I'm a disgusted user of Photoshop with their new CC software so have just recently researched and found Affinity Photo software. It is quite appealing but I may have a hardware problem. I have a Mac Pro dual quad core machine with 32 gigs of ram, multiple hard drives, raid system, etc., but is an early 2007 machine and can only run Snow Leopard 10.6.8 although it is set up as a 64 bit OS. Is there any version of Affinity Photo that will operate with my computer? Can't afford a new Mac so this may be my Achilles heel, but thought I'd ask before giving up any hope of finding something other than Photoshop. Thanks in advance.
