Arctic is nothing like Final Cut Server in any way, shape, or form, apples to onions. I used to design and install FCSvr systems pretty much full time, until Apple killed it off and left a lot of folks high and dry. FCSvr was based on Post-Gres database, which has evolved since then, and was able to work with any NLE, but integrated with legacy FCP way more tightly than anything else. It was a best of class media server and nothing since has come close. Although I'd recommend You'd have to install a 2009 version of Post-Gres, also. No clue where you'd get that. And Apple has integrated it into macOS so much, you'd probably have conflicts. I highly doubt any macOS version after 2009/2011 would run FCSvr. That said, look at KeyFlow Pro and Kino, they're the closest you'll get to that with FCPX today.
