I've been trying to put my USB into the macbook but I can't find it anywhere. How do I get it to be recognized into the system. Also, I don't get why my USB can't be recognized. Please answer this soon.

- Try restoring the iPod, first from backup and then try to factory settings/new iPod to rule out a software problem.
- Look at the dock connector on the iPod. Look for abnormalities like bent or corroded contacts, foreign material and broken or cracked plastic.
- Could you have damaged something when you took the iPod apart and replaced the Home button?

My macbook pro running OS X 10.8.3 freezes when I plug an adapter into the displayport, even when nothing is connected to the other (vga) end. Anyone know a solution?

My macbook pro running OS X 10.8.3 freezes when I plug an adapter into the displayport, even when nothing is connected to the other (vga) end. Anyone know a solution? I have used this adapter with a macbook air and it works flawlessly, but the moment I plug into the minidisplayport the macbook pro freezes with a little spinning color wheel that goes on and on. . .

Hello there, sarhang27753.
First thing that would come to mind to resolve the issue would be SMC and PRAM resets. I've linked Knowledge Base articles below:
SMC

Lost all contact info. All my Aps are there but all the data/progress is missing. When I plug my iphone into the usb fto synch up with my itunes on the computer a message comes up and says "enter the password to unlock your iphone backup file". This is very frustrating

I suggest trying the update again after an hour or two. Sometimes, the notice that an update is available comes an hour or two before the developers actually sends the revised app out to be downloaded.

It talks extensively about charging in the user guide, and how USB ports on PCs and older Macs may not provide sufficient power to charge the iPad. The user guide is available for free from the iBook store (accessed directly via the iPad iBooks app).
My iPad charges fine when plugged in to the back of my iMac, but I would always prefer to use the mains adaptor to save the strain on my USB circuits (which can wear out if used heavily to power external devices).

My ipod touch 4 won't sync or register on my computer. The cord works, the usb port works, and when I plug my ipod into the wall to charge it work, but when i plug it to the computer nothing, not even charging. P.S. worked before I updated it.

You do have iTunes 10.7 or later on the computer, right?

When I plug my phone in, it is on the home screen and unlocked so I don't understand what I am doing wrong. This has never occurred before. Please help.

Get a powered USB hub.

When I plug my iphone into the computer to restore it I receive a "network connection timed out" message. However, all of our other iphones and ipod touches will connect fine.

When I plug my iphone into the computer to restore it I receive a "network connection timed out" message. However, when I plug in other iphones or ipod touches I can connect fine. Any help would be appreciated.

Try a powered external USB hub. It uses a 120V AC wall jack to power USB devices, and the Mac only needs to provide *just enough* to comminucate. Best Buy, Target, Walmart, ... about $20.

It is safe to download if your phone is not jailbroken. Before you download it, however, take some precautions:
Reboot your computer
Disable your antivirus and firewall
Connect the phone cable to a USB port directly on the computer, not a hub
Before updating right click on the name of the phone in iTunes and choose "Backup"
When you are given the choice choose "Download only", not "Download and Update"
After the download completes successfully click the Update button to install it.
Most of these steps are just being overly cautious, as most people ignore them and have no problems. But occasionally the extra steps save grief.

When i plugged my ipod into the computer it started to make buzzing and screeching noises. It became hot so i removed it and then the screen froze while it continued to make these noises. I have never had anything like this happen.

When i plugged my ipod into the computer it started to make buzzing and screeching noises. It became hot so i removed it and then the screen froze while it continued to make these noises. I have never had anything like this happen. (never gotten it wet or had it exposed to extreme temperatures) It is also unresponsive to any buttons on the ipod and it didn't show up when i plugged it into my computer. What do I do? Also if it is unfixable could i get a free one from apple?
