Following macOS 10.6, Apple changed how the macOS operating system rounds file sizes. Mac uses Base-10 to count file sizes, while most other platforms—including Box—use Base-2. Thus, a 100,000-byte file on the Mac appears as 100 KB in Finder, but appears as 97.7 KB on Box. This discrepancy is purely due to the different rounding method used in the macOS, and does not affect actual file size or data integrity.
