Sur Iso 2021 | Macos Big

Since macOS Big Sur is technically a older operating system (released in 2020, with the final 11.x update released in late 2021), a "review" of a macOS Big Sur ISO 2021 typically refers to evaluating its use for virtual machines (VMs) rather than a review of the OS itself.

Virtualization: Software like VMware Workstation, VirtualBox, and Proxmox prefer .iso format for CD/DVD emulation.
Cross-Platform Flashing: Creating a USB installer on Windows or Linux requires an ISO, not a DMG.
Compatibility: Legacy bootloaders (Clover/OpenCore for Hackintosh) sometimes favor ISO structures.

7. Final Verdict: macOS Big Sur ISO (2021) – Score: 2/5
