Any of our PC Connect weather stations, and the smartHUB would work on a Mac computer. With the PC Connect display you would need to keep the display plugged into a computer at all times, run the software on the computer at all times, and keep it online and on at all times. The PC Connect will transmit the readings from your outdoor 5n1 sensor to My AcuRite. The smartHUB plugs directly into the router via an Ethernet cable. You can have up to 10 compatible sensors on the smartHUB. You can view the information via a tablet, smart phone and computer for both the PC Connect display, and smartHUB.
