Install update Macbook Pro running Mojave

I have version 1.1.0 on it now and tried to upload the newer update 1.2.0. It seems to go through until I get the following message;

I have no idea what this is about or how to fix it?

Also, (ok I am new to this) I can not figure how to SAVE and EXPORT a modified G-Code file in the 1.1.0 version. I can't even find a save icon.


  • Just download new version from homepage and install. Not sure why sparkle does this on some macs, but I have updated sparkle to hopefully fix that for future releases.
