My 2010 27” iMac got bricked a few upgrades ago. I’d like to wait until the second ARM cycle before upgrading my 2013 MBP. I miss being able to pull a CD off

My 2010 27” iMac got bricked a few upgrades ago. I’d like to wait until the second ARM cycle before upgrading my 2013 MBP. I miss being able to pull a CD off the shelf and doing a fresh install.

You can do a clean install on modern Macs using USB media: https://support.apple.com/en-us/HT201372 https://support.apple.com/en-us/HT201372

  What’s more you can setup multiple versions of the installer on one drive and it’ll show you the installer icon for each one at the boot select screen (I can’t say I’ve added Big Sur to my installer drive but the previous three work this way)

  For vintage products, restoring to factory settings often has to be done through torrents or Github. Other then that no complaints.

    How vintage is vintage? Internet Recovery was added in 2011 [0] — although it doesn’t work in all cases. If you have older hardware (as old as 2007), you can download Yosemite, El Capitan or Sierra from Apple’s website [1] or the App Store. Note that using those images requires access to a working Mac, or at least a Mac with working (Internet) Recovery, although doing it in Recovery is complicated and requires some tricks [2], because Apple can’t just make a simple DMG you could mount (or image a drive with) and install directly.

  Or even from the internet with no media at all.

  Not if you want to downgrade your OS version.

    Do you mind elaborating? I've upgraded my late 2013 MacBook Pro to Catalina, then downgraded back to Mojave just fine.

      Didn't Mojave convert HFS+ to APFS? I don't think that would work with (High) Sierra or older.
