I have maxed out my 2007 Mac Mini with memory and OS X LION 10.7.5. The system functions perfectly. However, the 2017 release of Turbo Tax (and I presume other applications) will not support this OS X and I cannot upgrade to what the do support. So it seems I have a perfectly functioning boat anchor when it comes to "only supports the latest releases of OS X" applications. Will the latest manufactured Mac Mini hardware support OS X future releases? The 2007 hardware is what prevents it supporting anything above LION. I don't want to invest in another mini that turns into a boat anchor in the near future. ?Advice? ?Counsel? ?Comments?
