Everyone Says: Check the System Time on Mac
Apparently, the system time on your Mac may be off causing the El Captain installer to think your system date is way off. This happens if your onboard motherboard battery is toasted. Check the date to ensure it’s right – follow these steps.
1. Cancel out to the installation (If you are still on your bootable image of El Captain). Go to Utilities -> Terminal.
2. Type date. If your date is correct, then proceed to the next section below. If it’s not correct, continue with these steps.
3. Set the current date and time. In Terminal, type the following command in this format shown in example below date MONTH(02)-DATE(28)-TIME(01:51pm)-YEAR(15)
