How to Add Your Own Videos as a Screensaver on Mac
Mac screensavers have come a long way from floating clocks and flying toasters. If you'd rather watch your own travel footage, time-lapses, or family videos drift across the screen when your Mac goes idle, you can — but the path depends on which version of macOS you're running and how comfortable you are bending the system a little.
What Mac Screensavers Actually Support (and What They Don't)
Out of the box, macOS doesn't include a screensaver option that lets you simply point it at a folder of .mp4 files and hit play. The built-in screensaver engine is designed around photo slideshows and Apple's own aerial/landscape video loops — not arbitrary user video files.
That said, there are two main routes people take:
- Third-party screensaver apps that hook into macOS and play video files directly
- Converting videos into a format the system or an app can interpret as a screensaver source
Neither is complicated, but each comes with its own requirements.
macOS Version Matters More Than You'd Think
Before doing anything, it's worth knowing which macOS you're on. The screensaver system changed notably with macOS Ventura (13) and again with macOS Sonoma (14), when Apple shifted to a new screensaver architecture that introduced interactive widgets and updated how screen effects are managed.
- On macOS Monterey and earlier, third-party screensaver
.saverbundles were straightforward to install via System Preferences - On macOS Ventura and Sonoma, the path is System Settings → Screen Saver, and some older
.saverfiles may trigger Gatekeeper warnings or fail to load entirely due to stricter security policies
🔒 Gatekeeper (Apple's app security layer) will flag screensaver bundles that aren't notarized by Apple. You may need to manually allow them in System Settings → Privacy & Security after an initial block.
Using a Third-Party Video Screensaver App
The most practical approach for most users is a dedicated screensaver application. Several exist — some free, some paid — that register as screensavers in macOS and let you select a folder of video files to cycle through. When your Mac idles, they play your videos fullscreen.
What to look for in these apps:
| Feature | Why It Matters |
|---|---|
| macOS version compatibility | Must support your specific OS build |
| Video format support | H.264, HEVC (H.265), ProRes — match your files |
| Playback controls | Shuffle, loop, speed, volume muting |
| Multi-display support | Important if you use multiple monitors |
| Apple Silicon native | Avoids Rosetta overhead on M-series Macs |
After installing, you place the app's .saver file in ~/Library/Screen Savers/ (for your account only) or /Library/Screen Savers/ (system-wide). Then go to System Settings → Screen Saver, find it in the list, select it, and point it at your video folder.
The Manual Route: Using macOS's Built-In Photo Screensaver With Converted Clips
If you'd rather not install third-party software, there's a workaround — though it has limitations. macOS's Slideshow screensaver displays images from a folder. You can extract still frames from your videos (using tools like ffmpeg, iMovie exports, or QuickTime's trim-and-export feature) and save them as JPEG or HEIC images. The screensaver will cycle through them like a slow slideshow.
This doesn't play actual video, but it works natively and requires no additional software beyond what ships with macOS. For some use cases — like showing landscape photos pulled from a time-lapse — it's perfectly adequate.
What Affects How Well This Works 🎬
Several variables determine whether video screensavers feel seamless or clunky on your specific Mac:
Hardware performance plays a role. Decoding H.265 video in a loop at 4K while the system is otherwise idle is manageable on recent Apple Silicon Macs, but older Intel Macs with limited VRAM may show stuttering or cause the fans to spin up more than you'd expect from a "resting" machine.
Video file format and resolution matter too. Most screensaver apps handle H.264 and H.265 well. Less common codecs (like older .wmv, .avi, or heavily compressed web formats) may require transcoding first. A quick pass through HandBrake or Compressor to standardize your library to H.264 MP4 at 1080p or 4K often prevents playback issues before they start.
Your screensaver trigger settings affect battery life on MacBooks. Running GPU-intensive video playback every time the screen idles for 2 minutes will draw more power than a static screensaver. Many users set a longer idle delay specifically because of this.
Energy Saver / Battery settings on macOS can also override screensaver behavior — if your Mac is set to sleep the display quickly, the screensaver may only run briefly before the screen turns off entirely.
Video Format Quick Reference
| Format | Typical Compatibility | Notes |
|---|---|---|
| H.264 (.mp4) | Excellent | Widely supported across all apps |
| HEVC/H.265 (.mp4/.mov) | Good on modern Macs | Hardware decode on Apple Silicon and newer Intel |
| ProRes (.mov) | Good, large files | Best for edited/professional footage |
| VP9 / AV1 | Limited | May require transcoding |
| WMV / AVI | Poor | Transcode before using |
The Part Only You Can Answer
What makes this genuinely personal is the combination of factors that only you can see: whether you're on a MacBook that needs to watch battery draw, how large your video library is, what resolutions and codecs you're working with, and how much friction you're willing to accept from a third-party install. Someone with a plugged-in Mac Studio, a library of clean H.264 clips, and comfort installing .saver files has a completely different experience than someone on an older Intel MacBook Air running the latest macOS with mixed-format footage.
The mechanics are consistent — your variables are your own to weigh.
