Gents, lets get back to the original question of the OP. Let's hope (s)he is still following the thread. Amibroker can be run on OS X using Wine or Codeweaver with minor annoyances (copy and paste from some outside Amibroker source is not working properly) - well I can live with that.
One of the things I just do not like is that Apple still asks premium prices for old technology - with my low CPU requirements I am seriously considering the PC-FIT intense PC with an i7 CPU for the price the base Mac mini is costing. And instead of a one year warranty I'll be getting 5 years.
Another item is that Apple's software support for older hardware stops sooner than I like. On the outside the Apple Mac mini is a nice compact box and I like the internal power supply but inside it is fragile. One has to be very, very carefull when replacing the HDD with a SSD let's one break of one of those connectors and be up for buying a new logic board which pricetag is plain ridiculous.
Take a look at an Intel NUC
Runs better than windows too
