OSX has taken to ignoring the "allow from unauthorized source anyway" option, even if you give it an administrator password.

There is however a work-around.

1 Launch System Preferences.

2 Go to Security and Privacy.

3 "Click the lock to make changes"

4 Enter your admin password.

5 Change the "Allow apps downloaded from" to "anywhere".

6 Close System Preferences.

7 Try to install your unauthorized software.

8 Authorize the system to "run software downloaded from the internet?"

9 Enter your password again if asked.

10 Once the software successfully launches, quit it.

11 Launch System Preferences/Security again, and "click the lock to make changes", and re-set your security "Allow Apps" setting to "Mac App Store and Identified developers". Quit System Preferences

12 Re-launch the software. It should launch without complaint.

13 Grumble about idiot security procedures necessitated by the fact that application installation, and system configuration/software modification are not properly privilege-separated, as any sane system configuration that did not cater to nincompoop users should have done...

Subject: vmd-l: unable to install VMD on OSX


I tried installing VMD on OSX. I could download the dmg file but was unable to open it. I went to settings -> security and privacy and clicked on open anyway, typed in the password...but still it refused to open saying that it was from an unauthorised source.

Can you please help?

Thank you in advance!
