KB81496464: Nexus - Problems with installer on Mountain Lion or Mavericks

Summary

When I try to run the Nexus installer on Mac OS 10.8 (Mountain Lion) or 10.9 (Mavericks), a message pops up stating that the installer is damaged.

Symptoms

Nexus Server/RIP

1. Open the Nexus 10.1.2 or 10.1.3 Intel disk image.
2. Double-click Nexus 10.1.2.mpkg or Nexus 10.1.3.mpkg to launch the installer.

A pop-up dialog appears, stating "‘Nexus 10.1.x.mpkg’ is damaged and can’t be opened. You should move it to the Trash".

NexusManager

1. Open the NexusManager 10.1.2 or 10.1.3 Intel disk image.
2. Move the NexusManager folder to the Application folder.
3. Open the NexusManager application.

A pop-up dialog appears, stating "‘NexusManager’ can’t be opened because it is from an unidentified developer".

Solution

1. Quit the Nexus installer or quit the NexusManager application.
2. Go to the Mac System Preferences and open Security & Privacy.
3. Click the lock to make changes and enter the Administrator password.
4. Change the setting Allow applications downloaded from: to Anywhere.
5. Now re-launch the Nexus installer and try to install Nexus again or try to open NexusManager again.

Workaround

If this solution did not work, the installer may indeed be damaged. In that case, please make a new personalized build on the Download Center.
