Mac OS El Capitan is the twelfth major release of Mac OS X, that now named as Mac OS X, the latest version is 10.11 for Apple Inc, desktop. Mac OS X El Capitan is one of the most famous operating systems for Macintosh computers. I am having almost this exact same issue, I have an old MacBook Pro that I have previously had El Capitan installed on. The hard drive has gone funny and now I need to re-install El Capitan. But the only other Mac I have is an iMac, and I cannot seem to legitimately find a way to download El Capitan.
Hi,
No reason I can think of, except the possibility that you may have to upgrade some apps or replace them with something else. See http://roaringapps.com/apps to check compatibility.
El Capitan is the highest OS you can upgrade to: https://support.apple.com/en-us/HT206886

You should not notice a performance difference between Yosemite and El Capitan. El Capitan is basically a 'refinement' of Yosemite, not a major overhaul with additional features like Sierra is. As with (almost?) any Apple OS upgrade, security is improved. As you know, you may have to purchase newer apps for El Capitan. Some apps which come with the OS will offer updates once you upgrade to El Capitan.

Whether you stay with Yosemite or upgrade to El Capitan, you should upgrade your RAM to 8GBs, the maximum it will allow.
If you decide to replace your aging HD, consider a SSD for much improved read/write performance.
