Sleep Problems After Mountain Lion

I installed Mountain Lion on an Early 2009 iMac with 2.66 Ghz Intel and 4GB of RAM. I was upgrading from Lion. My computer is now ignoring my Energy settings, not going to sleep or dimming the display. What could be the problem?

Reselect and reset your Energy Saver Preferences.
Reset the SMC > Resetting the System Management Controller (SMC)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.

  • IMac powers off in sleep mode after Mountain Lion installation

    After I installed Mountain Lion on my 2010 iMac, it will power off after I don't use it a while. It used to just go to sleep, I'd shake the mouse, and it would come back up. Now it powers off and I have to power it back up every time. 
    My Macbook has NOT had this problem since Mountain Lion install. It is fine.

    Try doing a smc and pram reset.

  • Random sleep mode after Mountain Lion install

    Hello, I have a MacBook air 11" late 2011.
    after installing Mountain Lion I get random sleep modes, usually right after a waking up the computer.
    that has never happened before so I assume that it is a sotware issue.
    I do not have a hot corner for sleep (have checked)
    anybody else has the same problem

    It goes to sleep sometimes right after I wake up the computer ..
    wake up , 3-5 seconds .. I click somewhere.. it goes to sleep
    any downsides of resetting the PRAM and SMC

  • DNS problem after Mountain Lion upgrade

    Yesterday, I upgraded my Lion to Mountain Lion and after that I can't connect to websites or make use of services that use DNS. I've tried the regular 'solutions' that were posted in forums, but nothing has worked for me so far. Things I've tried:
    - Change MTU to 1300
    - Shut down Wifi and restart it
    - Reboot computer on several occasions
    - Change DNS servers
    - Remove Wifi network adapter and add a completely new profile
    - Flush DNS cache with the both the old command (pre-Lion) and the new command (post-Lion)
    - Install Mountain Lion again (after that, my sound doesn't work anymore either)
    - Stop mDNSResponder via Launchctl and start it again
    The only things I can think of next is to connect via LAN, connect via a different network or a complete clean install of Mountain Lion and see if that works.
    Symptoms:
    - Cannot connect to websites and services via URL
    - CAN connect to websites using their IP-addresses
    - Hence, Skype works as it connects using IP-addresses
    - Can use SSH
    - Have excellent connection within my own network at home (SSH, AFP file server, router web interface)
    Config:
    Late 2007 MBP 17"
    No VPN's
    No proxies
    Does anybody have any ideas what I can do to alleviate this problem or know of anybody else that has the same problem?

    Tried with different WAP and they all work fine except the one I have at home. Seems to be a problem between the new Mountain Lion drivers of my Airport card MBP model A1229 and the ZTE H220N wireless router.

  • Calendar problems after Mountain Lion upgrade

    Hello everyone,
    I've noticed various problems with Calendar after upgrading to Mountain Lion, but I can't seem to find my particular issue.
    After upgrading from Snow Leopard, here's the situation:
    *Every calendar that I had published has a triangle with an !, saying that the calendar couldn't be updated. This seems backwards, as they are not subscriptions--they are calendars I've created and maintained and published. They were shared using the iCalx webiste.
    *One such calendar, the one I use for myself (not the default one, but a separate one with my name) disappeared and seems to have moved into another calendar. I can rename it and make that useable.
    *All of the other above-mentioned calendars seem to be completely gone. No events or anything in them.
    *All of the calendars I'm subscribed to work fine, except for one from a coworker who also upgraded to Mountain Lion and is having similar issues. That one has an ! in a triangle, too, but I can at least see the events. Seems that that calendar just can't be refreshed.
    Any advice on what I can do to get me calendars back and correct this problem would be much appreciated.

  • Mail problems after mountain lion download

    I downloaded mountain lion and have now problems to send an eMail. Is there something to change!

    Look in System Preferences > Trackpad (or mouse) > Scroll & Zoom tab > uncheck Scroll direction: Natural.
    The scrolling direction has been changed to a technique where your push the screen up or pull it down, takes a few days to get used to.  The swipe directions will also be affected by this change.

  • Annoying Safari problem after Mountain Lion update...

    I've updated my Macbook Pro to Mountain Lion OS X a while ago and now use Safari 6.0 as my main browser. The zoom button (green button with the plus sign) on the top left corner doesn't seem to be working properly, though. Everytime I click on it, the browser's window immediately drops to the bottom of the screen. Might be just a problem with the settings...I've resetted the browser more than twice but the same annoying problem persists. Please help! Thanks.

    my understanding of the green + is : it is a toggle between the OS X default windows view for the application ( in this case Safari) and the users settings for the window. What probably happened some time when visiting a web page the web page resized your Safari window to be small and at the bottom of the screen. Hit the green + again and it should be a better viewable window.
    When the window is small and at the bottom move it up where you want it and make it the size that you want. Then the Green + will toggle between that view and the default view.

    I am getting the Kernal Panic after waking from sleep mode.  Also, I am getting this strange screen after logging in and right before the screen comes up (see attached image).

  • After Mountain Lion install, my iMac powers off instead of just going to sleep. Help? Thanks.

    Do these resets to clear errant commands:
    SMC RESET
    http://support.apple.com/kb/HT3964
    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    The 5 second timing is important to a successful reset.
    PRAM RESET
    Zap the PRAM
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • Problem with mail after mountain lion install

    Mail has become sluggish to locking up after Mountain Lion install.  I get the color wheel each time I start typing in an address to send an email.  I also get the wheel when i am typing an address or name in any web page in Safari.  Is this a Mail Problem or an Address Book problem?

    It sounds like your computer needs to be cleaned up. Have your repaired permissions or cleared caches since you got the computer. Often times when upgrading operating systems permissions get screwed up and it causes issues.  Go to disk utility in your "other" folder in applications.  Select disk utility, then on the left hand side choose Mac HD then click REPAIR permissions in the center section. Wait for it to finish, restart your computer, then test.

  • Some serious problems with Mountain Lion

    Hi everyone,
    I upgraded my mid 2010 15" MBP to Mountain Lion 2 days ago, and I have some serious problems with my machine now.
    - Wifi problem: like many members 's machines, mine has problem to connect to the wifi after sleep or restarting, I had to wait 10 to 15 minutes for it to connected to my home network. Anh I tried to remove all of my settings in System Preferences/Network and added new connection. And now it cant connect to wifi anymore. I'm writing this article while sitting on the floor with my Ethernet cable plugged in my MBP. I connected to internet through a DSL modem and a Airport Extreme as a bridge and Access Point. I also tried to set up all of my network device but my MBP can't connect to the wifi still.
    - Keyboard problem with Pages: I was very happy with the new iCloud syncing for Pages documents but after 5 minutes, I met a big problem with Mountain Lion. Whenever I type in Pages with Vietnames Keyboard( Mac OS X built in or from another developer: http://www.trankynam.com/gotv/ ), Pages stops working immediately. I can still drag the Pages's window around but can't type or do any editing. After that I have to force quit pages. It is really stupid that I'm writing a book in Pages and now I have to stop my working till apple fixes this ridiculous bug. I tried German Keyboard as well and Pages worked flawlessly. Do you hate Vietnamese, Apple?
    - Messages problem: Since upgrading to Mountain Lion I couln't send or receive any messages. It worked perfectly in Messages beta.
    Does anyone have the same problems like me? Any solution such as how to reinstall Messages(I googled but found nothing)
    Apple, please test your software more before release it. I feel like I have no computer at the moment because I can't work, can't surfing the web wirelessly and can't communicate with my friends.

    I found out that the problem with my wifi was my MBP received automatically a ridiculous IP such as 169.254.170.0 instead of 192.168.1.4 as it should be.
    WIll be part of the Issue as will be DNS issues.
    mDNSresponder crashed with Handsoff! v1.5.3. After upgrading Handsoff! to v2.0.2, it works again.
    In this case mDNSresponder also being stopped will stop DNS working.
    I would guess if you have resolved these that you can Chat to people again.

  • Slow internet after mountain lion download

    web pages open slowly or not at all after mountain lion download

    I'm having the same problem but only at home with a slow internet service.  At work with faster internet my macbook pro works fine.  I wonder if Mountain Lion requires some minimum internet speed?  Our old macbook pro (not using Mountain Lion) still works fine with our slow home internet.  This change happened when I installed Mountain Lion.  Also I can boot from by back up disk and bypass Mountain Lion and work with my slow internet at home. ???

  • After Mountain Lion download, FaceTime is not working anymore. Any ideas?

    After Mountain Lion download, FaceTime is not working anymore. Any ideas?

    I have reinstalled mountain Lion again . This time, Facetime works when somebody calls me, and I can do calls from my Mac again. But the problem was still that I was not able to call my iPad, what I was able to do with Lion (I had one Apple-ID and two call adresses). The solution was this time to generate a second Apple-ID from the Facetime in my Mac (this doesn't affect your main Apple-ID, it's only used for Facetime). Now, it works!  ;-)
