My experience has been that going through the types of barriers that may be present in your situation (cement walls, dirt, outdoor siding, possible chicken-wire-plaster in older homes, etc) you would have much better luck placing at least one z-wave device as a repeater (any lamp dimmer module would work) on the first floor of your home, somewhere between the Mac mini and the garage.
This would allow the z-wave message to be transmitted up to your 1st floor and then get repeated out toward the garage. This is much better than the RF signal trying to permeate the ground and foundation of your home -- hoping to reach the garage. If you have a Lowe's nearby (or don't mind Amazon) they sell the GE 45635 outdoor module. It is always in-stock as it is part of Lowe's Iris home automation system (really bad system-tries to mix WiFi, zigbee and zwave) This, in my opinion works wonderfully as it is an outdoor module and can be placed BETWEEN the garage and the house. It is a low priced alternative to some of the dimmer plugs that you will find on the market -- and repeats both normal z-wave signals as well as the z-wave beaming and encryption standards.
Placement 1/2 way between both locations is best. As earlier stated by Matt and Jay, a vertical USB stand would help immensely -- pointing the button on the Z-Stick toward your garage.
