Question

Installed XCode 6 on Mavericks. It din't run. Updated OS to Yosemite 10.10 : Now Xcode.app (installed through *.dmg) launch fails with error message “Xcode” is damaged and can’t be opened. You should move it to the Trash. Updated to XCode 6.0.1 through App Store. Still no luck. Same error message. Anyone with a fix?

Answer 1

Some times in below options

• Open System Preferences
• Click on "Security & Privacy"

Allow apps downloaded from contains only 2 options "Anywhere" is missing for that open your terminal and add below line

sudo spctl --master-disable

enter your system password. Now you quit System Preferences and reopen it System Preferences/Security & Privacy/General now "Anywhere" option will be there. Hurrah You have done it.

hope it will work for you.

Answer 2

I experienced this error with any new added application under (all) macOS Sierra builds.

The only solution that worked for me was to execute :

xattr -rc /Applications/<faulty application>.app

You can also use the following command to "repair" all applications :

xattr -rc /Applications/*.app
