I have a love-hate relationship with Smart Guides, but I need them. After installing Illustrator CS6 (Production Suite) on my Mac Pro (2 x Quad-Core Intel Xeon, 12 Gb of RAM) I can't toggle Smart Guides on! Whether there is a check next to the menu item or not, it doesn't matter. I've gone into Preferences and turned on everything under the 'Smart Guides' section... nothing.
Help me! I need my Smart Guides!
