Well, the Mac version doesn't support VST's directly, but you can route MIDI to the standalone version of SampleTank as shown below :

It works well, and with very little latency.
Now, that is assuming that all your licences are cross platform, and you have Mac versions of all your SampleTank content.

Hopefully this helps.
