No Packages Were Eligible For Install Mac

admin

Installing El Capiton on an old Mac Book Pro today, I received the error:

OS X could not be installed on your computer

Mac Pro Mods PowerMac G3 B&W PowerMac G4 PowerMac G4 Cube PowerMac G5 Others Retail Cases Modders Tools. 'No packages were eligible for install'. My problem is that my Mac starts up to the 'El Capitan' installer. After restarting several times, OS X is still on screen telling me that 'no packages were eligible for install'. Can someone help please, and can you bear in mind that I’m not technically minded so keep instruction in simple terms.

No packages were eligible for install. Contact the software manufacturer for assistance.

Quit the installer to restart your computer and try again.

I checked Apple’s support Matrix (it is a very old macbook pro) at https://support.apple.com/kb/SP728?locale=en_GB and it was listed as supported.

After lots of Googling and investigation, I discovered that the date and time were not set to current, the macbook thought it was year 2000.

You can easily reset the time and date by following the steps below:

  • Click Utilities on the menu bar
  • Select Terminal
  • Type date
  • Confirm the date is wrong
  • Type date 062112422016 (example: June 21st 12:42 2016)
  • Exit terminal
  • Click Restart

Once the Date and time are configured you will be able to install OS X.

Easy fix, for a ridiculous error!
