Q: SHA1 fingerprint does not match

Mine says valid at the top, but the SHA1 fingerprint does not match the two given in the article HT202369. Mine shows 1E 34 E3 91 C6 44 37 DD 24 BE 57 B1 66 7B 2F DA 09 76 E1 FD.

MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10.4)

    All of that stuff is checked automatically on OS X. Where are you downloading OS X updates from?

    While the update software does automatic checking, the SHA1 fingerprints should still match what is in the article.  I find, as you do, that they do not match:

     

    The SHA-1 fingerprints for both  osxupd10.10.5.dmg and itunes12.3.2.dmg do not have on of the fingerprints shown in this article, but rather:  1E 34 E3 91 C6 44 37 DD 24 BE 57 B1 66 7B 2F DA 09 76 E1 FD .  Is the article mistaken? or the download invalid?  According to the article, we should not use these files.
