As the title says I downloaded the newest release with:

zsync http://www.linuxcnc.org/iso/LinuxCNC_2.9.2-amd64.hybrid.iso.zsync


The output was:
#################### 100.0% 1854.5 kBps DONE

No relevent local data found - I will be downloading the whole file. If that's not what you want, CTRL-C out. You s
hould specify the local file is the old version of the file to download with -i (you might have to decompress it wi
th gzip -d first). Or perhaps you just have no data that helps download the file
downloading from http://www.linuxcnc.org/iso/LinuxCNC_2.9.2-amd64.hybrid.iso:
-------------------- 0.0% 12.3 kBps
#################### 100.0% 7389.8 kBps DONE

verifying download...checksum matches OK
used 0 local, fetched 3472884144

After downloading I ran the MD5 Checksum tool and got:
d541b51f02ecc6f07fe652faa0fc4a2b  LinuxCNC_2.9.2-amd64.hybrid.iso

which is different from the checksum at here

which says it should be

md5sum: 1815aceaac0e7861747aa34d61846e79

Also when I tried to run the whole thing on my PC I could boot into live session but when I started the installer it would just get stuck on a black screen and not do a thing forever.

Okay at least the installation worked now after resetting the BIOS to default settings. Still wondering why the Checksum didn't match...

You're comparing different iso checksums so they won't be the same. The docs are listing md5sum linuxcnc-2.9.2-amd64.iso not the hybrid iso and they also state if you use zsync checking is not needed.

Ah, I'm having a similar problem. I followed the instructions here ((linuxcnc.org/docs/stable/html/getting-st...etting-linuxcnc.html) and the link downloads the hybrid iso. Not using zsync (on macOS). The listed checksums don't match probably for the same reason listed above. Is there another link I should be downloading from or is there a set of hybrid checksum? I did try to add zsync to my LinuxCNC machine and just do the download there but I get a file not found from FTP. 

Thanks,
Steve

Replying to myself.

It turns out there's a zsync port for macOS on Homebrew.
I was able to download using:
zsync www.linuxcnc.org/iso/LinuxCNC_2.9.2-amd64.hybrid.iso.zsync

Note "http" not "https".

The download link produces LinuxCNC... and the instructions call for linuxcnc....
The dd instructions for macOS have the source file at root where the linux instructions start at the current directory. 

I think I have it all sorted. We'll find out tomorrow when the new computer arrives.
