Upgrade system frameworks without upgrading OS I am currently running macOS 10.10.2, but would like to be able to run the latest Ableton Live 10 which is built on macOS 10.11.  When I directly run the executable I get errors referencing symbols not found in:

/System/Library/Frameworks/AudioToolbox.framework/Versions/A/AudioToolbox.


Of course this issue would be resolved by upgrading to 10.11, but that is something that I really do not want to do for a number of reasons, so I am wondering if I can:


Extract the relevant Framework files from a El Capitan InstallESD.dmg, and 
Overwrite the existing framework files with the new ones.


How much am I missing, or would this work?

Thanks

Edit:  I want to know if this is possibile, not if it is a good idea.
Ableton Live 10 isn't even released yet.

You should also check the system requirements.

  OS X 10.11.6 or later


So I think the answer to your question is don't modify system frameworks (sounds like a recipe for dependency hell) and either upgrade to macOS 10.11 or stick to using Ableton Live 9.
