Problems with App Store since installing Mountain Lion

I have recently installed Mountain Lion and since then have been unable to use the App Store. When I launch it comes up with an error message stating 'App Store cannot verify a secure connection with the App Store.Would you like to connect anyway?'  If you hit continue the application flashes black and white but goes no further. Has anyone else had this problem and what could be done about it.
Regards
Walt

Yes at work and no at home but the problem occurs regardless of this

  • Any problemes with App. ONYX and Mountain Lion ?

    What could be the problems using Onyx ?

    How to maintain a Mac
    1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
    2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis. This is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible.
    3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this stuff is useless, or worse than useless.
    The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
    As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Use your computer; don't fuss with it.
    Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve.
    The free anti-malware application ClamXav is not crap, and although it’s not routinely needed, it may be useful in some environments, such as a mixed Mac-Windows enterprise network.
    4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
    There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
    Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
    In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most users don't.
    5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage consumption and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
    If storage space is running low, use a tool such as the free application OmniDiskSweeper to explore your volume and find out what's taking up the most space. Move rarely-used large files to secondary storage.
    6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

    here is a "copied" version with credits for those looking for a solution to an annoying problem Apple should patch.  (Yes, I'm aware of the irony of that statement)
    July 18, 2012 · by Arthur Lockman · in Apple, Tutorials
    After doing a reinstall of Lion a few weeks ago, I found that my computer suddenly would reject every VeriSign certificate that it encountered. Using Chrome, that meant that I couldn’t even access Twitter.com, because it thought that the certificate was wrong. I couldn’t login to the Apple developer portal, I couldn’t authenticate a device with XCode, I couldn’t make a purchase at Apple.com, I couldn’t download updates from the Mac App Store, and I couldn’t login to Mint.com, among other sites. I essentially couldn’t do anything that used a VeriSign certificate for SSL.
    What did I do? I called my trusty AppleCare advisor, hoping for an answer. I thought that maybe they could help me figure it out. After getting to senior support, I was told to reinstall Lion, which I did to no avail. My case was then forwarded to the Apple engineering team, with 3 to 5 days to wait until I had an answer. I looked around, through my console logs and through Keychain access, and finally came up with an answer, and a solution to my problems.
    It turned out that my solution was pretty simple. I had to delete a few files and reset one to its default setting.
    Delete the files /var/db/crls/crlcache.db and /var/db/crls/ocspcache.db. These can be found using Finder’s Go >; Go To Folder menu (Cmd + Shift + G). This resets the cache of accepted certificates in the system. It doesn’t remove them, it just forces the system to rebuild the caches upon restart.
    Open Keychain Access (/Applications/Utilities/Keychain Access). Select Certificates in the Category picker on the left side. In the search bar, type in the word Class. Look through that list, and find any certificates that have a blue + symbol over their icon. These are the ones you need to modify.
    Select one that has a blue +, and hit Command + I. Click the disclosure triangle beside the “Trust” list to show the list of permissions. Now, what we need to do is to set this certificate to use the system defaults. However, for some reason, when you select it, it doesn’t save. So what you need to do is this. Under “Trust”, where it says “Secure Sockets Layer (SSL)”, change the dropdown menu to say “No Value Specified”. Then, close the window. It will ask for your administrator permissions. Then, open the info pane for that certificate again. Under “Trust” again, now set the dropdown that says “When using this certificate:” to say “Use System Defaults”. You can then close out of the info pane, and enter your password again. Do this for any of the certificates that have a blue + on their icon. There should only be one or two at most.
    Restart your system.
    This solution seemed to work just fine for me. All of my certificate problems have been fixed. It must be something with the OSX installer that causes this certificate issue. I’ll file a bug report. Hopefully someone looks into it and fixes the flaw in the OS. And, I hope that this fixed the flaw for you.
    Addendum – a note on security:
    This procedure won’t affect the security of your Mac. I’ve had some questions come in about that, and if anything, it makes it more secure because then sites that require SSL certificates can actually use them, unlike before where they might default to non secure connections because the certificate was bad.

  • Since installing mountain lion i have a problem with mail. when i delete a message close  and open mail the message has come back. please help!

    Since installing Mountain Lion i have a problem with Mail. I delete a number of messages from the same person but keep the newest message in my Inbox. I actually delete them from the Trash. The next time i open Mail the deleted messages are back again. Can anybody please help as this is getting annoying. Thanks in Anticipation.

    Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.
    First, empty the Trash.
    Triple-click the line below to select it, then copy the selected text to the Clipboard (command-C):
    find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl \) 2> /dev/null | wc -l
    Launch the Terminal 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 Terminal in the icon grid.
    Paste into the Terminal window (command-V). The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
    The output of this command, on a line directly below what you entered, will be a number such as "41." Please post it in a reply.

  • I am having issues with my external hard drives since installing Mountain Lion

    I am unable to get my time machine to backup consistently on my external hard drives since installing Mountain Lion. One of my drives seems to have lost all data since installing Mountain Lion. Is this problem cropping up with other folks? BTW, all of my drives are Lacie brand.

    Do you mean, when you select it to be used for backups, the Preferences window shows "none"?  If so, that's not a problem.  That doesn't get updated until the next backup to that disk is finished. See #B3 in Time Machine - Troubleshooting

    Hi, since installing mountain lion on my macbook, it wont download pdf files from internet sites, the same problem does not exist on my mac mini, i am using firefox on both macs, please help!

    Back up all data.
    Quit Safari. In the Finder, select Go ▹ Go to Folder... from the menu bar, or press the key combination shift-command-G. Copy the line of text below into the box that opens, and press return:
    /Library/Internet Plug-ins
    From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then launch Safari and test.
    If you still have the issue, repeat with this line:
    ~/Library/Internet Plug-ins
    If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

  • Since installing Mountain Lion, Outlook 2011 crashes

    Since installing Mountain Lion, Outlook 2011 crashes.   A few seconds after opening I get this error message
    "Microsoft Outlook must be closed because an error occurred. Any unsaved work may be lost." 
    Tried rebooting, haven't yet tried reinstalling Outlook from disc.
    Other apps seem OK so far.
    Help is greatly appreciated.  

    Reinstalling Office 2011 did not fix the problem,  but on the Microsoft.com/mac site I found instructions for rebuilding the Outlook database (Identity).    This worked,  I no longer have the problem with Outlook 2011 Mac.

  • Is anyone else losing their internet connection since installing mountain lion?

    since installing mountain lion when I come home from work safari won't pick up the internet connection without rebooting.  Once rebooting everything works fine until the next day when I incur the same issue.  Any thoughts?

    Are you on 10.8.2 as ypur profile says? If so, it's worth updating to 10.8.3 which was released last week.

    Here's a link to some suggestions that helped some users with similar problems in Lion. May still be relevant to MLion. Also check the links within the article:

    Also when I had wifi problems in the past, creating a new network location resolved it:

    I've also seen threads where users with wifi problems have successfully solved them by changing the channel in the router's wifi settings.

  • Cannot send mail since installing mountain lion

    I'm using aol mail.  I receive mail with no problems. Since installing Mountain Lion on my new Mac when I try to send mail I get a message that I can't send using aol server.  Mail settup indicates everything is working fine. I have no problems sending mail with a Macbook Pro and a PC on the same wireless network.

    This seemed to work for me: First be sure all your mail is stored on the server (eg AOL) or you may lose it. If it is NOT stoerd on the server, DON'T DO THIS
    In Mail Preferences / accounts, use the -(minus) sign to delete All of your accounts one by one
    Now use the + to add account, and reinstall all of your accounts one by one.
    It does seem to work and mail is now sent

  • Unable to connect to Airport Extreme since installing Mountain Lion

    Unable to connect to Airport Extreme since installing Mountain Lion. If I go to Finder > Shared I can see it listed but then when I go to connect to it won't. I can see it in Airport Utility and connect to the internet but when I try and connect to the base station to use my hard drive / printer it won't connect?
    Tech Support tried saying it could be the devices attached don't have an update for them yet but doesn't explain why I can't connect to the base station. In their defence I can see it in airport utility so the base station does work with the OS X
    However I've just tried connecting by an ethernet cable and connects fine?

    Ok .
    Power down the base station (Mine is connected to a 4 way so i down powered base station, printer and hard drive) powered back up and now when I go to finder then look at the shared section I can view my files on the base station.
    Hope this helps
