Cant Install El Capitan

/ Comments off

I have downloaded El Capitan both from the App Store and from Apple online, and I can download it. The problem is that I can't install it because my MacOS version is too old according to the installation program. But I will try to download Sierra now. I don't care which version I get as long as it ables me to update Chrome and other software. Can't Install El Capitan. Posted by 4 years ago. Can't Install El Capitan. Hello, I have an A1278 Macbook Core 2 Duo 13' from late 2008.

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

OS X could not be installed on your computer

Hackintosh can

Download El Capitan

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

Quit the installer to restart your computer and try again.

I checked Appleā€™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.
