I was trying to demonstrate Roll20 to one of my players but the link is Hard Crashing his MacBook Air.
His Specs are
Model Name: MacBook Air
Model Identifier: MacBookAir4,2
Processor Name: Intel Core i5
Processor Speed: 1.7 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache (per Core): 256 KB
L3 Cache: 3 MB
Memory: 4 GB
Operating System: Mac OSX 10.7.4(Lion) All patches installed.
He needed to hard reboot his system every time he follows the link.
