Notice: MEGA is not optimized to run on newer macOS computers with ARM-based M1 chips. Although MEGA has been run on these systems, performance is very poor. For users with macOS systems using M1 chips, the Windows or Linux version of MEGA can be run using virtualization or emulation software. Several options for doing so are available including Parallels, Crossover, and VMWareFusion.

IMPORTANT: This version of MEGA is for macOS 10.14 (Mohave) and earlier. See system requirements below.

System Requirements

This version of MEGA is developed for use on macOS systems. For using MEGA on other operating systems please go back to the main page and select the appropriate operating system.

IMPORTANT: MEGA7 (and earlier) for macOS is a 32-bit application. Because macOS has dropped support for 32-bit applications beginning in version 10.15 (Catalina), the macOS version of MEGA7 (and earlier) will only run on the following versions of macOS:

  • 10.14 (Mohave)
  • 10.13 (High Sierra)
  • 10.12 (Sierra)
  • 10.11 (El Capitan)
  • 10.10 (Yosemite)
  • 10.9 (Mavericks)
For macOS 10.15 (Catalina) and later, 64-bit MEGAX can be used. Alternatively, the Windows version of MEGA7 (and earlier) can be ran on macOS by using virtualization software such as VMWareFusion.
