Trinity Helper (Renderer)

Previously, I have had no problem opening Trinity on my Mac and after providing my password, it opened correctly. I updated after the recent closure and again, all was satisfactory. I have not used IOTA for a while, but I attempted to open it yesterday and received a message “Trinity Helper (Renderer) wants confidential info from my Trinity Wallet in my keychain and requires “login” keychain password. The only key I originally had was the one given to me for the seed vault, but this password was not accepted. If I click on “Deny” in this box a page opens stating error opening Trinity and now I cannot access IOTA. Any suggestions as to why this message is now appearing and how to resolve the issue.
