My Macbook screen flickers since installing Lion

Ever since I installed Lion on my Early Model Macbook, the screen flickers intermittently.
It doesnt go completely black, its as if the screen is tryng to go into low power mode and back out again really quickly.

Well I think I found a solution, you can try the Energy Saver settings and deselect "Automatically reduce brightness before display goes to sleep', so far I haven't had any problems with my screen.
Hope this will solve your problem too.

  • 15 inch Mid-2010 MacBook Pro freezing since installing Lion

    I've had this problem for a while now. It started a few weeks after I installed Lion in the summer. My MacBook Pro would just freeze without warning and the only thing I can do is a force shutdown. I've checked the logs, and these freezes do not log themselves like other crashes, there is no record of them happening. I have also noticed that Apple has identified that my particular model of MacBook Pro can experience an issue where it may freeze intermittently or stop displaying video, and as such they put out an update to help remedy this, which I have installed and the problem still exists.
    The freeze appears to happen application by application. One application may freeze, so I attempt to force quit this, but then the force quit window freezes, and then whatever else I click results in a spinning wheel, forcing me to hold down the power button to restart my Mac. I never had this issue with Snow Leopard, it has only started since I upgraded to Lion.
    I have taken it into an Apple store, and they could not indentify any issues since there were no logs of the crashes. They wiped my laptop and suggested I try using it for a while without any of my data on it to see if the freezes still happened - they didn't. He then said not to restore my data from a Time Machine backup as any bugs that may be causing these freezes would also be restored. Therefore, I installed every application manually and only copied over my documents and music manually. For a few months, this fixed the issue, but I have noticed that it has started happening again, more and more frequently just like before.
    I've also run the Apple Hardware Test that came with my Mac and it found no issues. I've also reset the SMC and PRAM to no avail.
    My specs are:
    2.4GHz Intel Core i5
    8GB RAM
    500GB HDD
    Lion 10.7.3
    If anyone has any suggestions on how to fix this issue or knows why it is happening, please let me know, I would greatly appreciate it.
    Apologies for the long description, I wanted to be a detailed as possible.
    Thanks,
    Nathan

  • Very erratic behaviour since installing Lion - where do I start

    Since installing Lion a few weeks ago on my Macmini I've have a couple of issues which are bugging (no pun intended) the life out of me. I'm almost at the point of doing a complete erase and install of Lion it's that bad. Normally I always do an erase and install when upgrading OSX but the setup of my mini is such that it would take me a long time to rebuild it from scratch. That'll teach me.. I just upgraded Lion on top of Snow Leopeard, whereas on my MBP I did a clean install of Lion and no problems.
    Here are the issues on my mini:
    1) In the past couple of days I've had a couple of kernal panics "You need to restart your computer..." I've never had this before on any of my Mac's. The only thing that has changed on my system is that I've updated a driver for my WD MyBook drive, which I use as my TM backup. Since upgrading to Lion I switched off time machine and only turned this back on because I thought I'd reached a general steady state with my system and after installing the driver update. I've since disabled TM so fingers crossed no more problems..
    2) On serveral occasions, whilst using back to my mac, to screenshare my mini on my MBP, I've had windows and hard drives disappear off screen. If I do a right mouse click on my finder I can view the windows on screen but when I select them they disapear. I have a feeling that mission control is doing something, but I never use this, nor do I have anything set-up, other than the intial configuration. This is *really* doing my head in. I can usually fix it by changing the screen dimensions on my mini through the Display control panel or switching my TV over to the hdmi input so I can view the desktop directly on my TV (as opposed to screensharing).
    I'm not really sure if this is a problem with mission control, or back to my mac, or a video input problem (I'm using a mini displayport to dvi and dvi to hdmi cable to connect the mini to my TV).
    Any troubleshooting suggestions would be greatly appreciated, particulalry for issue 2.

  • Since installing lion my iMac and powebook can't find my printer

    since installing lion my iMac and macbook pro can't find my printer (it is on the supported devices list and I downloaded the latest drivers).
    I called canon and they stepped me through reseting my print system and reinstalling the print drivers and libraries but I have tried direct USB and via airport and the computers dont recognise the printer anymore. Just to be sure it was not the printer I tried to print from my iphone and that works...
    I have changed the usb cable, changed usb ports and nothing can get the computers to recognise the device. Please help all advice welcome!

    :-) here's an interesting link http://support.apple.com/kb/HT3669#canon
    Note: If you've haven't used Software Update recently on your Mac, please run it before connecting a printer or scanner to update your Mac's database on what software is available.
    I would also do this after you plug in your printer. Apple might have updates for your printer.
    there is Canon Software for lion. try uninstalling everything and starting from 0.
    http://www.usa.canon.com/cusa/consumer/products/printers_multifunction/office_al l_in_one_inkjet_printers/pixma_mx860#DriversAndSoftware
    I also read that if your printer shows up in your printer list before the appropriate drivers are installed, it might mess things up, if you plug in your printer and see it after cleaning everything you had done previously off, then try removing it from the printer list (don't just unplug it, delete the profile). And then install the appropriate drivers.

  • Why since installed Lion on my IMac it happened many times that my computer freeze and I have to restart everything before something work again?

    Why since installed Lion on my IMac it happened many times that my computer freeze and I have to restart everything before something work again?

    To get rid of "pop-up ads and other crap on my computer when I am on the internet", click on Safari in the Menu bar, and select Preferences. Next select Extensions. Delete all of them. Restart Safari.
    The first step in addressing the black screen is an SMC reset.
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

  • Pages '09 won't open Word documents since installing Lion

    Since installing Lion I can no longer open Word documents. I get the following window

  • Since installing Lion the desktop view occassionally jumps to 'grid' view when I turn the computer on.  Why?  It is set to manual in the view menu.

    Since installing Lion the desktop view occassionally jumps to 'grid' view when I turn the computer on.  Why?  It is set to manual in the view menu.

    Thanks for that information!
    I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
    In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
    When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
    Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?!

  • Trouble connecting since installing Lion

    Since installing Lion on my Macbook Pro, I'm having trouble acquiring and maintaining connections with my WiFi signal.  No such issues with my Snow Leopard/Leopard Macs, PCs, iPhone and iPad.
    Any ideas?
    Thanks,
    JD

    JD, I have experienced the same ... losing connection frequently ... what did it for me was to unplug my router (Time Capsule) and network extension (Apple Extreme) for about 15 minutes, then plug back in ... don't know if it will work for you, but it surely is worth trying I'd say

    Does that always happen after a certain amount of time?

  • Many years ago synced iCal with Microsoft program. Since installing Lion whenever I try to create an event in iCal it flashes up message "Unable to open Microsoft sync services Power PC applications no longer supported." How do I get rid of message?

    Many years ago synced iCal with Microsoft program. Since installing Lion whenever I try to create an event in iCal it flashes up message "Unable to open Microsoft sync services Power PC applications no longer supported." How do I get rid of message?

    Lion no longer supports PowerPC apps. If this is Microsoft Office 2008 (Entourage 2008) then you should disable the syncing services.  (I don't have Office 2008 installed anymore so I don't know exactly what it's called anymore.)  If you have Microsoft Office 2004 or earlier, then it can't be run on Lion at all since Lion removed Rosetta, which is what allowed a PPC app to run on an Intel based Mac.
    Also, I believe Microsoft removed sync services from the current Outlook 2011 (which replaces Entourage) so even upgrading to a newer version of Microsoft Office will not get you back that calendar sync feature.  Supposedly Microsoft is working on a new syncing system, but I wouldn't hold my breath.

    You're ignoring context.  On the old Apple Discussion Groups I never posted replies like that, instead giving people relatively detailed answers.  The new Apple Support Communities made things worse by introducing certain inefficiencies.  Then came Lion.  The flood of messages that came with Lion required a painful choice for any of the people who had been helping here: (1) Give quality responses to a few questions and ignore the rest.  (2) When applicable, give a brief answer such as the one that you found objectionable.  (3) Give up all the other normal activities of life and spend full time trying to answer questions here.
    People who needed help with Lion problems seemed to have trouble discovering existing message threads that described how to solve their problems.  I never posted the suggestion of "Check the 'More like this' area" without verifying that the help that the poster needed could be found there.  Even doing that, what I posted saved me time that I could use to help someone else.
    The people helping here are all volunteers.  None of them is being paid for the time they spend here.  They all have a life outside of Apple Support Communities.  It's arrogant of you to demand that people helping here spend more time than they already do.

  • Imac Intel freezin  & crashing since installing lion

    My late 2009 24" iMac has been freezin and crashing since installing lion. Sometimes red dots appear on the display and sometimes the image breaks up and then freezes. Happens in Safari, Photoshop, Word and other programs. Is it a NVIDIA driver issue? Is there a fix?

    I don't know if this helps, but OS X Lion has to re-index all of the files (correct me if I'm wrong), therefore, if you have just installed OS X Lion, you need to give it some time untill it has indexed all the files again (which could take a while if you have loads of files), after this it should return to normal.
    Otherwise, a clean install?

  • Weird keyboard quirks since installing Lion

    Ever since installing Lion, my keyboard has been acting weird.
    I can't quite figure out what's going on. So far, I've just discovered a few weird things, like:
    I can't use left shift to capitalize T, though it can capitalize every other letter, and I can capitalize it with right shift. What?
    Normally I use cmd-shift-[ or cmd-shift-] to switch through tabs in Google Chrome. I can't use the right cmd to activate this, and I can only use it to select the previous tab, with [. Also tried adding cmd-shift-] as a shortcut in sys prefs, but it won't accept it.
    The sys prefs F1-12 behavior preference is flipped from what it should be.
    I'm sure there will be more, but that's just what I've discovered so far. There are no hardware issues with any keys. Restarting doesn't help. I'm totally baffled.

    @willadler,
    Check to see if this issue is occuring system-wide by creating a test account (System Preferences > Users & Groups).  After creating a new account and logging in as that new user, does the issue still occur?  If so, then it might be a system-wide Login Item, so try Safe Boot to be sure, however, if the keyboard works fine in that new user account, then try the following:
    • Delete (or Move) the following files from your home folder:
    ~/Library/Preferences/com.apple.systempreferences.plist
    ~/Library/Preferences/com.apple.systempreferences.plist.lockfile
    ~/Library/Preferences/com.apple.universalaccess.plist
    ~/Library/Preferences/com.apple.universalaccess.plist.lockfile
    • Logout and log back in for the changes to take effect, and test the keyboard (NOTE: deleting the above files will reset much of the customizations you have made in System Preferences, so I'd recommend Moving them to the Desktop in case you need to restore them)
