This copy of the install OS X application cannot be verified (corruped)

Few days ago I decided to install OS X Mavericks…

I created USB-installer and started the process…

But when I started, I’ve got the problem…

This copy of the Install OS X application can’t be verified. It may have been corrupted or tampered with during downloading.

Now I’ll show you how to fix this problem!

If you are making clean installation your MAC OS X and got those problem don’t be panic. Run Terminal from the Utilities and change the date.

Command looks like: 

date {month}{day}{hour}{minute}{year}

For example you need October 30th 2018 22:30.

So text in Terminal:

date 1030223018
