WebViewScreenSaver

A macOS screen saver that displays a web page or a series of web pages.

Installation

• Using brew.*

brew install --cask webviewscreensaver

• Directly from the releases page. Unpack and double click to install.*

• From source (requires Xcode):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/janemiceli/web-page-screensaver-macos/master/install-from-source.sh)"

*Note: The package is adhoc signed (since v2.2.1, previously unsigned).

When opening it the first time you will get a security prompt about Apple not being able to verify the software.
Hit ok (cancel in older macOS) and go to Security and Privacy.
In the section explaining that "WebViewScreenSaver.saver" was blocked click Open Anyway.
Upon returning to screensaver options you'll get a second prompt that can be confirmed by clicking Open.

Alternatively:

• if you are using brew pass in --no-quarantine option to install or reinstall command:

brew install --cask webviewscreensaver --no-quarantine

• or if you installed it via direct download run the folllowing command to remove the file from quarantine:

xattr -d com.apple.quarantine WebViewScreenSaver.saver

Configuration

Open up System Preferences > Desktop and Screen Saver > Screen Saver and WebViewScreenSaver should be at the end of the list.

In the addresses section fill in as many websites as you want the screensaver to cycle through and the amount of time to pause on each.

Tip: To edit a selected row, click once or tap Enter or Tab.

Passing in a negative time value e.g. -1 will notify the screensaver to remain on that website indefinitely.

Need some website ideas? Check out suggestions in the examples section.

Local absolute paths can also be used as an address with or without the file:// schema.

E.g. file:///Users/myUser/mySreensaver/index.html

Note: If you are running Catalina or newer the provided path cannot reside in your personal folders which require extra permissions (this includes things like Downloads, Documents or Desktop) but can be anywhere else in your user's folder.

Configuration for IT

If you are interested in scripting configuration changes, WebViewScreenSaver, like most other screensavers, makes use of the macOS defaults system.

This can be queried and updated via:

defaults -currentHost read WebViewScreensaver

or directly (if installed for current user or should find it in /Library otherwise)

/usr/libexec/PlistBuddy -c 'Print' ~/Library/Preferences/ByHost/WebViewScreenSaver.*
