Setting up xpra for client use in OS X

Now (as of March 2016) available via 'brew install Caskroom/cask/xpra'

The most usable version on OSX is via gtk-osx, you can follow the build instructions for winswitch (aka shifter) here but skip some steps if you want:

• Requirements: yes, you need that
• jhbuild: yes, that's what will install gtk-osx
• gtk-osx: the OSX native GTK port
• GStreamer: skip this (not used by Xpra)
• ige-mac-bundler: skip this (not going to build an installer)
• Python dependencies: skip this - not needed by Xpra
• Build Protocol Support: Yes, just follow the xpra instructions

After that, your "jhbuild shell" will contain an xpra installation ready to use: the python scripts it has created should be on your PATH.

Alternatively, you can try with the version of Python shipped with OSX, but I don't know how well that works, if at all... The page linked above also has a link to the macports build version (you may skip the unnecessary steps which will be similar to the ones above)

Edit: the latest version also includes a PKG installer.

You can use Homebrew with a user-supplied tap:

$ brew tap victor-ono/homebrew-xpra
$ brew install xpra
