Any help is appreciated!</div><div><br></div><div dir="ltr" data-setdir="false">Below is a list of what I have tried, but I suspect this is some form of permission problem with Mac OS >10.13, that has a new security model. For instance developer need to place their software outside of protected folders that are usually available on other OS's. Also as a user you sometimes need to give apps access to folders, disk and other things in the Security control panel. Another thing could be something strange in the USB-communication, or that maybe the OS is marking the scanner as busy with for some reason ( I have no way of finding that out). But theese are just guesses.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><font size="3"><b>Things I did:</b></font></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><ol dir="ltr" data-setdir="false"><li>Installed <b>sane-backends</b> using <a href="https://formulae.brew.sh/formula/sane-backends#default" class="">Brew</a>.
