Programmatically Extract Saved Wi-Fi Passwords In OS X
Previously, I covered how to Programmatically Obtain Recent Wi-Fi Networks On A Mac. But, here I’m gonna’ go a step further and look at how to extract the password for a network as well. The two are stored in different locations. The recent networks are in the /Library/Preferences/SystemConfiguration/com.apple.airport.preferences defaults domain. If you pull one of those, then you can use the security command to extract the password itself. security find-generic-password -ga "Krypted Home" The output is as follows, showing everything that is tracked about this network in the keychain. keychain: "/Library/Keychains/System.keychain" class: "genp" attributes: 0x00000007 <blob>="Krypted Home" 0x00000008 <blob>=<NULL> "acct"<blob>="Krypted Home" "cdat"<timedate>=0x32303135313230373135313731375A00 "20151207151717Z\000" "crtr"<uint32>=<NULL> "cusi"<sint32>=<NULL> "desc"<blob>="AirPort network password" "gena"<blob>=<NULL> "icmt"<blob>=<NULL> "invi"<sint32>=<NULL> "mdat"<timedate>=0x32303135313230373135313731375A00 "20151207151717Z\000"…

The Second Edition of our Enterprise Mac Administrators Guide Now Shipping
My 14th book, The second edition of the Mac Administrator’s Guide is now shipping. This was a big, big rewrite, given the fact that the first edition was before the App Store, Gatekeeper, and many, many other technologies. You can buy this book here! Also, huge congrats to Bill Smith, for publishing his first book, and most notably for doing so much amazing work on this book! Finally, we’re editing the second and third books I did this past summer right now, so look out for those announcements shortly!

Use The jamfHelper Binary To Display Messages In OS X
The jamfHelper binary is used to deploy an alert to client computers that are enrolled in the JSS. This can be a full screen alert with headings, icons, text, and countdowns. This could also just be a small utility window that informs a user that something was installed. You can do similar tasks with push notifications, but I find that a lot of times an APNs update will disappear before someone can click on it. Therefore, we can use the jamfHelper binary to send alert screens in OS X. We’ll go through a couple of minor examples here. The first is to send a window called KRYPTED that is full screen, with test as the…

Is Imaging Dead In OS X?
I love answering a question with a question. Is asr still in OS X? Is NetInstall still in OS X Server? Can OS X still NetBoot? Does System Image Utility still work? The answer to all of these is yes. Therefore, the answer to “Is imaging dead” is clearly no. Is it on its way out, maybe. Debatable. Is it changing? Of course. When does Apple not evolve? What have we seen recently? Well, the rhetoric would point to the fact that imaging is dying. That seems clear. And this is slowly coming out of people at Apple. The word imaging is becoming a bad thing. But, as a customer…

No git Commit Message #tomhardy
Click for lightning. Merge-your-damn-self. But if you commit with a well written message (and not just a period to get past a sanity check), I’m happy. Tom Hardy likes it when you tell me wtf. via GIPHY

Repair Permissions Using The Command Line In El Capitan
Repair permissions was unceremoniously removed from OS X in El Capitan. This staple of the Mac gurus toolkit disappeared. There was no 21 gun salute, there was no flaming casket sent out to sea and there was no sweet, sweet wake to get drunk at. Instead, there was pain. There was pain, because when the button disappeared, the need did not. Need proof? If you haven’t yet run it, let’s check your system to verify the permissions of the standard packages: sudo /usr/libexec/repair_packages --verify --standard-pkgs --volume / In the above command, we used the repair_packages binary, which has not changed in awhile. We then feed that the –verify option and the…

Recruiting Good Mac Talent
When I was doing a lot of hiring, the pool of Mac Admins was smaller. And it was in a way easier for me to recruit people, because I knew a lot of them. As the pool has grown and a lot of the talent has matured, keeping your finger on the pulse of the hiring market around Apple has become much more challenging. Also, I’ve recruited far more developers and marketing professionals than Apple engineers in the past couple of years. But, there are still a number of places that you can look to find good Mac and iOS engineers looking for a gig. Here’s a quick and dirty…

My 3,000th Post On Krypted
This is my 3,000th post on Krypted.com. The past 3,000 posts have primarily been about OS X Server, Mac automation, Mac deployment, scripting, iOS deployments, troubleshooting, Xsan, Windows Servers, Exchange Server, Powershell, security, and other technical things that I have done in my career. I started the site in response to a request from my first publisher. But it took on a mind of its own. And I’m happy with the way it’s turned out. My life has changed a lot over these past 11 years. I got married and then I got divorced. I now have a wonderful daughter. I became a partner and the Chief Technology Officer of 318 and helped to shape it into…
