I am unable to open Safari. The operating system on my MacBook Pro is Sierra 10.12.6. I have been told by Apple that if I download the latest OS I will not be able to access my Microsoft Office suite which is 2011. I am wondering if this is causing the problem. During the past several months Safari would completely shut down and a window appeared asking me for the password to access my computer. I appreciate any thoughts on this.

Will it open if you try to open it from the Applications folder?
Try setting up another admin user account to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.
Isolating an issue by using another user account
Thanks Eric. I tried oping from the Applications Menu and it still does not work. I also downloaded the newest operating system not caring if I lose the Office Suite. It still does not work. Perhaps my computer is just too old...2011!
You are welcome. The age of the computer shouldn't affect how Safari work. Did you try what dominic suggested? Have you tried another admin account or the Safe Mode?
