Pixelmator Pro Not Working? Common Errors & Fixes

Crashes usually come from an outdated app or macOS, corrupted settings or cache, or a damaged file. Updating, then resetting the app by deleting its Containers folder, fixes most cases.

Slowdowns and spinning beach balls mostly come from huge canvases, hundreds of layers, or stacked blur and adjustment layers that use a lot of memory and GPU. Merging layers and working at a smaller size help most.

After macOS 14.4, several users found that the HEIC Quality slider in Pixelmator Pro's export did nothing and that 100% quality files came out tiny. Exporting as JPEG or PNG avoids it.

Pixelmator Pro is pixel-based, so scaling a layer or text up stretches its pixels and makes it soft. Design at the final size, scale down rather than up, and sharpen last.

Pixelmator Pro opens PSDs, but Photoshop-only features like Smart Objects and some adjustment layers can't be read. They get flattened or shown differently. Simplify the PSD in Photoshop first, or export layered files from Pixelmator in Photoshop format.

Pixelmator Pro uses Apple's built-in RAW engine, so a new camera has to be supported by macOS (or by a Pixelmator update) first. Updating, or converting to DNG, fixes most cases.

Remove Background works only on a selected image layer. It's greyed out for groups, shapes or text, and on a group it hides the background with a mask instead of deleting it. Select a single pixel layer, or convert the layer to pixels first.

Warp and the premium mock-ups are exclusive to the Apple Creator Studio version of Pixelmator Pro (4.x). The $49.99 one-time Mac App Store version doesn't have them, and there's no paid upgrade.

Pixelmator Pro for iPad needs iPadOS 26 or later and an active Apple Creator Studio subscription. Most problems come from an expired subscription, an old iPadOS, or a damaged file. Restart, update, and reinstall after backing up.

The Pixelmator Pro extension doesn't appear under Image > Edit With. It's under Edit > the Extensions (three dots) button inside Photos. If it's missing there too, update Pixelmator Pro, since past versions broke the extension.

ML Super Resolution, Denoise and Enhance rely heavily on the GPU and Neural Engine. On Intel Macs or patched older Macs they can fall back to the CPU and become very slow. Apple silicon Macs run them many times faster.

Generate Image, Generate from Image and Generate Shape (added in 4.3, June 2026) only work in the Creator Studio version, on a Mac with Apple silicon running macOS 26 with Apple Intelligence available.
