We have just released the OneLogin extension for Safari 5. Besides being compatible with Safari 5, the new extension is also completely Javascript-based, which means it's more lightweight, more robust and simply easier to deal with in all aspects.

Uninstall old OneLogin extension

If you are using old OneLogin extension, you should uninstall it before proceeding. Using the Finder, go to /Applications/OneLogin and run Uninstall.

Upgrade to Safari 5

If you have not already upgraded to Safari 5, you can do so via Software Update in Mac OS X or by downloading it directly from Apple.

Install new OneLogin extension

To install the new extension, simply go to onelogin.com/downloads and download it.
