Hello, I have a problem with my mac book pro after running the battery dead on a game. The display has shrunk leaving two black margins on either side. What to do ?
Go to System Preferences>Displays and set the resolution to "Best for this computer" (or something to that effect).

I have problem shutting down mac book pro os x lion
I have setup os x lion on my mac book pro which i bought after 2010. Over 90% when i want to shut down, the process stop at the end and rounding circle appear for so long that i should turn off the system by pressing and holding power bottom. I do verify and repair the disk permission and for a while it is ok and after some times it is the same story. I even download and install the lion again but nothing happened. As i read over the apple forum some other has the same prob but no one knows how to fix. Smebody tells that it is belong to safari and other mention some other things. Pls kindlly help me.

I am wondering if your hard drive is failing? You might try downloading and running SMART Utility on it:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It is somewhat more critical than Disk Utility, and may give you earlier warning of impending drive failure.
You might also want to run the extended version of the Apple Hardware test and see if you get any error codes.
From the way your hard drive is behaving, it sounds to me like there is something wrong with it. Since reinstalling the OS doesn't solve anything, you are likely dealing with some sort of a hardware issue.
Good luck! -

I have problems with my Mac Book Pro after I upgraded it
I upgraded my Mac Book Pro from MAC OS X 10.9 to Yosemite version a week ago, and now it doesn´t start
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -

Problems with new Mac Book Pro 13'' +power adaptor
Hi there,
I'm new here and first of all I'd like to appologize from my lack of technical language, since my only interesst in computers is that they don't give me problems so I can keep not knowing too much about them.
Ok, so I bought the new Mac Book Pro 13'' exactly 2 months ago cause my old and long travelled Power Book G4 died. I didn't hesitate to spend the money to buy the new one, cause I was so happy with my experience with the old one and in my mind returning to PCs was not even considered.
BUT...I'm not totally happy about my new laptop...from day 1 Safari would just close itself but I didn't give too much thought about it. After this, not only Safari can close up to several times a day, but also iphoto or any other program that I use for work. But that's not all..One day it would take minutes to start running and it would go extremely slow...another day it would start also very slow but also it wouldn't show the tools bar on top or my folders. Another time it would show me, instead of the normal starting page, a page where it would ask me to accept or not a kind of revision for hardware. After so many problems of course I pressed yes...everything seemed normal, then computer started and seemed to be running normal again (aside from this safari and other programs that shut down). Today my computer, when moved, just went totally blank but fortunately I could start it with nor problems after it.
So...anyone knows what the problem must be?? Should I take it to a Technical service ??? and there's another issue...i'm handing in m phD in a week so I can't just be without computer now, and in a week I'm flying to Canada where I also will need my computer for work...what can I do???
And the second problem...the power adaptor from the beginning seemed to act funny sometimes...sometimes charching, sometimes not, I would follow the instructions in the support part and after being several minutes changing one cord for the other, to keep it 1 minute disconnected and so at some point it would start functioning again. But this happened seldom so also I would think it was a protectiion mechanism of the adapter. But, when this is happening more often than not, then it gets annoying. Also I've been transporting it in a careful way since I bought it to find that after only 2 months in the cord (from the computer to adaptor) you can see the internal cable as if there was some cut...a third one seems to be appearing too. I've taken it to the technical support and the guy who was helfpul but also honest said he couldn't do anything for me cause since there were those cuts, he could always be said that it was a misuse of it-an accident and then he would have to pay the replace himself. Well, it's not!!! My old adaptor has been transported in a way less careful way and it's survived with NO problems for 5 years. The material is clearly different from the old cord. This one because it's new, I only need to put it in a special bag air protected. Honestly I don't feel happy to pay 80 € for an adaptor that I don't know if it's gonna last me only 2 months or that I know I can't transport normally. The guy suggested me to ask in forums and to call directly to the apple technical service.
Again, has anyone had any similar problems with the adaptor???
RosannaTake it to an Apple retailer and have the computer repaired. It is still in warranty.

A while back I had an upgrade available to me. I had Lion when I bought this Pro. The upgrade is Maverick. After downloading and installing the upgrade, my computer started freezing while doing anything. I might not get this completely written before it freezes. The keyboard is getting hot, and I have to use the power button to turn it off. After it has sat for at least 10 minutes, I can turn it back on. I might be able to do some work for 5 minutes, or up to 30 minutes before it freezes again. Some of my programs are not working, either.
I would appreciate any suggestions anyone might have, or even go back to Lion, if I can figure out how to.
Thanks.Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test. -
Hi iv been having this problem for a few months now my mac it keeps on freezing. the curser works but stays on the loading one (the rainbow circle) other than that not much els dose.
at the time that this started i was on skype having a video chat and my mac turned it self off and wouldn't come back on for a bit but eventually did come on but it began to freeze
when i give up waiting for it to unfreeze (about 10 -20 min) and turn it off and back on then i have one of 3 things happen.
1. it turns back on and works for a bit (from 2 min up to 1 hour)
2. it wont go pass the loading screen and i have to reinstall the os (which some time frezes on me when i am installing it. also some times the hard-drive or dater disk keep on diserpering off of the mac but 9 times out of 10 i can get them back on through the disk utility)
3. when reinstalling the hard-drive appears to have lost the os previously installed with out me erasing it and requires me to in stall it (but i have had it freeze during installation which i have to turn the mac off and back on and it come on as usual with all the info there from the last time)
the las time i had to do this i used the disk utility and erased the hard drive and data disk using the 35-pass erase of deleted files but hasn't stopped it as time has gone on with it it seems that it has been improving recently it has stayed on for 15 hours before having to have the os reinstalled.
any ideas what wrong with my mac ?

how do you free up disk space on macbook pro 2013 model to upgrade and update software
Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Also see Freeing space on your Mac OS X startup disk.
5. See Where did my Disk Space go?.
6. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located. -

I have a very irritating problem with my MacBook Pro. It keeps loosing the wifi connection - every 5-1o minutes!!!
I have testet the wifi signal and had my router checked - both are fine.
Please tell me what I can do :-(
JohnFirst you should check on another Wifi to see if it's your Lion machine.
If it only occurs on your Wifi, then perhaps you have local interference and need to set the router on another channel far from others.
You can install a free program called KisMAC that you set your Driver Preferences to Apple Airport Extreme Passive Mode, enter your Admin password and monitor your local Wifi signals, see if you cna pin point the cause of your interference or meddler.
If your not running WPA2 with AES and a 12 plus random character/letter/number password for both Admin and Internet access use only then you should seriously consider doing so.
