El Capitan, the last edition known as Mac OS X 10.11.6, is an operating system between Yosemite and macOS Sierra, released on July 18, 2015. Here is a list of new features that Mac OS X 10.11.6 brings to most old Mac OS X users. The all new OS X 10.11.6 for Mac has been released by Apple as beta update for OS X developers and non-developers (public beta testers). Mac OS X El Capitan 10.11.6 Beta (Build: 15G26a) is now available for update / upgrade / installation on Mac devices running an old OS X versions. The Direct Download Links of OS X 10.11.6 Beta Delta / Combo.DMG Update Files are available.
If you have a mid 2009 MacBook Pro, you can't update the OS. To update, you need a MacBook Pro (Mid 2010 or later) Model 6.2 and higher.
If you are careful about what you download and where you search on the Internet, your computer is useable without the latest security updates. My last computer had a 10.6 partition which I used every night. That was after El Capitan was released, so the OS was 5 versions behind. By being careful, I never had any problems.
I would make sure that you had at least 2 separate backups on 2 separate drives in case you have problems. That will allow you to recover.

Check compatibility
The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.
If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it might say that it's not compatible with this device or is too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:
- macOS Catalina 10.15 hardware requirements
- macOS Mojave 10.14 hardware requirements
- macOS High Sierra 10.13 hardware requirements
- macOS Sierra 10.12 hardware requirements
- OS X El Capitan 10.11 hardware requirements
