Updating MacBook Pro

"Updating MacBook Pro: I am unable to use the software update, I even downloaded it from apple.com to try to update MacBook Pro but unfortunately it says it's damaged. Since I can't update my MacBook I can not download any apps until I have the newest software."

What to Try:

• Try in Safe Mode [Hold Down: command + r upon boot]
• Create a new user, and see if it installs in that user. Then, delete that user, once installed.
• Connect Ethernet

If you get a corrupted message...

Naw, it's not damaged, it's just that you have an old copy already in Applications, there are 2 cures...

Disconnect from the Internet & set the Date back to 2014, then you can run the Install MacsOS ******* App in Applications, so expired Certificates are not expired.

Trash the Install MacsOS *******.app in Applications then a new copy more recent version can be downloaded.
