This tiny tutorial will help you to install third party apps on Mac OS X which is not allowed by default by Apple Inc. It will take just 10 seconds to enable third party app installation. This command reverses the spctl -master-disable command that you ran to set Gatekeeper’s “Allow app downloads from” setting to “Anywhere.” Final Thoughts Gatekeeper is a very strong security feature that is meant to protect your Mac from malware and otherwise harmful software.
Tip
Hey,
A new feature in Mountain Lion is the ability to protect your Mac from running applications that are not from authorised developers. This means developers from the App Store and identified developers apps will run normally. Those apps that are from other sources will automatically be disabled, and not run. This is a security measure to ensure no malicious code runs on your Mac. However, if you like downloading and running apps that are not from the usual source, you may want to turn this off. This post will show you how.
- You can set your Mac to download apps only from the App Store or from identified developers. If you download from an unidentified source, you have to authenticate.
- Using the Terminal is the best way to allow installation of applications on your Mac without the tedious process involved in making exceptions for each one of them. Using this method, you can install and use applications as you wish regardless of their source. Opening apps from unidentified developers are not for everyone.
Allow Alternate Applications To Run
To allow any application, downloaded from any source to run you need to change a system preference setting. Open up system preferences in your applications folder. Select the Security & Privacy preference. Under the general tab there is an option to select which applications run depending on there download source.
This little system preferences option will allow you to change settings.
Allow Downloaded Apps To Run On Mac
You can then pick the option you want. If you want to be very safe you can pick Mac App Store only. If you want to run your computer normally I would select the second option of Mac App Store and identified developers, I don’t see why it has to be any more strict than this. If you want an app downloaded from anywhere to run you select the option entitled anywhere.
Its a simple setting, however if you experiment with applications downloaded from various sorted, you may want to select the third option.
