Mac book pro trackpad and arrow keys behaving erratically
Hi,
Over the past few months I've noticed my track pad and arrow keys not working as they should and the problem has been getting worse until a few days ago the trackpad stopped working all together only for it to come back to life for a few hours then get worse again.
Symptoms:
The cursor keep sticking, you can't drag it smoothly across the screen.It'll suddenly jump to the top of the screen or you can only move it left and right not up and down.
The main click stops working, it'll turn into a right click button so everytime you click I get a sub menu pop up.
When I use the arrow keys to navigate a sub menu the highlight jumps around as if it's possesd.
Sometimes I'm not touching anything and the cursor will move on it's own!?!
I've tried resetting the PRAM but it doesn't work. Everytime I restart the mac book it works fine for a little while then gets worse again.
Does anyone have a suggestion as to what's wrong with it?
Thanks
Chris
The possible cause could be your List is too lengthy. What you can do is don't refresh the list when they press the key down but put a Button beside. Once they selected the value in the dropdown then hey click the Button to get whatever needed.

Thanks - how would I do that?
I am thinking that another possibility is the FirstOrDefault
command that runs in the FocusItem method. I think that it is causing any arrow key (up/down) interaction to behave erratically, but I don't know what to use in its place.

I own a mac book pro 13" and I use parallels for work and desperately need the "pause" key that used to be on my PC. It is the equivalent of the f15 key. My keyboard only goes up to f12 and I have looked in here and on google and can't figure it out. doesn't anyone have ideas?
Thanks!I have found the solution for myself for the above. I use a specific scripting program which is accessed by Control A. To pause it, you need to use Control B. not sure if this would work for any other application but it resolves my dilemma after hours of trying!

trackpad? Or is it a failing battery? Or Both?
It could be trackpad, battery or both.
You have to take the computer to the Apple store to have it checked out as soon as possible

Hello,
I am trying to connect my laptop to my TV. The computer flashes blue after I plug the cable in but the TV says there is no signal.
I have a Mac Book Pro 2009 and a Samsung 32" Class (31.5" Diag.) 450 Series 720p LCD HDTV (2010 model).
I am using a mini display port to VGA adapter. I have sucessfully hooked up boh devices but it stopped working after a handful of times. I was wondering if there is anything I can do to fix the problem or is my cable broken?Some things you can try.

When will Windows 8.1 be supported on Boot camp 5? I have a new Mac book Pro 2013 and cannot install. Do I return the Windows version and try to download 8.0, or wait it out until it is supported? New to Mac's.
Apple please advise.Apple does not respond in these forums except occasionally an Apple employee will stop by. If you want to contact Apple, use the contact us link at the bottom of this page.
With respect to your question "When will Windows 8.1 be supported on Boot camp 5?" you are asking us to speculate as to when Apple will release their drivers supporting Windows 8.1. We do not know, and we can not speculate as to when. From the terms of use of this forum:

My mac book pro crashed and the logic board died. They said that i could get the hard drive out and it should have all my files on it. How do i get them off and put them on my new computer?

Do you mean a case for the external hard drive? See here. Hope this may be helpful to you.

i just bought a new mac book pro 13'' and i bought a toshiba 1tb hard drive aswell, i formatted it to mac but it will not show up on my tv so i can watch movies? and solutions or reasons why?
TVs don't support "Mac OS Extended (Journaled)", so you will probably have to use FAT32. To format the external drive, follow the same steps as you did to format it with "Mac OS Extended (Journaled), but in the erasing screen, select "MS-DOS (FAT)" as "Format". Note that FAT32 isn't compatible with files bigger than 4 GB. Also, you may have to format the external drive in a PC

I've ordered a new mac book pro 15" and i need to clean hard drive off my old PC...not really to move them to the mac, but just to save in case needed; mostly pics and office docs....any suggestions?
Buy an external USB hard drive and copy your data to it. Either that or burn them all to single or double layer DVDs (depending on amount of data you have). Or if it's really a small amount, consider putting it all on a USB memory stick.

I have a Late 2011 Mac Book Pro 17" and I want to install a Samsung 840 EV 2.5 1TB. What accessories if any do I need? I want to place my order once with all that is needed to install this equipment.
No you don't. All currently available commercial hard drives and SSDs have the same SATA connectors in the exact same place.
As to being plug and play that is up to interpretation. The drive will plug into the cable but then you have to partition and format the drive for the Mac OS X operating system and then install OS X on it or restore from a Time Machine backup or Clone from your original drive to the SSD. Those things aren't necessarily Plug & Play. Not hard, just time consuming. Some more than the others. -

Color don't work well in Mac book pro 13" and monitor flash sometimes? Please help me!
Color don't work well in Mac book pro 13" and monitor flash sometimes? Please help me!
Please describe the problem in as much relevant detail as possible. The "etrecheck" fad hasn't made that step any less necessary. The usual results of posting etrecheck output on this site without a full description of the problem are very poor.
The many "failed" warnings that etrecheck sometimes spews mean nothing. Those warnings are not a reason to reinstall the OS, or to do anything else at all. They should be ignored.
The better your description of the problem, the better the chance of a solution.
For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? What changes did you make, if any, just before it became slow? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup. -
I just bought a 2013 late model Mac Book Pro Retina and am wondering if it is worth installing windows through boot camp.
If I install the windows component in order to run an exe file and its component "Declans Korean Flash Cards"... will it make my mac suseptible to viruses overall due to having a windows component? also will it make my mac slower as wellIf you are only going to use one or two window only programs then I wouldn't waste the space. Try WinonX it allows you to install exe. Files on Mac without installing windows.

We had our Mac Book Pro stolen and have not been able to recover the serial number from our Best Buy receipt. We did register it with Apple during the set-up and downloaded music on it thru ITunes. Any chance we can recover the serial number from somewhere? Any details would be helpful. Thank you!
You can try going here, using the same AppleID you used on the machine:

I have a new mac book pro/LION and can't access my back up data when I click on "enter time machine". I need the back up data that I could access on my old mac book pro (that is now broken). I can only access time machine back up data that I've obtained since starting the new mac book pro. Tnx so much
Try doing a click-and-hold on the Time Machine icon in the Dock, then select "Browse Other Time Machine Disks".

Where can I find one of those soft silicone body covers (not hardshell) for the Mac Book Pro? And is this a good idea since Apple no longer makes them? I-phones use them now.
Personally I use the Speck hard case on both of my MacBooks and they are the greates! Look around on Amazon and eBay and you can find them for $30-40. I wouldn't really recomend a silicon case for a macbook, but it's your preference.
