Warning SUID file System/Library/CoreS has been modified and will not be repaired
Hi,
I'm receiving this error message when I run disk utility, "warning SUID file System/Library/CoreS has been modified and will not be repaired" does this look familiar to anyone, or, can anyone help me fix this. The behavioral problem I'm having is putting my computer to sleep.
Thanks
