Failed to install MacOS on MacBook Pro.
My MacBook Pro used by my son. I used this MacBook Pro as 2nd system administrator.
But I want to use this MacBook Pro as 1st system administrator, So I tried to install OS X on my MacBook Pro by "Erase and install OS X" but I failed to install OS X with the following.
"No packages were eligible for install, Contact the software manufacturer for assistance. Quit the installer to restart your computer and try again."
I tried FirstAd by Disk Utility, Nothing problem on disk (INTEL SSD**** Media) and disk images (OS X base system, OS X Install ESD) but when I tried FirstAid on my disk volume name (169.18 SATA Internal Physical Volume OS X Extened), displayed "FirstAid process has failed. If possible back up the data on this volume, Click Done to continue." When I clicked Show Details, displayed "Updating boot support partitions for the volume as required. Unable to unmount volume for repair. Operation failed..."
System Version is OS X 10.11.6(15G31).
I tried to press the power button and hold after restart or shutdown.But the system displayed the upper message again after the system automatically tried to install again. After restart or pressed the power button, the system automatically tried to install again, the I could not use this MacBook Pro again.
After exit OS X installer, the system displayed Startup Disk window but not listed the startup disk. But when I checked the disk utility, displayed the disk volume name.
Please let me know how to figure out this problem as soon as possible.
Thanks
