    Note: While 27-inch iMac 2015 and later models do support installation of macOS 12 Monterey, at this time Apple does not support installation of macOS 12 Monterey on a drive larger than 16TB. Drives larger than 16TB remain compatible in the previous OS version, macOS 11 Big Sur. Should this be resolved in the future, this note will be updated. (Last updated August 1st, 2022)
