Tags are clearly visible in List view, for example, but not so obvious in the Icon view. The other notable limitation is the type of view your colleagues are using. If you’re working in a mixed-platform environment, it’s probably best not to rely on the macOS tags.
If you’re viewing the folder in the Dropbox app on a smartphone or on a Windows PC, the tags won’t be visible. Firstly, those tags will only be visible to other macOS users. However, there are some limitations here. That means if you add a tag to a file in macOS, other macOS users sharing that Dropbox folder should see that tag on their systems. The good news is the answer is yes – Dropbox does indeed support the extended attributes in which Apple’s tags are stored. However, you might be wondering whether macOS tags work with Dropbox, so that if one of you marks a file with a green tag, say, others who have access to that same Dropbox folder will see it? You can, for example, mark different files in a folder with coloured tags to show their current status – a green tag indicating that the file is ready to send, for example. Tags in macOS can be very handy when you’re working on a project with different people.
