# MacWall questions, answered

Short, direct answers about MacWall: the free trial and price, battery and CPU use, the Lock Screen, macOS 27, Intel Macs, multiple displays and refunds.

Each page answers one question about MacWall in a few sentences, then links to the documentation for the steps. For how-to guides see [the docs](https://macwall.app/docs); for how live wallpapers work on a Mac see [Learn](https://macwall.app/learn).

## Price and licenses

- [Is MacWall free?](https://macwall.app/faq/is-macwall-free): No. MacWall has a free 24-hour trial on every Mac, then Pro is a one-time payment for up to 3 Macs. There is no subscription.
- [How many Macs can I use MacWall on?](https://macwall.app/faq/how-many-macs-per-license): One MacWall Pro license activates on up to 3 of your Macs. Pro+ covers 5 or 10 Macs with the same features, and every license is paid once.
- [Can I get a refund for MacWall?](https://macwall.app/faq/macwall-refund-policy): Yes. Every MacWall license has a 7-day money-back guarantee, no reason needed: email support within 7 days. EU and UK buyers get 14 days.

## Battery and performance

- [Does MacWall drain your MacBook battery?](https://macwall.app/faq/does-macwall-drain-battery): A playing wallpaper uses some power. MacWall pauses behind full-screen apps and while displays sleep, and Pause on battery holds it whenever you unplug.
- [How much CPU does MacWall use?](https://macwall.app/faq/macwall-cpu-use): MacWall decodes video in hardware. With System Wallpaper playback on macOS 26+, the MacWall process uses 0% CPU after you quit; macOS still decodes the video.

## Lock Screen and your own videos

- [Can you put a live wallpaper on the Mac Lock Screen?](https://macwall.app/faq/live-wallpaper-on-mac-lock-screen): Yes, on macOS 26 Tahoe and macOS 27. MacWall plays your wallpaper on the Lock Screen and as the screen saver, with Pro or during the free trial.
- [Can I use my own video as a wallpaper on Mac?](https://macwall.app/faq/use-your-own-video-as-mac-wallpaper): Not with macOS alone, which takes only images. MacWall Pro adds your own MP4, MOV and M4V videos as private live wallpapers on your Mac.
- [Does MacWall work with multiple monitors?](https://macwall.app/faq/live-wallpaper-on-multiple-monitors): Yes. MacWall plays on every connected display, one wallpaper in sync everywhere or a different one per display, and remembers each monitor setup.

## Compatibility

- [Does MacWall work on macOS 27?](https://macwall.app/faq/does-macwall-work-on-macos-27): Yes. MacWall runs on macOS 27 Golden Gate with live desktop, Lock Screen and screen saver wallpapers. macOS 27 itself needs an Apple silicon Mac.
- [Does MacWall work on Intel Macs?](https://macwall.app/faq/does-macwall-work-on-intel-macs): Yes. MacWall is a universal app for Apple silicon and Intel Macs on macOS 15 or later. macOS 27 needs Apple silicon, so Intel Macs use 15 or 26.
- [Does MacWall work offline?](https://macwall.app/faq/does-macwall-work-offline): Yes, for wallpapers you've downloaded. New downloads and activating a key need internet, and Pro pauses after 7 days without a license check.
