[QUOTE="IWT, post: 1771766, member: 83420"] Yes this will work, if you're quick about it:) Go to the App Store on your Mac > Updates and macOS Sierra should still be available. Download it. When the download has finished, stop things there. It should be in Applications. Move it to an External Hard Drive (EHD) or some other safe storage. It can then be replaced in Applications if/when needed. Moreover, as you've downloaded it, it will always be available in the Purchased section of the App Store. Another thing you could consider, is using Diskmaker X to create a bootable version of Installer macOS Sierra on a USB stick of at least 8GB capacity. The additional advantage of this is that you would not only have the Sierra download on an EHD, but in the future, you could use the bootable version to boot into your Mac, and do a clean install of your Mac; rather than just overwriting your existing OS.
