Mac vs Windows output different binaries/file size (Mac outputs larger file size)

[keisto]

I saw imagemin had a closed issue around this, but hopefully I have provided some more info. (I'll be continuing working on this myself)

I am sharing a Laravel product between Mac and Windows. When windows users run npm run production images have no change. When Mac run that same command image binary changes and image becomes a larger size (binary changes) and all image need to be commited.

We use the same node and npm versions along with git config for line endings differences between Mac and Windows.

I believe the problem is within this plugin because changing the quality has no effect on the output image size on Mac (using latest beta version) but changing quality works on windows.
