MacTechTrainer :

Hello and thank you for asking your question, with JustAnswer.com/Mac. I am Sr. Mac Tech Support Specialist, Terry, glad to assist you.

MacTechTrainer :

Here are some steps you can try to resolve the issue:

MacTechTrainer :

• First, hold in your power button for approximately 10 seconds to do a hard shutdown.

MacTechTrainer :

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)

MacTechTrainer :

This should help with the freezing issue:

MacTechTrainer :

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

MacTechTrainer :

• Turn on the computer.

MacTechTrainer :

• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

MacTechTrainer :

• Now, hold the keys down until the computer restarts and you hear the startup sound for the third time.

MacTechTrainer :

• Release the keys and allow the Mac to start up.

MacTechTrainer :

• Please update me to let me know if this works.
