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. Once an app is discontinued and is no longer receiving updates, some future macOS update will cause the app to stop working eventually. Inevitably, all software generally meets a similar fate. Since Transmit 4 was discontinued, it will not be receiving an update to correct these issues. 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. A note about Transmit 4’s compatibility with macOS Catalina and newer If you are looking for a specific older version of our software, you can find it at The Panic File Museum. Click the app version number below to start the download. You can find your operating system version by selecting “About this Mac” from the Apple menu in your menubar. Use the table below to select the appropriate version for your operating system. 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. If you need to download a version of Coda or Transmit for use on older versions of macOS please consult the compatibility table below.
