Apple does not provide official direct download links for macOS ISO files, as they distribute installers via the Mac App Store or as DMG files . To obtain a 64-bit ISO, you must typically download the official installer on a Mac and convert it manually using Terminal or third-party tools like Mist . Official macOS Download Methods You can download installers for various 64-bit versions through Apple's official channels: App Store (macOS 10.13 to current): Use the App Store to find versions like High Sierra , Catalina , Big Sur , and Sonoma . Web Browser (macOS 10.7 to 10.12): Apple provides direct DMG installer links for legacy versions like Lion , Yosemite , and Sierra . Terminal: On a Mac running Catalina 10.15 or later, use the command softwareupdate --fetch-full-installer --full-installer-version to download specific versions directly to your Applications folder. How to Create a 64-bit ISO on Mac If you need an ISO for virtualization software like VirtualBox or VMware, follow these general steps in Terminal after downloading the installer: Create a blank disk image: hdiutil create -o /tmp/macOS -size 14G -layout SPUD -fs HFS+J . Mount the image: hdiutil attach /tmp/macOS.dmg -noverify -mountpoint /Volumes/macOS . Flash the installer: Use the createinstallmedia tool found inside the downloaded .app file to copy files to the mounted volume. Convert to ISO: Unmount the volume, then convert the .dmg to a .cdr format using hdiutil convert , and finally rename it to .iso .

Downloading a 64-bit macOS ISO is primarily done for use in virtual machines (like VirtualBox or VMware) or for creating bootable installation media.

Official Download Methods (DMG/App Store) To ensure security and avoid malware, always start with official Apple sources. Mac App Store: The primary method for recent versions (e.g., macOS Sequoia 15, Sonoma 14). Use Apple Support direct links to open specific versions in the App Store. Web Browser (.dmg): For older versions like Yosemite 10.10 or Sierra 10.12, Apple provides direct disk image downloads . Terminal Command: On a Mac running Catalina or later, you can download specific installers using this command: softwareupdate --fetch-full-installer --full-installer-version [number] (e.g., replace [number] with 14.6.1 for Sonoma). 2. Creating an ISO from the Downloaded Installer If you need an actual .iso file for a virtual machine, you must convert the downloaded installer app or DMG. Download the installer to your /Applications folder. Use Terminal to create a blank disk image, mount it, and use the createinstallmedia tool (included within the macOS installer) to copy the installation files. Convert to ISO: Once the bootable image is ready, use the hdiutil command in Terminal to convert the .cdr (or .dmg ) into a standard .iso format. 3. Alternative/Third-Party Sources
