hdiutil convert /tmp/Mojave.dmg -format UDTO -o ~/Desktop/Mojave_10.14.4.iso

Apple distributes macOS only through its App Store and official installer channels. Downloading macOS from third-party sites as ISO files can be illegal or unsafe and may include malware. Use official Apple sources whenever possible.

For completeness, we acknowledge that pre-made ISOs circulate on The Pirate Bay, RuTracker, and nzbking. If you absolutely cannot use Apple’s official tools (e.g., no access to a Mac, no internet for softwareupdate), and you accept the risk:

Our legal recommendation: Borrow a friend’s Mac for 20 minutes to create the ISO using the Terminal method in Part 2. It is the only 100% safe route.
