This is how you sync your Impresssion with your Mac:
1. Activate Bluetooth on Mac (buy a Bluetooth adapter if you don't have built-in BT)
2. Activate BT on your phone.
3. Download Samsung iSync plugin below.
4. Install iSync plugin.
5. Go to Macintosh HD (your hard drive)>Library>PhonePlugins.
6. Double click on Samsung_Unified_iSync_Plugin.phoneplugin.
7. Go to Contents>Resources, then open up MetaClasses.plist with TextEdit.
8. Scroll to bottom, where you will see a bunch of names of phones. Add in this to the list: <string>SAMSUNG ELECTRONICS CORPORATION+SGH-A877</string>
9. Save the file, and close out of it.
10. Don't open iSync yet! Make sure your phone and computer are paired and that Bluetooth is on on phone and computer.
11. Now open iSync.
12. Hit Sync Devices, and it will prompt you to add a device (if you've never used iSync or you've never added any devices). Add one.
13. Your phone will show up in the menu that appears! Double-click it.
14. Hit Sync Devices.
15. It *should* work.
