@jihan2011 I just figured it out on mac,

search for keychain access find Opera Safe Storage under access control allow all applications open Chrome Safe Storage under access control allow all applications
5.restart both browsers and log in click your log in letter/account on the top right of opera browser there should be first option sync syncronization click sync, sync everything, choose chrome Wallah!After that i wont go back and change those setting to not allow all applications just incase for safety so no sketchy applications get your password bank
