I’m setting up a new hard drive and formatted it as exFAT. I liked the cross platform support and not having to deal with permissions when mounting the device. BUT it doesn’t support hardlinks, which I want to use for the *arr apps. Is NTFS the best pick, and I’ll just have to live with read only on mac?
I’d 2nd this: you’re using it for downloading media, so presumably one of the computers is the one running the actual software that’s doing that. Just share the drive over the network from there, and pick the best-supported FS on that platform.
