Well, I was hoping for some more bug fixes in Beta 5. Wow, was I disappointed. Here is what I have found so far.1. Setup User account still shows up for a Windows Domain joined machine after upgrade.2. Outlook 2016 still crashes on startup if connecting to Exchange account.3. Mark as NOT junk button still missing from Mail.app.4. Safari fonts and rendering still has issues.5. Spotlight still sluggish when first opened.And that's in the first 10 minutes. If (when) I find more I'll post them here. All bugs listed have been logged as bugs with Apple.
