Mac book pro, mountain lion screen flickers. Any solution?

Hi
Suddenly the screen of my mac book pro started flickering. I have no idea what's going on. Tried couple of tricks (re-setting the EPRAM...), but nothing works. Any help?
thanks

You should also ask this in the MacBook Pro forum. This is the forum for the 13” white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

Frequent Panic Attacks for my Mac Book Pro Mountain Lion 10.8.5

Hi All,
My mac book pro with OSX mountain lion 10.8.5 has kernel panic attacks randomly couple of times a day.
I have no idea why or when it gets trigerred. I dont have any third party drivers or extensions installed (except for upgrading to 16gigs of memory).
I have already reimaged my hard-disk ( took a apple genius appointment and they did it for me).
But issue persists after that.
Can anyone look at the panic report below and tell me what the issue could be ?

Yes, your MBP should support Mountain Lion. See this Apple note.

2012 Retina Mac Book Pro (Mountain Lion) crashes while using Finder

I used the Migration Assistant to move over my settings and file from a 2009 Mac Book Pro to a brand new Retina version. Everything was working well until, on the first day, I needed to use the finder to search for photo files on the hard drive. I am updated to the moset current OS X 10.8.2. My old computer was not giving me this problem. I have used to disc utility to check and repair permission. It doesn't matter if I have ten applications open and running or none. It only crashes while searching in the Finder while using the space bar to preview. Thanks for any help on this!

Question about Formatting Buffalo USB 1TB external drive for use with Mac Book Pro Mountain Lion HD

Hi there, Have Mountain Lion HD operating system (not sure if it is 10.8 or 10.8.1. or 10.8.2) and have a Buffalo USB 3.0 1TB hard drive. When go to utilities to try and format with Mac OS extended, following 3 files show. DriveNavi. exe, Slm.exe and Mac. The option to left click and erase menu is not there. Or at least not as shown in all the help videos.
It is USB connection so will take ages but want to use drive to store video footage and also partition to back up Time Machine. ( travelling in South America and no other Ext Drive option available too buy) how much space should i assign to Time Machine when partitioning? Is there anything else i need to think about? as new to formatting. Any thing else i can do to make process of transfering footage to Buffalo quicker?
Final question is if it is finally reformatted am i going to have to spend so long accessing footage from hard drive when back home and editing that it really is not worth if, and i should just write this off as an inappropriate purchase, and try and buy more memory cards and not bother with transfering/storing? Thanks in advance for time spent trying to assist.

Use Apple's Disk Utility in the Applications/Utilities folder to format the drive.
The programs on the drive given to you by the manufacturer is likely backup software (or malware) and essentially worthless, it will be wiped when you format the drive.
I do NOT advise you partition that drive for TimeMachine, rather I advise you not to use TimeMachine at all for your purposes because TM is just a backup, not a bootable drive.
Rather do this.
Get another hard drive that is equal to or slightly larger than your boot drive.
Format the drive in Disk Utiltiy > 1 Partition, option: GUID, Format: OS X Extended journaled, click Erase and move the slider one spot to the right and click Erase. This will take some time as it's going to map off any failing sectors it can BEFORE you lay data on the drive corrupting it.
Next, pay for and download Carbon Copy Cloner, use the default settings and simply clone internal drive to the external drive. this will also take some time the first time.
Next use Disk Utility to Repair Permisisons on both drive. Now reboot the machine and hold the option key down, you can select the external drive clone to boot from!!
You can update the clone the same way by using CCC, but it doesn't take as long, only copying changes.
This is better than TimeMachine as a bootable clone is bootable in case your internal drive fails to boot the machine.
Use the first drive for storage and be very gentle with it while it running, like you should do for all hard drives as they are subjective to shock damage.
The objective with the clone drive is you keep it safe, and not carting it around where it can be more subjective to damage like the other drive will be.
Remmeber you need 2 forms of hardware backup at all times.

Reinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

How can i get my nikon software to work on my new mac book pro with lion

i had nikon software (capture nx2 and view nx) on my old imac that ran leopard
i cannot get my nikon software to install on my new mac book pro with lion
can anyone help me get my software installed
i need this software to work immediately because without it i am unable to work that is the programs on how i process my photographs and without it i cannot make any money
thank you

That seems to be supported only up through 10.5.7 and probably needs Rosetta for it to run.
Rosetta is not included in 10.7.
If this is the case, you may need to partition your hard drive, install Windows on it, and use that partition for your work.

I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this?

I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this? It bugs me when I'm looking at real estate.

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

Mac book pro with lion very sluggish

I have a mac book pro running lion 10.7.5 with 8GB of RAM; last few months has be come very sluggish. Any clean up or other things i can do to restore to orignial performance?

Clone backup your data to two separate locations, then we can look at why.

Using multiple desktops with a 4 finger swipe on a Mac Book Pro running Lion- is there a way that I can allow Safari open on several but not all?? Looks like I can set it for one but not others. All, one, or nothing

Hey Eric,
Thanks for taking the time. Unfortunately no that does not solve it. Same as swipe it will get me there and it will show separate programs spaced out. The issue I am having is that all my open word files are bunched up in a pile on top of each other. I can see the edges of each one but I want them to be separated from each other enough that I can visually identify what file is what.
Again, thanks for trying, it is appreciated.
