My launcher won't open when offline. It keeps asking for the access for some keychain, and won't stop even when I allowed it several times already. And if I click always allow, it keeps opening and closing and opening, which makes it impossible to anything. The only way to solve this problem was to restart the computer or connect to the internet if it is available, which in most situations, is not. I tried reinstalling minecraft, and everything else I could think of. But nothing worked.
