VirtualBox is a popular open-source virtualization software developed by Oracle. It allows users to run multiple operating systems on a single machine, making it a valuable tool for developers, IT professionals, and anyone who needs to work with different environments. However, many Mac users wonder whether VirtualBox is compatible with macOS and how well it performs on Apple hardware.
VirtualBox Compatibility with macOS
VirtualBox does work on macOS, but with some caveats. The software is available as a macOS application and can be installed on Intel-based Mac computers without significant issues. However, with the introduction of Apple’s M1 and M2 silicon chips, compatibility has become more complex.
Support for Intel-Based Macs
For Macs equipped with Intel processors, VirtualBox runs reliably and supports a wide range of guest operating systems, including Windows, Linux, and even macOS itself (with some limitations). The installation process is straightforward:
- Download the macOS version of VirtualBox from the official Oracle website.
- Install the package by following the on-screen instructions.
- Allow necessary security permissions in macOS System Preferences.
- Set up virtual machines as needed.
Intel-based Macs offer full VirtualBox support without the need for special workarounds.
Challenges with Apple Silicon (M1 & M2)
Apple transitioned from Intel processors to its custom M1 and M2 silicon starting in 2020. This shift has created challenges for software that relies on x86 architecture, as Apple’s ARM-based chips are incompatible with traditional x86 virtualization. As a result:
- VirtualBox does not natively support Apple Silicon.
- Running x86 operating systems in VirtualBox on an M1 or M2 Mac is not feasible.
- Alternatives like UTM (which is based on QEMU) or Parallels Desktop are more suitable for M1/M2 Macs.
While VirtualBox may eventually release an ARM-compatible version, as of now, it is not a viable solution for Mac users with Apple Silicon.
Performance Considerations
When running VirtualBox on a Mac, users should consider system performance. Virtualization requires significant processing power and memory, and performance depends on the hardware configuration:
CPU & RAM
Virtual machines require a portion of the host system’s resources. To ensure smooth performance:
- Use at least a quad-core Intel processor for optimal performance.
- Allocate sufficient RAM (at least 4GB for Windows or Linux VMs).
Disk Space
Virtual machine files can be large, especially with multiple OS installations. A fast SSD and at least 50GB of available storage are recommended for an efficient experience.

Alternatives for Mac Users
For Mac users who cannot use VirtualBox effectively, there are several alternatives:
- Parallels Desktop: A paid virtualization tool optimized for macOS, with full Apple Silicon support.
- VMware Fusion: Offers good performance on Intel Macs and is working on Apple Silicon support.
- UTM: Uses QEMU for virtualization and emulation, making it an option for running x86 operating systems on M1 and M2 Macs.
Conclusion
VirtualBox is a functional and reliable choice for virtualization on Intel-based Macs. However, it is not currently compatible with Apple Silicon, which limits its usability for newer Mac models. If you have an Intel Mac, VirtualBox remains a cost-effective and capable solution for running multiple operating systems. For M1 and M2 Mac users, exploring alternative virtualization software is necessary.
