Logitech MX Master 4

Owners keep the MX Master 4 for how deeply they can remap its buttons to fit specific workflows and games, even while they work around a rough patch of Mac software bugs.

What keeps coming up

Button customization draws clear praise: owners describe remapping the side and thumb buttons for everything from hero shooter abilities to file browsing shortcuts, and say the flexibility genuinely changes how they use the mouse day to day.

What keeps coming up against it

App usability is a clear concern. Owners describe Logi Options+ hanging on a loading screen, custom buttons and scroll direction resetting on their own, and basic functions breaking across multiple Macs at once.

Life with it

Once the initial setup is done, the parts owners keep coming back to are the button layout and the feel of the mouse itself. People build out per-app or per-game button schemes, some borrowed from years of habit on older mice, and the weight of the MX Master 4 gets called out as comfortable for long sessions.

What becomes routine, less happily, is checking in on the companion software. A macOS certificate problem surfaces repeatedly: the app gets stuck loading, custom buttons stop working, or scrolling inverts, and owners have had to learn where to find Logitech's patch page or apply a manual fix. Several say they've had to redo this more than once as the issue has resurfaced with later macOS or Options+ updates.

Reliability & repairs

The hardware side of the story is thin here: most of what owners report is about the software layer, not the mouse breaking down physically, and the mouse weight and button hardware get positive mentions without much detail on long-term wear.

Software reliability is where the real story is, and it is a mixed one. The recurring certificate and app-loading issues have official fixes from Logitech, and owners who find and apply the patch generally report it working, sometimes with a residual quirk like a slightly rough scroll wheel. But others describe the same bug reappearing after updates, and some have resorted to workarounds like temporarily changing their system clock to get the app to load. Customer support experiences split about evenly between people who got a working fix through Logitech and people who spent hours troubleshooting on their own with no resolution.

Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.

5 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
