Hi Guys! I'm trying to share a folder on my Mac with my home network that has some Windows PC's on it too. So far I have been able to share the folder and see it on my Windows computer, and view the files, but I can't delete or copy stuff TO the iMac from the Windows computer because I can't change the user permissions on the Mac. The permissions are all grayed out and I can't even click on the +/- buttons below it to try to delete-and re-add the users in hopes of maybe getting them to not be grayed out anymore.
There also isn't a "lock" icon for me to click on to lock/unlock the ability to make changes, like I've seen in some screenshots. Here's a screenshot of my screen showing what's happening, can anyone help?
