There is a Unity issue that prevents the fuzzy finder from opening when pressing Ctrl+LMB on Mac OS X. Any of the following methods will work as a workaround:
- Using RMB on an external mouse
- Using the trackpad's secondary click
- Using Cmd+E
- Disabling Preferences > Bolt > Skip Context Menu to access the fuzzy finder via Add Unit
For more explanation about the issue, see this comment.
