cyrus-sasl-xoauth2 VS isync

no you need to install both cyrus-sasl and some form or another of xoauth, such as https://github.com/moriyoshi/cyrus-sasl-xoauth2. If you're on a mac you should look at this issue: https://github.com/moriyoshi/cyrus-sasl-xoauth2/issues/9

Unfortunate things 2: it seems that even once you have cyrus-sasl installed, there might not be a standard, widely-distributed XOAUTH2 plugin. The one I found referenced the most often and ended up installing myself was here. It took me a lot of fiddling with the configure.ac file to get it to install the plugin to /usr/local/lib instead of /usr/lib, because, again, Apple does not want me to do things the default Linux way, because of reasons.

Any luck? I've been able to build cyrus-sasl-xoauth2 and install it correctly (I had to call the correct prefix during the configure call). I have avoided the callback: 18948 error by building isync from here: https://github.com/xukai92/isync/. Though now I'm getting an IMAP command 'NAMESPACE' returned an error: BAD User is authenticated but not connected error. So 🤷‍♂️
