Since Mac OS X 10.7 "Lion" is a legacy operating system, obtaining and using its ISO image today is primarily for virtualization (like VMware or VirtualBox) or reviving vintage hardware. 1. Executive Summary: Mac OS X Lion (10.7)
Mac OS X Lion, released in July 2011, marked a significant shift in Apple's ecosystem by introducing features from iOS to the desktop, such as Launchpad and Multi-Touch gestures. It was the first version of OS X to be distributed via the Mac App Store rather than physical media, making the creation of a standalone ISO image a manual requirement for power users. 2. Official Availability and Legitimacy
While Apple originally sold Lion for $29.99, it is now officially free to download for users with compatible older hardware.
Official Download: You can download the Mac OS X Lion Installer directly from Apple Support. This download provides a .dmg (Disk Image) file, which must be converted if you specifically need an .iso.
Alternative Archives: For those unable to use the Apple installer, community-maintained mirrors like the Macintosh Repository or Archive.org host pre-made ISO images, though these should be verified for integrity. 3.

Security updates ceased in 2014; fully unsupported as of 2019. 4. How to Create an ISO from the DMG
If you have the official .dmg file from Apple, you can convert it to a bootable ISO using the Terminal on a modern Mac:
Mount the DMG: Double-click the downloaded file to mount it.
Convert to CDR: Run the following command (replace [path] with your actual file path):hdiutil convert [path]/InstallESD.dmg -format UDTO -o ~/Desktop/Lion.cdr Rename to ISO:mv ~/Desktop/Lion.cdr ~/Desktop/Lion.iso 5. Critical Usage Notes
Security Risk: Because Lion has not received security patches in over a decade, it should not be used for web browsing or handling sensitive data.
Modern Compatibility: Lion cannot run on modern Apple Silicon (M1/M2/M3) Macs natively. It is best used in VirtualBox or VMware Fusion on older Intel Macs. macOS 10.07 Lion - End of Life - SCS Computing Facilities

Auto Save & Resume: Apps automatically save work in progress and reopen exactly where you left off when restarted.
AirDrop: Allowed for wireless, peer-to-peer file sharing between nearby Macs without needing a Wi-Fi network.
Mac App Store: While launched just before Lion, it was fully integrated as the primary way to download and update software.
Skeuomorphic Design: Characterized by realistic textures, like the leather-bound look in the Calendar and Contacts apps. Official Installer & ISO Details

It's important to clarify: Apple has never officially released macOS (or OS X) Lion as an ISO file.
Apple distributes its operating systems as:
So if you see a file called "Mac OS X Lion.iso" on torrent sites, forums, or file-sharing platforms, it is unofficial — either a user-converted DMG → ISO or a modified/cracked version. Such files are often unsafe (malware risks) or non-bootable.
The Mac App Store downloads a specific installer app (Install Mac OS X Lion.app) that is designed to run on a Mac. So, why do people specifically want an ISO file?
Released in July 2011, Mac OS X 10.7 Lion was a watershed moment for Apple's desktop operating system. It marked the point where macOS began to heavily borrow aesthetics and functionality from iOS, bridging the gap between the phone and the computer.
