Lion DiskMaker 2
Lion DiskMaker 2 is a utility for macOS that creates bootable USB drives or external hard drives containing Mac OS X Lion (10.7) installation media. It is designed to help users who need to reinstall or perform a fresh installation of Lion on their Macs, or to create installation media for distribution. The tool automates the process of preparing external media with the appropriate Lion installer files, bypassing the need to manually copy installer data to removable media. It was primarily useful during the Lion era (2011-2012) and in the years immediately following for users maintaining older Macs.
AI Recommendation
1 suggestionLion DiskMaker 2 is an obsolete utility designed to create installation media for Mac OS X Lion, released in 2011. The app has not been updated in many years and serves no practical purpose on modern Macs — Lion itself reached end-of-life in 2014, and any modern Mac running this tool would be unable to boot a Lion installation even if you created the media. There is no native Apple Silicon build and the app will stop functioning entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). You can safely uninstall Lion DiskMaker 2 from your system. If you actually need to create bootable macOS installation media for a current macOS version, use the built-in createinstallmedia command-line tool (part of the OS itself), or third-party tools like DiskMaker X (a spiritual successor that supports modern macOS versions) or the official macOS installer app downloaded from the App Store.
