Sorry missed this, can’t download from updater, but it’s direct from Apple as guide in tonymac.
it’s El Capitan. I’ve tried dates, I’ve tried reassembling the installer..downloading the installer many times..I’m at a loss!
I just want to update to a newer os than Yosemite, but I was on chameleon not clover...could that be a problem?
many thanks, I really can’t work this one out!
