The Mac Pro 2013 has had a few firmware upgrades. Unlike previous Mac Pros, where a firmware upgrade allowed for faster CPUs/RAM, AFPS, and NVMe booting for certain models, the Mac Pro 2013 has been meager. The MP61.0120.B00 boot ROM included support for NVMe booting (found in the High Sierra update). Most recently, the boot ROM version 22.214.171.124.0 was included in the 10.14.4 Developer Preview. With some firmware upgrades, some users found 4k displays no longer supporting 60 Hz, which requires an SMC reset and removing the offending PLists. See the useful links below. Previously the updates were distributed separately from the OS , but in 10.13+. they have been distributed with OS.

Update 10/27/2021: The latest firmware update has added an auto low-latency mode. The TV will automatically switch to 'Game' mode when you start playing a game from a supported console.
As a multi-platform solution, J-Trace PRO Cortex-M comes with the setup and control software for Linux, macOS and Windows. Software and firmware updates are included. Similarly, use on all currently supported target devices, and any that will be added, is also included. 2b1af7f3a8
