Live Wallpapers Should Not Make a Mac Feel Slower

A live wallpaper has one job: make the desktop feel alive without making the computer feel busy.

That sounds obvious, but video on the desktop creates a different set of expectations from video inside a player. A wallpaper has no playback button, no visible timeline and no reason to demand attention. It can remain on screen for an entire workday, across multiple displays and through every change of window.

Backspace was built around that constraint. It brings more than 1,000 4K live wallpapers to the Mac desktop and Lock Screen, but the size of the collection is only useful if browsing, applying and running a wallpaper still feels like part of macOS.

The first challenge is choice. A large library can easily become a wall of thumbnails. Backspace organizes its collection into curated groups so that people can move by visual direction rather than search through filenames. The point is to find a wallpaper that fits the display and the room quickly, then return to whatever the Mac is actually being used for.

The next challenge is multiple displays. A MacBook on its own is a simple target. A MacBook connected to an ultrawide monitor, a vertical display or two screens with different resolutions is not. The wallpaper system needs to understand that each screen has a different role and that the same visual may not suit every aspect ratio.

Lock Screen support matters for the same reason. The Lock Screen is part of the visual identity of a Mac, but it is often treated separately from the desktop. Backspace carries motion across both surfaces so the experience does not end when the computer locks.

Performance is the part users should notice least. A wallpaper should not compete with a video editor, a game, a browser full of tabs or a battery that has to last through the day. Playback behavior therefore needs to react to how the computer is being used instead of acting like a normal video left running behind every window.

This is also why importing arbitrary videos is not the purpose of Backspace. The app is built around a prepared collection, consistent presentation and a direct way to move from browsing to a finished desktop. It is closer to choosing a system appearance than managing a folder of media files.

Backspace includes a 7-day free trial so the wallpapers can be tested on the actual Mac and display setup before purchase. After the trial, it costs $8.99 as a one-time purchase with no subscription.

The complete collection and trial are available at backspacemac.app.

Why the Mac Notch Should Do More Than Hide a Camera

The notch occupies one of the most visible areas of a MacBook screen, but macOS mostly treats it as empty space. It contains the camera, divides the menu bar and then disappears from the rest of the experience.

DynamicHorizon started with a simple question: what if that space could respond when something on the Mac changes?

The result is a native macOS app that turns the area around the camera into an interactive surface. It stays compact when nothing requires attention, then expands for music, downloads, timers, calendar events, notifications, battery changes and connected devices.

The goal was not to copy an iPhone interface and stretch it across a desktop. A Mac has a pointer, multiple displays, long-running tasks, external audio devices and windows that remain open for hours. The interface had to belong to that environment.

Music is one of the clearest examples. When playback begins, album artwork and track information appear beside the notch. Moving the pointer to the top reveals playback controls and more detail without opening the music app. The same surface can expose audio-device controls, which matters on a computer that may move between built-in speakers, headphones, monitors and desk setups during the day.

Downloads and timers required a different approach. Both are useful precisely when the user does not want to keep the originating window open. DynamicHorizon keeps their progress visible at the top of the display, then gets out of the way when the information is no longer relevant.

A physical notch cannot be assumed. Some Macs do not have one, and many MacBook users connect one or more external displays. DynamicHorizon therefore adapts its shape to the screen. On a display without a camera cutout, it becomes a floating island at the top rather than pretending that hardware exists where it does not.

The Lock Screen presented another opportunity. macOS already knows what is playing, but that information does not always remain useful once the computer is locked. DynamicHorizon adds album artwork, playback controls, synchronized lyrics and weather to the Lock Screen, allowing music to continue as part of the Mac rather than becoming invisible behind it.

Building this natively matters. DynamicHorizon has to follow display changes, playback state, timers, downloads and system events while remaining quiet in the background. Every animation and expansion competes with the work already happening on the screen, so restraint is as important as the number of features.

The app is also designed for direct ownership. DynamicHorizon costs $11.99 as a one-time purchase, with no subscription.
