Microsoft Skydrive sync problems on Mac OS

I recently updated my Skydrive to the newest version on Mac OS X. I am using 10.8.3 (Mountain Lion). However, I came across a sync issue with Skydrive. The program seemed to stop working, the Skydrive Icon was only gray. I then looked at the forums and it turned out that this is due to a verisign host header entry. To solve this issue, simply do the following:

1. Start the Terminal. You can get there by opening the Launchpad and type “Terminal”

Nano edit a host file on OS X 10.8 (Mountain Lion)
Nano edit a host file on OS X 10.8 (Mountain Lion)

2. In the terminal, run nano (the editor for OS X). It needs to have additional rights (sudo). Start nano with the hosts header, with the following command:

$ sudo nano /private/etc/hosts

3. Scan the file for “” and comment that out by adding a # at the beginning of the file.

4. save the file and quit.

5. restart Skydrive and it should work again.
