> couple of decades ago I worked at a company that had about 200 Mac's and a similar number of PC's. One of our favorite practical jokes was to disable the mouse on Mac's. The victim quite literally could not do a thing with the computer until the mouse was re-enabled. This doesn’t sound right. I once installed a corrupted version of OS 10 Jaguar on my laptop that resulted in a non-functioning mouse and touchpad. I managed to reinstall the old OS using only the keyboard. Prior to the post-Snow Leopard era when they started stripping down the file system and muddying the navigation, OSX’s interface was really easily navigable.
