By design, the iphone will sync itunes content with one computer at a time. Any attempt to sync such content with a second computer will result in ALL itunes content being first erased from your phone & then replaced with the content from the second computer. This is a design feature and cannot be overridden. Because you replaced your computer, your phone, sees your computer as a "new" computer. The itunes content sync is one way: computer to phone. If you have photos that were synced to your phone or music ripped on your own that were not backed up, you will first have to extract them from your phone using third party software, before you do anything else:
Once you've done that, do the following in the order specified:
1. Disable auto sync when an iPod/iPhone is connected under Preferences>Devices in itunes(under the edit menu if using Windows).
2. Make sure you have one contact & one event in the supported applications(Address Book & iCal) on your computer. These entries can be fake, doesn't matter, the important point is that these programs not be empty.
3. Connect your phone, iTunes running, do not sync at this point.
4. Store>Authorize this computer.
5. File>Transfer Purchases(To make sure all purchased content on your phone will be in your itunes library).
6. Right click in the device pane & select reset warnings.
7. Right click again and select backup.
8. Right click again & select restore from backup, select the backup you just made. When prompted to create another backup, decline.
9. This MUST be followed by a sync to restore your itunes content, which you select from the various tabs, You'll get a popup regarding your contacts & calendars asking to merge or replace, select merge.
You should be good to go.
Let's try the easy approach first. Connect the old and new computers to the same network, share the Documents folder on the Mac, and connect to it from the old computer (you will need to go to System Preferences on the Apple menu, Sharing preferences, Options and check the box for SMB sharing). Then copy the iTunes library and anything else you want on the Mac across the network. I just did this a couple of days ago, and it worked swimmingly.
An alternative is to buy a USB hard drive (1 terabyte drives are under $100 now), copy all of your Documents folder from the old computer onto it, then copy all of the content to Documents on the new computer. After everything is copied reformat the USB drive, connect it to your Macbook, and OS X will automatically use it as a Time Machine backup drive.
Before doing any copying be sure you exit iTunes. After copying launch iTunes, Authorize it 9if you haven't already) and make sure you can see your music in iTunes and make some random checks to make sure it plays, then sync your phone.
