G403Update
G403Update is a helper utility for Logitech's G403 gaming mouse. It manages firmware updates and driver installations for the G403, a popular wired and wireless gaming mouse featuring programmable buttons, adjustable DPI settings, and RGB lighting. The utility runs in the background to check for and apply updates from Logitech's servers. Like most hardware updater utilities, it is bundled with or installed alongside the primary Logitech G software suite rather than as a standalone product.

1 suggestionG403Update is a helper tool, not a standalone application — it is a sub-component of Logitech's G software ecosystem. To get it working natively on Apple Silicon, you do not update G403Update separately. Instead, visit Logitech's official support site and download the latest native version of Logitech G Hub (the primary app that manages all Logitech gaming peripherals on Mac). Installing or updating the main G Hub application automatically installs or updates all associated device-specific updater tools, including the G403 firmware updater, in their native forms. Once G Hub is running natively, any firmware updates for your G403 will be pulled through that interface. If you are not sure whether your installed copy is native or Intel, open G Hub, go to Preferences and check the "About" section — it will state the build architecture. Logitech has shipped native Apple Silicon builds of G Hub for several years, so updating should be straightforward.
