I realized yesterday that I could not see authentification pages of some WIFI. I'm running High Sierra 10.13.
Apparently to solve this issue I have to go to Keychain Access > Preferences > Certificates => disable OCSP and CRL.
The problem is that "Certificates" panel doesn't exist anymore.
Some people said that I had to find an old version of keychain.menu (TimeMachine's backup) but I don't have an old backup.
Could someone please update their old version of keychain.menu or help me one way or another to disable OCSP and CRL?
Thank you very much
