<human>:  What is the difference between a mac and a PC?
<bot>: The main difference between a Mac and a PC is that Macs are powered by Apple’s operating system, macOS, while PCs are usually powered by Microsoft Windows or Linux. Macs typically use Apple-designed hardware components, whereas PCs may use hardware components from multiple companies. PCs also tend to have more customization options than Macs, allowing you to more easily change the internal components such as processors and graphics cards. Additionally, Macs are priced higher, with limited configurability, while PCs may cost less and have more flexibility in terms of hardware.
