Installing El Capiton on an old Mac Book Pro today, I received the error: OS X could not be installed on your computer. No packages were eligible for install. Contact the software manufacturer for assistance. Quit the installer to restart your computer and try again. Once this is done, you have successfully installed OS X El Capitan. Method 3: Upgrade through Safe Mode. Finally, if the above solutions do not work out for you, what you can do is download and install the operating system in macOS Safe Mode. This is only for the users that are trying to upgrade from their current version to El Capitan. Aug 21, 2016 Sometimes I installed a new El Capitan on a new hard drive and needed to reinstall software like MS Office and I got problem of installing “The installer could not install the software because there was no software found to install.” It doesn’t matter what I did, I couldn’t install the software.
I have a few MacPro3,1's at my school I'd like to update to El Capitan 10.11.6. Currently they're running 10.5.8. I've got really slow WiFi-internet access, but the MacPro's do not have Airport. How do I attack this?
I want to make an up-to-date USB-install stick. I know I need to get hold of El Capitan, but my personal MacBook Pro is still running Mavericks. I can only update to Sierra. So I have to find an El Capitan-running Mac, but if I manage to get hold of the El Capitan-installer, it will be tied to their Apple-ID, right? Will El Capitan install without internet access?

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.
