The codesign command is used to sign apps and check the signature of apps. Apps need to be signed more and more and more these days. So, you might need to loop through your apps and verify that they’re signed. You might also choose to stop trusting given signing authorities if one is compromised. To check signing authorities, you can use
codesign -dv --verbose=4 /Applications/Firefox.app/ 2>&1 | sed -n '/Authority/p'
The options in the above command:
Then we pipe the output into a simple sed and get the signing chain. Or don’t. For example, if you’re scripting don’t forget a sanity check for whether an object isn’t signed. For example, if we just run the following for a non-signed app:
codesign -dv --verbose=4 /Applications/Utilities/XQuartz.app/
The output would be as follows:
/Applications/Utilities/XQuartz.app/: code object is not signed at all

Last night, I went to setup a new Nest Protect in my home, and while I was futzing with the app (yes, futzing is the technical term) I missed the question that was asked on the device about what language to use while waiting at this screen.
And so my Nest Protect was speaking Spanish. Which is fine with me; but notsofine for my daughter. So, I needed to change the language. And after hunting for the setting for awhile, I thought: self, you should document this.
So to change the language on a Nest protect, open the Nest app and then tap on the icon for Protect (which will appear once you’ve associated the first Nest Protect to your account. Then tap on the Settings gear icon in the upper right corner of the screen, which allows you to configure all your Nest Protects at once. Then tap on the Protect you want to change the language on and there’s a magical setting for Spoken Language there. Tap that and select the language you wish to use. Out of the box, the device only supports English and Spanish. But once setup, you can change the language to French or Dutch. So this is also the method to unlock French and Dutch language support on the device.
Once changed, you can replicate the change to other devices by cycling through them. I also noticed the setting didn’t appear on my iPhone. I had to use an Android device to access my Protect and make the change. The setting doesn’t seem to be a part of the iOS code. But YMMV.

Who still says “like a boss?” I guess I did. Get over it. But don’t get over spam. Especially annoying are the ones we know we accidentally signed up for. Because it’s our own darn fault. But luckily, there’s a lot more tools for dealing with bulk mail (solicited or unsolicited) these days. Most modern email clients have the ability to deal with spam. Exchange/Office 365 has clutter and junk. You can build rules on sites. You can use spam assassin on your servers. But, there’s also a nice little app called unroll.me. Once you sign up you’ll have 3 ways of dealing with each message: request removal from a list, mark as rolled up into a single daily digest, or mark as good email.
Download it here. The app works a lot like something like Tinder. You swipe right to like something, left to not like something. Facebook should implement this into your timeline!
If you decide to mark emails as digests, you’ll get an email once a day that looks like this:
This works great for organizations that actually properly remove you from lists (which is surprisingly most). Using this swiping type of workflow, you can knock through 100 or more emails in 10-15 minutes. For organizations that don’t respect unfollow or stop sending me your crap emails, there’s also always just marking them as spam. The only problem with this is that you likely have a phone, a computer, a home computer, and maybe a tablet. No one wants to mark the same email as spam four times and then potentially have emails disappearing and not being able to figure out which computer they were marked as junk on.
There are lots and lots of options for this type of thing. But given the ease of use an quick evisceration I can do on my mailbox, I rather like unfollow.me. Give it a shot. You might hate it. I don’t.

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 what was the largest provider of Apple services, I left Los Angeles and moved to Minnesota, left 318 to help start up a new MDM for small businesses at JAMF Software called Bushel, and now I have become the Consulting Engineering Manager at JAMF. In these 11 years, I have made a lot of friends along the way. Friends who helped me so much. I have written 14 more books, spoken at over a hundred conferences, watched the Apple community flourish, and watched the emergence of the Post-PC era.
In these 11 years, a lot has happened. Twitter and Facebook have emerged. Microsoft has hit hard times. Apple has risen like a phoenix from those dark ashes. Unix has proved a constant. Open Source has come into the Mac world. The Linux gurus are still waiting for Linux on the desktop to take over the world. Apps. iOS. iPad. Mobility. Android. Wearables. Less certifications. More admins. And you can see these trends in the traffic for the site. For example, the top post I’ve ever written is now a list of Fitbit badges. The second top post is a list of crosh commands. My list of my favorite hacking movies is the third top post. None of these have to do with scripting, Apple, or any of the articles that I’ve spent the most time writing.
That’s the first 3,000 posts. What’s next? 3,000 more posts? Documenting the unfolding of the Post-PC era? Documenting the rise and fall of more technologies? I will keep writing, that’s for sure. I will continue doing everything I can to help build out the Apple community. And I will enjoy it. I’ve learned a lot about writing along this path. But I have a lot more to learn.
The past 3,000 posts have mostly been technical in nature. I’ve shown few of my opinions, choosing to keep things how-to oriented and very technical. Sure, there’s the occasional movie trailer when I have a “squee” moment. But pretty technical, overall. I’ve been lucky to have been honored to speak at many conferences around the world. One thing I’ve noticed over the past few years is that when people ask me to speak at conferences, they ask me to speak about broader topics. They don’t want me doing a technical deep dive. People use the term thought leader. And while I don’t necessarily agree, maybe it’s time I step up and write more of those kinds of articles here and there.
I’ve learned so much from you these 11 years. But I feel like I’ve barely scratched the surface. I look forward to learning together over the course of the next 3,000 posts! Thank you for your support. Without it, I’d have probably stopped at 10 articles!

Now that I’ve found the right calculator for me, I should point out that I still take my phone out of my pocket to use a calculator. That’s a habit thing though, not a problem with the size of the objects on the Apple Watch.
Calculator for Apple Watch is a free, basic, standard little calculator app. It’s the app that could be built into the Apple Watch.
Calcbot is a slight step up from Calculator. Here, we gain the ability to convert some basic things as well, such as kilograms to pounds, Fahrenheit to Celsius and a few other little things. There’s also a little tip calculator for those who need it.
If you need more functions, you can also do some scientific functions, fractions, percents, etc with this one.
Oh, and Calculator+ supporting using handwriting!
Similar to Calculator+ but adds constants and conversions. See the ellipse. That opens up a lot of different options. And you have a glance to see recent calculations from the iOS app, which can be cool if you’re in a meeting!
Scientific calculator (the only one where the numbers are separate on the screen). Also has history and the options available in PCalc, but adds speakable items!
Simple currency converter. A few of the more traditional calculator apps have some currencies, but XE has all the world currencies.
As with a few of the calculator apps, this one has themes, so you can match it up with your band. But it also has a tip calculator, basic conversions and some of the bigger buttons (’cause lets face it, it’s a small screen).
All the calculator things, matched to your watch band – but you have to buy it.
Very basic calculator but with big buttons. Buttons are big because there are multiple objects within them. If you need bigger buttons give this one a shot.
Another specialty calculator. How much is $20 from 1980 worth today?
Bonus: There are tons of calorie counters out there for both Apple Watch and iPhone.
Bonus 2: There are tons of tip calculators out there for the Apple Watch, but I didn’t include any of those here.

There are certain instances where an app that has push capabilities stops leveraging Apple’s Push Notification Services (APNS). This can happen for a few different reasons. But there’s no error correcting for this process and so occasionally, you’ll want to reset the app back to what amounts to a factory default status, in order to get Push working again. The first time an app is opened, it will register for push notifications and prompt for receiving push notifications for the app. This prompt never occurs again unless the app is uninstalled for a minimum of a day and then reinstalled. You can duplicate this functionality by simply deleting the app and then installing the app again after setting the Date & Time manually a day ahead of the current date.
