Change Date Terminal Mac El Capitan

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Once you’ve done that, here’s how to install, reinstall, or upgrade to El Capitan, step by step: Boot from your Recovery HD partition by restarting your Mac while holding down the Command+R keys. The OS X Utilities window appears. Select Reinstall OS X, and click Continue. The OS X El Capitan splash screen appears. To change the date from Terminal (which is likely all that will be accessible), follow these steps, which set it to 1 February 2016: In the installer, choose Utilities Terminal. Enter sudo date, press Return, and enter your password. Quit Terminal and continue the install. In short once you are at the first install page go to tools in the nav bar and open the terminal, in the terminal type date MMDDHHmmYY replacing the letters as follows. MM - 2 digit month 01 - 12 DD - 2 digit date 01 - 31 HH - 2 digit hour 01 - 24 mm - 2 digit minute 01 - 59 YY - 2 digit year 15 once that is done go through the install normally. It is (weirdly) controlled by two keys: com.apple.autologout.AutoLogOutDelay. You have to set both for it to appear correctly in the System Preferences (which you also have to quit and relaunch to get it to pick up updated settings). To view the current setting (if there is one). Made a bootable El Capitan USB. Press Option key and boot from El Capitan USB; Go to Utilities, Open Terminal, set date to, (that is July 06, 2017 at 10:50am; date is set about over 2 years prior current date, I just pick a random day in mid 2017 as suggested by Charlee78), exit Terminal.
