[QUOTE="krs, post: 1850720, member: 67742"] Thanks Randy, I remembered that those instructions were posted on this forum before, but trying to find them is not easy. I'm going to start making my own reference file for ver useful items like that. I haven't tried those instructions yet because last night as I was going to sleep I thought that maybe just resetting the date on my Mac might possibly do the trick. But then, on the other hand, I thought that it couldn't possibly be that easy and Apple would be smarter. However, Apple is rather sneaky here - the message that comes up is that the installer is corrupted (which in fact it isn't), but with a "Corrupted" file, people would just either try to repair it or trash it. But since I learned-through this forum -that this error messages just comes up when the certificate on the installer is expired, I figured setting back the clock on the Mac is worth a try - and sure enough - that works as well! I wonder if anyone else installed macOS that way, by resetting the clock, installing the OS, and then setting the clock properly again. I'll try the "delete InstallInfo plist" later today - once Mojave is installed on my external SSD I want to transfer everything from El Capitan to Mojave and that would probably take a few hours so I want to do that over night.
