Continuing the discussion from OS X Yosemite testers?:
Nice fix! This is actually a setting in OS X that you can turn off. Unfortunately, there’s an additional tweak you need to do even after disabling the feature.
- Open System Preferences (Finder > Applications)
- Click the General button
- Check “Close windows when quitting an application” or UNcheck “Restore windows when quitting and re-opening apps.” It depends on which version of OS X you’re using that determines the name of the feature.
- Open new Terminal window (Finder > Applications > Utilities)
open -F /Applications/SketchUp\ 2014/SketchUp.appand press Return.
You only have to do this procedure once. You can open SketchUp normally from here on out.
