AnimatedGif

AnimatedGif is an screensaver for Mac OSX / macOS that plays animated GIFs.

It also has a background mode to let you run the gif as a desktop background (or wallpaper). The background mode can be enabled under "Screen Saver Options" in macOS.

You can either open only one single GIF file or you can choose a directory that contains more than one GIF file. In case of a selected directory the option panel of screensaver will let you choose a time between 1 and 30 minutes after which the GIF file is randomly changed.

Since 1.5.1 also animated PNG (Animated Portable Network Graphics (APNG)) are supported (starting with OSX 10.10).

Compatibility

Note: AnimatedGif is not working with Catalina(10.15-10.15.7) and early versions of Big Sur(before 11.5.2) since screensavers are to strong sandboxed in this versions of macOS(this means no GIF files can be selected or read from local disk and also background mode is broken), see issue #57 and #63. Later OS versions of Big Sur starting with 10.5.2 make the Sandbox a bit more open and at least allow selection of local user files.

Since release 1.5.0 AnimatedGif supports Metal(API) for rendering.

When started AnimatedGif tries to initialise Metal as first choice for rendering. Only if this initialisation fails (on MacOSX versions older than El Capitan (10.11) or not supported Macs(usually Macs older as Mid 2012; except Mac Pro models from Mid 2010 with supported graphics card)) it tries to initialise OpenGL for rendering(as it was default between release 1.0 till 1.4.0).

Unfortunately the screensaver clock is not working together with background mode and will be disabled if background mode is enabled. But the clock works fine in normal screensaver mode.

Because Big Sur(11.5.2) still sandboxes screensaver the background mode is still not working and so this button will be automaticly disabled since release 1.5.4 when Big Sur(and Catalina) is detected. But background mode is still available on Mojave or earlier versions of OSX.
