I have put up a tvOS repository containing repackaged / rebuilt jailbreak tools at https://tv.unbuffer.com
This was mainly to support pentesting of a few applications for clients. I found that the Apple TV jailbreak ecosystem lacked current versions of many tools that I had came to rely on. I created it for personal use, but hopefully it will save other people some time and effort during their Apple TV application penetration testing endeavors.
Currently this contains Frida and AppSync Unified though I may add more tools in the future.
Get in touch at mail<at_nospam>unbuffer.com or via stuartw1 on GitHub if you have feedback / bug reports.
