Installing El Capiton on an old Mac Book Pro today, I received the error:
- The exact message is one of those that appears in the link I posted: “This copy of the Install OS X El Capitan application can’t be verified. It may have been corrupted or tampered with during downloading”. And given that in this page (and in several others), people who had the same issue solved it by correcting the date, I strongly.

OS X could not be installed on your computer
I wanted to clear room on my computer, so I restarted the computer with cmd+r keys and opened OS X Utilities. I erased my drive and wanted to reinstall OS X El Capitan. After I agreed to the terms then selected my drive I signed into the Apple store.
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.
