datajar.mobi: A story of Jamf And…

Standard

During JNUC2019, I had the honour of once again presenting alongside my colleague, friend & founder of dataJAR James Ridsdale.

During the talk we released a few GitHub repos with items that we use day-to-day to help our fellow admins. These will be covered in further detail over the few weeks.

Jamf Nation is a community that is very dear to my heart, & over the past decade it’s grown from a small mailing list to over 100k accounts registered on Jamf Nation.

Farewell AutoCasperNBI & AutoImagrNBI

Standard

It has been 5 years since AutoCasperNBI was released, with AutoImagrNBI coming soon afterwards.

However, 5 years is a long time in the world of Apple. And as such, much has changed when it comes to deploying macOS.

NetBoot & Imaging are no longer viable methods for modern macOS deployment, especially when we look at booting off of a network volume to block copy an OS.

As such, today I am ceasing development on both projects & setting their respective GitHub repos as read-only.

In a future episode of the Mac Admins Podcast I go into more detail about the history of how these apps came to be, & I’ll be at JNUC2019 next week raising a glass to both apps.

Jamf Pro critical security vulnerability – PI-007507

Standard

Last night, Jamf released Jamf Pro 10.13.1 & 10.15.1. These were released due to PI-007507. 

This PI is noted as a “critical security vulnerability” which “does not pose a risk to private data or managed devices. It does have the potential to impact the integrity and availability of your web server” but “impacts versions of Jamf Pro 9.4 and later”

As Jamf Pro 10.15.0 was only released 19 days ago, 10.15.1 is the 10.15.0 release with PI-007507 having been patched.

However, for organisations that are still on Jamf Pro 10.13.0 or below due to the move to Java 11 needed for Jamf Pro 10.14.0+, Jamf have released 10.13.1, which is also patched.

Please read the following Jamf Nation post for more information, & if you’re not on a recent Jamf Pro release please also see this post before any upgrades are attempted.
