eGPU Student Project – By O’Ryan Hampton, Univ of Utah, Marriott Library


An eGPU, short for “External Graphics Processing Unit” which is an idea that has been floating around for years, and in the R&D departments of video card manufacturers for even longer. The general concept involves hooking up a regular laptop to an external graphics card through a single cable, which can then take all of the load off your laptop’s internal GPU and put it on the more powerful extension instead. Apple officially rolled out eGPU support in macOS with the release of macOS 10.13.4. eGPUs requires a Thunderbolt 3 connection to work with Macs, meaning only Thunderbolt 3-enabled Macs are eligible. macOS only supports AMD GPUs, like the AMD Radeon Pro RX 5700 XT or AMD Radeon WX 9100, yet there was one glaring omission with the release — a lack of NVIDIA support. macOS Mojave dropped support for new Nvidia graphics drivers, except for a couple of chipsets included in still-supported Apple laptops. It is rumored that there is historical “bad blood” between Apple and NVIDIA that hasn’t been resolved that prevents driver support on macOS. Several eGPU chassis/card combinations are officially recommended by Apple.

Oracle Java Licensing – By Brad Millett, Univ of Utah, UIT


Java is a programming language and cross-platform runtime environment commonly leveraged in both front and back end IT applications and services. Oracle historically released and supported Java under a license that made it free to use. In 2017 Oracle announced changes to it’s Java licensing and support model and in January 2019 Oracle provided the last free public update/patch-set for Java. As new security and maintenance patches are released, existing Oracle Java installations must either remain vulnerable (i.e. not apply patches), migrate to a new Java installation, or purchase a Java Support Subscription to legally apply any new patches from Oracle.

Due to campus issues network/service issues, Brad Millett had to cancel his presentation. Richard Glaser did a quick ad hoc presentation with video/slides linked below.

Jamf Interaction Toolkit – By David Ramirez


Jamf Interaction Toolkit, commonly known as UEX, is an open-source project that was built with a few goals in mind to setup software deployments that are branded and trusted, consistent across the enterprise, notify the user when applications need to be quit or to not be opened, notify the user when the computer needs to be restarted, allow the user to postpone the action based on number of times instead of an end date. All of this has to be compatible with Jamf Pro and works tandem with Self Service. Over time this tool has grown into a full set of versatile scripts that can essentially be used as your primary method for creating policies. This presentation will give an overview of the Jamf Interaction Toolkit (UEX), setup and implementation and answer questions about it.
