OS X Mavericks 10.9 Update

OS_X_Mavericks
I would like to recommend that you tell your staff to slow down on updating to the latest and greatest operating system.

At least three days to make sure everyone else catches all of the bugs.

The new Mac OS still has issues with Java and does not play nicely with PowerTeacher.

At least its Free!
