macOS may block the .saver file from an unidentified developer, a Security and Privacy setting or a terminal quarantine-removal command is needed on newer macOS versions.

Free to use for any purpose, including commercially, as long as you keep the copyright notice. The original Apple animations remain Apple's property.

In plain English

Brooklyn is a macOS screensaver that recreates the animated visuals Apple used during its special event on October 30, 2018, held at the Brooklyn Academy of Music. The screensaver was built by an independent developer, Pedro Carrasco, as a way to bring those animations to the Mac desktop. The project is open source under the MIT license, though the original animations remain Apple property. The screensaver works without an internet connection and offers a few customization options. Users can choose which of the animations appear, set how many times each one repeats before moving to the next, and toggle between light and dark color themes. The order of animations can also be set to random. Installing Brooklyn is straightforward. The easiest method is through Homebrew, a popular package manager for macOS, using a single terminal command. Alternatively, the screensaver file can be downloaded manually and double-clicked to install through System Preferences. On newer versions of macOS, the system may flag it as coming from an unidentified developer, which requires a brief step in Security and Privacy settings to allow it. If macOS still blocks it, a terminal command can remove the quarantine flag. Uninstalling follows the same two paths: a Homebrew command or deleting the .saver file directly. The project requires macOS El Capitan (10.11) or later and is written in Swift. It is no longer actively maintained, as noted at the top of the README, and the author states that bug fixes would require a fee arrangement. Contributions through GitHub issues and pull requests are still welcome.

Copy-paste prompts

Prompt 1

I installed the Brooklyn screensaver on macOS but Gatekeeper is blocking it. Give me the exact steps to allow it in System Settings and the terminal command to remove the quarantine flag.

Prompt 2

Show me how to modify Brooklyn's Swift source to add a new animation sequence that cycles between two custom colors.

Prompt 3

I want to build my own macOS screensaver in Swift similar to Brooklyn. What is the minimal ScreenSaverView subclass I need and how do I animate between multiple views?
