Microsoft implemented this feature to counter piracy issues in Windows, while Mac has been using UEFI for quite some time now.

Why is UEFI better than Legacy BIOS?

UEFI provides faster boot time. It is slower compared to UEFI. Since UEFI uses the GPT partitioning scheme, it can support up to 9 zettabytes of storage devices. The MBR portioning scheme used by Legacy only supports up to 2 TB storage devices.

Is UEFI the same as BIOS?

UEFI is an improvement or evolution of the BIOS. Its functions are basically the same, to which it adds greater security, speed and compatibility with modern devices. In addition, UEFI is capable of supporting hard drives that exceed 2.2 Tb, which is a limitation for the BIOS, since it cannot boot them.

What is the purpose of UEFI?

Both BIOS and UEFI are forms of software that kickstart the hardware of your computer before your operating system loads. UEFI is an update to traditional BIOS that supports larger hard drives, quicker boot times, more security features, and more graphics and mouse cursor options.

Does UEFI has better compatibility with newer hardware?
