A wireless Razer mouse is harder to check on a Mac than most. Razer Synapse for Mac is a preview that supports few devices, and macOS does not list a mouse that connects through a USB dongle. Here is each place to look, and how to get the level in the menu bar.
Razer Synapse for Mac
Razer released Synapse for Mac as a preview in May 2025. Razer says it supports only Macs with Apple silicon that run macOS 15 Sequoia or later.
In 2026 it is still a preview. It works with a short list of recent devices, for example the Viper V4 Pro and the Pro Click mice, and Razer adds devices over time. Many older devices are not on the list.
- Open Razer’s page for Synapse for Mac and read the list of supported devices.
- If your device is on the list, install Synapse.
- Open the page of your device in Synapse.
If your device is not on the list, Synapse does not help you.
The Bluetooth settings
Some Razer mice and keyboards have a Bluetooth mode next to the 2.4 GHz mode. If yours is paired over Bluetooth:
- Open the Apple menu and choose System Settings.
- Click Bluetooth.
- Look under the name of the device.
A level is there only if the device reports one to macOS. See Bluetooth battery level not showing on a Mac for the causes when it is missing.
Razer mouse battery not showing on a Mac
On its 2.4 GHz dongle, a Razer mouse is a USB device to the Mac. The Bluetooth menu, the Bluetooth settings and the Batteries widget list Bluetooth devices. The mouse is not in any of them, and no setting in macOS adds it.
A Logitech mouse on a Bolt or Unifying receiver has the same limit. See how to check a Logitech mouse battery on a Mac.
Free tools
Two free projects read the battery of some Razer mice on a Mac.
- MacRazer shows the percentage in the menu bar, on the dongle or on a USB-C cable. It needs macOS 14 or later, Apple silicon and the Input Monitoring permission. Its site lists five mice as tested.
- razermon shows the battery in the menu bar. Its author tested it on one mouse, the Viper Ultimate, and says it is not mature.
Razer macOS, a third project, controls lighting. Its description does not list a battery level.
Keep the Razer battery in the menu bar
BatteryBud is a battery monitor for Mac. From version 1.2.0 it shows wireless Razer mice and keyboards, on their dongle or on their cable, with history and alerts like any other device.
macOS needs one permission for this.
- Connect the Razer device.
- Open Settings in BatteryBud, then Devices. An Allow… button is there when BatteryBud finds a Razer device.
- Click Allow… and turn on Input Monitoring for BatteryBud.
Razer devices report their battery through the same USB interface that sends key presses and clicks. macOS protects that interface, so it asks for Input Monitoring. BatteryBud uses the permission to read the battery level.
After that you can pin the mouse to the menu bar with its percentage, and set a low battery alert at the level you want. If your device is missing, the same page has a button that makes a short report of what is connected, which you can send to us.
