Only 64-bit Apps Will Work On iOS 11

Be sure to think twice before upgrading to iOS 11 when it's released this fall. The new operating system works only as 64-bit architecture and your installed 32-bit apps will no longer function after you upgrade until the apps have also been upgraded to work as 64-bit by their developer. Here's what Apple wrote to app developers.

64-bit Apps on iOS 11

June 28, 2017

App StoreAs a reminder, new iOS apps and updates submitted to the App Store must support 64-bit. Support for 32-bit apps is not available in iOS 11 and all 32-bit apps previously installed on a user’s device will not launch. If you haven’t updated your app on the App Store to support 64-bit, we recommend submitting an update so your users can continue to run your apps on iOS 11, which will be in the hands of hundreds of millions of customers this fall.

Two-Factor Authentication Required For iOS 11

Apple will automatically migrate iCloud users to two-factor authentication when they upgrade to iOS 11 or macOS High Sierra.

Apple says its “most advanced” account security is required to use some of the latest features of its operating systems, so it’s no longer optional if you plan on updating your devices.

Apple this week began notifying users who already use two-step verification that they will be migrated to two-factor authentication upon upgrading, MacRumors reports. Although the two systems are similar, two-factor authentication is even safer.

The two-step verification, launched in 2015, requires you to enter a six-digit code when signing into your iCloud account on a new device. That six-digit code is sent to another trusted device tied to your Apple ID and requires iOS 9, OS X El Capitan, watchOS 2, tvOS or later.

Two-step verification simply sent a four-digit code to any trusted device that could receive an SMS. What’s great about two-factor authentication is that it allows you to view the location of a new device attempting to access your iCloud account.

“If you install the iOS 11 or macOS High Sierra public betas this summer and meet the basic requirements, your Apple ID will be automatically updated to use two-factor authentication,” Apple explains in its email to users.

“This is our most advanced, easy-to-use account security, and it’s required to use some of the latest features of iOS, macOS, and iCloud.

“Once updated, you’ll get the same extra layer of security you enjoy with two-step verification today, but with an even better user experience. Verification codes will be displayed on your trusted devices automatically whenever you sign in, and you will no longer need to keep a printed recovery key to make sure you can reset a forgotten password.”

It’s not totally clear whether two-factor authentication will be required for all users who update to iOS 11 and macOS High Sierra — or whether it’s only necessary for those who already use two-step verification.

Some of the worries mentioned so far:
  • How will schools manage multiple student iPads?
  • What if you live in a country where Two-Factor Authentication is not available?
  • How will I admin my relative's iPad who lives overseas?
  • What if you only have one Apple device?

Create a Bootable Install USB Drive of macOS Sierra

If you have multiple computers that need the macOS Sierra upgrade, you'll want to create a bootable install flash drive. The download for macOS Sierra is about 5 GB, and could take some time downloading on each computer individually. So downloading it once and making a bootable USB drive is an easier, faster way to go.

1. Download the macOS 10.12 Installer
Download the macOS 10.12 Sierra from the Mac App Store (HERE) - but don't install it when it finishes downloading. If you do, it will auto-erase the file when your system gets back up and running, which means you won't have the file for your USB drive. So, close out any installation screen that pops up.

2. Get 'Install Disk Creator'
After downloading the app (HERE), unzip it, then open it up. When the popup appears, hit Open. (You may need to adjust your Gatekeeper security settings.)

3. Select Your USB Flash Drive
Use a USB flash drive with at least 16 GB of total space. It's possible an 8 GB one will work, but there have been issues with using 8 GB drives for more recent Mac installer files. The following process will totally wipe your USB flash drive, so make sure that you back up all of your important files, if any, before proceeding. When ready, select your flash drive in the drop-down menu in Install Disk Creator.

4. Choose Your Sierra File
Install Disk Creator will automatically detect your "OS X" installer file. If you have an old installer file from El Capitan or Yosemite installed, you might have to choose "Select the OS X installer" button, then navigate to your Applications folder and select "Install macOS Sierra."

5. Erase and Create the New Disk
When ready, just hit the "Create Installer" button. You will need to enter your admin password to continue. As mentioned, this will erase your flash drive and turn it into a bootable macOS Sierra drive. So this is your last chance to stop and back up any important files on your flash drive before continuing. When the bootable drive is ready, you'll see a popup telling you so. The whole process takes about 6-7 minutes.

6. Install macOS Sierra on Your Computer
Now that you're all set, it's time to install Sierra on your computer. Most devices are supported, but just in case, check out the basic list of Macs you can install Sierra on below (for features requirements, see here). Also, you'll need OS X 10.75 or later, 2 GB of memory, and at least 8.8 GB of available storage to upgrade your computer.
  • MacBook (Late 2009 or newer)
  • MacBook Pro (Mid 2010 or newer)
  • MacBook Air (Late 2010 or newer)
  • Mac mini (Mid 2010 or newer)
  • iMac (Late 2009 or newer)
  • Mac Pro (Mid 2010 or newer)
With your bootable USB drive inserted in your computer, restart your Mac, then hold the Option (alt) key down on your keyboard until the Startup Manager appears. Select the macOS Sierra drive to continue. The macOS Utilities will open. Just select "Install macOS" from the list of options, then follow all of the on-screen prompts to start the installation process. After that, all you have to do is wait for it to boot back up with your new Sierra operating system!
