Problem
diskutil info /reports incorrect free disk space on Macs with localTime Machine snapshots or iCloud cache, because it ignores purgeable space.
Additionally, the binary divisor
1,073,741,824(GiB) does not matchmacOS/Finder display conventions which use
1,000,000,000(GB decimal).Example on affected Mac

Replace
diskutil info /withNSURLVolumeAvailableCapacityForImportantUsageKeyvia JXA (JavaScript for Automation), which matches the Finder calculation exactly.

1,000,000,000to align with macOS display conventions.Tested on
