MAC OS is not designed to be down-gradable which you cannot downgrade it through an installer.
You will need to create a bootable install disk (Apple support).
If you decide MAC OS Sierra is not working out for you, you can downgrade it back to OS X El Capitan using the following steps.
The steps are as follows and it like a full OS reinstall.
If you’ve decided you’d rather return to OS X El Capitan, you can downgrade with just a few steps. It is a bit of a complex process, but if you follow the steps you’ll be back to your old setup.
1: Back up your Mac
2: Create a bootable drive of OS X El Capitan
3: Erase macOS Sierra
4: Reinstall OS X El Capitan
5: Restore data from an earlier El Capitan Time machine backup
This process will erase macOS Sierra from your hard drive entirely. That means any files, programs, or documents you’ve been working on while using macOS Sierra will also be erased if you don’t back them up first. Use an external hard drive or a cloud-based program like DropBox, OneDrive, or iCloud. If you don’t save these important files somewhere off of your computer you will lose them.
Before you erase macOS Sierra from your computer, download OS X El Capitan from the Mac App Store. It should be in your purchase list, or you can simply search for it in the Mac App Store. You’ll need a copy of OS X El Capitan in order to downgrade from macOS Sierra.
After the process is complete, quit Disk Utility from the drop down menu in the upper left corner of the screen to go back to the OS X Utilities selector.
After you have erased MAC OS Sierra, you will want to reinstall an earlier operating system.
OS X El Capitan will install like a standard update. You will agree to the licensing terms before the software reboots on your Mac.
Note: Depending on how old your Mac is, you may download an older version of OS X, possibly the one that originally shipped with your computer (especially if you end up in Internet Recovery Mode). If that happens, complete the installation of the older operating system (IE. Mavericks or Yosemite). Once the installation is complete, open the Mac App Store and download OS X El Capitan from your Purchased list.
If you have a recent backup of your Mac saved via Time Machine (which you should), you can use it to reinstall OS X El Capitan.
Your Mac will begin restoring from the Time Machine backup and then reboot. This process can take a while.
