In the event you use Logitech gear on a macOS machine—maybe you bought a model new MX Grasp 4 over the vacations—and noticed it stopped working, that is as a result of Logitech forgot to replace its dev certificates. Whoopsie.
As reported by The Verge, the Logitech Subreddit noticed Mac customers complaining that their app wasn’t working, and one remark confirmed that Logitech’s developer certificates expired on January 6, 2026. Renewed 5 years beforehand on January 5, 2021, Logitech should keep vigilant at first of 2031 to catch the identical mistake.
Annoyingly, the app is not going to mechanically replace, because the expired certificates problem additionally hit the updater. Meaning the one option to remedy the difficulty proper now could be to obtain the brand new model manually. Logitech does say to not uninstall the app, as you possibly can lose progress that approach, and it is pointless to take action.
Although the repair is now out within the wild, customers over on Reddit have used the momentary outage to complain extra broadly about Logitech’s software program. One person, with virtually 300 upvotes, says, “What occurred prior to now 24 hours was unacceptable. I feel you understand that. I additionally suppose you understand by now that you simply made hundreds of individuals waste tens of hundreds of hours (and possibly hundreds of thousands in misplaced time) making an attempt to determine what’s damaged this time.”
They go on to state that the Logitech app is commonly an issue for them, and so they took the outage as a standard a part of utilizing the app. Although I would not go fairly as far, and I feel the app has gotten higher over the past yr, I’ve additionally run into my fair proportion of issues with it. This has gone from boot loops to needing to reinstall your entire app. One focus of this criticism is the “AI nonsense“, and one other was a person caught losing PC sources on the app as a result of updater going incorrect.
Although the issue is now fastened, it seems to have signalled a broader annoyance at Logitech’s software program, one thing that the corporate is probably going effectively conscious of.
