Users are primarily faced with two major choices: Apple’s MacBooks or Microsoft’s Windows.

Perhaps you own a lot of Apple goods and have grown acclimated to the “eco-system,” or perhaps a simple Windows experience is all you need.
Even if the machine has some high-end specifications, no matter which operating system you choose, you are certain to run into problems at some point. Similarly, when it comes to the user experience, macOS is far from ideal. There are just too many limitations and concerns with which people must contend.
