How do I find High Sierra? The one showing says I have to upgrade to the first one before I can upgrade to the latter?

Where is the Original High Sierra 10.13.1? It says I need to down load it first before I can download the latest version which is 10.13.6.

iMac, macOS 10.12

You must have the 10.13 Combo Updater, you need the full installer, which is 10.13.6...


Don't use FireFox or Waterfox for this link…

If you get a corrupted message...

Naw, not damaged, it's just that you have an old copy already in Applications, there are 2 cures...


Disconnect from the Internet & set the Date back to 2014, then you can run the Install MacsOS High Sierra App in Applications, so expired Certificates are not expired.


Or... trash the Install MacsOS High Sierra.app in Applications, empty trash & restart, then a new copy of a more recent version can be downloaded…

There is only one FULL VERSION of High Sierra offered by Apple and that is version 10.13.6


Anything else one finds are updates to an already existing and installed versions of High Sierra and are Not Full Versions of High Sierra


The Age of this computer will Govern what newer version of macOS it will Qualify to install. Use About this Mac from the Apple Icon on Desktop - the required Information will be there.


With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install.  For Best results use Safari to commence the download as Others may not work.


Safari will open a redirect and open the Apple Store where the download can commence


Make Time Machine Backup  is very useful and can be used to Revert to Previous Working macOS


Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal  operation of the OS and may even Corrupt the OS requiring a Reinstallation
