Install

Homebrew

One line, and the app opens on the first double-click. Here is what that line is doing.

It is a package manager
Software that installs other software, from the terminal.
Free, and not ours
An independent open-source project, used across macOS.
It skips the Gatekeeper dance
The cask clears the quarantine flag, so the app just opens.

brew install --cask yusufdiallo1/tap/cappture

What Homebrew actually is

Homebrew is a package manager for the Mac: a program whose job is installing other programs. You type one line into Terminal, it fetches the app, puts it where macOS expects it, and keeps track of what it installed so it can update or remove it later.

It is not ours, and it is not a store. It is an independent, open-source project that a great many Mac developers use, and it holds no account and takes no payment. If you have ever watched someone install something by typing brew install, this is that.

You do not need it to run Cappture. The disk image works identically. Homebrew is simply less work.

Why we recommend it

macOS marks anything downloaded from a browser with a quarantine flag. The first time you open such an app, Gatekeeper refuses, and you have to right-click, choose Open, and confirm — or go through Privacy & Security in System Settings to allow it.

Installing through Homebrew clears that flag as part of the install, so Cappture opens on the first double-click. Nothing is bypassed and no protection is weakened: the app is signed and notarised either way, and this only saves you the dance.

It also means updates are one line rather than a visit to a download page.

If you have never opened Terminal

Open Terminal. Press ⌘ Space, type “Terminal”, press Return. A window with a text prompt appears. Nothing is running yet.
Install Homebrew, if you do not have it. The command is on brew.sh, their own site. It asks for your password, because it is putting files in a shared location.
Run this line. It prints what it is doing as it goes. When the prompt returns, Cappture is in your Applications folder.
brew install --cask yusufdiallo1/tap/cappture

If any of that goes wrong, the help page covers what the errors mean.

Where the cask lives

The formula is in our own tap — a small public repository Homebrew reads to find the app: github.com/yusufdiallo1/homebrew-tap. You can read exactly what it installs before you run it, which is rather the point of it being public.

Homebrew picks up new releases from it on its own, so brew upgrade finds them without us telling you.

Removing it

brew uninstall --cask cappture takes the app off. Your captures are not touched — they live in your own folders, and nothing we install goes near them.
