Hello, I m experiencing several issues with my Macbook Pro and would like to know how to return it to factory settings. Like it was when I opened the box. It's the 2011 one. With Lion, so no discs.
Reboot and hold down CMD R from the startup tone to the logo.
Use disk utility to erase your MacIntosh HD and then use the restore Lion to download and install.
What All Partions and stuff will I need to choose?
Just your OSx boot partition.
will my datta stay in the computer after this process?
If you erase your HDD with Disk utility, all data will be erased. Backup your data before you begin the installation.
