MacOS – Clean install of Yosemite problem

hard drivemacbook promacos

Hopefully someone can help me. I've tried so many options. I purchased a used MacBook Pro, late 2011 model. The person I purchased it from said he wiped the hard drive, but when I got home, it seems he did that, however his login was still there.

So I did a disk utility, wiped the hard drive which checked out fine, got to the reinstall Yosemite page, but there is no hard drive icon, only the install Yosemite page. When I click continue I get this error, "An error occurred while preparing the installation. Try running this application again."

Just in case anybody else comes across this question, the steps to solve the system time/date issue mentioned above are as follows.

  1. Click on Utilities –> Terminal
  2. When the terminal window opens, type date and hit enter. What you will notice is that the date listed will be wrong. That wrong date is what is causing the reinstall error.
  3. To correct the wrong date –> type date followed by MMDDHHMMYYYY (Month – Date – Hour – Minute – Year)
  4. Exit and begin a new install, the problem should now be solved.
