I was scrolling down the page, thinking, "this application looks great, I have wanted something to replace iTunes for years. It plays FLAC _and_ ALAC! I would love to pay money for this."

But I don't currently have a mac running anything later than Mojave, 10.14.

And the primary machine I would want to host music on can't upgrade past it (2010 Mac Pro, 12 cores, 64 GB Memory, 4GB GTX 770, 4 easily-swapple internal hard drives, all in spent under $1,000, used, parts and all - not a bad deal, would anyone agree?). Of course, I'll probably be moving it to Linux at some point after Apple gives up on 10.14.

I'm a very atypical case these days - I don't stream music, I actually buy CDs sometimes (often cheaper on Amazon shipped to your door giving you a hard copy backup and freedom vs buying the digital version they offer). I like to repair and upgrade older hardware. This kind of music player is right up my alley.

I'm not trying to complain. This is awesome. Maybe I'll buy it anyway just for whenever I get around to upgrading my macbook.

I wanna chime in to say that's a great Mac. You could use a patcher to get it to Catalina but I definitely wouldn't go any higher. That will extend software support life a bit more.

Honestly, it's unlikely. I'm gauging interest, and while there is some, I have to weigh it against the extra dev time (and other things like compatibility, support etc).

I'm just one designer/developer, so I'll need to see fairly substantial demand before I can commit to it.

Not what you wanted to hear, I know, but hopefully it makes sense!
