Mac network transfer statistics: Pull from command line

In my session today at MacTech Conference, I shared a tip about viewing the transfer statistics from the Network Utility app.

I also mentioned that I had reverse engineered out how to pull these same numbers from the command line.  A couple people asked me for these commands afterwards, so here they are…

Send Errors…
netstat -I en0 | grep en0 | awk ‘{print $8}’ | sed -n 1p

Receive Errors…
netstat -I en0 | grep en0 | awk ‘{print $6}’ | sed -n 1p

netstat -I en0 | grep en0 | awk ‘{print $9}’ | sed -n 1p

macOS 10.14.1 breaks blank user passwords

The macOS 10.14.1 updater seems to require that all Mac users account have a password, and not left blank.  When updating to 10.14.1, after the reboot, user accounts with blank passwords won’t be able to log in.  If it is the only user account on the Mac, you will need to boot into Recovery and reset the password.

macOS and iOS reboot vulnerability mostly patched

Kevin Backhouse has disclosed a nasty vulnerability he discovered a few months back, that could be used to forcibly reboot any Mac or iOS device on a local network.  He also wrote a proof-of-concept exploit that does exactly that.

Kevin has been working with Apple since last August, and they were able to address this vulnerability (CVE-2018-4407) in the releases of macOS 10.14 Mojave and iOS 12.  Apple has also patched this via security updates that are now available for macOS 10.13 High Sierra and macOS 10.12 Sierra.  Older versions of macOS and iOS remain vulnerable.

Jamf Connect to support Azure AD

At this year’s Jamf Nation User Conference (JNUC) it was announced that Azure AD support will be added soon to Jamf Connect.  Customers that use Azure AD and Jamf Connect will be able to allow users to authenticate into their Macs using their Office 365 username/password.  During new Mac setups this will also allow for immediate login in with Azure AD credentials, skipping the setp of creating a local account on the Mac.

History: Back in November Jamf purchased NoMAD, and rebranded it as Jamf Connect.  Curiously the NoMAD website has not been updated since June, with the exception of the purchase links now redirect to the Jamf website.

Mac Office 2019 is out, confusing versions

Mac Office 2019 is now available to purchase as a standalone product, and to download for qualifying Office 365 subscribers. Curiously Microsoft didn’t significantly change the version of the Office apps to reflect the upgrade. Office 2016 apps go up to version 16.16, and Office 2019 apps start out at version 16.17

Microsoft currently supports running Office 2019 on macOS 10.12 Sierra or later.  Mac Office 2016 will be maintained until October 2020.

Adobe CC 2019 Mac system requirements

The Adobe CC 2019 apps that were recently made available for download require macOS 10.12 Sierra or later.  Previously downloaded versions of Adobe CC apps will continue to run on older versions of macOS, confirmed by this Adobe support article.

macOS 10.14 converts all boot drives to APFS

macOS 10.14 Mojave requires the boot drive be formatted as APFS.  Unlike macOS 10.13 High Sierra, which only converted SSD boot drives to APFS, Mojave will convert any HFS+ formatted boot drive to APFS.  This includes: HHD, Fusion, and SSD.  External drives formatted as HFS+ will not be converted.

macOS 10.14 breaks Boot Camp on 3TB iMacs

If you have an iMac with a 3TB drive, and you’ve configured it with Boot Camp, you may get an error when attempting to upgrade to macOS 10.14 Mojave stating “Installation cannot proceed with Boot Camp configured”.

Apple has posted a support article detailing this issue, with options available for affected iMac models.  Some iMacs with 3TB drives have workarounds, and some do not support Boot Camp with Mojave.

New SMC reset procedure for Macs with T2

The SMC reset process has changed on Macs that have an Apple T2 chip, including iMac Pros and 2018 MacBook Pros.  Apple has posted this new SMC reset process for these models:

  • Choose Apple menu > Shut Down.
  • After your Mac shuts down, press and hold its power button for 8 seconds.
  • Release the power button, then wait a few seconds.
  • Press the power button again to turn on your Mac.
