Description of issue:

I’d like to install Sonarr 4 on an old Mac Mini Mid 2011 model (machine identifier: Macmini5,2), but I just realized that Sonarr 4 won’t run on macOS 10.13 High Sierra which is the last supported version of macOS for that model.

Before I jump through hoops to install a patched version of macOS 10.14 Mojave, I wanted to confirm that Sonarr 4 will in fact be compatible with it.

An old beta announcement on Reddit seemed to suggest that Catalina was needed.

However when I attempt to run the app the message there indicates 10.14 is required at minimum:

Appreciate info the minimum supported macOS version and any other gotchas I may run into on an older machine like this (e.g., dependencies, hardware issues, etc.)

Thanks much.

Sonarr v4 uses .net 6, the minimum versions for it are listed here:

Looks like 13 is the lowest supported version.

Keep in mind Sonarr v5 is in active development and will replace v4 when it is released. It will use .net 10, which has different supported OS versions:

Thanks for the quick reply.

So by 13, you’re referring to macOS Ventura, correct?

Correct, Ventura 13.x, not 10.13.
