Battery in the menu bar
Live percentage with a bolt while charging, a learned time-until-empty estimate built from your own mouse's discharge history, and a warning once it drops below 15%. More on battery →
Unofficial project. MacRazer is not affiliated with, authorized by, or endorsed by Razer Inc. It's a community app that reimplements the parts of the protocol documented by OpenRazer.
Where each one fits
Both are worth having. If Synapse for Mac supports your device and you want macros and cloud profiles, use it. This page is for the case it doesn't cover.
| Razer Synapse for Mac | MacRazer | |
|---|---|---|
| Device coverage | Razer's published supported list | Any mouse speaking the protocol; verified on the Cobra family and Atheris |
| Hardware | Apple Silicon only | Apple Silicon, macOS 14+ |
| Account | Sign-in for cloud profiles | None |
| Source | Closed | GPL-2.0, auditable |
| Macros | Yes | No, two side buttons remap only |
| Battery history | Current level | Discharge curve, learned time-remaining, past cycles |
What MacRazer actually does
DPI and polling rate
Set DPI, edit the stage table your mouse's own DPI button cycles, and switch polling rate between 125/500/1000 Hz. Written to onboard memory, so it survives quitting the app.
RGB without Chroma
Static colour, spectrum cycle, wave, or off, plus brightness. No Chroma runtime, no background service.
Side-button remapping
Map the two side buttons to keys or shortcuts. It works software-side, so it needs Accessibility permission. The other buttons are handled on the mouse itself and macOS never sees them.
Common questions
Does Razer Synapse work on Mac?
Yes. Razer ships Synapse for Mac, on Apple Silicon only, with a published supported-device list. Check that list first. If your mouse is on it and you want macros, use Synapse.
My mouse isn't on Razer's list. Now what?
That gap is why MacRazer exists. The Cobra HyperSpeed and Atheris weren't covered. The protocol is largely shared across models, so an unsupported-by-Synapse mouse usually still answers. See supported mice for what's actually been verified on hardware.
Do I need a kernel extension or a driver?
No. macOS already enumerates the mouse as a HID device; MacRazer sends feature reports to it. You do have to grant Input Monitoring, because macOS gates HID access behind it.
Will it work over Bluetooth?
No, and no app can. Razer only exposes the control protocol over USB, so use the 2.4 GHz dongle or a USB-C cable. Over Bluetooth the mouse is just a pointer.
