Apple releases macOS High Sierra Supplemental Update; patches security flaws

Apple released a macOS High Sierra Supplemental Update today which “includes improvements to the stability, reliability and security of your Mac,” according to the software update release notes.

The release notes further state that the update:

  • Improves installer robustness
  • Fixes a cursor graphic bug when using Adobe InDesign
  • Resolves an issue where e-mail messages couldn’t be deleted from Yahoo accounts in Mail

macOS High Sierra Supplemental Update

The supplemental update also patches two significant security flaws recently identified in macOS High Sierra.

macOS High Sierra 10.13 Supplemental Update

The first security flaw involves Disk Utility and APFS encrypted volumes where a password could be improperly stored as the hint if a hint was setup in Disk Utility during the creation of an APFS encrypted volume.

Apple’s article regarding the security content of macOS High Sierra Supplemental Update states “If a hint was set in Disk Utility when creating an APFS encrypted volume, the password was stored as the hint.”

The second flaw could allow hackers to use malicious third-party applications to extract keychain passwords. According to the same article “A method existed for applications to bypass the keychain access prompt with a synthetic click.”

Apple recommends all macOS High Sierra users install the macOS High Sierra Supplemental Update. Users can download and install the free update by going to the App Store, selecting “Updates” and then clicking on “Update” next to the macOS High Sierra 10.13 Supplemental Update.


Wacom Tablet Users: Hold off on upgrading to macOS High Sierra!

If you’re a Mac user and rely on your Wacom tablet, you may want to hold off on upgrading to Apple’s latest operating system – macOS High Sierra. According to Wacom, the current Wacom driver for macOS Sierra (Apple’s previous generation operating system) is not compatible with macOS High Sierra (Apple’s latest operating system). Wacom is working on a new compatible Wacom driver for macOS High Sierra and expects it to become available by late October.

Wacom posted the following statement regarding Wacom driver compatibility with macOS High Sierra:

“Apple has released 10.13 High Sierra on September 25th. Wacom is currently working on a new driver update to support the new operating system. The new Wacom driver will be ready by late October at the latest. Due to nature of the changes in High Sierra, the existing Wacom driver for 10.12 will not work. To continue to use your tablet uninterrupted, Wacom suggests not to upgrade to 10.13 until the new driver is released.”

If you’ve already upgraded to macOS High Sierra and are experiencing compatibility issues with your Wacom tablet, hang tight! Wacom is working on it!

Create a macOS High Sierra Bootable USB Installer using Terminal

Using Apple’s “Terminal,” you can create a macOS High Sierra bootable USB installer. This installer can be used to perform a clean installation of macOS High Sierra on a compatible Mac.

macOS High Sierra is compatible with the following Macs:

  • 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)

For a detailed list of macOS High Sierra system requirements, visit the link below:

To create the macOS High Sierra bootable USB installer:

First, download the latest version of macOS High Sierra from the App Store. When the download is complete, the macOS High Sierra Installer application will launch. You can close the Installer application. Locate the macOS High Sierra Installer in the “Applications” folder of your Mac HD. The file will be called “Install macOS High Sierra.” Leave the macOS High Sierra Installer in the default location. This is important for later on.

Next, connect a USB Flash drive to your Mac. The USB Flash drive should have a storage capacity of at least 8GB. Make sure the USB Flash drive does not contain any files or documents you wish to keep. As part of the process to create a bootable USB Flash installer for macOS High Sierra, the USB Flash drive will be formatted (all data will be erased). Once the USB Flash drive is connected and has mounted onto your desktop, change the name of the drive to “Untitled.” Again, this is important for later on.

Launch “Terminal.” You can do this by going to the Finder, select “Go” from the menu bar then “Utilities.” Within “Utilities” double-click on “Terminal.”

Copy and paste the command line below into the “Terminal” window. Be sure to copy the command line accurately and in its entirety.

sudo /Applications/Install\ macOS\ High\ –volume /Volumes/Untitled –applicationpath /Applications/Install\ macOS\ High\

After pasting the command line, “Terminal” will prompt you for your computer’s password. Enter your password then press the return/enter key on your keyboard. You must use an account with Administrator privileges.

“Terminal” will ask you to confirm that you want to erase the USB Flash drive. Enter “Y” for Yes then press the return/enter key on your keyboard. “Terminal” will format the USB Flash drive (you will see the message “Erasing Disk: 0% . . . 10% . . .”) and then proceed with copying over the macOS High Sierra Installer files and make the USB Flash drive bootable (you will see the message “Copying installer files to disk . . .”). This process may take some time to complete so be patient. Once the process is complete, “Terminal” will display “Copy complete” followed by “Done” and take you back to a Terminal command prompt. If there are no error messages, you can close out of “Terminal.”

Your macOS High Sierra bootable USB Flash drive should now be ready. You can test the USB Flash drive by restarting the Mac and holding down the Option key during restart. On startup, you should be prompted to select the drive that you want to boot from (either the internal hard drive/SSD or the USB Flash drive). Select the USB Flash drive to make sure the drive works properly. After the USB Flash drive boots successfully into the macOS High Sierra Installer, you can exit the installer, restart the Mac and boot normally to your internal hard drive/SSD.

Additional Notes:

  • After downloading the macOS High Sierra Installer, make sure to leave the Installer file in its default location (the “Applications” folder). The Terminal command line will not work if you move the Installer file.
  • Make sure the USB Flash drive is renamed to “Untitled.” The Terminal command line will not work if the USB Flash drive is named differently.
  • If you are having problems creating a macOS High Sierra bootable USB Flash drive using the current USB Flash drive, try a different USB Flash drive. Some USB Flash drives may be problematic.

Support for 32-bit apps To End in iOS & macOS

Earlier this year, Apple announced that it would begin to phase out support for 32-bit apps in both iOS and macOS.

Starting with the release of iOS 11 in Fall 2017, iOS will no longer support 32-bit apps. 32-bit apps will disappear from the App Store and users attempting to launch existing 32-bit apps on their iOS devices (devices which have been upgraded to iOS 11) will receive a notification that the 32-bit app is no longer supported and must be updated by the app developer in order to work with iOS 11.

Users can check their iOS devices to determine which apps, if any, are 32-bit. To check on an iOS device, go to Settings | General | About | Applications. If your iOS device is running any 32-bit apps you’ll be able to click on “Applications” and get a list of those 32-bit apps. If you are unable to click on “Applications,” your iOS device should be running 64-bit apps.

As for macOS, macOS High Sierra will be the last release of macOS that will support 32-bit apps “without compromises” according to Apple. Starting January 2018, all new apps submitted to the Mac App Store will be required to support 64-bit and then in June 2018, all apps and updates in the Mac App Store will be required to support 64-bit.

Users can utilize the Activity Monitor or System Report in macOS to determine if a Mac is running 32-bit apps.

Using the Activity Monitor

  • In the Finder, select Go | Utilities then launch “Activity Monitor.”
  • After the Activity Monitor window opens, select View | Columns and make sure “Kind” is selected (checked).
  • Sort all processes by “Kind” (click on the column header for “Kind” to sort) and make note of any 32-bit apps.

Using the System Report

  • In the Finder, select the Apple menu then “About This Mac”
  • In the “About This Mac” window that opens, click “System Report”
  • In the left-hand column, scroll down to “Software” then select “Applications”
  • Once the list of applications populates (this may take a moment), sort the list by the column labeled “64-Bit (Intel)” (you may need to expand the window to see this column)
  • A “No” in the “64-Bit (Intel)” column means the app is a 32-bit app. Make note of all 32-bit apps.

If you are running 32-bit apps on iOS or macOS, you’ll want to check with or contact the app developers to see if and when a supported 64-bit version will become available. While some app developers may release updates to their apps to support 64-bit, some may not. For any apps that will not receive an update that supports 64-bit, you’ll want to plan ahead.

Microsoft To End Support For Office 2011 for Mac

With the upcoming release of Apple’s macOS High Sierra in Fall 2017, Microsoft has officially announced that it will end support for Office 2011 for Mac on October 10, 2017.

The official end of support means Microsoft will no longer release any new software updates (critical or not) nor provide technical support (free or paid) for Office 2011 for Mac on or after this date. Microsoft has also stated that they have not tested Office 2011 for Mac for compatibility with macOS High Sierra nor do then plan to officially support the latest version of macOS.

Current users of Office 2011 for Mac can upgrade to Microsoft’s latest version of Microsoft Office for the Mac, Office 2016 for Mac, to continue receiving updates and support. However, upgrading to Office 2016 for Mac won’t guarantee 100% support and compatibility with macOS High Sierra, at least not yet. Microsoft Office does not officially support macOS High Sierra while the macOS is in beta.

As with its predecessors, Microsoft Office will likely receive a batch of software updates to make it compatible with and supported in macOS High Sierra; though it’s unlikely to happen until High Sierra reaches final release or RTM.
