macOS is polished out of the box, but customization can make it feel more personal. From wallpapers to menu bar tweaks, here are solid free options that don't require subscriptions or compromise your Mac's performance.
Live Wallpapers: Wallspace
Wallspace is the standout free option for live wallpapers. No account, no ads, no trial expiration. You get HD wallpapers, custom MP4 support, and multi-display — all free. The app stays under 2% CPU, so it won't drain your battery. Pro ($6.99 one-time) adds 4K and lock screen, but the free tier is fully usable. Download Wallspace.
Static Wallpapers
For static wallpapers, macOS built-in options work well. System Settings → Desktop & Screen Saver lets you pick from Apple's collection or your photos. Third-party apps like Unsplash (via their Mac app) offer free high-res images. No need for a paid wallpaper app if static is enough.
Menu Bar Customization
Several free apps let you reorganize or hide menu bar icons. Bartender (freemium) and Hidden Bar (free, open source) are popular. They clean up clutter without changing how macOS works.
Dock Tweaks
macOS doesn't offer much dock customization natively. Apps like cDock (donationware) or manual Terminal tweaks can change appearance. Use with caution — some tweaks can affect stability.
Theme and Color
macOS has limited theming. Accent color is in System Settings. For more control, apps like Wallpaper Engine alternatives or dynamic wallpaper switchers exist, but many are paid or heavy. Wallspace fills the live wallpaper niche without the bloat.
