Question 2

Which type of partition schemes does macOS support?

Answer 2

macOS supports three partition schemes:

a. GUID Partition Map (GPT)—This is the default partition scheme used by Mac computers.

b. Apple Partition Map (APM)—This is the default partition scheme used by previous PowerPC-based
Mac computers.

c. Master Boot Record (MBR)—This is the default partition scheme used by most non-Mac computers,
including Windows-compatible PCs. This partition scheme is commonly used by peripherals that
store to flash memory.

Question 3

Which major volume formats are supported by macOS High Sierra?

Answer 3

macOS High Sierra supports these major volume formats:

• APFS—Used for solid-state drive (SSD) or other all-flash storage device.
• Mac OS Extended—Used before macOS High Sierra. Also known as HFS Plus.
• FAT—A legacy volume format used by Windows PCs.
• ExFAT—Created specifically for large flash storage disks larger than 32 GB.

• NTFS—The Windows default native volume format. macOS can read but can’t write to or start up from
NTFS volumes.
