When I open safari on my iMac I get an error saying Safari is damaged and should be moved to the trash.
When I try to open safari by clicking the safari icon on my iMac I get an error stating safari is damaged and should be moved to the trash. However, when I click a link in an email it will open in safari and then the browser seems to work fine on that and other web pages till it's closed again. I've upgraded safari and restarted the computer...
