How many versions of macOS are typically supported for each app?

Each major update will always support the current and previous versions of macOS. If you need to download a version of Coda or Transmit for use on older versions of macOS please consult the compatibility table below.

  1. Can I upgrade from Mountain Lion to Catalina? The following versions of OS X and macOS can be upgraded to macOS Catalina. If your Mac is running OS X Lion or Mountain Lion, you must upgrade to El Capitan before you can upgrade to Catalina.
  2. Can I upgrade from Mountain Lion to Catalina? The following versions of OS X and macOS can be upgraded to macOS Catalina. If your Mac is running OS X Lion or Mountain Lion, you must upgrade to El Capitan before you can upgrade to Catalina. If your Mac is running Mavericks or newer, you can proceed to upgrade to Catalina.
  3. Open the disk image, then open the.pkg installer inside the disk image. It installs an app named Install Version Name. Open that app from your Applications folder to begin installing the operating system. MacOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion.

If you’re running High Sierra (10.13), Sierra (10.12) or El Capitan (10.11), upgrade to macOS Catalina from the App Store. If you’re running Lion (10.7) or Mountain Lion (10.8), you will need to upgrade to El Capitan (10.11) first. Learn more about how to upgrade to macOS Catalina.

While we'd like to be able to provide support for even older versions of macOS, this isn't always feasible and can in some cases prevent us from being able to take advantage of the latest improvements in the operating system.

A note about Transmit 4's compatibility with Catalina and Big Sur

Unfortunately, Transmit 4 was discontinued nearly two years before macOS Catalina (10.15) was released, and is incompatible with any version of macOS newer than macOS Sierra (10.12.5). If you choose to run Transmit 4 on an OS newer than Sierra, it will launch and work in a basic form, but you may notice some instability in the form of crashes, exception errors, or hangs.

Since Transmit 4 was discontinued, it will not be receiving an update to correct these issues. Inevitably, all software generally meets a similar fate. Once an app is discontinued and is no longer receiving updates, some future macOS update will cause the app to stop working eventually. Transmit 4 had a nice, long, seven year run but it was time to lay it to rest in favor of developing the next evolution, Transmit 5.

If you find that Transmit 4 is incompatible with your OS, the best option would be to switch to a different FTP client, be it one of the many free ones out there, or optionally upgrading to Transmit 5. Transmit 5 was released in July of 2017. Versions 5.6.0 and newer are fully compatible with modern versions of macOS.
