MacBook Pro freezes when battery powerd. Help pls

Hello There.
I have noticed that, when in battery power and Itunes open, my Mac freezes.
I have read some of the threads regarding wifi, but in my case I am 100% sure it only occurs on Battery power.
Please help me out
Itunes 7.3.1

Hey,
I am a new Mac user myself and have had the MBP for about 10 days now. Today my computer froze on me about 7 times. I have figured that everytime it freezes is when it is on Battery Power. I never seem to have this problem on mag safe.
I encounter this problem with iTunes for sure and also when browsing the web.
I have reset PRAM
Utility Disk Repair
Still freezes
I serve in the Airforce and live in Europe so any help would be great.

Macbook Pro Freezes When USB Plugged In

Just like the title says, my Mid 2012 Macbook Pro 13 running 10.8.2 freezes for an averge of 15 seconds whenever I plug anything into the USB ports. It varies depending on what is plugged in. Phones, both iPhone and Android make it freeze for about 15 seconds, USB drives are usually just a couple seconds. I dont even know where to begin when trouble shooting this. Any ideas? Thanks in advance.

Hi guys,
I have the same problem with my MacBook Pro. When I plug in any usb device I get a short freeze of the pc for about 5 seconds. During my tests, I noticed that the freezing starts from the first time that i move the touchpad. It means that if I plug the usb device and I move the touchpad after 30 seconds, I get the freazing from that time for 5 seconds. if I continue to move the touchpad while I plug in the usb I don't get any freeze. Moreover, I noticed that if in the meantime that I plug in the usb I move the touchpad without any interruption, I don't get any freezing.
I don't know if the problem could be related to the touchpad or not... Help!!!

MacBook Pro Freezes When Viewing Any Video with new iTunes

I, too, am having problems with the latest iTunes update. My MacBook Pro freezes completely. Total lock-up. This happens when trying to view any video, including video podcasts. I have to hold down the power button for several seconds to get my laptop to turn off. Any other MBP users experiencing this?

Hi there, I have the same problem as you guys, everything was fine before iTunes 7.6 or iTunes 7.6.1 I tried both, before those updates I could watch any video in iTunes without any issue, after that when I play a video, a random video my Macbook freeze totally, sometimes comes alive but 90% of the cases I have to make a hard shutdown (press and hold the power button). I can't believe this kind of bugs in a software that is so mature. Help please!

MacBook Pro freezes when trying to shutdown

My macbook pro freezes and the screen turns blank when i try to turn it off. instead i have to hold down the power button and get the "mac os x shut down or something" message. it happens randomly and i cant figure out what to do. i have tried all of the restarts and have done a virus scan, although i know macs dont get viruses. any help?
2.2 GHz, 2 GB, 128 Video RAM, 15in Leopard, Intel Core 2 Duo

Please post the specs of your macbook pro including hard drive size and amount of free space, graphics card, and installed RAM. This will help folks help you.

Macbook Pro freezes when i'm on the internet, help!

When i'm on the internet, on facebook or youtube sometimes my mac takes forever to load or doesn't end up loading the webpage. When this happens I just restart my laptop. Is there something wrong with my mac? Is there anyway I could fix this problem myself? I just got my mac only 2 to 3 weeks ago so I'd hate to have to already exchange or repair my macbook pro laptop.

Before you embark on Carolyn's 'nuclear solution' just try my suggestion first. If your Mac then works:
Repairing permissions is important, and should always be carried out both before and after any software installation or update.
Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
In First Aid, click on Repair Permissions.
This only takes a minute or two in Tiger, but longer in Leopard.

An article on troubleshooting Permissions can be found here:
http://support.apple.com/kb/HT2963
If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
Once that is complete reboot again from your usual start-up disk.

Macbook Pro freezes when pressure put on bottom right corner

Hello all,
I have a mid 2012 macbook pro. Sometimes when I pick up and move my laptop the computer will freeze and black horizontal bars will come across the screen, and I will need to force shut it down to be able to the use the computer again. The more confusing and helpful symptom I have noticed is when I put any sort of pressure on the bottom left corner of the macbook (below the keyboard, to the left of the trackpad) which aligns to be over the battery, the computer will immediately freeze and the black bars will come across the screen. I took it in to a repair shop and they replaced the hard drive and RAM, neither of which helped the problem, but both were corrupted so needed to be replaced anyways. Upon further inspection, nothing else seemed out of the ordinary. Has anyone else had the same problem or know any possible causes/fixes?

Please make a Genius Appointment and take it in for service.

Macbook Pro freezes when I unplug USB hub

When I unplug my USB hub from my Macbook Pro it freezes up and I have to turn it off and back on. I did not have this problem before, it just starting happening recently. The only thing plugged into the hub at the moment is my keyboard which has the wireless reciever for my mouse plugged into it. Any solutions would be greatly appreciated as this makes it a hassle to take my Macbook anywhere.
The USB hub is Gigaware brand, my keyboard is Apple, and my mouse is a Logitech MX Revolution, if that helps. I also have a LaCie 1tb external hard drive plugged in but that's using the firewire 800 slot so I wouldn't think that would affect it.

I have a somewhat similar problem with my Macbook Pro and USB hub - it just started happening last week as well. I have a USB (external power) hub that hooks to an audio interface, piano keyboard, wireless keyboard and mouse. I normally have my laptop off when I hook up the hub because I've been traveling. Last week I plugged it in while the computer was on and the hub froze. I turned off the computer and unplugged everything. I turned everything back on and the hub worked...for a few minutes. Now anytime I run any type of audio or video from the computer (itunes, LogicPro, internet video) the hub freezes as soon as I press play. Then the program (like Itunes) freezes and I have to force quit. This makes me wonder if it is not the hub but something that the computer is using to run audio and video. None of my external equipment has caused problems for a year now - there is no new equipment - and just the standard Mac software updates.

Macbook Pro freezes when I plug in USB

I've not changed anything about my Macbook Pro (13" early 2011) except upgrade to Mountain Lion (10.8.2) and now when I plug in my USB hub (which only has my keyboard, mouse and printer connected to it) the computer freezes completely and I have to press and hold the power button to restart it. If it doesn't do that, then it just doesn't recognise that the USB has been plugged in at all.
Is this an issue with the USB port or something else? I still have AppleCare so will take it to an Apple Store if I can't find out how to solve this problem myself. Anyone had this issue and found a solution?
Thanks.

Did you also try this when booted to the Recovery HD volume? If not then give this a try. In addition, while troubleshooting unplug all USB devices (includeing the keyboard) and try with another device such as only the mouse, which should allow you to move the cursor on screen. What you've done so far is only half of the picture, and doing this with the mouse both in normal boot and when booted to the Recovery HD partition would help determine what the problem is.
It is sounding like the issue is not with the printer and instead is with your computer, so hopefully its just a software configuration snafu, but it could be a problem with hardware.
If you find the mouse will not properly work in any port when booted to the Recovery HD partition, then run the Apple Hardware Test suite (see here: http://reviews.cnet.com/8301-13727_7-57352461-263/how-to-invoke-and-interpret-th e-apple-hardware-tests/, but do not run the "extended" test) and see if they bring up any problems. If so then write them down and post what they are here.

Macbook pro freezes when open finder

Hi, I have a problem with my macbook pro, since mountain lion os 10.8.2 update, every time I open the Finder freezes and I have to shut down my macbook with the button, because it does nothing, it only happens when I open the finder , which may be the problem?

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

MacBook Pro freezes when open Adobe products

I use my MacBook Pro connect to an iMac in Target Display Mode, everything works perfect. When i use my Macbook standalone (not connected to iMac) and open Adobe products it freezes and have to restart. Why does does this happen yet when connected to the iMac it is fine (never freezes, ever!)

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Note the timestamps of the BOOT_TIME log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Some private information, such as your name, may appear in the log. Anonymize before posting.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". A shutdown stall report has a name that ends in ".shutdownstall". Select the most recent of each, if any. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot. It's possible that none of these reports exists.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

Brand New MacBook Pro Freezes When Playing Games

My sister recently received a brand new MacBook Pro courtesy of the University of Arizona and already she is having problems. When my sister plays a Java based game utilizing the Open Gl graphics plugin her computer will sometimes freeze after the graphics become distorted. during the freeze only the mouse will move and everything else is unresponsive, the only solution is to shut of the computer using the power button. All the updates have been installed and this doesn't happen any other time then when playing that game. This neither happens on her PC nor does it mine playing the same game. I'm not sure what the problem is and I would appreciate any help.

Is this Java based game Runescape? I experience the same crashes, ive tried using other things in-game other than the OpenGl and i still experience crashes, much more often when i have iTunes running while trying to play. Ive never had problems like this before, even while using older computers with much less memory, etc.. This is my first mac and id have to say it's not leaving a good impression. I planned to be able to play some games on this and consider Runescape requires very low CPU this is kind of sad that a Mac can't process it without crashing. Ive been reading lots of similar posts online and it sounds like Apple should be worried more about customer satisfaction than their own stocks. Hope something works out soon!!

Macbook pro freezes when I perform a soft reset. The only option is for me to hard restart it to get it working again.

Hey everyone, I've been searching for quite awhile for an answer to this issue, and I haven't found it - so I figured I would post a question about it. To give some details, whenever I soft restart my Macbook Pro (By resetting it through the "restart" option at the top left) it will shut down to a gray screen and just sit there forever. The only thing I can do, as far as I know, is a hard restart - by holding down the power button and shutting it down - I know this isn't good for it, but again, it's about the only option I've got.
I've tried to verify/repair my disk permissions, and that hasn't helped.
I've also not installed any software since before that started happening. I'm also using OS 10.8.2 - I don't remember what was installed prior to that though - but it's an early 2011 model...the problem actually started happening well before I updated to Mountain Lion, and it's still happening now.
Thanks!
