Q: Is the “Mac OS X Lion 1072 dmg file fixed” legal? A: Yes – if you own a valid license. Lion was distributed for free to all Mac users via the App Store. If your Mac originally shipped with Lion, you are legally entitled to a copy.

Q: My fixed DMG mounts, but the installer says “Lion cannot be installed on this Mac.” A: Your Mac’s firmware blocks pre-10.7.5 builds. Use a tool like Lion DiskMaker to strip the model check, or upgrade your fixed DMG to 10.7.5 via a combo update before creating the installer.

Q: Can I use this DMG in a virtual machine? A: Absolutely. A fixed 10.7.2 DMG works perfectly in Parallels Desktop 19/20, VMware Fusion 13, and even UTM (with QEMU acceleration). Just mount the DMG, drag the app into the VM’s Applications folder, and run.
