Trying to download high sierra on my macbook air and getting This update requires mac OS version 10.13

If the message says update, it sounds like you are trying to download an update rather than an upgrade.

Try it from here:

Get macOS High Sierra.

Naw, not damaged for real, 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 then a new copy can be downloaded.

It may not be compatible with your Mac, do you meet the system requirements, specifically date and year?

Check compatibility:

Those are Combo Updates.

Trying to download High Sierra 13.0 and receiving the following issue from Apple Store, This copy of the install MacOS High Sierra application is damaged & can't be used to install MacOS...I tried it many times...Any thoughts on a work around? Many Thanks!

BDAqua,

Sincere thanks for help! I did as you mentioned using second option....I could not find the link for the first High Sierra 10.13 but I did find HS10.13.6...Now I get, An error occurred while preparing installation, try running again. I have done this several times and I get the same error. Your thoughts? Also, I could not find a link with the pure & first release of 10.13. Your thoughts on both issues? As you know, it says that you must have 10.13 before you can upgrade to the Catalina version. Your thoughts on both?

Thanks, man! I worked for 2-hours trying to update my wife's computer. ****** me off that they would do something that stupid. I would have never thought of an old version in applications, but there it was. Thanks again.

Clicking onGet macOS High Sierra results in "not available in app store.

iTunes cannot find the macOS 10.13 in the Apple Store. The 10.13.2 and 10.13.6 updates will not run unless 10.13 is installed. Please help.

I'm eternally grateful!

You're welcome... you'd think error reports would be more meaningful.

I cannot download WORD because it requires a 10.13 Os but mine is only 10.11. How do I get WORD then? Thank you

I need to install High Sierra from scratch to a MACBOOK Air that previously had High Sierra installed. I can't download a new OS from Apple web site. Two files disappeared while attempting to remove files to make room for an update to macOS. What I need to is format the SSD (128GB)and install from scratch.
