Safety overview
Status: Safe
Homebrew is legitimate software widely used to manage developer tools and other packages on macOS. It can download, install, update, and remove software, so changes you make through it can affect development environments, shell configuration, and apps installed with Homebrew. That level of system access is normal for a package manager. Use trusted package sources, review commands before running them, and be careful with uninstall or cleanup actions if you rely on tools installed through Homebrew.
Recommendation: Keep Homebrew if you use Terminal-based tools, development software, or apps installed through brew. If you no longer use it, you can remove it, but expect any software managed by Homebrew to stop updating or stop working until it is reinstalled another way.
