Mojave last version 10.14.6.06 download link (should open in all country Mac App Stores):

For those who forgot to grab before the surprise release of Catalina, who may want the last version for possible future re-use (on a USB stick I still have Mav/Yo/El Cap/Sierra/Hi Sierra/Mo ...just in case!).

If your Mac includes the Apple T2 Security Chip, booting from external drives is disabled by default, so your bootable SuperDuper! backup won't work. Here's a link to an Apple article that tells you how to change this so you can boot an external drive: https://support.apple.com/en-us/HT208330
