I tried remove battery, change hardrive, reset SMC still the same problem. Is here something like first help, or where could be problem.
Thanks
You could try a PRAM reset - not sure it will resolve the problem, but it won't hurt to try:

If the problem persists I'd recommend you call Apple and get them to look at it under warranty.
(P.S. no problems with your English - it's excellent )

GTA 4 on windows 7 BOOT camp texture problem, macbook pro 13 january 2011 help .

my problem looks like this

gta 4 steam !If GTA IV believes the system is under specification even though the computer is powerful enough to run the game with higher settings, the following will fix this problem.
This will work if your problem looks like this: "resource usage 230/60" and you can't change any other setting
Just follow the steps:
Step 1: Create a text file named ‘commandline.txt’ (without the " ")
Step 2: Put the following statement inside it:
i5 users: -availablevidmem 18.0 (with the -)
i7 users: -availablevidmem 22.0 (with the -)
Step 3: Open the main GTAIV folder (C/ program files (86)/ rockstar games/ GTA IV) and copy the commandline.txt file into it.
Step 4: locate the file "GTAIV.exe" (in GTA main folder)
Right click the file and select Properties
Under the shortcut tab, you will see an area that says Target
Modify the Target adding the command line after the last quotation mark (just add the statement you added in commandline.txt)
(remember, i5 users: -availablevidmem 18.0 / i7 users: -availablevidmem 22.0)
It should look something like this:
Make sure to add space between " and -"
I hope This helps, although late cx -
I am switching to Apple macbook pro from Windows laptop. Is Apple compatible with Microsoft Office? How can I transport from Windows to Mac? What I have saved on external hardrives, will I be able to open it on Mac?
Office for Mac, http://www.microsoft.com/mac/products, can open/edit/create Office documents.If your external drive is formatted NTFS then you can copy the Office documents to your computer and work on them. You won't be able to save the files back to your NTFS formatted drive. But you will be able to save the documents to your internal drive. You can move all the external files to your internal drive then format the external drive for Apple. Then you can copy the files back to your external drive for ongoing use.

I am switching to Apple macbook pro from Windows laptop. Is Apple compatible with Microsoft Office? How can I transport from Windows to Mac? What I have saved on external hardrives, will I be able to open it on Mac?
Is Apple compatible with Microsoft Office?
Any computer is compatible as long as it can read and write Office files. But for perfect (or at least near perfect) compatibility, you would want to purchase Office 2011 for Mac.
How can I transport from Windows to Mac?
You can't directly transport any installation of Windows. All PC's come with a machine specific version of Windows intended for that PC. They don't have all of the hardware drivers the retail disks cover.
If you want Windows on your Mac, you would first purchase a full version copy (NOT an upgrade disk) of Windows 7 or 8. Those are the only supported versions on newer Macs. You install it through the supplied Boot Camp utility that comes with the Mac to create a new partition for Windows, and then install the retail copy of Windows you purchased.
The reason only these versions of Windows are supported is the same basic reason as a machine specific version of Windows for a PC. Apple only includes the necessary Mac hardware drivers for Win 7 or 8 on new Macs.
Once Windows is installed, you could then install the version of Office for Windows you already own. The nuisance of a Boot Camp partition is that you have to physically boot to either Windows or OS X, so you can only use the apps of the OS you're in at the time. To use both at once, you'd have to use virtual machine software (Parallels, VMware, VirtualBox) and then install Windows within that. Then you'd be able to run Windows inside of OS X and have access to both at the same time. -
How do I switch users on wifi sync for example my Mac has two users one apples MacBook pro the other is my name I want to switch from apples MacBook pro to my name how is this done?
Try connecting the iPad to the computer that you do not want to WiFi sync with and uncheck the WiFi sync option in iTunes. Then click on Apply. Reboot the iPad and see if that does the trick.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. -
External Trackpad won't switch desktops on MacBook Pro
I have a 13-inch MacBook Pro and I recently purchased a standalone wireless keyboard and trackpad. The trackpad performs all of the gestures correctly, except for the four-finger swipe to switch between desktops. The built-in trackpad performs the four-finger swipe perfectly fine. I checked the System Preferences for the trackpad, but it looks like there's only one set of preferences for all trackpads.
My wife has a similar setup with her new iMac and she doesn't have the problem. Both trackpads switch desktops with a four-finger swipe. Weird, eh?
Any help would be greatly appreciated.I think that the issue might be that there is no boot0 in /usr/standalone/i386. I have had similar issues lately when trying to make a bootable usb memory. I think this is necessary for the legacy option in the bless utility. If some one have a solution for this I would like to know as well.

My MacBook Pro is exhibiting power problems. I am running Yosemite and it seems that the problem may have arisen since I dowloaded this upgrade. When the battery is charged it shows 99% charge and I can use it on battery power. As normal with use the charge gradually reduces, say to 30%. I then switch off using either the on/off button/apple logo, waiting for the dialogue box, " do you want to switch off etc". The next day, I switch on, but the computer will only boot up when the power lead is attached. When the computer comes on, usually as normal, the charge always shows 0%. When it is recharged the whole process repeats itself. Help please.
Howdy rcoo26,
It sounds like there’s an issue turning your MacBook Pro on when it isn’t connected to power, and the battery doesn’t seem to be holding a charge. The article below provides information that can help you troubleshoot the battery in your notebook.

Hey!
I have a really strange problem and need answers fast!
Im running the latest version of Premiere CC (2014) on the latest Macbook Pro retina 15 inch, fully upgraded.
When I export, very randomly I get failed video exports. Its in different spots in the export, but the "Glitch" is exactly the same wherever in the video it turns up.
The upper left corner of the video is unaffected, but the rest of the frame "flickers", it looks like every other frame is black.
This problem is not specific to any type of format, it will just happen randomly somewhere in my export.
This is a major problem, im currently having to do all my exports on my coworkers computers.
I would greatly appreciate your help!
Cheers,
SimonFirst off, please always report the exact version number as shown in the About box. We have way too many cases where people report "I'm on the latest" only to determine later that in fact they're not.
If you are indeed on the very latest version, CC2014.1, and if the problem section has Warp Stabilizer applied, then please check whether Renderer is set to use GPU acceleration and, if so, switch it to Software Only. We've had reports from a few customers of a similar problem in 2014.1 with warp stabilizer and GPU acceleration.
If this fixes your encodes, then please report back with your graphics card model and driver version. Also, let us know whether GPU acceleration was working correctly with warp stabilizer in the prior version. -

Help please, Any help to overcome this problem will be appreciated.Then do this:
If you have your original installer DVD boot from it. Do you still get a panic? If not, then backup the computer, erase the drive, and reinstall Lion:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
Note, that if you cannot start from the Recovery HD without experiencing a panic, then you have a hardware failure.
Be aware that the panic report you posted is usually always associated with GPU failure for your specific model. It does not have anything specific to do with upgrading Lion or to Lion. -

FaceTime Problem - MacBook Pro Retina
Hello everyone, as the title suggests, I have a problem with FaceTime.
During a video call (only a video call, during FaceTime Audio I don't have any problems) I hear and see the other person well, but the other person sees me and feels jerky, sometimes subtle, but sometimes that makes it impossible for the other person to understand me. Tried with three different people.
how to solve?
It is not a wifi problem because I've tried with the iPhone and it did not give these problems ...
Thank you!
MacBook pro Retina (13' late 2013) 512 GBHi there,
I have the same computer as you, and I've noticed the same thing. Both facetime and skype have similar audio issues. I can seem to hear the other side fine, but my audio particularly breaks up a lot.
The audio though my phone is perfectly fine when I facetime though the same network using my iphone. I previously had a 15" macbook pro late 2011 and the audio was fine. I realize the microphones are different in this new retina (late 2013) model - though the audio problems seem to occur even with an external microphone as well. -

also i download the app Chameleon SSD Optimiser and turn on everything
I really need help!!!
PLEASE HELP!!!
I USE MY MACBOOK PRO FOR PRESENTATIONS!!!I had never heard of "Chameleon SSD Optimiser" but I took a look at it after reading your message... I'm not sure that 'turning everything on' was a wise idea... enabling TRIM is fine, of course. I wouldn't think that 'Chameleon' options would have anything to do with your problem, however.
What sort of adapter are you using with your Samsung monitor? I would imagine that there is either a hardware fault with the adapter, or with either your Mac port or the port on the monitor.

Severe wireless problems; MacBook Pro 13inch Early 2011
I just installed updates on my MacBook Pro 13inch early 2011. I now have severe problems with my wireless. What can I do to undo the updates? One of them was a firmare update.
There is generally no need to undo the Updates, just Re-Do your wireless setup:
System Preferences > Netowrk > WiFi > ( Assist Me ) ...

FireWire Audio Heat Problem (Macbook Pro, Late 2008) VIDEO proof
http://www.youtube.com/watch?v=JYHnX3CGUoo
After a lot of hours of trying to figure out WHY my macbook pro heats up (a lot) when i connect my newly bought Apogee Duet firewire audio interface, i found out that actually what was happening is that there are CPU spikes of extremely short period (so short that Activity Monitor and iStat could not catch) constantly spiking the CPU frequency from 1596Mhz (Idle) to 2572Mhz (Maximum). Apart from the frequency spike there is also a VOLTAGE spike from 1.0v to 1.15.
I know that this is normal due to speedstep technologies and such BUT the rapid spiking and alterations of frequency and voltage ALWAYS happening when i have my Firewire audio plugged is not normal to me. There is nothing else running, everything's idle and i only plug the firewire interface.
Also this is not happening when i restrict OSX from loading AppleFWAudio.kext (either by deleting, moving, renaming it). I connect the firewire audio interface, the leds are illuminating but no heat problem (thats to show you that is not because the interface is self-powered)
Whats going on seems to be similar with the problems occurred after Mac Pro Audio Update to users that was using FW audio devices. They were hearing a sine noise coming from their macpro and propably that was because the same thing was happening. Constant spikes of voltage to the CPU. I dont have a macpro thought so i cant apply the update Apple released for that issue.
Also, my macbook is using Lucent / Agere (LSI) firewire chipset (the particular and known revision 6) but i dont think that this is the cause since Apogee didnt have any problems with the chipset
Info: The app im using to monitor the Frequency and Voltage is CoolBook, can be found here: http://www.coolbook.se/CoolBook.htmlFirewire Audio disconnected / or AppleFWAudio.kext unloaded = Idle temp arround 50 celcius (iStat)
Firewire Audio Connected with AppleFWAudio.kext loaded = Idle temp arround 60 celcius (iStat)
If theres a possibility that this is due to bus powered firewire device (cause i have an external FW hard drive that is self-powered and temps are not rising when i connect it) then AppleFWAudio.kext maybe manages something with bus powered firewire.
Maybe when i have the interface connected but the kext not loaded the mA sucked by the interface are too little for causing a temp rise but by the time the kext is loaded and the interface is converting audio the mA required tops up so the temp rise comes from the mA load on the firewire bus and not the cpu itself.
*Even if that's the case, the rapid spikes of throttling on the cpu by the time the Firewire Audio interface is connected bothers me. This isn't something that should normaly happen on an idling machine.*

Why can't widgets just stay on my desktop?
Having to click on the dashboard is not as convenient as if the widget just stayed on my desktop. Is there any way to overcome this limitation? Thanks.
