How to fix the “App Can’t be opened because it is from an unidentified developer” Error

OK, so let’s start with what the error is. Starting with “Mountain Lion” the OS defaults to preventing applications who aren’t updating their applications through the App Store (or from developers who haven’t identified themselves with Apple) from being installed.  You will see messages like the following:


The security feature at play here is called Gatekeeper. You don’t need to worry too much about what it is; just know that  you can still install/run the application(s).

Temporary Solution

This is the one that most people ‘should‘ choose, as it leaves the control over what is installed on your machine up to you, and with your knowledge, thus preventing potentially malicious software from being installed without your knowledge.

All that’s required of you is to Right-Click (Control+click) the application or package in question, and choose “Open”, then click the button “Open”.

open perms

You can do this with any application that gives you the warning.

Nice and simple.

Permanent Solution

Some of you may be more daring and live life carefree, and would like to disable this “Gatekeeper” security thingy altogether. Well, at least for now you can.

1. Open your System Preferences

2. Choose “Security & Privacy” – General tab

3. Click on the lock/unlock button (to unlock and grant permissions to make changes)

4. Change the “Allow applications downloaded from” setting from “Mac App Store and identified developers” to “Anywhere”.

5. You can now launch/install applications without Gatekeeper preventing you.

This post contains the answer to the “How many squares can you count’  puzzle on Facebook and Google + so be warned. If you haven’t already answered it, this is the time to get it your best shot.

The trick here is to count the number of squares you can see.  Majority of people tend to omit certain element as seen below. The original post claimed they could only find 27 squares. Majority of people will find 34, 36, or 38.  How many can you find?

Here’s the puzzle.

How many squares do you see in this image, we keep getting stuck at 27?


A lot of good guesses on the square puzzle that has been showing up on a lot of people’s timelines recently. Most tend to forget the 2 boxes that the 4 smaller boxes are contained in, and the 4 – 3×3 boxes.

The correct answer is: 40

Here’s how it done.

Mountain Lion USB Install Disk

Mountain Lion USB Thumb Drive

Before you start

You will need a copy of the OS X Mountain Lion installer. You obtain this by downloading it from the Apple App Store on your Mac.

When the download is complete, please do not run the installer. Rather “quit” the installer. If you miss this step you will need to re-download the installer before you can begin

Start the process by navigating to your Applications folder, where you will find the installer. The file you’re looking for is simply called “Install OS X Mountain Lion”.

Right click (or Control + Click) the installer and select “Show Package Contents”, and navigate to the “Shared Support” folder, where you will find the installer “InstallESD.dmg”. I would suggest making a copy of this file, and making a backup for it, just in case something goes wrong. (I put a copy into another “backup” directory)

Open a new Finder windows (Command+N or File>New Finder Window) and Navigate to /Applications/Utilities/ and launch the “Disk Utility”

Attach your USB drive (should be 8GB or more). Once it’s attached and the machine has attached the drive, you will find it in your drive list. Select the drive, and choose the “Restore” tab. Drag InstallESD.dmg into the file-open window and click open – or select Image, and select it by navigating. Next, drag your partition to the “Destination:” location, and drop. Click “Restore” (you will likely need to authenticate as an Administrative user.)

Generally, this process will take about 15-30 minutes. Once your disk is complete, relaunch your installer, and you’re ready to go!
