This article will show you a quick method for migrating your iTunes library, it may guide you to fix the problem of moving iTunes library from PC to Mac.
Step 1: Setting the stage
Make sure you're running the latest version of iTunes on both your Mac and your PC.
Step 2: If you have an iPod, make it cross-platform
This step will allow you to sync your iPod to both your Mac and your PC, without any hassles. To do this, connect your PC-formatted iPod to your Mac. iTunes will launch and present you with an error screen asking if you'd like to erase this iPod and sync it with the iTunes library. Don't panic and select "Cancel."
Your iPod's icon should appear in the left iTunes window pane. Select the iPod so that the Summary information for your iPod appears in the main window. Check off the box marked "Manually manage music and videos." By enabling this feature, your iPod can be seen by both Mac and Windows machines without prompting you to erase or overwrite your files.
Step 3: Transfer purchased music to iTunes
Go to the File menu in iTunes and select "Transfer purchases from iPod". iTunes may ask you to reenter the Apple ID (e-mail address) and password used for your iTunes store account, in order to verify that the purchased music belongs to you. You may also want to make sure your new computer is authorized to play your previously purchased music by going to the iTunes "Store" menu and selecting "Authorize computer." You'll be able to find your purchased music in your Mac iTunes music library now.
Step 4: Copying the rest of your music
Method 1: If you happen to have your entire digital music collection stored on your iPod, one quick way to transfer all your files from an iPod into a Mac version of iTunes is to download and use a Mac-only application called Senuti.
With your iPod connected to your Mac, and the Senuti application open, you should be able to see the contents of your iPod in Senuti's iTunes-like application window. All you need to do now is select all or part of the songs on your iPod, then hit the copy button in the upper-right corner of Senuti's application window. After a few minutes of copying, your iPod's files should now all appear in your Mac's iTunes music library.
Method 2: If your music collection is larger than what can reasonably fit on your iPod, then you'll need to copy your PC's iTunes library directly onto your new computer or onto an external hard drive. Copying your library onto an external hard drive is probably the best option, since it gives you an opportunity to create a backup archive of your music.
To get started, first you'll want to make sure your PC's iTunes library is ready to transport. To make sure all your files are accounted for, open up iTunes on your PC and under the "Advanced" menu select "Consolidate library." This will make sure that all of the music and video files you see in iTunes are collected into one main iTunes library folder on your computer. This step may take seconds or several minutes, depending on how your music and libraries are organized. You'll also want to go into the iTunes preferences (found in the edit menu) and make sure that both the Advanced tab's "Keep iTunes Music folder organized" and "Copy files to iTunes Music folder…" boxes are checked.
Next, you'll need to locate your PC's iTunes library folder. It should be located in the My Music folder, found in the My Documents folder on your PC's C:/ drive. Once you've found the folder named iTunes, open it up to find the folder called iTunes Music. The iTunes Music folder is the one you'll want to copy. It contains all your music organized neatly into folders.
Note: At this point, you can either drag the entire iTunes Music folder onto your external hard drive, or you can create a new folder on your external hard drive and selectively drag in just the artists, albums, and songs that you want transferred to your Mac. If you have lots of old podcasts clogging your iTunes library, you may want to delete them from your library before you begin copying.
Step 5: Importing your library onto your Mac
Disconnect your external hard drive from your PC and connect it to your new Mac. Now, launch iTunes on your Mac and under the File menu, select "Add to Library…". A window will pop up asking you to locate the files you want to add. Direct it to the iTunes library folder you copied onto the external hard drive and click the big blue "Choose" button.
After a few minutes, your PC's iTunes files should be available in your Mac's iTunes library. You may have to spend some time relocating album artwork for some of your old files, but it sure beats burning a spindle full of CDRs to copy your files between computers.
