How to migrate from your old Mac to a 12-inch MacBook

Apple’s 12-inch MacBook is svelte and weights only 2 pounds. It also presents some challenges when migrating your data directly from another Mac.

All other Mac models since 2011 have Thunderbolt capability, meaning you can attach a Thunderbolt cable between the two computers, put the older computer into Target Disk Mode, and then use Migration Assistant on the new computer, which will see the old computer’s drive and copy from it.

The 12-inch MacBook has the same USB-C port found on current MacBook Pros and iMacs, but unlike those models, the port doesn’t offer Thunderbolt, so the method I just described doesn’t work. But there are still a couple of ways to do it. Make sure your 12-inch MacBook is fully charged before you start, since it won’t have wall power during the transfer.


Short version:

Via a hard drive: You can use migration assistant with a Time Machine USB external drive (or Time Capsule) as a source. You could also use Carbon Copy Cloner on your old Mac to copy its contents to a a USB external drive, and use that as a source for Migration Assistant.

Computer-to-computer: If you get a USB-C to male USB-A cable, and the old Mac is a 2012 model or later (meaning it has USB 3.0), you can go the other way. Erase the 12-inch MacBook’s drive; in that article, see the section “If you need to erase your startup disk,” about halfway down, and, for format, select APFS if the old Mac has High Sierra or later, or Mac OS Extended (Journaled) if not. Then put the new MacBook into Target Disk Mode, and use Carbon Copy Cloner on the old Mac to copy its entire drive, including the operating system, to the new MacBook. If the old Mac doesn’t have a current enough operating system to boot the new MacBook, you can start the 12-inch MacBook via Internet Recovery (command-option-R during startup), and reinstall macOS, which will upgrade the copied operating system. In the end, you’ll have gone computer-to-computer, despite the 12-inch MacBook not offering Thunderbolt connections.


Long, step-by-step version:

In any of the scenarios below, you’re going to want your new 12-inch MacBook to be fully charged, because you can’t have it plugged into the wall while you’re transferring. I’m also assuming the new MacBook has a drive that’s large enough to hold everything that was on your old Mac.

One option is to use an external drive that has a copy of your computer. If you have existing Time Machine backup on a hard drive, make the backup current by choosing “Back Up Now” from the Time Machine (backwards clock icon) menu at the top of your screen, eject the drive when it’s done, and then attach it to the new MacBook, using a USB-C to USB-A adapter. Or, if you have a Time Capsule, that’ll work too; just follow the same process to make it current (but don’t disconnect it) Either way, Migration Assistant will present your backup as a source to migrate from; if you’re doing Time Capsule over Wi-Fi, be prepared for it to take long time.

If you don’t have a Time Machine backup, or you don’t want to wait for a Time Capsule, you can get a hard drive and copy your whole computer using Time Machine or Carbon Copy Cloner (or, for much faster speed, use an external solid state drive like the Samsung T5).

But there’s also a way to go computer-to-computer, provided the original Mac is a 2012 model or later, meaning it has USB 3.0 ports. The general concept is that, rather than use Migration Assistant, you’re going to erase the new Mac’s drive, and copy the entirety of your old Mac, by using the 12-inch MacBook’s USB Disk Mode. You’ll end up with a clone, with the same operating system as the old Mac, on the new MacBook, and then you can upgrade it to the current operating system if you wish to, or if it’s necessary. Here’s the process:

  • You’re going to need a USB 3.0 or 3.1 USB-C to USB-A cable. Unlike the adapters Apple sells that have a female USB-A connector, this cable needs to have a male USB-A connector on one end.
  • Check the operating system on your older Mac by choosing About This Mac from the Apple menu. Then check the minimum operating system required on the MacBook, by visiting Ideally, the original computer has an operating system that is newer than the minimum. (So, for example, current MacBooks have a minimum operating system of 10.12.5, which means that your original computer should be on 10.12.6.)
  • If your Mac has an older operating system that won’t run on the MacBook, that’s OK, but when you copy over your system, you’ll need to immediately reinstall its operating system before you can use the 12-inch MacBook, as I’ll explain. Alternatively, you can update or upgrade the operating system on your old computer before you copy, but, as always, make sure you have a backup first.
  • Start up the 12-inch MacBook in internet recovery mode by holding down command-option-R immediately after you press the power button. If you don’t see a spinning globe, restart the computer, holding down the keys. If it takes, you’ll see the globe, and after a little while be asked to choose your Wi-Fi network. Do that, and then wait for the Recovery Disk to load. (We’re about to erase the internal drive, and I’ve had better luck using a High Sierra recovery disk to properly erase a disk that has the APFS file system on it.)
  • Once it loads and you get to the Recovery menu, open Disk Utility. Go to the View menu at the top of the screen and choose “Show All Devices”.
  • Click on the Apple SSD in the upper left of the window. On the right side, click the Erase button. Name it “Macintosh HD” if you feel like being traditional, or anything else you like.
  • Make sure Partition Scheme is “GUID Partition Map”.
  • For Format, If your old Mac has High Sierra on it, choose “APFS”. If the old Mac has Sierra or earlier, choose “Mac OS Extended (Journaled)”.
  • Click Erase. If you get an error, which is entirely possible due to bugs in Apple’s Disk Utility, just click the Erase button again, until it works. If it continues to bug you, click on “Macintosh HD,” then click Unmount, then try again.
  • Quit Disk Utility. Restart the computer, holding down the T key this time. If it takes, you’ll immediately see a large USB (trident) logo on your screen, rather than an Apple or anything else. If you don’t see this, you may need to force off the computer by holding down the power button for ten seconds, and try again.
  • Connect the USB-C to USB-A cable between the two computers. You’ll see your newly erased drive appear as a drive on your old Mac.
  • Run Carbon Copy Cloner on your old Mac to copy your old drive to your new drive. If you are copying a system that is new enough to run on the new machine, then elect to create a Recovery Partition when it asks. If you’re copying a system that’s too old, then decline.

When it’s all done, eject the 12-inch MacBook’s drive from the desktop on your old Mac, and turn off the MacBook by holding down the power button, and disconnect the cable.

If your old Mac had an operating system that is new enough to run on the 12-inch MacBook, you can now just turn on the MacBook, exactly as you would have on your old Mac. and you’ll be in business. If you want to update or upgrade it to the latest and greatest, you can do so from the Mac App Store, as usual.

You’ll probably need to sign in to and/or reactivate various services and software, such as iCloud, Dropbox, Microsoft Office, and cloud backup like CrashPlan or BackBlaze.

Free iPhone Wallpaper Shows Inside of your iPhone

IFixit has just created free iPhone wallpaper that shows you the inside of your phone. Imagine how cool your phone will look, with a lock screen or home screen showing what’s under the glass.

This is for iPhone X, but scroll down to the bottom of the page for links to other iPhone models. Plus there are instructions on how to set it up on the phone.

If you’re curious to see iFixit’s teardown of the new iPhone X, it’s pretty cool too. And of course don’t forget if you want to do your own repairs on your iPhone or Mac, iFixit is the place to go.


Troubleshoot Netflix Streaming Problems

Whether you watch Netflix on your iPhone, iPad, Mac, or Apple TV, the quality of the video is determined by the speed of your Internet connection.

Netflix recommends 25 megabits per second (Mbps) of download speed for Ultra HD quality, 5 Mbps for HD, and 3 Mbps for SD – and 1.5 Mbps is the lowest recommended speed.

So how do you tell what your actual internet speed is right now? Visit Netflix’s Web site for a quick report on how much bandwidth you have. If what you see doesn’t match with what you think you’re paying for, call your Internet service provider and make sure your connection is working properly.

So What Is a Retina Display?

You’ve seen and heard Apple talking about the iMac with 5K Retina display, the MacBook Pro with Retina display, and so on. But what is a Retina display, and why should you care?

Retina displays are high-resolution screens on which graphics are extra sharp and text is super crisp.

The LCD screens used in Apple’s displays use a grid of “pixels”—the smallest possible dot whose color can be controlled—to create all the text and graphics you see. Today’s iPhone 7 Plus screen can fit 401 pixels into each inch. As pixel density goes up, the pixels get smaller. With a 72 ppi (pixels per inch) screen, it’s easy to see each individual pixel in a character, but the higher the pixel density, the harder it becomes to pick out separate pixels.

When Steve Jobs unveiled the iPhone 4 in 2010, he said that for a screen that’s held 10 to 12 inches from the eye—about the distance at which many people hold their iPhones— the human eye can’t resolve individual pixels if it’s about 300 ppi. At longer distances, it becomes harder to discern small details, so most people won’t be able to pick out pixels on a screen viewed at arm’s length, such as an iMac display, if it’s about 220 ppi.

So Apple says a “Retina display” is any screen whose pixel density is high enough that someone with 20/20 vision cannot see individual pixels at the standard viewing distance used for that device.

For the Mac this is about 220 ppi. Larger iPads have a pixel density of 264 ppi, and the iPad mini checks in at 326 ppi. From the iPhone 4 through the iPhone 7, pixel density stayed at 326 ppi, but the iPhone 6s Plus and iPhone 7 Plus are 401 ppi. The tiny Apple Watch screen is about 330 ppi.

If you suffer from eyestrain, reading on a Retina display will likely be easier and less tiring, since the words will be clear and crisp, without any of the fuzziness on the edges that you see on lesser displays.

Last, the words “Retina display” are an Apple trademark. So you won’t see any other manufacturers claiming that their products have Retina displays.

Mac Mail Mystery, starring Verizon and AOL

It was a rainy day in New York City. I emerged from the 1 train at 79th St, for an appointment with EW. She had spent two hours on the phone with Apple, and two hours with Verizon. She was at her wits’ end. Her mail was sometimes disappearing before her eyes from her iPad and iPhone, as if a ghost were moving her inbox messages to her trash.

I surveyed the scene. Two iPads, two iPhones, one Mac. An unusual circumstance: she had a email address. Verizon decided they don’t want to host email any more, so they’ve given that dirty work to their subsidiary, AOL. Every customer with a email address can keep it, but will be checking their mail at AOL. I figured this tricky business could confuse a computer’s mail program, since it’s an AOL in Verizon’s clothing.

The devices looked kosher. They were all set up for IMAP. Synchronized mail. As it should be.

The Mac was another story. It was set up for POP. Downloaded mail, not synchronized. But that alone didn’t explain the disappearing mail. Then I found it: the Mac was set to delete mail from the server, one week after downloading it. Culprit found. I’ve seen it before. I’ll see it again The thing to do was save the downloaded mail into On My Mac, remove the account, add it back as IMAP, and copy the saved mail back into the server folders. Easy peasy.

Except it wasn’t. The Mac insisted that because the email ended in, it had to be set up as POP, because that was all Verizon had offered. Even AOL’s own tech support page said that POP was the only option for people using Apple Mail.

But I don’t take no for an answer from computers. Apple’s done their damnedest to keep you from customizing your Mail setup, but I faked it out by putting in bad account info. Then I got to the manual setup page, and put in the AOL IMAP and SMTP server information with the email address.

The account loaded up. It matched the iPad and iPhone. I left EW breathing easy.

I went to my next client, to work on my next case.

Customize Your Mac Laptop with Skins from RedBubble

I just found out about RedBubble, which sells artist-designed objects including:

  • “skins” for laptops
  • laptop sleeves
  • iPhone cases
  • t-shirts and other clothing
  • home accessories like pillows and mugs
  • stationery items like notebooks and greeting cards

Cooper Hewitt Museum Lets You Save Images with its Pen

I went to the Cooper Hewitt Museum recently and played around with the Cooper Hewitt digital Pen that you can borrow free with admission. The Pen lets you “collect” specific images from your visit to look at later.

Here’s what the Pen looks like (image from Cooper Hewitt site):

You just click it to a wall tag (just like in the image above) and that artwork is saved to your “collection.”

Your admission ticket has a URL and code on it so you can access your “collection” later.

Here are some examples of what the “collection” images look like, compared to mine. (Images on the left are the Cooper Hewitt’s; images on the right are mine. Not all are the identical items….)




The museum images are better if you want flat, full-object views that are perfectly lit. Mine are better if you want to see the pieces in context or zoom in really close.

The best part is that along with the image itself, the museum provides a wealth of detail about the object, including date, dimensions, who owns it, and similar items in the collection.

Of course what the museum really wants you to do with the Pen is share the images via social media, and each image in your “collection” has links for email, Pinterest, Twitter, and Tumblr.

I hope there are future uses for the Pen (and coordinating website with images) that let you do more — think how useful a resource it could be if from this image in the collection you could get links to other sites with other images, historical background, artist info, and so on.

Apple Watch can’t display battery level when you need it

So, get this:

  • If you have an Apple Watch that has been reset to factory state, you can’t do anything with it until you pair it.
  • In order to pair it with an iPhone running a current version of iOS, its own watchOS version must also be current.
  • If you need to update watchOS, you need to use the Watch app on an iPhone. The watch must be on its charger, and the battery level must be at least 50%.
  • But, when it’s in “update” mode, the screen simply shows an Apple Watch logo, and can’t do anything, including show you the battery level.
  • So your iPhone, which has the Watch app, simply says that it won’t install the update until the battery level is at 50%.
  • Meanwhile, the watch is in a mode where it tells you nothing. It can’t even tell you if it’s getting a charge from the charger. There’s no chirp when you attach it, or anything.
  • The Watch app also won’t tell you the battery level, or if the watch is even getting a charge.

So Apple has designed this product in such a way that, if its software out of date, you have to wait a completely unknown amount of time in order to be able to set it up, and your iPhone is tied up during that time. You can’t even know that it will eventually get there, since you can’t see if the watch is getting a charge.

Come on, Apple. You’re the user experience company. Can we have a battery indicator during a watchOS update?

Why you might run older versions of macOS

macOS (or OS X, or Mac OS X, as it has been variously called) has had 13 major versions. Each brings with it new capabilities, but each also drops some older ones as well. Here is a non-comprehensive list of some of the things I might use an old version of macOS for:

10.0 Cheetah, 10.1 Puma, 10.2 Jaguar, 10.3 Panther: These are so old I have no occasion to run them.

10.4 Tiger: Last version to include Classic environment, which enables running MacOS 9 software on Macs with Motorola PowerPC CPU’s.

10.5 Leopard: Last version to support to support printing to AppleTalk printers on a network. Last version that runs on Macs with Motorola PowerPC CPU’s.

10.6 Snow Leopard: Last version to include Rosetta, which enables running software written for Motorola PowerPC CPU’s. Last version to support iSync, which synchronizes address book information via USB or Bluetooth with older mobile phones. Last version that runs on Macs with 32-bit CPU.

10.7 Lion: Last version that runs on Macs with 32-bit EFI ROM.

10.8 Mountain Lion: Last version to support Sync Services, which synchronizes address book and calendar information between the Mac’s Calendar and Contacts applications and other Mac Apps (such as Entourage and Outlook 2011). Last version to support fully manual configuration of Apple Mail.

10.9 Mavericks: Last version that performs acceptably on hard drives (as opposed to solid state drives). Last version to support download headers only in Apple Mail, rather than entire messages.

10.10 Yosemite: Last version to support “unenhanced” iCloud notes syncing used by older iOS versions.

10.11 El Capitan: Last version to support Apple Java 6. Last version to support somewhat manual configuration of Apple Mail settings. Last version that runs on Macs with older wireless hardware (Broadcom 4300 series).
