Conditional Access App Control and OneDrive on macOS

[Julian Rasmussen]

I`m having issues within one of my customers where when i have enabled Conditional Access App Control for all Cloud app`s - the macOS users are getting problems with authenticating on OneDrive for Business. 

When trying to authenticate the application just throws back a error message "Problem connecting to OneDrive" and gives me option to quit OneDrive or try again. 

When disabling my Conditional Access thats forwards sessions to MCAS the authentication goes OK. 

Anyone else noticed this behavior?

Hi Julian, I'd be happy to help you troubleshoot this. Are you able to grab a fiddler trace of the authentication with Conditional Access App Control turned on and email it to me (alex.esibov@microsoft.com)?

Sweet! Thnx Alex. But one more thing then.. Anyone familiar with the use of fiddler on macOS? 

or is there any other tools i can use instead of fiddler?
