My main machine is a 2008 Mac Pro, but I would like to use Sierra and future macOSes. While there are no significant issues with my machine now (a few random shutdowns/reboots), a speedier machine with the latest updates would be nice. An upgraded 2010 machine with a W3690 3.46 Ghz 6-Core and 32GB of RAM is available for $800. This would be used all day... browsing, office-type work, Photoshop and Handbrake type stuff. Probably not much of deal but I don't want to rely on a Hackintosh as my main machine. Any opinions or suggestions? Thanks!
