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.
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".
A pop-up dialog appears, stating "‘NexusManager’ can’t be opened because it is from an unidentified developer".
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.
Newer OSX versions don`t allow "Anywhere" anymore and with this Nexus can`t be installed. To deactivate the "Gatekeeper" you can also use "sudo spctl --master-disable" in the terminal and confirm it with your password. Then in your security options the old view with the option "Anywhere" will pop up. Of course this change can be undone by "sudo spctl --master-enable" in the terminal.
