When trying to restore an iPod touch or iPhone, if you cannot get iTunes to recognize your device, you must restore manually.

To do this:

• plug it in to your computer
• hold the home button and power button until the apple logo appears. This will launch iTunes and put the device into restore mode.

Sometimes this will not work, especially if a password has been set on the device. In cases like this, while still keeping the device plugged into your computer:

• hold the home button and power button for 10 seconds
• then release the power button and continue holding the home button for an additional 10 seconds.

This should boot the device into DFU mode and allow you to restore your device.

Sometimes Bluetooth will suddenly stop working.  I have found that – true to what you’ll find on the forums – if you zap the PRAM and reset the SMC the problem is often resolved.

I have also seen flash drives or external hard drives stop working properly (not mounting or unable to read or write). Upon investigation these drives were not properly ejected before removal!  Disk Warrior often resolves this, but the knowledge of how to properly eject a drive can prevent this.

First, download Address Book Exporter.

When you open it, select the group you would like to export or select all.  In the configure settings, select the fields you would like to export and whether you would like the columns in the first line (typically this is how I export things).

Export your address book and open it with Numbers or Excel. It’s just that simple!
