Problems with computer  after upgrade to Mountain Lion.

I've had a slew of problems after the upgrade. Opening up virtually any programs takes longer, things unexpectadly freeze and the overall performance of my computer is very poor. I even had to do a light reformat of the hard disk because the OS would not start.  After speaking with a Mac rep in L.A., I was told that my processor (Dual core 2) might not fast enough for the software. I asked him if upgrading the Ram would help and he stated that it probably wouldn't.  This is both extremely dissapointing as well as upsetting. I'm a small business and cannot change computers every 2 years.  At this point I really regret upgrading and wish that there's something I can do to bring back the older operating system that I had when I purchased the computer. I own a 2010 Mac Book Pro. Any suggestions would be greatly appreciated.

  • ITunes doesn't sync iCal with iPhone after upgraded to Mountain Lion

    iTunes doesn't sync iCal with iPhone after upgraded to Mountain Lion. I even tried to use Replace Information On This iPhone and it doesn't work. Any idea guys?

    I'm having the same problem. It's as if my iPhone and MacBook Pro now have two separate calendars.
    Basically, I have a MacBook Pro (Mountain Lion, 13", late 2011) that I sync via USB with an iPhone 4S (iOS 5.1.1). Before upgrading to Mountain Lion, all of my iCal events would sync flawlessly. But none of the events I've created in iCal (Calendars) since upgrading have synced to the iPhone. Likewise, no new events that I create on the iPhone Calendar will sync to iCal. Also, changes to an existing event (even one created before upgrading to Mountain Lion) don't get synced either.
    Everything else seems to be syncing just fine though (music, apps, contacts, etc).

  • Google Talk not working with Messages after upgrade to Mountain Lion

    After upgrading to Mountain Lion, I'm no longer able to use Google Talk with the new Messages App.  It worked fine on iChat, but now I cannot enable the account.  When I try to check the enable box, it immediately unchecks itself and nothing happens.  Any suggestions?

  • Problems with apps since upgrading to Mountain Lion

    Since upgrading to Mountain Lion, I get the message "Application Not Responding" for several apps (Quark 9, CS5 apps, and Word for Mac) after they've been sitting open and not being used for a couple of hours. I have to "Force Quit", then restart the program. Not sure what's going on. Didn't have this problem with Lion. Any suggestions on what I can do to fix this?

    OK, I updated Quark 9, CS5 apps & Word for Mac. Quark 9 and InDesign are still giving me "Application Not Responding" after being open and unused for a few hours. The other apps are now working fine...Photoshop, Illustrator, Adobe Bridge and Word for Mac. Any suggestions for what I should do about Quark and InDesign?

  • Mail sorting problem after upgrading to Mountain Lion?

    I have a strange problem with Mail after upgrading to Mountain Lion.
    Before upgrading, when I tried to search my Mail Inbox for e-mails from a specific sender, the esearch results would be indexed by the name of the sender. For example: when I entered 'John Smith' in the search box in Mail, it would display a list of email from 'John Smith'
    Now after upgrading, the same query indexes the search results by the 'To' address i.e. my email address.For example: if my name is 'Steve Johnson', a search for 'John Smith' in the search box in Mail displays a list of email to 'Steve Johnson' and not from 'John Smith' which is how it used to display before.
    My emails are sorted by Date always, and I am using the default Mail view [not classic view]
    Can someone please help with a fix for this to help me get back to the original display I had while searching? Thanks in advance.

    I'm having the same problem.  It's incredibly annoying!!!  Did you find an answer?

  • After upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues

    after upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues. my computer now freezes and programs close randomly. The usual command for opening windows with bootcamp doesnt work. once in restarted my computer after it froze and it rebooted in windows automatically. i really just want to know if there is a way to take the upgrade off my laptop because it is very annoying.

    Hi Memalyn
    Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
    My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
    If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
    Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
    Let us know what you find out, and if you manage to get your space back.

  • Dashboard widget with streaming video breaks after upgrade to Mountain Lion

    Hi.  I recently upgraded from Snow Leopard to Mountain Lion.  Under SL, I had an OS X widget that was a web clipping of a streaming mpeg image being produced by a Linksys/Cisco WVC54GCA web camera.  When I brought up the dashboard, the OS would start streaming the data from the mpeg filename, which looks like "hostname.com/img/video.mjpeg". 
    After upgrading to Mountain Lion, I noted that the widget never fully loads, indefinitely displaying a "Loading Clip..." mesasge.  After deleting and re-adding, I can still get as far as adding the web clipping to the dashboard at the right dimensions, but there's no content.
    Unfortunately the camera unit doesn't provide for the display of HTTP access logs, so I can't see if there's an issue there, but my understanding is that if I can display the image in a Safari browser, it should work just fine in Dashboard too.  (I did make sure that, where needed, the username/password for accessing the video are included in the URL.) 
    I did sniff the network traffic between my system and the camera host, and show that video traffic starts flowing between the two as soon as the widget is brought up.  So, it's almost like the widget doesn't know when to stop "loading" and start "displaying," perhaps because the HTTP request is never truly "done."
    Can anyone speculate if something may have changed in Mountain Lion affecting the ability of web clipping widgets to display streaming video?
    Thanks,
    Chris

    Hi James
    I have exactly the same problem with the same "Loading clip" then blank.  I have been trying a lot of stuff to get this working, but haven't had the chance of sniffing the network traffic as you have done.  By reading what you said about the traffic seems to be flowing without the picure being displayed makes me even more puzzled by this.  I never had a streaming video while  I were using Snow Leopard, but I had a still-image, as I also do now in Mountain Lion.  I recently began to research for a way to display the video.cgi MIME image that my camera produces, and I've also concluded that this should be an easy task for the dashboard web clip function; the video does display in safari after all.
    I suspect that our cameras uses the same built in webserver solution written by a "Steven Wu".  Cheap webcameras frequently uses his script with MJPEG (stream of JPEG pictures) to avoid the expensive licenses of using other video codecs.
    I read this a bit down at this site: http://channel9.msdn.com/coding4fun/articles/Everyone-Loves-Babies-Webcams-and-M otion-Detection
    Have you come any closer in your research?
    I have started to think that maybe I have to write a dashboard widget on my own to accomplish this.

  • How to correct battery drainage problem after upgrade to mountain lion

    My macbook pro battery drains very fast, just used 3% as I am entering this question. This rapid battery drain started after upgrade to mountain lion. Any advice?

    This appears to be a problem that's affecting a number of users and has been widely reported. My guess is you're going to have to wait till they do a software update.
    There's general tips for conserving battery power on my page here that might ameliorate matters in the meantime:

  • Mail problems, slow browsing and Facebook problems after upgrading to Mountain Lion

    Hi !
    I have a 27” iMac from late 2009 which started acting really strange after upgrading to Mountain Lion.
    Before that everything works fine but now Mail does not work, will not send replies or add attachments and browsing has become so slow that it usually times out. Another strange problem is Facebook messages which does not work at all (cannot read nor send(.
    I have Lenovo laptop connected to the same network so I can benchmark and browsing works just fine on that aswell as FB messages.
    Anybody got a solution to this other than using the iMac for offline use only ?

    Hi !
    I booted both the modem and router but it did not help. Then I tried using the iMac on wireless and now it works so must be something in my D-Link router.
    Thanks for pointing me to the right direction !

  • With Lion I had 2 user accounts. Why do I have three user accounts after upgrading to Mountain Lion?

    I had consistenlty had a master admin user account for myself under Lion, plus the "Guest" account recommended and created by Lion. After upgrading to Mountain Lion, I now have the same 2 accounts, plus a new one called "Other." Why do I have that? Why was it created? How do I get rid of it if it is not needed?

  • Connection issues after upgrade to Mountain Lion

    Very strange internet connection problem here after upgrade to Mountain Lion.
    I just upgraded MacBook (early 2009) to Mountain Lion. After upgrade, I'm having problems connecting to certain websites (ESPN, CNN, etc.), and I can't connect to the computer using LogMeIn.
    BUT, I do have an internet connection. Skype works, Messages works, email works, some websites work. I tested using speedtest.net and it shows good download speed, but the upload speed is so slow that it can't even perform the test. A Windows PC on the same network works fine.
    Next, I tested the MacBook on another wi-fi network at a coffee house, and everything works fine there!
    So it might appear to be something wrong with the router? I have an Cisco (Linksys) E3200 and have upgraded to the latest firmware (1.0.4). But still doesn't work.
    The firewall in Mountain Lion is turned off, and I temporarily turned off the firewall on the router and that didn't help, so doesn't appear to be any sort of firewall issue. I've never heard of an operating system being incompatible with a specific router anyway.
    Can anyone thing of any setting or something in Mountain Lion that would causing internet connection problems with a specific router?

    I don't know if this will 'fix' your problem, but have you tried the 10.8.5 Supplemental Update -> http://support.apple.com/kb/DL1686?

  • After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occasionally lock-ups.

    After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occassionaly locks up while using Safari, Mail or Dreamweaver and I have to d a force-quit, then restart my Mac.  Anybody having similar probelms?
    I am thinking about doing a clean install of Mountain Lion.  Would I be able to restore my applications and data from Time Machine after the re-install?

    My 24 inch iMac... 2.8 GHZ dual core (Early 2008) is having the same problem.  After it sleeps, I go to use something... and the beachball of death occurs.  This happens multiple times a day... and let me tell you... it is annoying... and I am the one who is being annoyed!
    It could possibly be revolving around safari... as that is really the only thing that is running consistently.  I don't use iTunes on this iMac as I have so many other Macs up and running in the house... and I never consume media on it... so I kind of dismiss iTunes being the culprit.
    This is majorly affecting my Mac... in terms of reliability and uptime... which coincedently is the main reason why I switched to Mac in 2008.  This is my only Mac that could upgrade to ML... so I don't know how widespread this is... but I hope that this problem can be solved...
    I agree with another person who commented on this issue... do we really need a 10.8.1 update already... to fix this?

  • After upgrading to Mountain Lion, I repurchased Garageband and I can't get passed the complete installation. I don't seem to have the "com.apple.garageband.plist" file that has been a common solution. Any suggestions?

    After upgrading to Mountain Lion, I repurchased Garageband and I can't get passed the complete installation. I've read through several posts that all reference the "com.apple.garageband.plist" solution. I don't seem to have the referenced .plist. Any solutions or suggestions?

    Did you upgrade from SnowLeopard?
    I can't get passed the complete installation
    What exactly is happening? Is GarageBand trying to download over and over again?
    all reference the "com.apple.garageband.plist" solution. I don't seem to have the referenced .plist.
    The property list stores your preferences, but also the settings from the last run of the application.  If that file is corrupted in some way, you might see third behaviour.
    You must have this file, for it will be recreated automatically, if it is missing, or you have a permissions problem with your user library.
    Perhaps you did look in he wrong place.
    in MacOS 10.7. or later the User Library is hidden. To find the Preferences Files use the Finder's "Go" menu:
    Quit GarageBand, if it is running.
    Click onto you Desktop to bring the Finder forward.
    In the Finder Menu press "Go" and hold down the "option/alt" key, until your user library appears in the drop-down menu
    Select "Library" and in the Finder window that opens navigate to the "Prederences" folder; move com.apple.garageband.plist to the Desktop.
    Log off and on again (don't skip that step!). Retry GarageBand and see if it GarageBand is now downloading the missing content properly.
    If that does not fix the problem, post back and explain in more detail what the download problem is.
    Why did you "repurchase" GarageBand? If you already owned GarageBand '11, it should be unnecessary.
    Regards
    Léonie
