Because it was based on Ubuntu, GMac provided a stable and reliable foundation with access to vast software repositories, including the "GMAC Store" (a themed Ubuntu Software Center). The Legacy of PearOS and GMac
The original developer project pages on SourceForge have removed the core release files. However, the file is actively mirrored for archival research purposes:
Before resorting to a legacy ISO, consider these safer, more up-to-date methods:

Gmac (often referred to as Gmac Linux) aims to provide a seamless transition for Mac users moving to Linux by recreating the desktop experience of Apple’s operating system. The Gmac10-x64.iso file is the 64-bit installation image, typically based on an Ubuntu Long Term Support (LTS) release. Gmac10-x64.iso

The Gmac10-x64.iso file is a bootable "Live DVD" image of the operating system, which Rodrigo Marques uploaded to the SourceForge project hosting platform.
Because this ISO manipulates low-level hardware, improper handling can permanently damage your network interface. Follow this step-by-step guide.
The story of Gmac10-x64.iso is one of a brilliant but brief spark. In May 2016, just one month after the rebranding, developer Rodrigo Marques released what would be the final stable version, Gmac 10.3. Shortly after, the project was abandoned. The project files were eventually removed from SourceForge, though community archives remain on sites like GitHub. The most plausible reason for its sudden end is the immense time and effort required to maintain a complete Linux distribution, especially one built on extensive custom theming, which is a common challenge in the open-source world.
While you wouldn't use Gmac10 as a secure, daily-driver workstation in 2026—given that its security patches are many years old—the Gmac10-x64.iso is still valuable for: Elara Vance was a digital archaeologist, and her
: Features an exceptionally beautiful, fluid desktop layout containing an integrated dock, global blurring effects, and a highly polished system control center.
Gmac10-x64.iso almost certainly lacks a valid Secure Boot signature. You must disable Secure Boot in your BIOS/UEFI settings, or boot in Legacy/CSM mode.
You can create a bootable USB drive using tools like (on Windows) to write the ISO to a USB stick. This will allow you to either run the "Live" environment for a test drive or install the system permanently.
