Following the demise of PC-BSD/TrueOS, the most compelling BSD-based desktop operating system with a pleasant out-of-the-box user experience is helloSystem. The helloSystem OS has been aiming to be the macOS of the BSDs and for the past few years has been building a macOS-inspired desktop atop FreeBSD. Out today is helloSystem 0.8 as their newest version built atop FreeBSD 13.1.
The helloSystem 0.8 release continues to focus on being a desktop OS catering to simplicity, elegance, and usability. With the v0.8 release they have re-based against FreeBSD 13.1-RELEASE, improves its launch command, pre-installs the VirtualBox Guest Additions for a better Oracle VM VirtualBox user experience, improved handling for MIDI controllers, initial support for launching some AppImage files using the launch command, and support for recent Intel graphics like Gen12/Xe Tigerlake using the DRM kernel module ported over from Linux 5.10.
With helloSystem 0.8 there is also various user interface improvements, "force quit application" support in the system menu, and a wide range of other desktop infrastructure and UI tooling. The helloSystem operating system is also now shipping with Trojita as its email client, GPU acceleration is enabled for WebEngine-based browsers like Falkon, there is a new "Processes" utility, and a wide range of fixes throughout the platform.
