Mail - mail starts fine, but soon goes into a hang state especially receiving an incoming message. Only way out is to Force Quit and restart for another short period. This is probably the single most annoying issue with Beta 2.
Mail system hangs
Can confirm this problem with Beta 2.
same here.
confirmed.
Some others told about no Problems with Mail, maybe they have made a Clean Install instead of an Update.
My Installation is an Unpdate from 10.13.6 DP1.
Since Beta 4 everything seems fine again.
