Not a big deal, I switched to El Capitan today and things are working mostly alright to my surprise. One issue with my email has changed. Before EC using Mavericks I had an option under customize toolbar to add an icon called Addresses to be dragged into the tool bar of the mail program. Which allows me to click and activate my contacts list from that button. With EC there is no choice offered called Addresses from the customize toolbar to add that icon in the upper tool bar. Any help is appreciated . Thank You EC for not messing up my Apple Computer as it did for some folks. Just the mail issue that is causing me to add each email recipient one at a time. Hope there is a fix for this situation.
