Razer Synapse 4 is the current Windows device-control platform, with a separate Mac Preview for supported Apple silicon systems. Use the checker below before opening the official download.
Choose your operating system and goal. Add a device name or RZ model number for an extra compatibility reminder.
The result includes platform requirements, the reason for the recommendation, and a verified Razer source link when one is available.
| Windows | Windows 11 x86-64 or Windows 10 |
|---|---|
| Mac | macOS 15 Sequoia or later on Apple silicon; Preview status |
| Synapse 3 devices | Razer states backwards compatibility for devices on its current Synapse 4 list |
| Browser option | Synapse Web for selected devices with current firmware |
| Published version/file size | Not stated in the visible Synapse 4 product facts; this guide does not invent either value |
The Windows and Mac buttons lead to different installers. Windows users should confirm Windows 11 64-bit or Windows 10 and then check the exact device on Razer's supported-device list. Mac users need macOS 15 or later, Apple silicon and a device on the separate Mac list.
A product-family name is not sufficient evidence. DeathAdder, BlackWidow, Basilisk and Viper families span many generations. Match the exact name or RZ number before starting the Razer Synapse 4 download.
Razer says Synapse 4 includes a profile migration tool that can detect Synapse 3 profiles, macros and Chroma effects. You can migrate available profiles together or select only the profiles you want.
The old Synapse 3 product URL now redirects to the Synapse 4 page. That makes migration guidance more useful than distributing an unverified Synapse 3 installer. Keep a record of important mappings and confirm migrated macros after the upgrade.
Downloading the app does not guarantee that every connected Razer device is supported. Device compatibility, operating-system support and firmware state are separate checks.
Razer reports performance improvements compared with Synapse 3, but actual performance varies by hardware, modules and settings. This independent guide does not reproduce a universal speed claim as a guarantee.
A current installer can also change after this page is published. That is why the button points to Razer's maintained short link instead of a copied file URL. Recheck the product page when the operating system, device firmware or installer behavior changes.
Use this Razer Synapse 4 download checklist before opening either platform installer. The same product name can cover several hardware generations, and Windows support does not prove Mac support. A reliable decision combines the current operating system, processor architecture, exact RZ model number, official compatibility entry and intended migration path. Record those details first so a failed setup can be traced to one condition instead of repeated with an unknown mirror.
For Windows, verify Windows 11 x86-64 or Windows 10 and install the current Windows branch. For Mac, verify macOS 15 or later on Apple silicon and remember that the build is still labeled Preview. Do not move a Windows installer to a Mac or use the historical Synapse 2 Mac package on a current Apple silicon system. The Razer Synapse 4 download must match the computer that will actually run it.
Read the label on the mouse, keyboard, headset or accessory and search the complete model. Family labels such as DeathAdder or BlackWidow are not precise enough because older and newer generations may use different software paths. Confirm the device on the relevant Windows or Mac list before continuing. If the exact identifier is absent, stop and use Razer Support rather than assuming a similarly named product proves compatibility.
When replacing Synapse 3, note important sensitivity stages, button assignments, macros, game profiles and Chroma effects. Install only the modules you need, run the built-in migration workflow and test each transferred setting before removing old data. A completed import confirms that data moved; it does not confirm every macro, device assignment or lighting effect behaves exactly as it did in the former application.
Open the maintained Razer link, allow the installer and device services to finish, then restart when requested. Confirm that Synapse opens, identifies the exact hardware and exposes the controls you expected. If recognition fails, preserve the installer log, recheck the support list and use the troubleshooting guide. Do not solve a device-list mismatch by downloading a file labeled as a newer, portable or offline edition from a third party.
This Razer Synapse 4 download checklist separates download availability from actual compatibility. A valid result requires the supported operating system, supported processor where applicable, exact listed device, current first-party installer and a successful post-install recognition test. If one condition is missing, return to the platform or supported-device guide before retrying. That sequence is slower than guessing from a filename, but it protects profiles and makes any support request much easier to diagnose.
Razer presents Synapse 4 as its device-control software and provides direct Windows and Mac download links. This guide does not charge for or host the installer.
The former Synapse 3 product URL currently redirects to Synapse 4, and Razer promotes profile migration plus backwards compatibility for devices on its Synapse 4 list.
Yes. Razer lists Windows 11 x86-64. Confirm that Windows is 64-bit and that the exact Razer device is supported.
The visible official product page checked for this guide did not publish a simple current version number or file size, so we do not invent one. The download button opens Razer's maintained source.
