I seemed to have stumbled upon an interesting issue with Norton Security for Mac while administering a SharePoint site hosted by Microsoft. I can reproduce this issue at will on two different Macs and the end result is the same.
After logging into https://portal.office.com and selecting Sites from the list of applications I am brought over to my SharePoint site hosted at https://<site>.sharepoint.com. When I click on an image to add an app to the SharePoint site the browser (Safari or Chrome) rotates between a http and https version until a kernel panic happens. The detailed instructions and the subsequent kernel panic dump are attached to this forum posting.
Correlation does not equal causation but if I remove Norton Security from the iMac, the issue stops on the iMac but continues on the MacBook Pro. I have not had a chance to reinstall Norton Security back on the iMac yet to see if the problem persisted. That could very well resolve the issue. I thought I would post this here to see if anyone at Symantec might want anything from either workstation before I try to fix this myself.
