iMac 2007/2008 This copy of the Install OS X El Capitan application can't be verified. It may have been corrupted or tampered with during downloading.
i got this error when reinstall OS X El Capitan from bootable usb created from my MacBook. is this due to date issue that apple no longer support the old iMac? but I didn't connect to wifi or network. I already change my mac time to 2013 anyway.
