Gatekeeper

there are times when your organization/company locks down your computer and you have to install software. Here is how to gain access to install software.

Obviously you will need to have root access. Most of the time, if you are configured as an administrator on the Mac, you will be able to gain root.

1. Open up Terminal
2. Run this command $ sudo spctl –master-disable

spctl is the Mac’s SecAssessment System Policy Security.

What we are doing is Disabling the assessment subsystem altogether. Operations that would be denied by system policy will be allowed to proceed; assessment APIs always report success. Requires root access.

creating a USB install disk is super easy now.

1. Download the Mavericks installer
2. it should be located /Applications/Install\ OS\ X\ Mavericks.app
3. Open up terminal and navigate into the Resources section of the app
/Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources
4. Run the following command:
sudo ./createinstallmedia --volume /Volumes/ToFormat --applicationpath /Applications/Install\ OS\ X\ Mavericks.app

* notice that we named our volume “ToFormat”, you must insert the name of the volume you want to reformat.
** there are some other instructions on the internet, which require you to search for the base system.dmg, but the issue with that method is that it does not automatically create a recovery hd partition, so that features like file vault are not available.
