good day to all. I have a Mackbook Air running the latest Mojave’s os. Looking to make a backup of the os been thinking about making a bootable usb pendrive. Been looking on line for the method of achieving this challenge.First question is if I download the latest os from the App Store even though I have the latest installed,will the one from the App Store go to the download folder? If that’s correct I plan on using the Diskmaker software to make e bootable usb pendrive. Or would it be possible to get that latest Mojave’s os from another source. Many thanks.
