You can store patches by dumping them into a sequence track. You'll need to have both midi in and outof your synth hooked up to your Mac's sequencer, locate the parameter on your synth which will send (transmit) a system exclusive message (data dump), this usually will be found on the midi or master page. Set your sequencer and synth to matching channels, enable record on your sequencer and press "send" system exclusive on your synth. Reverse this process to load these programs, set your synth to "receive" system exclusive and play the sequence, again on matching channels.
