I've been trying to upgrade my Mac from High Sierra to Mojave, but I keep getting the error below.
I rang Apple support and they told me to wait a while and try downloading it again from the App Store. I've now done this 2 times and continue to get the same error.
I spoke with Apple again and they said to wait a while and try installing it again. It's now been two days and I've rebooted my Mac a number of times, and have attempted installation many times.
I also tried installing all other software updates in case that was a factor. They all updated fine without any problem. The only thing I can't do is get the Mojave installer to run because it is apparently "damaged".
Maybe this is the universe telling me not to upgrade and I should give up, but now I'm here to ask you good folk.
Can someone kindly suggest other options for me?
