About the Mac


I recently updated to Yosemite and now I am having problems with the above mentioned apps, not opening at all.


I am unable to check to which version its update to, or even update to next version.

    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 use any iWork applications, you may need to delete them and redownload them from the App Store.

    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, usually 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 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.

    First of all thank you for replying.

     

    I have followed the steps you have mentioned. I reinstalled the OS, it worked only till I installed Java, the same problems appeared again, So I reinstalled again, it works now.

     

    How do I get rid of this message. "To view this web content, you need to install the Java Runtime Environment."

    Most likely, you have a web plugin that depends on the Java runtime distributed by Apple, such as the Facebook video calling plugin or the "NexDef" plugin for watching baseball streams. If you no longer need the plugin, remove it, including its automatic update mechanism (if any) according to the developer's instructions. Otherwise, install Java.
