Hello hello!! I was just following the Keybow OS tutorial and wanted to share a quick tip.
The tutorial currently suggests the SD Association’s SD Memory Card Formatter. But, on macOS, that app doesn’t actually format cards in FAT32 (it often defaults to ExFAT for larger cards). And the Keybow doesn’t light up.
But, using the “Erase” (Format as FAT32) function in the Raspberry Pi Imager worked! It might be a handy alternative to mention in the guide to save others a bit of troubleshooting :)
Thanks for the awesome hardware!
