could not open app store

I couldn't launch my app store. I am using OS X 10.9.2


I even tried via "About this mac" and tried spftware update. It didn't seem to launch.


Cheers,


Joe

Disable anti virus software if installed



Make sure the firewall is turned off in System Preferences > Security & Privacy > Firewall





When you can launch the App Store, make sure Gatekeeper is enabled before downloading apps.


Open System Preferences > Security & Privacy then select the General tab.


Make sure either Mac App Store or Mac App Store and identified developers is selected.


If that area is grayed out, click the padlock icon to proceed.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES All Messages

from the log list on the left. If you don't see that list, select

View Show Log List

from the menu bar at the top of the screen.

Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please do not indiscriminately dump thousands of lines from the log into this discussion.

☞ Some private information, such as your name, may appear in the log. Anonymize before posting.

You ran a defective third-party "utility" such as "CleanMyMac" or "MacCleanse" that purports to "clean up" "junk" files. What it really does is to corrupt the operating system and many applications.

The first thing you need to do is remove that software according to the developer's instructions. Never install it, or anything like it, again. Then see below.

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.

If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.

There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.

*The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.

Hi there Linc,


you are correct, I have used 'Clean my mac" and soon as I sa your reply, I immediately removed it as per developer instructions. I am sorry, I shall never again deter from the 'apple authorised' path.


Now that I have deleted the demonic application, I shall back up my data... This will be my first time so i am a bit nervous. I do have 16 gbyts left from a total hard drive space of 120 gbyts. Is this enough? How do I go abouts backing it up.


Thanks Linc. Or should I say, 'my saviour'....


Cheers,

joe
