This release is part of the sponsorship by ClearChat, Inc.. Initial release for Mac will be ready in about a month and will support Python 2.7 and wxPython. Schedule for support of Python 3 and other GUI frameworks on Mac platform, is not available at this time.

CEF v55 supports MacOS 10.7+, 64-bit only.
CEF v56+ supports MacOS 10.9+, 64-bit only.
CEF Python v31.2 was the last version to support 32-bit.

There was an issue with discovery of icudtl.dat (#304), thus v55 release for Mac was skipped. v55 could be built with OSX 10.7+ support, but fixing icudtl issue would require patching CEF, so it wold require building CEF/Chromium from sources and that takes a significant amount of time. Current v56 release uses ready binaries from Spotify Automated Builds. See docs/Build-instructions for more details.
