Install macOS Sierra.app is not in Applications folder
I'd love to make an external boot, but somehow do not have the Install macOS Sierra.app in my Applications folder. I’ve done all the usual troubleshooting, to no avail. It’s not hidden, I’ve re-downloaded, started in safe mode, etc. I need the install app in order to create my boot drive. Any ideas why I don’t have one? Every OS previous to this has had the install app in the Applications folder, but somehow Sierra doesn’t.
