I've just downloaded OS X Mavericks on a Mac.

I'm trying to convert the file:

/Applications/Install\ OS\ X\ Mavericks.app\Contents\SharedSupport\InstallESD.dmg

contained inside the download to a .cdr (AKA .iso AKA ISO 9660) file.

I've tried a couple of conversion programs but both of them report that the file is corrupt.

Hence, I would like someone to post the MD5 checksum so that I may check the file's integrity with the md5 command from the Mac shell?

That is the only way to determine whether this file is intact or not and if someone could post the MD5 sum I would really appreciate it.

For OS X Mavericks 10.9.0 (build 13A603):

  • MD5: f222952400db8535c03697c3293e168e
  • SHA1: e804dea01e38f8cd28d6c1b1697487e50898dbe7

    I would caution people. There are several builds of Mavericks and Apple doesn't guarantee that different hardware won't download a different InstallESD.dmg based on what build is required for a certain point release and hardware that's available. – bmike Nov 16 '13 at 18:42
  • Isn't there an official disk image with its md5 and sha1 checksums on the Apple web server? – dan Nov 16 '13 at 19:23
  • @danielAzuelos what's served by Apple is not a disk image; it's more than the .dmg alone. – Graham Perrin Nov 17 '13 at 8:21
  • Yes, OS X Mavericks, like other versions of OS X, is only available from the App Store. However InstallESD.dmg is the bulk of the download. The whole OS is downloaded to /Applications/Install\ OS\ X\ Mavericks.app . As of today 17 October 2013 this file corresponded to the posted MD5 checksum on my system. Thanks. – John Sonderson Nov 17 '13 at 21:29
