Operating system and hardware requirements

Written for Synergy 3 (v3.7.2) and Synergy 1 (v1.21.4), checked 4 October 2026.

We support every operating system for as long as its vendor supports it. For business and enterprise customers, that includes the vendor's paid extended support.

There are also some hardware requirements for Synergy 1 and Synergy 3:

1. An Ethernet or Wi-Fi network connection where both computers can see each other.
2. Each computer must have its own screen or screens (there is no video sharing feature).

For business and enterprise customers, we support every operating system its vendor still supports, paid extended support included; see Extended support for business customers, below.

For personal, non-commercial customers, we support every operating system in its vendor's standard support, long-term support included. If the current version doesn't run on yours, you can ask us to build it: Contacting our support team

Using an older system? See Legacy operating systems, below.

Synergy 1 and Synergy 3 support the same macOS releases, listed next. The Windows and Linux releases each supports are in its own section, below.

macOS

• macOS 27 Golden Gate
• macOS 26 Tahoe
• macOS 15 Sequoia

Synergy 1 and Synergy 3 run on Apple silicon (M-series) and Intel Macs. macOS 27 runs on Apple silicon only, so on an Intel Mac the latest supported version is macOS 26.

Which Linux package to download

On the Synergy download page, pick the section named after your Linux distribution, then the release you run. If your distribution isn't listed, or you're not sure, use Other Linux, which is the Flatpak and works on most distributions.

The package format follows the distribution: .deb for Ubuntu, Debian, Linux Mint, Pop!_OS and Raspberry Pi OS, .rpm for Fedora, Red Hat Enterprise Linux, Rocky Linux, AlmaLinux and openSUSE, and .pkg.tar.zst for Arch Linux, Manjaro and CachyOS.

Linux Mint 22 and Pop!_OS 24.04 have sections of their own on the download page, offering the Ubuntu 24.04 package they're built on. The Ubuntu 26.04 package is built for newer libraries than theirs, so it doesn't run on them. Linux Mint 21 uses the Ubuntu 22.04 package, in the Ubuntu section.

For another distribution built on one of those above, such as Zorin OS on Ubuntu, use the package for the distribution and release yours is based on; your distribution's website, or DistroWatch, says which that is. AlmaLinux and CentOS Stream use the RHEL package on business downloads, or the Rocky Linux package on personal ones. If none fits, use Other Linux.

For a Raspberry Pi, see: Do I install ARMHF or ARM64 on my Raspberry Pi?

For the installation steps, see: Installing on Linux

Extended support for business customers

For business and enterprise customers, we support every system still in its vendor's paid extended support, such as Windows Extended Security Updates, Red Hat Extended Life Cycle Support, Ubuntu Pro or Debian Extended LTS.

On Synergy Business Advanced and Synergy Enterprise, custom LTS and legacy operating system support is part of your plan: when the current version doesn't run on your system, including where a cell below says None, we build it for you. On Synergy Business Essential, use the newest version below, or move to Advanced: Synergy Business

To ask for a build: Contact our business team

The newest version that runs on each today is in your product's section, below. For personal, non-commercial customers, these are legacy systems: use the newest version listed there, as it was released.

Legacy operating systems

These systems are past the end of their vendor's support, extended support included. Older versions of Synergy 1 and Synergy 3 still run on many of them. Every version of Synergy 1 and Synergy 3 is listed under All versions at the bottom of our download page, with no need to log in: Download page

For business and enterprise customers who need one of these systems, talk to your account manager: we can consider an exception, such as a build for it or a fix in an older version. If you don't know who your account manager is: Contact our business team

For personal, non-commercial customers, older versions come as they were released, without the fixes made since.

The newest version for each legacy system is in your product's section, below. If your system isn't listed there or in the next section, contact us and we'll look for a version that works on it: Contacting our support team

Operating systems from 1995 to 2006

Synergy Vintage, our founder's hobby project, keeps the original program alive, from its 2001 source code on, for systems such as Windows 98 and XP and Mac OS X Tiger. It's separate from Synergy 1 and Synergy 3, and its page says which download works on which system: Synergy Vintage

What follows depends on your product: Synergy 3 or Synergy 1

Synergy 3

Windows

• Windows 11 (x64)

Windows on an Arm processor? For business and enterprise customers: a Synergy Business license includes both products, so use Synergy 1 on all your computers, since it has a build for Windows on Arm and Synergy 3 has none. Its requirements are in the Synergy 1 section: Synergy 1

For personal, non-commercial customers: with a personal Synergy 3 license, you can ask us to build Synergy 3 for Windows on Arm: Contacting our support team

For other distributions, use the Synergy 3 Flatpak (x86_64 and arm64). Wayland support in Synergy 3 is experimental. For details, see: Wayland support on Linux

Synergy 3 stays paused after installing? Install the package for your release instead: when the package is for a newer release than yours (the Ubuntu 26.04 package on Linux Mint 22, for example), Synergy 3 opens but can't start sharing, so it stays paused and Resume does nothing. For the steps, see: Installing on Linux

Synergy 2

If you bought Synergy 2, you got Synergy 3 free, as a license on your account: Synergy account

Synergy 2 is no longer in development or supported, and Synergy 3 is a much better experience. If Synergy 3 isn't on your account, contact us: Contacting our support team

Newest version on each extended support system

Newest version on each legacy system

Because the protocol is fully backward compatible, even version 1.0 will work with the latest versions of Synergy 1.

Windows

On Windows 7, install the Visual C++ Redistributable for Visual Studio 2019 before Synergy 1 (1.14.6). The downloads are in: Windows installation problem: Service cannot start

On Windows XP (Service Pack 2 or later), the Synergy 1 (1.8.8) installer includes the Visual C++ runtime it needs. If Synergy 1 doesn't start after installing, install Microsoft's runtime, then install Synergy 1 again.

Microsoft's download: Visual C++ 2010 SP1 Redistributable (x86)

macOS (previously Mac OS X)

Using an older Synergy 1 alongside the current one? Computers on different versions of Synergy 1 work together, so a Mac on macOS 10.15 Catalina can run Synergy 1 (v1.14.6) while your other computers run the current version. Two things to set up:

• With TLS encryption on, when the older Mac is a client and the server runs Synergy 1 (v1.21 or later), turn off Require client certificates on the Network tab of the server's Preferences, because older versions can't send a client certificate. For the details, see: Updating to a new version
• Synergy 1 (v1.17 and earlier) can't read the serial keys we issue now, so ask us for one it can read: Contacting our support team
