Every since I installed Mountain Lion, I've had the issue of my MacBook Pro freezing up while it checks for Wifi after waking up from sleep mode. I have to constantly restart my computer. I'm wondering if Apple is aware of this happening on other computers and not just mine.


Also, my laptop is considerably slower since installing the OS update, especially when I turn on my computer.
