns up to 11
Griffin PowerMate driver for modern macOS
A forgotten desk knob is back, and the internet is raiding attics to find theirs
TLDR: A new macOS driver has revived the old Griffin PowerMate, a simple twist-and-press desktop knob that had stopped being useful on modern Macs. The big reaction wasn't nerdy specs — it was people joking about digging through drawers, attics, and even questioning whether they still need a Mac to use it.
A tiny metal knob from the early 2000s has somehow become the main character again. The Griffin PowerMate — a little desktop dial you twist and press — now has a modern macOS driver, which means this retro gadget can once again scroll pages, click like a mouse, and even glow dramatically while you use it. In plain English: someone brought an old favorite back from the dead, and the comment section immediately turned into a full-blown USB drawer treasure hunt.
The loudest reaction was pure nostalgia-fueled chaos. One person basically announced, "I have one... now I just need to find it," while another blamed the post for sending them to clean out the attic. That became the running joke: not whether the driver works, but whether anyone can actually locate the ancient knob in the first place. The vibe was equal parts excitement and mild domestic inconvenience.
Then came the hot takes. One commenter dropped the driest burn in the thread: they have the gadget, but now need a reason to use the Mac itself. Ouch. Meanwhile, another casually one-upped the whole story with: lol, they already wrote a driver for the Bluetooth version months ago. So yes, even in a wholesome retro-hardware revival, the comments found a way to add a little "my side project walked so this could run" energy.
And for everyone who never owned one, there was envy too: people calling it cool and wishing they'd had one. So the real headline isn't just that the knob is back — it's that the internet is suddenly united by one question: where did I put that thing?
