How to force MS SharePoint URLs to open in Safari when Chrome is set as default browser?
This worked for me!

Open Automator (usually found in your Applications folder)

Go to File &gt; New (or just press commandN to create a new item

Choose &quot;Service&quot; (it's the one that looks like a cog)

Select options based on the picture below
Note: To get the &quot;Run Shell Script&quot; part, just drag that option from the list on the left pane.

Save the service


Now the Service name will show up when you right click on a link, giving you the option to open URLs in safari.
