Hi, Having suffered the frustration of losing work due to Illustrator unexpectedly crashing, I decided to write Ai Auto Save. It's a menu bar app which will save unsaved changed to open Illustrator documents. Check it out here. https://itunes.apple.com/us/app/ai-auto-save/id877602617?ls=1&mt=12 Hope you find it useful. If so, please leave a review on the Mac App Store, if not then send me a Private message or leave feedback here on MacRumors. Thanks
Just to keep you posted, we'll be discounting a number of our products including Ai Auto Save for one day only, "Black Friday" (28th November 2014). Watch out Twitter feed for details! @ghostotter_mac
