iMac SMB share?

When I try logging into my iMac share on Infuse 4.2, says user/pw failed.
Is my username Administrator? Or my email address that I use to log into my mac? I’ve tried both, and neither work.

I’m having the same problem. What am I doing wrong?

Try using the name of your home folder.

Check to ensure you have Windows File Sharing enabled in the System Preferences > Sharing > File Sharing menu.

Also, if you using an iCloud ID for your Mac’s login you will need to create a separate ‘Sharing Only’ user as described here.
