macOS Internals

Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.

You've got two main options:

	from time import time
	import sys

	def mksize (bytes):
	suffixes = ("B", "kB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB")
	suffixesLen = len(suffixes)

	for i in range(suffixesLen):
	if bytes < pow(1000, i + 1) or i + 1 == suffixesLen:
	return "%.2f %s" % (float(bytes) / pow(1024, i), suffixes[i])
