- Xcode, for iOS/Mac Development, is usually around 5GB (and
no, even if you remove every single simulator, it's still over 100-200MB).
- Android Studio is roughly the same deal as Xcode.
- I've not used Windows so I can't say for sure, but I'd be surprised if the various tech there doesn't follow this pattern.
77MB is nothing, and if you care about this, you're caring about the wrong things.
