I'm still running Mac OS 10.11 El Capitan. I've decided to upgrade, but I don't want to lose 32-bit support, so Catalina is not an option for me.

I found this official Apple page: https://support.apple.com/en-us/HT210190

However, the link on that page to download Mojave (https://itunes.apple.com/us/app/macos-mojave/id1398502828?ls=1&mt=12) doesn't work for me. (I have iTunes It only pops up a message from iTunes:

Item Not Available

The item you've requested is not currently available in the U.S. store.

How can I upgrade to Mojave?

  • I have a sneaky feeling you need to go via High Sierra before Mojave, for the firmware update & APFS prep. [but I can't confirm this for sure, nothing to test on any more] Also see apple.stackexchange.com/questions/309399/… which is getting a bit out of date now, but still might have some useful info.

    @Tetsujin that comment is so good, I’m editing it into both my answers on this.

  • @bmike - thanks for the edit on that - I'm losing track of it a bit these days as the newest Mac here is stuck at Mojave.

    We had thousands of Mac that could go to Mojave and didn’t (for reasons) at work so we’ve been doing this process over and over and over. I feel like I know every single thing that can go wrong updating from 10.9/10/11/12 to Mojave or whatever the latest aging hardware can do. With COVID we are squeezing life out of every machine we have. It would have been easier if people had backups and just upgraded each year. We have many that may never go to Catalina as well @Tetsujin

  • @Tetsujin nope, direct upgrade worked perfectly.

Open the link in Safari so that it finds the Mac App Store to open the application.

If you have failures after getting the Mac App Store to receive the link or the installer is too small or doesn’t work, this post is amazing and can help with different issues specific to machines and OS versions.

  • The AppStore reports this as being a 6.1 GB download. Is that the entire OS, or is this an installer app that downloads the actual OS binaries from another location?

  • At 6.1 GB it is the entire OS

    The entire OS does call out to the internet before installing for any late changes, firmware patches for the specific hardware it’s running on, but it’s a fully functioning OS that can install offline, @Seamus

    Boom, that does it! Thanks! Interesting because just choosing "Mac App Store" for the "open link with" from Firefox didn't work at all, but this approach works.

    Be sure to check the size of the installer when you download it to make sure it is the 6GB size. Apple has given me installer apps instead of full OS installers. But it was clear that it had not downloaded 5-6GB in the time it took to finish downloading from the App Store.
