Millions of Logitech mice bricked due to expired developer certificate

Notably, new MX Master 3S and MX Master 4 models require the Options+ app to function properly. Additionally, the gaming app G HUB also stopped working on Macs. Logitech has promised to release a fix "soon."
This incident highlights the critical importance of timely developer certificate renewals, as a missed renewal left thousands of users’ peripherals unusable. The company is expected to issue an update shortly to restore device functionality.
