Disadvantages of macOS

• Limited Software Availability

macOS is excellent for creative and productivity apps. But some specialized software are only available on Windows OS. This limits users who rely on engineering/design programs exclusive to Windows.

• Cost

Macs are more expensive compared to many Windows-based systems. This is primarily due to the premium hardware and high-quality macOS. However, the higher price point can be a drawback for budget-conscious users.

• Compatibility Issues

macOS does a lot to ensure integration with the Apple ecosystem. But if you need software designed for Windows, compatibility is a challenge. Workarounds like Boot Camp or virtual machines exist, but it’s an extra hassle.

• Gaming Limitations

macOS has access to a growing library of games. But the selection still pales in comparison to Windows. Also, Mac hardware isn’t optimised for gaming, making it a less ideal platform for gamers.

• Limited potential of macOS Recovery

Despite its robust security and optimization, data loss can still occur on macOS. It could be due to accidental deletion to drive failure or corruption. While macOS Recovery does help fix basic macOS issues and can be used to restore data using the Time Machine backup, it often doesn’t suffice. For example, if you don’t have a backup or accidentally empty the Trash, you don’t get any option for data recovery.
