iPhone Productivity In the Age of Work From Home

If you’re working from home, either because you always do or because right now it’s something you have to do, there’s a huge variety of ways you can use your iPhone to help you get that work done better.

And, to help me get this video done better, I asked some of the smartest, most productive people I know to share their pro tips.


iPhone SE vs. iPhone 12 — New podcast w/ Brian Tong

When I asked you all for iPhone SE questions you wanted answered, I got pretty much what I expected. Size. Camera. Battery. The usual stuff. But, I got one questions, repeatedly, that I wasn’t expecting:

Should you get the iPhone SE now or wait for the presumed iPhone 12 late this year?

See, to me, one is a $399 entry-level iPhone with a classic, iPhone 8-style Home button, iPhone 11 chipset, and camera somewhere in between. The other will likely be a $699+ premium iPhone with a modern design and the latest, greatest chipset and camera on the market.

They’re just so different. But, people just don’t see it that way. Or, maybe, don’t care. Some people just want a new iPhone this year and it’s not just about the price but about the value — the best set of features for them for the price.

So, I asked Brian Tong of YouTube fame to talk it through with me while he was on my new podcast. Oh, yeah, you know I had to start a new podcast.

I meant to wait a few months more but then all this happened, so… here we are.

The audio version will be in your favorite podcast app soon or, if you have Nebula or have joined the early access tier of my Patreon — yeah, I’ve got Patreon as well, I’m indie now, remember? — you can head on over and watch the entire 40 minute conversation right now.

That's where Brian and I talk about going indie, how to make a living on YouTube, what happened on iPhone SE day, and, tangent, both of our abiding love for comic books

If you sign up for Patreon, you not only get to see the full video version of the podcast right now, you get to see scripts for most of the daily shows before they’re even shot, as well as Discord, where we chat about Apple, gear, workflows, and more, and there are even ways to get you name in description of every video, or the credits.

(And, of course, you’ll get early access to future episodes of Season 1 of the podcast as well.)


iPhone SE vs. iPhone XR vs. iPhone 11

Apple’s got a brand new iPhone SE and it starts at just $399. That’s way less than any of the current flagships, including the iPhone 11 at $699, and even the previous generation iPhone XR at $599.

But, as anyone who watches this channel knows, price isn’t the same as value. So, if you really do need to buy a new iPhone right now, now, now, which new iPhone will be the best value for YOU?

Latest macOS beta previews new MacBook charging manager

The latest macOS developer beta has a new feature to better manage the charge level of recent MacBooks (ones with T3 ports) in order to better preserve battery health.

Basically, if you're plugged in and doing something that generates a lot of heat, like rendering content, it'll ramp down charging to preserve battery health.

The feature will roll out to the public beta soon and to everyone when macOS 15.5.5 ships.

🔌 If you stay plugged in to render a ton of content, leave it on.

🔋 If you’re going on a long plane ride, turn it off

Jason Snell has a good write-up on it, of course:


The New $399 iPhone SE is Here!

The new iPhone SE is here. That’s right. Not iPhone 9. Just iPhone SE, the second generation. Just the iPhone SE, new and improved for 2020.

It’s replacing the iPhone 8 in Apple’s lineup, though not completely the iPhone 8 Plus yet.

And I’m not just going to tell you what it is. I’m going to tell you why it is and, most importantly, who it’s for. Even and especially if that’s not you or… even me.

AirTags: Apple’s Next Little Thing

New iPhones are cool. The new entry-level iPhone is cool, the upcoming iPhone 12. Cool. But sometimes it’s what comes with new iPhones that ends up being really cool. Like the iPhone 7 and AirPods.

And… I think it’s about to happen again. With AirTags.

If you’re not familiar with the term, AirTags are the long-rumored little thin-mint shaped accessories from Apple that’ll give pretty much anything you own Find my iPhone-like capabilities. Maybe better.

Now, Apple hasn’t announced AirTags yet, not at the September 2019 iPhone 11 event that was… or at any March 2020 iPhone event that wasn’t.


Apple has been slow jamming all the set up work for them for over a year already, starting with the new Find My network last June at WWDC 2019 and a deeper dive at BlackHat 2020.

Now, as you know, I’m never as interested in the what and when as I am the how and why.

So, let’s start with the how, or the highly differentiated user experience in Apple parlance.

I figure it’s going to go something like this:

You unbox your AirTags and immediately pair them with your iPhone or iPad. On the outside, it’s super slick and easy, just like AirPods. Tap to connect and done.

On the inside, though, something really clever happens. And it’s all about privacy and security.

The set up creates an elliptic curve P-224 private key pair as well as a symmetric key and stores both in your iCloud Keychain, Apple’s built-in security system, and then syncs it to all your other Apple devices over secure CloudKit. The same way health data and other sensitive information gets synced.

Then, let’s say you put an AirTag in your house keys and…

…promptly lose your house keys.

Maybe on your next trip to the supermarket because that’s pretty much the only place many of us can go right now.

OK, so, what AirTags do, their literal one job, is to broadcast a Bluetooth Low Energy beacon. Think of it as an uterly silent ping… ping… ping. That just says “I am here.”

Now, the beacon is based on your symmetric key which, because of P-224, is 28 bites, and fits just ever so nicely inside the 32-bite packet limit for Bluetooth 5.0.

Because it’s Bluetooth, it doesn’t matter if that the AirTag isn’t on Wi-Fi or a cellular network. It’s doesn’t need to get on the world wide internet. It’s just raising its electromagnetic hand locally. Hyper locally. Within Bluetooth range.

Because it’s Low Energy, it’s also going to have minimal impact on battery life. Which is good. Because a dead AirTag would be much harder to find.

And, because the beacon is only BASED on your static symmetric key, even though it’s pinging away like the Red October over there, it makes it hard for anyone to use those pings to try and track you over time and space.

See, what it does is take your symmetric key and, every 15 minutes, uses it to generate a second key that’s based on your original key and that time interval. Then, it derives a third, public key and uses that to unlinkably diversify the actual data in the ping it’s so busy broadcasting out.

To ridiculously over simplify it, it’s like taking the letters of your name, adding all the letters that spell out the time, shaking them all together, then wrapping them up in a new rando lock-box every 15 minutes, and throwing the box into a lake filled with other boxes that are also changing, seemingly at random, every 15 minutes.

You know your name and you have the key to the box, but good luck to anyone else trying to break in and figure it all out.

What this means is, shopping malls can’t the AirTags ping to log you as you go from store to store, not for longer than 15 minutes, and no one can use it to track your location for any longer than that either. Not in any place where there’s any density of Bluetooth activity.

Now, if someone else with an Apple device comes within Bluetooth range of the AirTag attached to your house keys, and they’ve also opted-in to the Find My network, they become what’s called a finder. And no, that doesn’t make the rest of us losers. Except for that yeah, we lost our wallet. But whatever.

Here’s what happens next:

The finder’s device, let’s say it’s an iPhone, will pick up the public key being broadcast by your AirTag and use it to ECIES the finder’s location. That data is then hashed into a lookup index using SHA256 and relayed to Apple.

So, Apple ends up having your public key and the location where it was broadcast stored for that lookup table.

Now, your identity remains private because the public key doesn’t contain anything about it. It’s just a pseudo-random blob of data. So, the finder has no way of knowing who you are just because they came within range of your AirTag or house keys.

And because this is all happening behind the scenes, the finder doesn’t even know they’re relaying any information to Apple or maybe even that your house keys are there. Not unless they stumble on them completely separately from the Find My system.

Second, if you’re the finder, you don’t have to worry about your privacy either. The location data comes from your iPhone using typical location services — Wi-Fi router mapping, cellular triangulation, assisted GPS, but nothing aside from the location is sent. Nothing that says you’re the one at that location. You could literally be anyone.

Also, because Bluetooth LE, and things like network coalescence, which basically just means Find My waits to relay until the processor and modem are waking up anyway, like to check for messages, there’s very little impact on the finder’s battery life either. Even if it’s constantly, passively, picking up pings. Just like it would be from AirPods, Apple Watch, AirDrop, or other accessories or features anyway.

And, the Find My network is opt-in. No one has to be a finder and relay AirTags if they don’t want to. Though the more literally the better for everyone.

The relay is encrypted from the finder’s device to Apple, so even if somebody bothered to try and eavesdrop on it, all they’d get is that pseudo-random blob. And, since Apple doesn’t have your private key, only your devices do, Apple can’t tell what’s in the blob either. Not that it’s for your device, not what time, and not where. All Apple can do is store the report or reports as they come in.

Ok, so, how do you get your house keys back?

Well, once you realize they’re missing, you turn on your iPhone, hit the Find My app, and tap on the AirTag that’s attached to them.

Then, your iPhone will first pull that AirTag’s information from iCloud Keychain and start going back and computing all the 15-minute interval public keys and lookup indexes its generated, and ask Apple’s servers for any matching reports.

If there are any, Apple will send them down, again as encrypted blobs between their servers and your iPhone so no one can listen in, and then your iPhone will ECIES decrypt them and show you where your AirTag has been, and when.

In other words, your house keys will just show up in Find My the way your iPhone or iPad or other Apple kit has for years now and, hopefully, you’ll simply be able to go out and pick them up. No frantic calls to families or locksmiths, not with all this going on as well.

Right now, today, you can use Find My to ping any device with a speaker — yes, fine, one ping only — so you can try to find them even if you can’t immediately see them.

But, accessibility not only demands options but really is for everyone. So, soon, I imagine that soon you might be able to use things like the U1 spatial positioning chip in the iPhone 11 to laser pointer the location of your lost device, or the LiDAR scanner on the new iPad Pro to augment the reality of the world transparent around you and make your lost items glow. Like neon.

That’s the how. The way, in this case, I think is easy: AirTags, like AirPods, will further add to the value of owning an iPhone, and the network value of owning multiple Apple products. Yeah, the ecosystem play.

For Apple, they spent a decade building up the iPhone and iCloud as a platform so they can now use that platform to build up the next decade of products… and more recently, services. AirTags+?

For us, we get convenience and features greater than the some of any individual part.

But, there will be a few question, even controversies Apple will have to address.

First, some people are going to worry that AirTags will be abused by bad actors. That someone could just drop one into your gym bag and use it to track you.

That’s something Apple should get ahead of right away, during the introduction, however it’s done.

Sure, people can do that already with similar, existing products like Tile. And never mind every action show on TV has had a plot or several showing exactly that being done with a cell phone. That won’t stop it being made all about Apple, because nothing makes a product or headline as mainstream as making it all about Apple.

Second, some people are going to accuse AirTags of stepping all over Tile, because Tile is similar and already exists. Just like there were headphones before AirPods and prior versions of pretty much everything Apple’s ever made.

Apple’s advantage will be integration with Apple devices in a way that’s not only unmatched by third parties but unmatchable. Tile’s will be the ability to do everything Apple typically refuses to do, like offer a lot of options, including cross-platform support for Android.

AirPods are super popular now, to be sure but, in part thanks to them, we now have very similar headsets and much better competition from a wide range of companies.

Apple could, and I’d argue should, offer APIs, application programming interfaces, for third parties to make all this stuff better for everybody. Sure, Sony or Tile wouldn’t be able to do anything like the custom silicon Apple will be pouring into their own accessories, but Apple should want any experience to always be better on Apple devices.


MacBook Air (2020) Review: One Month Later

The new MacBook Air, an update to the 2018 redesign, got pretty good reviews when it came out a month ago. People liked the new keyboard, the new chipsets, and the lower price. But, there were a few criticisms as well. Basically, the still low-res webcam, some concerns about thermal throttling on the faster CPUs, and the battery life.

Since then, I've had time to pound on the Magic keys, compare the webcam to pretty much everything else I have, really dig into the thermals, and there's even been a macOS Catalina supplemental update.

So, what's the verdict? Read the whole thing in my weekly column over at iMore.
