Now I create a admin in admin group, the screensaver program is still blocked when run.
OK. Thanks.2010/8/24 John R Pierce <pierce@hogranch.com>never EVER log in as root, unless doing emergency system repair, like when you are in single user mode because the system won't boot.
Yeah, I only use the root account, how to resolve it?
create a user account, with a password, use that for all regular purposes, and sudo or su to gain root access for specific commands that require it.
