How to fix the problem The installer checks the date on the computer. If the date isn’t current, you get the error above. The fix involves correcting the date on your Mac. If you have an older OS on the Mac If you have a complete OS on the Mac already, boot into it. Fix the date in the Date & Time system preference (Apple menu > System Preferences). Reboot using the USB boot disk, and you should be able to proceed with the installation. If you don’t have an OS on the Mac If you are in a situation like I was, and you don’t have a complete OS on your disk (you reformatted it), you’ll find that there’s no way to access the Date & Time system preference when you use an external USB boot installer drive. The Apple menu doesn’t give you access to System Preferences. You have to use the Terminal to set the date and time. osx boot install error terminal How to access the Terminal when you boot from an external boot drive installer. If you use an external boot disk, you Mac starts up into OS X Disk Utilities. You can access the Terminal by clicking on the Utilities menu and selecting Terminal. Once the Terminal has launched, follow these steps.
