Hi again, Juan.
OK this is just a guess but I believe that when you set up your rMBP from your old MBP you used TM restore not Migration Assistant. What happened is that you installed your old system OS10.7.4 and all files.
Using Migration Assistant (MA) would not have overwritten your OS.
See this taken from Finder Help....
Recover your entire system
If you use Time Machine to back up your computer, you can recover your system’s contents if your system or startup disk is damaged.
Important: Only use your Time Machine backup to restore your system to the computer that is the source of the backup. If you want to use your backup to transfer your information to a new computer, use Migration Assistant. 
Transfer your info from a computer or disk
If you’re restoring your system because of a problem with your startup disk, repair or replace the disk before following these instructions.
Make sure your Time Machine backup disk is connected and turned on. If your backup disk is on a network, make sure your computer is on the same network.
Choose Apple menu > Restart. Once your Mac restarts (and the gray screen appears), hold down the Command (⌘) and R keys.
Select “Restore from a Time Machine Backup,” and then click Continue.
Depending on your type of backup disk, do one of the following:
If you use an external disk, select it and click Continue.
If you use a Time Capsule, choose your AirPort network from the AirPort menu on the right side of the menu bar, and then select your Time Capsule and click “Connect to Remote Disk.”
If you use a network disk, select it and click “Connect to Remote Disk.”
If necessary, enter the name and password you use to connect to your backup disk, and then click Connect.
Select the date and time of the backup you want to restore, and then follow the onscreen instructions.
After you restore your system from a Time Machine backup, Time Machine may perform a full backup at the next scheduled backup time. This is normal. Time Machine resumes incremental backups after the full backup is completed.
I suggest you make an appoint at the Genius Bar at a local Apple Store and they will help you restore your computer. Make sure you take in your old MBP and your Time Machine back up disk as well.
Do not use instructions above for a TM restore now, because it will only reinstall Lion 10.7.4 not ML 10.8.X.
You need to reinstall ML first and then I think all of your problems will go away.
So did I guess right? Did you launch TM and restore or did you launch Migration Assistant to move files?
Hope this helps, if you cannot get to the Apple Store, I can try to walk you through reinstalling ML, but first we need to download a copy of ML.
