Acorn for Mac

Overview

Acorn is a user-friendly image editor that balances ease of use with a strong set of tools. It’s inexpensive and approachable, aimed at people who want more capability than a simple hobby app but don’t need the full complexity of Photoshop. If you find Photoshop’s many menus and advanced features overwhelming, Acorn can be a satisfying middle ground.

Who benefits from Acorn

• People seeking straightforward image editing without a steep learning curve.
• Users who want layer-based editing, vector tools and filters but not advanced professional workflows.
• Those who appreciate a clean interface and pressure-sensitive brush handling for natural-feeling strokes.

What’s new in version 4

Acorn 4 expands on the previous release with several notable additions:

• New layer style options and an improved Quick Mask for more precise selections.
• Instant Alpha (similar to a magic eraser) for fast background removal.
• A generally smoother user interface that keeps tools accessible and uncluttered.

Key features

• Vector drawing capabilities alongside standard bitmap editing tools.
• Pressure-sensitive brushes that respond realistically to tablet input.
• Easy layer management: add or remove layers quickly using simple controls.
• Common editing tools such as smudge, rotate, resize, merge, and the ability to make a single color in a layer transparent.
• A variety of filter and adjustment options to achieve high-quality results.

Known limitations

• Not a drop-in replacement for Photoshop: advanced power users will find some tools and workflows missing.
• No built-in iCloud syncing, which may be inconvenient for people who rely on Apple’s cloud storage across devices.

Recent fixes and enhancements

• Resolved an issue where .acorn files saved from the App Store version were not always written correctly.
• Updated the Vector Boolean libraries to address problems when combining shapes.
• Corrected a bug that prevented all selected layers from being copied when dragging them into another canvas.
• Changed filter preset behavior so holding Shift now adds the preset to any existing layer filters.
• Fixed a visual update problem where selecting a new filter preset didn’t refresh the preview if another filter was already active.
• Prevented an unnecessary dialog from appearing when an AppleScript trim operation found no transparent pixels to trim.
• Restored the ability to change the color of a selected range inside a text box.
• Fixed the Levels tool so it operates correctly with non-rectangular selections.
• Corrected the Exclude Paths operation so it behaves properly with overlapping vector shapes.
• Fixed an issue where the levels histogram failed to render correctly on some MacBook Air models.

Suggested alternative

If you need a powerful free option, consider Inkscape — a capable, no-cost vector editor that complements Acorn for tasks that require more advanced vector work.
