I do abhor the option to "try another distro" but my #iMAC adventure seems opposed to #Debian13 Wayland, and, oddly, Debian doesn't offer any obvious alternative. The iMac only has VA-API support for X11, and the bridge package solved the Firefox video lag, but my mouse cursor still vanishes, only restored by a reboot.
And today a further symptom suggesting a different video driver is needed: running the default Chromium, the screen goes into a psychedelic dance for almost a minute before a stable screen appears. Oddly, unlike most Linux distros, I can't find the option to search for alt drivers.
I miss Xorg already.

not terribly encouraging, this #iMac was purchased off Marketplace with Mint installed, so no one knows the boot menu incantation, but I did try a different USB kbd and THIS time holding Alt and Power brings me to an EFI Boot page, so this is interesting …
and possibly absolves the power button mechanics? Perhaps some other Amazon Basics key command? It need only work once!

#Debian13 loaded #Gnome into the #iMac just fine using the SD reader, set it up, loaded kdenlive etc to later test, created my users, but now a new problem I've not encountered before:
the mouse cursor spontaneously vanishes. I still have mouse control, things highlight on hover, but the pointer icon disappears. Switching windows, switching to tty1 and back, not even changing users! On reboot, not touching physical wires, the mouse has a cursor again.🤔
