Hello! My MacBook Pro 13 "(Mid 2010) strange behavior when connected to the charger. In particular, the program does not work properly Mainstage 3: hang MIDI-messages independently switch presets. If you disable MagSafe everything works well. Tell me what is the problem and how to solve it?

Did you try & see if this may help?


•Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support


•Apple Portables: Troubleshooting MagSafe adapters - Apple Support


That should. If not, a diagnostic test may be necessary to see what else may be involved.

An Apple Store with Genius or specialist on staff may be of help for testing, also. If not

see an Apple authorized service provider, an independent authorized/trained agent. These

would be able to perform several levels of testing, troubleshooting, and provide estimate.


Good luck & happy computing! 🙂
