I have a 2015 MacBook Pro 13". I have OSSierra 10.12.6. I want to install latest Autocad LT but it requires 10.13 at least.
I read the post of Scberry66 from 2018 and replies about upgrading to High Sierra from Sierra. I have tried unsuccessfully to install High Sierra 10.13.6 because the laptop requires 10.13 first. This version (10.13.0) I cannot find. In 2018 people made many suggestions to Scberry66 but none work now. The App store page for High Sierra does not have any download button. The support page recommends going to 10.15. Catalina is incompatible with some of the programs running on my laptop that work with Sierra. Any help out there please

What you downloaded was the updater to go from 10.13 to 10.13.6. To get High Sierra, go here: https://support.apple.com/en-us/HT208969
this will download 10.13.6.
i would personally go to Mojave, however.

Agreed. See no reason not to go to Mojave. Anything that runs on High Sierra should run on Mojave as well, still supports 32-bit software and will give a newer OS with longer lasting security support

Thanks, I'm downloading Mojave right now. The reply from chrfr was the same he/she replied to the original poster in 2018. But as the 2018 poster responded this DOES NOT WORK. The laptop won't allow 10.13.6 to be installed unless 10.13 already exists.

That's incorrect. What I linked is to a full 10.13.6 installer which will install even if there's no operating system on the computer.

OK it may have worked on your computer but on mine it didn't numerous times. I've downloaded and installed Mojave instead.
I also downloaded Mojave from the App Store to my wife's MacBook and when trying to install, the message was that it was damaged. So again I will have to try to get an undamaged download. Not happy Apple.

thanks all for your help.
 
What year is your wife's MacBook?

Something to try (on her MB):
Assuming that you still have the Mojave installer in the applications folder, do this:
1. Open date & time pref pane
2. UNCHECK the option to "set date & time automatically"
3. SET BACK THE CLOCK to January 1, 2018
4. REBOOT
5. Try running the Mojave installer again.
6. If it works this time, do the install, then "restore" your settings in "date & time".

This will hurt nothing, and may coax the install into going through.

This will work if you use the downloaded installer app to create a bootable installer on an external drive. For Mojave, that can be an 8GB USB flash drive. 8GB is not always in the local shops, so 16GB would be fine for that.
Apple has a support page with steps to make that bootable installer through your Terminal app. If you are challenged by the Terminal, then there are several apps that make that task easy, such as DiskMakerX, or Install Disk Creator.

When you have the bootable installer, you can then install on whatever Mac you have that supports Mojave, for example. No more need to download on each Mac that you want to upgrade, just boot to the external drive.

This is correct - date and time needs to be rolled back in order to install older OS.

I use Terminal to change the date & time.

Next step: make a bootable installer from your next macOS installer download.
