I have a MacBook Pro. When I go to system preferences, the external speakers option does not appear on the input tab and, of course, the external speakers do not work. Help?

When you plug headphones in, or external speakers, where it states "internal speakers", it will rename that "headphones", say. Unless you are running an external sound card.

Hi,
I purchased Huawei Dongle and trying to connect with my new MacBook Pro (OS- Mountain Lion) USB port 3.0 but unfortunately it does not support.
When I plugged in my macbook the power is flowing in dongle due green light blinking twice in every 3 sec but no connection found or diver shown.
Please let me know how I have to use it. I got some suggestion for USB hub 2.0 but It does not make any sense and driver installation.
So please suggest proper direction to use it and provide link to install any driver.
Thanks
Tauheed Ahmad

Yes Clinton I did same, but they were (Huawei customer support) surprised about this problem, They behave like they have no idea about USB 2.0 and 3.0 knowledge. They handsUp that reason I posted my problem in this forum.
So is there any better solution to use any mediator between these USB version handling, Please let me know.
Thanks
Tauheed

I have a macbook pro with OSX Mavericks 10.9.5 and some keys that are not working. Specifically, the enter/return button, the "p", "0", ";", and all the function keys. What's really weird is that happens randomly. I've never spilled anything on it

I have a macbook pro with OSX Mavericks 10.9.5 and some keys randomly are not working. Specifically, the enter/return button, the "p", "0", ";", and all the function keys. What's really weird is that happens randomly. I've never spilled anything on it, and I can't for the life of me figure out how to fix this. Can anyone help? of course this happened after my warranty expired.

**update**
I don't know if this will help someone but I am posting this for that purpose. In the past when I first had this problem, I'd read a post somewhere (sorry, long ago, don't have the link) where an individual was having the same problem and they stated that when the MBP got heated, that's when the keys would stop working, and they went into the MBP and jiggle some stuff around (a specific wire, I'm not electronically inclined so I know NOT of what they spake!). Well I didn't want to do that but it always stuck in the back of my mind. I had given up, really, and was planning to take my MBP to the apple store. But by chance one night I left my MBP on the floor where it's cool, and when I turned it on, the problem went - poof! It seems there was some validity to the post that spoke about heat, because my problems started when I would stream foreign dramas on my MBP for hours at night, and I would hear the fan going off all the time, and in the mornings, my "p", "enter", "0", ";", and all the function keys would stop working.
So, maybe try keeping the MBP in a cool place when it's off. Since I've started doing this overnight every night (keeping it on the cool floor, out of reach of any big feet), I have not had a single problem with my keyboard.
Hopefully this might help someone.

I have a MacBook Pro and tried to download and open the torbundle package.

I have a MacBook Pro and tried to download and open the torbundle package. I get a message that reads "A copy of firefox is already running. Only one copy of firefox can be open at a time."
1. I do not seem to have firefox anywhere of my computer. Ive been using safari and as far as my computers library is concerned there is no firefox.
2. I have tried shutting down and restarting.
3. I tried making a new user account.
I believe the torbundle package is trying to open itself twice. Has anyone had this problem when trying to use tor on OS X?
This is getting very frustrating! Help please!

If you open Activity Monitor do you see a FireFox running? If so delete it.
Have you tried deleting and redownloading/installing?

I have a MacBook Pro and it cannot locate my Western Digital External Backup Drive.

I have a MacBook Pro and it cannot locate my Western Digital External Backup Drive. It used to work prior to Maverick but now it doesnt. Do I need a different cord or what can I do so I can use Time Machine with this drive?

Your problem is really with "Time Machine", backup software included with OS X since version 10.5, not with your Time Capsule router. For more information on Time Machine, check these Web pages:

I have a MacBook Pro laptop purchased in June 2011, and the superdrive no longer works. Rather than have it replaced, I'll buy a 3rd party superdrive that plugs into the USB port. Does it need it's own power source, or will the USB port suffice?

I have a MacBook Pro laptop purchased in June 2011, and the superdrive no longer works. Rather than have it replaced, I'll buy a 3rd party superdrive that plugs into the USB port. Does the external superdrive need it's own power source, or will the USB port provide enough power?

The Apple external SuperDrive actually exceeds the allowed power draw. Because of this, it is only trouble-free on certain models that accommodate this excess.
All others require an external Power source.

iCloud has nothing to do with your iTunes library sync. iTunes handles that.

Folders that I copy from my Macbook to my External Hard Disk does NOT appear on any other drive that I connect the Hard disk to (TV, PC, ... etc.)

I'm facing a bit of a problem.
Any folder I copy from my Macbook Pro to my External Hard Disk does NOT appear on any other device that I connect the Hard Disk to (TV, PC, etc).
The Hard disk format is "MS-DOS (FAT)".
The folders that are copied from Macbook appear when I connect the Hard Disk to my Macbook only, yet, the folders that I copy from a PC to the Hard Disk appear on Macbook, PC, and TV and are also available from editing from both Mac and PC.
I was advised to install "Paragon" software and I did but I'm not sure how to use it to convert the folders on the hard drive to any format that can be read on other drives or devices (NTFS or otherwise).
I'd appreciate some help. Thank you.

Hi Simon. How is it formatted, FAT or NTFS?
I only ask as OSX will only read NTFS partitions unless you install an App such as Paragon NTFS or Tuxera NTFS.

You have to have 10.7.2 to have the iCloud icon appear.
You need to upgrade to Lion, via download from the app store, $29 (US).

TS1702 the delete option does not appear when I try to edit pictures

When I try to edit photos on my I pad [elete} the delete option does not appear only the share or copy option are there Why?

If the photos were synced to the iPad you have to unsync them. You can't delete those form the iPod itself.

"photos" option does not appear in my interface. Do have Music, Movies, TV Shows, Apps and Radio. Photo doesn't appear on iPhone or iPod Nano

Are you looking at the tabs on the right-hand side of iTunes when you've connected and selected your device on the left-hand side of iTunes ? i.e. it should be one of the tabs that you use to chose what content to sync to the device : syncing photos
