Compatibility notes

The picker is currently not working on macOS High Sierra (10.13). We are aware of this problem and working towards a fix. Please do not update to High Sierra if you use Open Color Tools. We will publicly track progress on this on our public bug tracker on GitHub.

The picker has been tested on macOS Sierra (10.12), El Capitan (10.11) and Yosemite (10.10). As we’re using some features of a more modern Webkit/Safari within the picker, older versions of OS X are hard to support, even if possible in theory.

The picker currently only works in 64 bit applications. This is due to the fact that the current state of the art memory management style, called ARC, only works in 64 bit. Most applications are 64 bit nowadays, with one popular exception: Microsoft Office. If we’ll get enough requests to support 32 bit applications, we might consider it, but it’s somewhat of a daunting task and will make further development of the picker harder.

What does the installer do?

When you install the Open Color Companion the Open Color Picker also get’s installed. You can use it in almost any application to pick from the colors in the .oco files in your library.

The picker is some sort of small OS X application bundle (or rather something similar) that gets copied to your own ~/Library/ColorPickers/ folder.

How can I uninstall the Picker?

To uninstall the Open Color Picker, you can safely delete the file BrandColorPicker.colorPicker from the ~/Library/ColorPickers/ folder. To go there, you can Press CMD-Shift-g (or use the “Go to Folder” menu item) in the Finder and enter the path ~/Library/ColorPickers/.
