New update available Mac OS

G-Sender says I have update but when I try to load it it won’t download. I don’t have internet in my shop but I do in my house. When I try to load in my house it still won’t load. I loaded previous version before I even got my long mill. I don’t have to have the machine hooked up do I?

Definitely not. Just download afresh and then use a USB stick to transfer it. BTW just in case, since you’re also on a Mac, I learned about a very obscure incompatibility between OS X 10.11 and USB Arduino is fixed by using a hub in between. I am running Gsender on 10.11.5 on an old iMac controlling the long mill, I can control remotely with screen sharing from my OSX 10.14.6 laptop.
