I have read a little bit about Catalina OS, and it seems like it has what I have been wishing macOS could do for a long time; be able to read and write directly to apple devices through finder without iTunes. I would love this functionality on my desktop, however, I have read that pre 2013 mac pros will not be able to run Catalina. This is disappointing because I have the old cheese-grater mid 2010 mac pro. So I looked at other mac pros like the 2013 trash can one, since 2013 and newer are Catalina supported, they were interesting when they first came out, and were way too much then, but now I see some on eBay and they have come down in price. My question is, would it be worth it for me to get a 2013 on eBay, to get the newer hardware that can run and support Catalina, and sell or do something else with my mid 2010 mac pro? or should I hang with my current mac pro and see if I would be able to get Catalina on it in the future? Would the 2013 then be too old to run MacOS after Catalina? I would get this with the idea that it would be able to get at least maybe 2 more macOS upgrades after Catalina. I have seen a thread where there are some already working hard trying to find a workaround to get Catalina to run on pre 2013 mac pros. It looks like it would be some hoops to jump through to run Catalina on a pre 2010 mac pro, like hacking, and I am questioning whether it would be worth it to get all the hardware and software updates and upgrades for my mid 2010 mac pro up to Mojave and then hope to be able to run Catalina, or just move on to a newer mac pro. The new current mac pro is just way out of my budget, hence why I went to ebay to check out the 2013 ones. I know there are iMacs and the iMac pro, but I want something that is somewhat modular so I can swap out something if need be.
