I just used the upgrade button to put CE 3.0.2 on my Mac running 10.11.6. Now, I cannot run CE. The icon is greyed out, and when I attempt to click the sign in option, the icon disappears and I cannot go any further. I did not have any problems with 2.9 (the last version I had on this computer). Further, now I am having connectivity problems to websites like my bank, that I did not have before. Any suggestions?
