On the 24" iMac I'm using at work I cannot scale the iOS Simulator's window. The 100% and 50% menu entries are greyed out (and the keyboard shortcuts don't work either.)
On my Mac Mini at home, it's fine. I've searched high and low for someone with a similar problem, and can't find anything logged. Any ideas?
The options will only be there if your screen is not large enough to show the window at 100%.
