I have been getting this prompt frequently on my new Mac Mini with Big Sur. When I go to the Sec & Privacy System Pref - General, nothing there to allow what is being requested.I have uninstalled and reinstalled…same issue.
I don’t have a solution for you, but yup - that’s exactly what that message means. You’d need a Logitech kext / driver / whatever that was compiled for ARM.
In addition to asking here, I would also reach out to Logitech’s support and see what they have to say - sometimes support lead times suck, but in theory they should have the best info.
and it seems somebody asked about it, and the front-line people basically said “we’ll pass along your feedback”. You’d like to think they’d be working on it, but…
OMG…just got a response to my incompatibility report to Logi. “Try another computer…use a different USB port”…blah blah canned response to nothing I reported…geez
