Built on a foundation of simplicity, Acorn eschews the outmoded "many palettes" design from yesterday's editors. Acorn presents a fluid new interface that will be familiar to users of Apple's iLife applications. Designed for simple editing, Acorn features flood fill, gradients, vector shapes, drawing and erasing tools, and more. It also brings a few new tricks to the table, including chaining filters and easy image and canvas resizing. From quickly adding text to an image to creating a new graphic with pixel-precise control to just sketching out ideas, Acorn is great for all kinds of image editing.
What is new in this release:
- Faster panning, brushing, fills, and just a general speed improvement overall. Acorn should feel more fluid, and we've even seen framerates over 160 FPS when brushing on a 2015 iMac 5k.
What is new in version 6.0.4:
- Oh hey did you notice that Acorn can now open up HEIF images taken by your fancy new iPhones when run on 10.13? Even Acorn 5 can do that, but who cares about that because you're running the obviously superior Acorn 6.
- Print changes: Acorn will now automatically scale down your image for printing if it doesn't automatically fit on a single page.
What is new in version 6.0.3:
- Fixed a crasher when dragging and dropping group layers from the layers list, when they contained shape layers.
- Fixed a problem when using the exclude path function.
- Fixed a problem where the Bias fields in the RAW image import window didn't allow you to enter a wide enough range of values.
What is new in version 6.0.1:
- Fixed a problem where filling a selection with AppleScript was using the wrong color.
- Fixed a crasher having to do with the Curves filter.
- Better notifications when you're starting the App Store free trial.
- Little SVG import fixes.
- Fixed an issue where initially opening multiple documents with the same dimensions and the system prefs to always show tabs was incorrectly sizing the window.
- Fixed an issue where you might crash when merging a group layer.
- Fixed a potential problem where Acorn could crash when registering.
- Removed some static libraries that weren't being used anymore. The net result is that Acorn is a smaller download now.
What is new in version 5.6.5:
- Fixed a bug where duplicated documents wouldn't get the correct bit depth set.
- Fixed a bug where selected text could show up in web export.
- Fixed a crasher when importing a RAW image in full screen mode.
- Fixed a bug where RAW images sent to Acorn via Photo's "Edit in Acorn" were not being saved back correctly. Note: if you are on the App Store version of Acorn, you will not get the RAW import window because of Sandboxing restrictions.
- Fixed a bug where an image would snap to the grid even though it was specifically turned off for that image.
- Fixed a bug where the TGA format wasn't always availabe for export.
- Fixed a bug where you couldn't clear the selection while a group layer was active.
- Fixed a bug where the Alpha Multiply filter wasn't being saved in the presets correctly.
- Fixed a crasher when using the Dither filter in combination with a gradient filter.
What is new in version 5.6.4:
- Fixed a(nother) problem where areas of the image would go black when running on macOS 10.12 Sierra.
- Fixed a problem where nudging a single selected pixel could fail on 10.12.
- Fixed a problem where deleting a magic wand selection would sometimes fail on 10.12.
