Why tensorflow library too large on macOS

Hi,all:

I tried download the macOS library from https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-darwin-x86_64-2.7.0.tar.gz

can not quickly understand why the library is too large, over 400MB, I think it’s hard integrate to client application, how can we get a small version library(on windows platform, just 20M).
