Cannot open any https or ssl apps, have upgraded to mountain lion. Have open all ports outgoing and even tested via hotspot on my iPhone, have changed MTU to 1300....help??


Cannot load any https sites..

MacBook Pro, OS X Mountain Lion (10.8.2)
  • Munas Level 4 Level 4 (1,260 points)

    First, the process by which OS X checks the validity of root SSL certificates doesn't currently work behind the authenticating SOCKS proxies used on some enterprise networks. If applicable, contact your network administrator. The proxy server may need to have its settings changed.


    Disable the built-in application firewall, if it's in use. If you're running a third-party firewall such as “LittleSnitch” or “Hands Off,” disable that. Test.


    In some versions of OS X, Parental Controls has a bug that prevents loading of secure websites. Turn it off.


    Are the current date (including the year) and time shown on your system clock? If not, correct them and test.


    Otherwise, launch the Activity Monitor 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 Activity Monitor in the icon grid.


    Select All Processes from the menu in the toolbar of the Activity Monitor window, if not already selected. Enter "ocspd" (without the quotes) in the "Filter" text field. Is a process with that name listed?


    If not, select Go Go to Folder from the Finder menu bar. Into the text box that opens, copy the following line of text:




    From the folder that opens, move these two files to the Trash:





    You’ll be prompted for your administrator password when you do this. Then reboot, empty the Trash, and try again.

    This is an HTTPS site. How are you connecting to it?

    On my iPad....

  • Linc Davis Level 10 Level 10 (173,960 points)

    Is the iPad on the same network as the Mac? Not on a cellular network?

  • VicanZa Level 1 Level 1 (0 points)

    Yes, iPad, iPhone and 10 other PC on network didn't have this problem on snow leopard.

    Please read this whole message before doing anything.

    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

    The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.


    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    • Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    • When you see the gray Apple logo, release the shift key.
    • If you are prompted to log in, type your password, and then hold down the shift key again as you click  Log in.
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.


    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.


    Test while in safe mode. Same problem?


    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    Will give it a go tomorrow, thanks again.
