Despite being several iterations behind, macOS 10.15.7 (Catalina) holds its ground for specific use cases:
Never download a pre-made ISO from a third-party file-sharing site (Mediafire, Mega, Torrents). Instead, download the official installer from Apple and convert it to an ISO yourself. It takes 10 minutes and guarantees safety.
Now that you have a verified, freshly created macOS Catalina 10.15.7 ISO, you can run Apple’s classic operating system anywhere—from a Windows PC running VirtualBox to a 2009 Mac Pro breathing new life.
Verify app compatibility through your system report panel or upgrade your tools to 64-bit alternatives before proceeding.
A2: Yes, but not directly. You first install virtualization software (like VMware Workstation Player or VirtualBox) on Windows. Then, you use the .iso file to install macOS inside that virtual machine.
Under Storage Settings, click the Empty optical drive icon, choose "Choose a disk file," and select your Catalina.iso .
