MacOS – How to downgrade the Safari from version 6.1 down to version 6.0.2 on the Mac

It appears to have been due to me having an older version of the 1Password Safari extension which had a bug with Mountain Lion. I thought I had the latest version because I had the latest version of 1Password installed, however to update the browser extension, you need to run the browser install again.

Open the Terminal app (found in /Applications/Utilties/).
Copy the following as one line (from “curl” through “.pkg”) and paste it into the Terminal window after the “$ ” prompt:

curl -O http://swcdn.apple.com/content/downloads/37/23/041-5058/lr5tynbldi18zcrqo8a8uq88 rnjushqliu/Safari6Lion.pkg

then hit return.

You should see it count down the time. When it stops, look in your home folder (the one with the little house and your user name) for “Safari6Lion.pkg”. Double-click to launch the installer.

Here is an alternative solution that seems to be working for several users, especially those who have somehow managed to install more than one WebKit framework:

1. Open Finder and navigate to: /System/Library/StagedFrameworks/Safari/ Drag WebKit.framework to the trash

2. Run software update and install Safari > do not launch safari after it is installed

3. Restart computer

4. Launch Safari

Let's try!
