The OS X Upgrade/Recovery USB Drive is designed for Mac operating systems, specifically for versions 10.15 Catalina This flash drive is a convenient and reliable way to upgrade or recover your Mac's operating system. Perfect for those looking to ensure the smooth running of their Mac's operating system. I used it to carry out a recovery on my iMac which was a late 2013 iMAC running Yosemite 10.10.5 and put it back to macOS Catalina 10.15.7
