I've always been able to preview AI files in finder. But one day the feature just stopped working and I found this on an Apple thread that brought back the functionality:
1. Open to the Preferences folder of your home directory, or from Finder>Go>Go to Folder, copy & paste:
2. Delete the com.apple.finder.plist
3. From the Finder icon on the Dock, hold the control option key and click the Finder icon>select Relaunch.
Hope this helps!
