The Raspberry Pi image is built from their kernel so its not a generic ARM64 image (I built it)
The ISO on the Downloads page includes everything you need to run linuxcnc. (I also built this image)
At one stage Linuxcnc was deployed via the Debian build system. That is no longer the case. The ARM64 image was built by Debian and there is no guarantee it will work. Its quite old predating the 2.9.1 release.
The AMD64 ISO image on the downloads page is a customised version of the Debian Live installer. It installs the PREEMPT_RT kernel and XFCE desktop and the which is the best for Linuxcnc of the many available. We want users to succeed.
Please take our advice and if you don't know what we are talking about when it comes to Linux, Google will show you the way. We don't have time to provide Linux support.
And you have been using Linux all the time, Mac's run Linux, iPhones run Linux, Android is Linux. All the worlds servers run Linux.
It just looks and feels a bit different in each case.
mac and iphone have nothing to do with linux,
both are based on darvin (BSD), not linux !
