I am trying to upgrade my 2014 macbook air to high sierra or mojave. the links in the article take me to the download page in the app store, but when I click download, nothing happens. what is the issue?
MacBook Air
Instead of using WiFi it is sometimes best to use a cabled connection from your mac to your router.
Have you restarted your mac in-between attempts.
Have you tried downloading while in Safe Mode.
How to use safe mode on your Mac – Apple Support
Safe mode takes a long time to start up, be patient.
When the app store opens, it says download. When I click download, it tries to start and then it stops. Then the download button greys out. I'm not sure what you mean by connecting to my router via cable. I was able to download the installer for catalina just fine, (so I don't think it's a router issue) but I am more comfortable using mojave or high sierra on this older machine.
When the links to the App Store open for each OS what does the page say do they say Get or Download,
or do they say Open.
If the App Store download page says Open then the App Store has detected a copy of the Install macOS High Sierra/ Mojave.app
which you will find in your Applications folder.
If the App Store download page says Get or Download and you press that and nothing happens
is your mac connected to your router via cable, this is always best when downloading from Apples servers.
Are you using safari to open the download link from the support article?
Check if you have any existing macOS Installer downloaded in applications folder. This may prevent to download a new copy.
Thank you. No existing installers in the applications folder. But the problem is persisting.
Look for an Install macOS High Sierra.app or Install macOS Mojave.app elsewhere on your mac
or any any connected external drives.
Can you share screenshots of the errors you are seeing.
Thank you. I have restarted several times and attempted the download while in safe mode. I will try using a cabled connection when I get a chance and see if that works.
high sierra and mojave downloads don't work
