I bought a Macbook pro this July. Everything has been normal except about a week ago I started noticing I had to plug things in a few times in order for them to connect. Today I realized that one of my USB ports has been the problem, not my devices. THey connect right away when plugged into the right USB port next to the SD slot, but not at all when plugged into the left slot by the firewire hookup. Is this a problem that has a quick fix or am I going to have to go to the mac store?
Reset the SMC and PRAM
SMC Reset:
Shut down the MacBook Pro.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
PRAM:
Shut down the MacBook Pro.
Locate the following keys on the keyboard: Command, Option, P, and R.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys. -
USB Ports on my MacBook Pro are not working
My MacBook Pro (Original) USB ports recently stopped working. They come up in system profiler as being there, but when I connect a device, such as a flash drive, no leds turn on, and no power is given to it. I have tried resetting the SMC and PRAM, but all to no avail. Does anyone have any suggestions? Thank you in advance for your help
I had a nearly identical issue today with a new CTO MacBook Pro...specifically, the USB ports on this new unit were unresponsive to devices being plugged to their slots. We reset SMC to no avail, unplugged all other non-essential peripherals, and still no change.
We were specifically trying to boot a previously functioning Seagate hard drive with a fully intact install of Snow Leopard. Eventually the MBP detected the drive and read the contents. We selected the externally connected drive for startup (which S/L found without issue) in System Prefs. At boot, no progress further than Apple logo (without animated gears indicating some type of load process).
Moved to an identically equipped secondary Thunderbolt MBP which presented with exact same issue. To further verify this was an issue with the USB ports on a Thunderbolt model MBP, we attempted boot of the externally connected drive to an iMac and then a MacMini. Both of these units booted the drive without issue. The Thunderbolt MBPs can see the drive, read the contents, but can't boot them.
Disk Utility verified and ran repair on the external drive and reported zero problems.
Both MBPs are being returned to Apple. Too much to risk for only having two USB ports. -
My USB port on my Macbook Pro stopped working and i tried the SMC reset and the one closest to the SD port still continues to not work. Is there anything i can do besides bringing it in?
I would do another SMC reset. If nothing changes you should take the computer in to an Apple store for a free diagnostic. You should make an appointment.

Why can I no longer use my exterior speakers connected to the USB port on my MacBook pro
QuestionWhy can I no longer use my exterior speakers connected to the USB port on my MacBook pro ?
Have you checked the Sound Preferences under the System Preferences and set it to USB speaker for the sound output? Sometimes it can change on its own or after and update of an App or the OS?

USB ports in my macbook pro stop working
For a few months now the USB ports in my Macbook Pro stop working. The mouse is unable to move the pointer, therefore, I have to use the trackpad to select things. Then, when i try to shut it down it refuses to shut down, so I have to hold the on/off button to turn it off. When I turn on the laptop, the problem goes away. It's been happening more often for the last few weeks. Is there a problem with the software or is it the fact that I never used a base to raise the laptop, until recently, to let air in below so it doesnt heat up so much?
Any help is appreciated.Hi h,

My USB port (closest to the screen) is not working? And what is an IR Receiver in my USB port?
Hi everyone,
I recently found out that my USB port, closest to my screen, is not working. Before I called Apple Care for help, I performed a PRAM and a SMC RESET, which unfortunately did not work. I called Apple Care and they help me troubleshoot simple resets such as, shutdowns and restarts. The representative I spoke with conluded that the physical hardware has an issue and must be brought to the Apple Store for a diagnosis. I called the Apple Store to at least budget the fee for getting a USB port fixed and it's about $300.00. I never dropped my macbook or had any sort tactile encounterment with hard surfaces by dropping or hitting. I don't understand how my macbook pro would be physically damaged. I then thought maybe my software was out of date (right now I am running 10.9 Mavericks) or I forgot to do the minor software updates, but I was at a lost again because my macbook is up-to-date. I searched for further help and found a way to monitor what's plugged into my usb ports. (I read in the apple forums that a girl had nothing in her usb ports, but upon looking at the System Information> Hardware> USB, that the macbook recognizes that there are drives in the ports) I looked at my ports; one is being used by wirless mouse (the port that works) and the other (the port that doesnt work) is being used by an "IR RECEIVER". Now, is the IR Receiver actually using that port and that's why my macbook cannot recognize other devices inserted into that port? Or is the IR RECEIVER suppose to be in that port and that the hardware for that port is simply damaged (which would mean I need $300.00 to get that fixed)? I know this is a lot, but someone help me?

"IR" is the standard abbreviation for "infrared," the portion of the electromagnetic spectrum used by remotes for many common devices (stereos, cable boxes, Apple TVs, etc.). The remote sends a coded stream of IR pulses; a corresponding receiver in the target device "sees" the infrared light and decodes it. The MBP's internal IR Receiver sends the received signals to the processor via USB through an internal hub.
The most recent MacBook Pros have dropped the IR receiver and no longer work with the Apple Remote. -
one of the key on my macbook pro is not working properly, can it be fixed by a cleaning spray or something. there is lot of dust in where I live and thought that might be the culprit. thanks Jason
Don't use any cleaning spray. Wipe with a moist but not wet microfiber cloth.

The sound on my Macbook Pro does not work.
The sound on my Macbook Pro does not work. When we press the volume buttons, the sound icon pops up, but the bar is full with a small "Does not work" circle below it, and nothing happens when I hit volume up or done. I went into system preferences, but there aren't any options there that I can see to change it.
"Unfortunately, it doesn't provide any help for a MacBook Pro, other than indicating to call Apple Support" (sic).
Au contraire. TS1574's title and affected products are thusly:
"Troubleshooting issues with no audio from built-in speakers on Macs
Products Affected Mac mini, MacBook, MacBook Pro, iMac"
As a result, the instructions of the article are relevant. To be sure, follow those steps, the last of which is to contact Apple.
So, by way of reminder, here are the steps to troubleshoot the audio on your MacBook Pro. There is no red light, so the port is likely fine. Headphones work, so clearly your sound card is fine.
1. Ensure an incorrect version of OS X is not installed. If one is, then reinstall or erase/install after backing up your data.
2. Remove any external audio devices from USB, firewire, etc.
3. Open Sys Prefs > Sound > Output
If Internal Speakers is listed, select it and test again.
If Digital Out is listed, confirm again that all external audio devices and cables have been removed.
If mute is selected, unselect it.
If the volume slider is low, raise the volume.
If the above simply doesn't fix it, the issue may be a corrupted plist. Apple Support might be able to help troubleshoot the issue further, per the last step of TS1574.
I hope it gets resolved for you. Good luck. -
The sound on my macbook pro is not working
The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.
HELP!!Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
Highlight Internal Speakers / Headphones
Make sure Mute is not enabled.
2. Remove the headphone.
If you see red light in the headphone port, plug the headphone
in and out of the port 5 or 6 times to flip the microswitch inside.
Sound output may be stuck in the digital mode.
3. Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
4. Applications > Utilities > Audio MIDI Setup
Audio Devices window
Side Bar
Click the Built-in Output.
Under Mute any of the boxes checked? If so, uncheck it. -
Please can somone help my in built cameral on my MacBook Pro is not working, the green light does not show again and the camera is not working . what can i do to active it back.
SemakoYuu can try to reactivate your iSight camera by opening up iMessage.. navigate to Preferences/Audio Video,and then click on Camera. IT shoudl be grayed-out if you only have one camera hooked up to your machine. If you have an external camera, then disconnect it from your machine.

ICloud sync with MacBook Pro does not work
I've installed iOS 5, updated Lion to 10.7.2, marked Calendar and Contacts sync in System settings for iCloud on my Mac. However iCal and Address Book sync between iCloud and Mac (MacBook Pro) does not work though there is no problem in syncing between iCloud and iPhone. Whether I create new event or contact, change existing one or delete existing one in iCloud this change is not reflected on my Mac and vise versa. I could not find a solution in this site or in forums.
Yep, worked for me, too and now contacts and calendar seem to be syncing perfectly. We'll see if it lasts.
Thanks for your answer. -

Here is YouTube's help page if you have no sound on YouTube videos:
