I just updated to Mountain Lion and now time machine won't recognize my backups from before the update.

I updated from Snow Leopard OS X 10.6.8 to Mountain Lion OS X 10.8.2 on my MacBook Pro
I used disk utility to restore my external hardrive because I read somewhere that that would fix the problem.
It did fix the problem but only temporarily. I was able to view my backups from Snow Leopard, but as soon as I tried to backup again, time machine was stuck
"preparing to backup" for 5 hours and when I quit the prepare I could no longer access my previous backups.

So what happens if you go to System Preferences > Security & Privacy > General? Are you able to go there at all? If you are able to go there, can you unlock the preferences using the lock in the lower left and your login name and password?
If you are able to do this, can you change the "Allow applications downloaded from:" to Anywhere?
Best of luck.

    Since you haven't answered any question yet, I'll add another to the list.
    What version of OS X were you running prior to the upgrade?

    Hi again, when you clicked on Mountain Lion and Lion in the App Store you are telling the laptop to reinstall them both.
    You may have allowed simutanious downloads checked at the bottom of the window, I don't know, but I expect Mountain Lion is downloading, so Lion is waiting for it to finish, so if you have Mountain Lion installed cancel both download's.
    Cancell both downloads anyway.
    Go to the apple logo , top left, click on it, then click on about this mac, a window will open telling you what's installed,  Mountain Lion is OX 10 version 10.8.2 click on more info, to find out more, Lion will be OX10 version 10.7.4.
    Only update were it say's check for updates, not download now.

    I just updated to Mountain Lion and now I notice on the side bar under "shared" an icon of a computer. It states that it is a memory card.  What is this? I can't seem to open it. FYI: my wifi router is password protected.  Thank you!

    Do you have a printer that has a memory card slot on it?

    I've updated to Mountain Lion and now when I download a purchased program nothing happens (it jumps to download but the download will not open?)?

    Hi, Thanks for responding.  Most downloads you can double click and/or drag over to applications for it to actually install however this one you can't.  It just acts like an empty folder and does nothing.  I did update to Mountain Lion recently and wondered if it was incompatible or something or if I was doing anything wrong?  Thanks.

    Make sure you have the latest version of parrallels. Think older versions are not compatible.

  • I updated to mountain lion and now mail cannot connect to my server

    I updated to mountain lion and now mail cannot connect to my server.  It says check your user name and password are correct.  Well they are, and were.  Nothing has changed except the mac OS. 
    Has anyone else suffered this and knows a way around it?  Too annoying to log into my mail every 15mins via a web page anymore.
    Efforts tried to resolve this so far:
    retyped user name and password, removed account and created a new account, restarted computer, software update, searched forums.  so far all have proved unsuccessful.
    I have also written to my mail provider and am waiting for feed back from them, but if anyone has any advice it would be gratefully received.
    Many thanks,
    Mike

    Many users upgrading to Mountain Lion have run into this problem, myself included.  You likely have corrupted settings for your  "Outgoing Mail Server (SMTP)" for each of the failed Accounts.  Open Mail>go to Mail's Preferences>Accounts>select an Account in the left column to work on>then set up your Outgoing Mail Server which will INCLUDE resetting up your Password, as its asking you to.  Click on "SMTP Outgoing Mail Server" near the bottom of the Accounts window while your mail account is highlighted in the left hand column.  When you click on SMTP... you will see a drop down box icon offered at the right side of the line.  Click it and then select at the bottom of the the list "Edit SMTP Mail Server".  Fill in the required settings for your ISP mail account using their recommended settings.

  • Updated to Mountain Lion and now I get a Green Flicker

    Help Please...
    I updated to Mountain Lion and ever since then when I export media from Final Cut X I am getting random green flashes in my video clips. I shoot with a DSLR (60D), full 1920x1080 HD, H.264 codec. I have never had this problem before.  I thought at first it might be the camera so I pulled out a different DSLR (rebel t2i) and it was having the same issues once exported.  The only thing that has changed is that I installed OSX Mountain Lion.  Any one else had this problem? It appears there are no updates available for my computer.  I am on a mid 2011 27 inch iMac.  Any help would be greatly appreciated.

    I am using magic bullet looks 2.0 as well.  From my experience so far it hasn't made a difference whether I actually applied the effect or not.  I am still testing to make sure but I think the green flicker has happened on clips both with magic bullet applied and ones not applied.

    You can either buy iLife 11 which will update or download from the App Store, which doesn't have iDVD.

  • I have updated to Mountain Lion and now the music on NetHymnal does not play.

    I have upgraded to Mountain Lion and now the music on the NetHymnal site does not play. There doesn't seem to be a problem with the sound on other sites. There is a statement that a plugin is missing but I can't determine what plugin is missing.

    Do you have a printer that has a memory card slot on it?

  • Updated to mountain lion and now I get continual errors in PS!

    I have the latest version of photoshop CC. Since updating to mountain lion 10.8.5 from lion PS CC doesn't work properly. Several of the tools gives me 'unable to use tool due to program error'. This is useless! I have installed the latest version of photoshop CC. It worked fine before. I can't use the eyedropper but the clone tool is fine. The brush tools are fine. Several of the other tools give this error. I can't see why some would work and others don't.
    I worked fine in Lion so there is no reason it shouldn't work in mountain lion. It's so frustrating as it means I cannot use the software I've paid for. I updated via the adobe update manager as the CC desktop system doesn't work
    What causes this error message?
    Everything is identical to what was there before - late 2011 imac with loads of memory and a wacom bamboo tablet driver with an older graphire tablet. No hardware has changed so it has to be a software error of some kind. The tablet driver is the latest one that works with the tablet I have and that works with mountain lion. I can't alter the version of that.

    Try these steps to fix most issues: http://bit.ly/Troubleshoot_PS
    I suspect either preferences restore or troubleshoot permissions with new Admin account will solve or give us more clues.

  • I updated to Mountain Lion and now I have problems

    After I updated to Mountain Lion my iphoto, imovie, numbers, pages,keynote will not open it has an error that says, You can’t open the application “Pages.app” because it is not supported on this type of Mac.What do I do now?

    I've read that if you update to Mountain Lion 10.8.2 this behavior has been "fixed."
    Most users blame the implementation of Save As… as not working as it has in the past. I believe the issue is that autosave will save all changes but you can revert the original document to a previous version. Click the small triangle next to the document name in the title bar & choose browse all versions.
