I am getting electric current type shocks whilst using my track pad on my macbook pro. This happens when it is both plugged in to charge and also unplugged. I am left with a constant type pain of prickly pins and needles even when I am not using it.
I have recently bought a Macbook pro and have noticed that I am getting an electric current running up my fingers when using the track pad. This happens when it is charging but most worryingly it happens when it is not plugged in. It leaves me with pins and needles type feeling in my hand and arm even when I am not using it. Also when I sit it on my lap I get the same electrical current in my legs and down to my feet.
Surely this cannot be what I should expect with an apple product?, has anyone else experienced this?.
Yesterday I couldn't bare to use it the current was so strong. I went out for the rest of the day and suffered with pins and prickly needles all day.
Two possible courses of action suggest themselves:
(1) Return your computer immediately to point of purchase and/or authorized service provider.
or
(2) Consult with your doctor about your neurological symptoms.

If your trackpad is unresponsive, a good troubleshooting step is to reset the PRAM and SMC on your system. The following articles will show you how to do that. Also see the final article in this post that addresses general issues with jumpy or erratic trackpads.

Bought 10 gb Uploaded Iphone and IPad2, left with 2gb space. How to view pictures and other info in ICloud? Can I upload documents from my desktop (Windows os)?
Thanks.If you backed up your iphone to icloud, then there's a chance that doing a restore might bring back your photos. I say "chance" because many users have tried that (assuming they had photos turned in for backups in settings), but ended up not getting back any photos. If that happens, then they are gone.
Remember, you should have been syncing photos all along to a computer for archiving. Don't trust the pictures to an icloud backup. -
I bought my macbook pro this morning. When I turned it on it led me through set up with voice over. I finally quit VO but my pointer is not working. It moves but does not open anything. Can anyone help?

Thank you Shootist007. I cannot do even Update now. I probably should have spent the same amount of money on a new IMac!
No not really. If this is a brand new Macbook Pro take it back for a refund. Apple has a 14 day No Questions Asked return policy for Full refund.
Take it back, get the Full Refund (DO NOT LET THEM TRY TO FIX IT. YOU BOUGHT A NEW COMPUTER NOT ONE THAT HAS BEEN WORKED ON OR NEEDS TO BE FIXED) and then decide whether to buy another Macbook Pro or the iMac. Or you could return it, get the Full refund and buy some other brand computer. -

Those look alot like file names and not infection names. I don't find any reference to anything like that on Norton or VirusTotal. Since you said these were Trojans, I would expect to see "Trojan" as part of the infection name.
".jar" files are executable Java applets. The random alpha-numerics would seem to indicate a cache file, likely from a browser with Java enabled. And we all know what ".zip" means.
Worst case is that you had Java enabled in a browser and were infected by one of the late variants of the Flashback Trojan over a year ago or one of a couple of other attacks using the same vulnerability but targetted against a small number of political sympathizers. Much more probable is that thes were Windows only Trojans. Hopefully you have a fully up-to-date OS X, including Java, and have disabled Java in all your browsers by now. -
When I connect my Macbook Pro to my Dell DLP projector, either via cable or wirelessly, I just see a dark screen with the mouse and mouse trails only, can any one help?
jpmarkques post is a good start point, after folling his directions, you can try detect displays. Also try different rsolution and refresh rates.
Most of the projectors I have used support a 1024X768 res.
Youcan also try a pram reset if it still does not detect.
Leave theproctor connected and powered up, power down the MBP.
Power back up the MBP and hold the following keys before you hear the start up chime:
Option, command, P,R (no commas) continue to hold these keys till you hear the start up chime 2 times. -

How do I get the Airplay Icon to show on the System Preferences of my MacBook Pro?
How do I get the Airplay Icon to show on the System Preferences of my MacBook Pro? I want to be able to connect to my AppleTV.
I looked at that already. I've done everything it says: check to make sure wireless is working, make sure airplay is enabled, make sure device and apple tv are on the same network blah blah. The icon just isn't there. Unless I skipped a step. AirPlay works when I use it in the music app and in the video app, I jus can't get mirroring to work. I was looking at some other threads and mirroring doesn't seem to be working for a lot of people. Maybe I jus have to wait for an update =\

How can i get iphoto on my IPAD if i already have it on my macbook pro
how can i get iphoto on my IPAD if i already have it on my macbook pro?
See this page, if your iPad qualifies for a free download: Free Apple apps for iOS 7 compatible devices
iPhoto on the iPad and iPhoto on the Mac are completely different programs. The Mac version cannot run on the iPad, because the operating systems and the processors are different. Don't expect, that iPhoto on the iPad will be able to do the same things as your iPhoto for Mac, pr that you can keep the two iPhoto libraries in sync.
Se this help page for a description, what iPhoto on the iPad can do: http://help.apple.com/iphoto/ipad/2.0/ -
I have a 13 inch Macbook Pro. I have bought it just 5 months back. All of a sudden, i am unable to turn the mac on. It doesn't even get Charged. What could be the issue ?
If you're unable to turn it on, let alone even charge it then it definitely sounds like a battery issue to me. I'd wait for someone else to reply just to be sure but I think somehow the battery by the sounds of it must have died. However, I could be very wrong.
If you're still under applecare which you should be then it should be an easy free fix. Hope this helps! -
i have macbook pro 13.3 inch. I am installing window 7 in boot camp manager after copying file of window upto 67% it doesn't response and i had forcely shotdown my macbook. Now my macbook doesn't open and stop in black screen with cursor blinking. Now how could i open my macbook pro.
At startup hold down the Option/Alt key and from the screen that comes up select your OS X partition to start the computer from. Then use the Boot Camp Assistant app to Remove Windows and the partition you reated for it and it will Automatically place the space you allocated for the Windows install back into the OS X partition.
NOTE:
Do NOT use Disk Utility to erase the partition that was created for the Windows install. Use the Boot Camp Assistant app again to do that. -
