@merill Been trialling it on a few Macs, works well apart from the last step where it's trying to sync local password. The final credential popup hits /usernamemixed on our ADFS which fails when a user is set for MFA. The Platform SSO setup completes and SSO works throughout Safari, Office, etc. but I just keep getting the "Authentication Required" pop-up.
The only option I can think of is some tricky ADFS wizardry to except the AppSSOAgent user agent from MFA, which isn't too secure
