I am prepping my 2015 MacBook to return for trade on new M1 Air. I have erased the drive using Disk Utility and then used the MacOS Utilities to reinstall MacOS Catalina. I have followed the support instructions precisely and run the reinstall MacOS utility twice. Each time I get the error message “Could not create a preboot volume for APFS install”.

Disk Utility shows Macintosh HD as an APFS Volume with 2 Disk Image Volumes: macOS Base System (Mac OS Extended) and InstallESD (Mac OS Extended) The Macintosh HD volume is 250.69 GB, with 15.99 GB used and 232.95 GB free. The disk image volume macOS Base System shows 2 GB total with 1.35 GB used and 658.4 MB free. The disk image volume InstallESD shows 7.89 GB total with 7.77 GB used and 120.6 MB free.

Reinstall Mac Os Catalina From Big Sur

I've already got the new MB Air and the return mailer for the trade. How do I fix this?

Reinstall Mac Os Catalina Without Losing Data

Once you’ve restored your settings and reinstalled all the apps you need, your Mac is ready to use again, running Mojave instead of Catalina. Tip: If you want to roll back to an earlier version of macOS than Mojave, you can. To reinstall the OS your Mac shipped with, use the method in ‘How to downgrade if your Mac shipped with Mojave’. When it’s time to install a new version of macOS or download a new update, nearly everyone turns to the Mac App Store to start the process. While the App Store makes OS installations easy.

Reinstall Mac Os Catalina

• When Disk Utility has finished erasing the disk, quit it to return to the macOS Utilities screen. Choose Install macOS. Press Continue and choose the drive you just erased and re-formatted as the destination. MacOS Catalina will start to install. When it’s finished, your Mac will restart and it will look like a brand new Mac.
• Step 4: Reinstall macOS Catalina After you have erased your hard drive, you will want to reinstall Catalina. NOTE: If your Mac came with macOS Catalina, you can restart your Mac while holding down Shift-Option-Command-R to enter Internet Recovery Mode and install the operating system that came with your Mac.
