Error "CSSMERR_TP_CERT_NOT_VALID_YET" while install the OS Mavericks
Hello,
I am trying to install a fresh copy of OS-X Mavericks on my 13” MacBook Pro.
I did a bootable USB, but every time I tried to install the OS, it says : “impossible to verify this copy. It has been damaged, or altered during the installation. I tried a different USB, same issue.
So I went to the historic of the installation program. It says
Error : CSSMERR_TP_CERT_NOT_VALID_YET.
Would you have any ideas to help me to have an OS :)
Thank you for your help !
