I have two identical Xcode icons in the Launchpad. I guess the second icon appeared after installing Xcode beta.
So here my steps for reproducing this issue:
- Install Xcode 7.
- Install Xcode 8.
- Install Xcode 7 again.
I tried this but it didn't help me. I have OS X El Capitan 10.11.6.
How do I remove the duplicate icon?
