hi OSX experts
my Mac Pro is still running Mavericks but with all patches and updates up to date. i recently noticed its Messages app no longer signs on Google Talk with my Gmail accounts and after troubleshooting I believe the issues is related to the "access for less secure apps" setting of my Gmail account.
once "access for less secure apps" is allowed, Messages can sign on and stay in Online status. once the access is blocked, Messages will prompt a dialog box asking for the password though the correct password has been saved in the keychain. obviously i do hope to keep blocking less secure apps but if so the Messages app no longer works actually.
is there anyone here having the issue? Any solution please?
