Make sure to optimize your Mac using a Mac cleaner to make sure your system is running smoothly.īut if you don’t have access to your macOS because it has been corrupted or you want to format the drive, then you can only use Terminal to get this information. If you still have access to your old macOS, you can easily check for the system time and settings by clicking the Apple menu > System Preferences > Date & Time. In this case, the above example would read 2512203020. In regions where the day of the month comes first, you switch the day of month and month of the year. For instance, 8:30 PM on Decemwould be formatted as 1225203020. In the U.S and other country in which the day of the month generally appears after the month, such as December 25, 2020, the format follows this sequence:įor single digits, a zero (0) is added before the number so that they are always two digits long.
You need the exact day of the month, the numeric equivalent of the month (1 to 12), the current time in hours and minutes using a 24-hour format, and the last two digits of the year. To correct the date and time settings on your Mac, you need to know your current date and time in order to format it for the command needed. If the date and time embedded in the certificate is set before the issuance date or after the expiration date, the encryption system will not accept it and the macOS installation spits out an error.

This is because the encryption system wants to check whether the digital certificate that proves the integrity of a piece of software has not yet expired. To make a secure connection, most encryption algorithms would require an accurate and updated clock.

This issue occurs when the Mac’s system clock is not set correctly, leading to a chicken-and-egg problem: without macOS installed, there’s no direct way to set the clock correctly, which would allow you to install macOS. If you’re getting the ‘untrusted_cert_title’ error when reinstalling macOS, you need to check whether your Mac’s date and time settings are correct.
