I am attempting to download High Sierra via a MacBook Air (Retina, 13-inch, 2019) onto a USB so that I can boot from a USB and get my Late 2011 Mac Book Pro to come back to life, with a new hard drive, and then use migration assistant to move the data I'd like to keep from my back up. Testing conducted by Apple in October 2020 on production 1.4GHz quad-core Intel Core i5-based 13-inch MacBook Pro systems with 8GB RAM, 256GB SSD, and prerelease macOS Big Sur. Systems tested with WPA2 Wi-Fi network connection while running on battery power, with display brightness set to 12 clicks from bottom or 75%.
Hi I was wondering if anyone can help me with an issue I currently have with my mac book air?

I am trying to download 'Microsoft One Note' onto my MacBook Air but it won't seem to let me. It keeps coming up with an error message;
'We could not complete your purchase. (null) can’t be installed on “Macintosh HD” because OS X version 10.10 or later is required.'
I have however downloaded and installed the 'macOS High Sierra' recently.

To get the latest features and maintain the security, stability, compatibility and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.
Find out how to upgrade to macOS Big Sur, the latest version of macOS.
Check compatibility
If a macOS installer can't be used on your Mac, the installer will let you know. For example, it may state that your Mac doesn't have enough free storage space for the installation or that the installer is too old to be opened on this version of macOS.
If you want to check compatibility before downloading the installer, find out more about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan or Yosemite. You can also check compatible operating systems on the product ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini or Mac Pro.
Make a backup

Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Find out how to back up your Mac.
Download macOS
It takes time to download and install macOS, so make sure you're plugged into AC power and have a reliable Internet connection.
These installers from the App Store will open automatically after you've downloaded them:
- macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite or Mavericks
- macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks or Mountain Lion
- macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion or Lion
Your web browser will download the following older installers as a disk image called InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It will install an app named Install [Version Name]. Open that app from your Applications folder to start installing the operating system.
- macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion or Lion
- OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion or Snow Leopard
- OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion or Snow Leopard

Install macOS
Follow the onscreen instructions in the installer. It may be easiest to start the installation in the evening so that it can be completed overnight, if needed.
If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.
