My 2.5 yr old mac has some issues: airport won't recognize secure connections, calendar and clock reset upon a shutdown/reboot/battery dies, when installing software updates, the system never fully recovers--I get a blue screen with a grey spinning dial on bottom center of the screen (so I end up forcing a shut down and reboot).  My computer also gets really hot and runs really slowly.  All of these issues happen sometimes, not all the time.  I took my computer into Best Buy (when it was still under warranty) for a screen/display issue and told them about these other problems I was having.  They weren't much help, but explained the clock and calendar reset every time because there wasn't a device to keep them current.  Weird because the clock and calendar didn't do that the entire first year I had the computer.  If I update to Mountain Lion, will this solve the issues?  Am I doing something to cause these issues?  I also can't get java to work.  Is that related at all?

    airport won't recognize secure connections

    First contact your ISP.  You need to confirm that the issue is not on their end.

     

    Change your router channel.  Sometimes this is all you will have to do.

     

    Power cycling the router.  Read the router's user manual or contact their tech support for instructions.

     

    System Preferences/Internet & Network/Network

    Unlock the padlock

    Locations:  Automatic

    Highlight Airport

    Click the Assist Me button

    In the popup window click the Diagnostic button.

     

    System Preferences/Network- Unlock padlock.  Highlight Airport.  Network Name-select your name.  Click on the Advanced button.  Airport/Preferred Networks-delete all that is not your network.

    Place a check mark next to "Remember networks this computer has joined."  Click the OK button and lock the padlock.  Restart your computer.

    No internet connection (wireless)

    Check to see if an extra entry is present in the DNS Tab for your wireless connection (System Preferences/Network/Airport/Advanced/DNS).

    Delete all extra entries that you find.

    Place a check mark next to "Remember networks this computer has joined."

    If using one of Apple's Airport routers, read its user manual or post in its forum area. If using a 3rd party router, read its user manual, contact their tech support department/website or post in its forum area.

     

    calendar and clock reset upon a shutdown/reboot/battery dies

    To check for a bad battery, go to Apple/About This Mac/More Info

    In the System Profiler window, select the Power entry & look for Health Information.

    If next to Condition it says "Check Battery" then your battery is probably on the fritz.

     

    when installing software updates, the system never fully recovers

     

    Please provide details.

    I get a blue screen with a grey spinning dial on bottom center

     

    Safe Boot by restarting your computer while holding down the "shift" key.  Safe booting disables all nonessential processes, often times allowing you to start up when you would otherwise crash.

    A corrupt cache here can cause the blue screen crash.  Once you restart normally, the cache will be recreated.  This should take care of the issue.

    Or go this route -

    Press the Power Button and immediately press and hold down the Command  and the S keys as the machine starts up.  This boots you into Single-user mode and you should see white text appear on the screen.

    When you see the # Command prompt, type /sbin/fsck-fy and hit the Return.

    Now sit back & let your computer do its thing.  This should take approximately 15 minutes or so.  Depending on how messed up your computer is.  Just be patient.

     

    If and when you see the message File System was modified repeat the steps above again & again until you hopefully see the message "no problems were found."  When that happens type reboot and hit Return again.

     

    If these steps do not work then boot from your install disc to repair disk.  To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.

    Select your language.

    Once on the desktop, select Utility in the menu bar.

    Select Disk Utility.

     

    Select the disk or volume in the list of disks and volumes, and then click First Aid.

    Click Repair Disk.
