# I'm on the most recent public beta and am having the following issues after a clean install with nothing but Chrome added to the default programs on a Macbook Pro 13in Retina from 2013. Mail app is unusable. Crashes randomly during use when scrolling through emails or clicking on emails to view. Safari is also completely unusable for me. After a few minutes it completely locks up. Swiping up and down there is a several second delay (So I swipe and 10-15 seconds later the swipe registers on the screen. It often times locks down my entire system so while safari is open I can't use the rest of my Mac until I force close Safari). Chrome is giving me no such problems so it's gotta be something with Safari. Anyone else experience this at all? Wouldn't even know where to start in troubleshooting it since I've already clean installed it to determine if that was the issue.
