Hi! I understand you're trying to create a playlist in the SenPlayer app on your Mac, but you don't see the option to do so. Let's look into this together.

First, can you confirm if you're looking for a "Create Playlist" button or an option when you try to add media? Sometimes, in certain media players, the playlist creation option appears only when you select media items first.

Here's what we can try step-by-step on your macOS 10.15.7:

1. Select media files: Open SenPlayer and navigate to your media library. Try selecting one or multiple media files (videos or music).

2. Look for an Add or Plus icon: Once media items are selected, check if a "+" or "Add" icon appears somewhere in the interface (top or bottom). This icon might open a menu that includes "Add to playlist" or "Create new playlist."

3. Right-click option: If you don’t see any icon, try right-clicking (or Control-clicking) on the selected media files to check if there's an "Add to playlist" or "Create playlist" option in the context menu.

4. Check app menus: Look over the main menu bar at the top of your Mac screen while SenPlayer is active. Sometimes playlist commands are in menus like File, Edit, or Media.

If none of these steps show a playlist creation option, it is possible that the current version of SenPlayer does not support creating playlists directly in the app on macOS, or the feature might be limited.

Could you tell me which version of SenPlayer you are running? Also, did you update it recently? This info will help me confirm if the feature is expected to be there or if there's a workaround.

Meanwhile, just so you're aware, some users have found that the playlist feature might be limited or accessed differently depending on the platform or version. It's worth checking if the latest update has introduced changes related to playlists.

Let me know what you find after these steps or if you'd like me to help further! Are you satisfied with the guidance so far?

I’m using Jellyfin and the SenPlayer as a Client

Thanks for clarifying that you’re using SenPlayer as a client for Jellyfin on your Mac. That helps a lot in understanding the context!

To address your question about setting up SenPlayer with Jellyfin and specifically about creating playlists, here’s a general guide and some insights:

1. Ensure Jellyfin Server is Properly Configured
- Your Jellyfin media server should be up and running and accessible from your Mac.
- Make sure you have user credentials to log into your Jellyfin server via SenPlayer.

2. Connect SenPlayer to Jellyfin
- In SenPlayer, you should find an option to add a media server or enter server details.
- Input the Jellyfin server URL and your login credentials to establish the connection.
- Once connected, you should see your Jellyfin media library within SenPlayer.

3. Playlist Functionality in SenPlayer with Jellyfin
- Unlike standalone players, playlist creation and management might be more limited or handled by the Jellyfin server or your account rather than the SenPlayer client.
- To create playlists, you often need to use the Jellyfin web app or a dedicated Jellyfin client that supports playlist management directly on the server.
- In SenPlayer, playlist support may be limited to playing existing playlists or creating temporary play queues rather than saving persistent playlists.

4. Workaround for Playlist Creation
- Create playlists within the Jellyfin web interface first. Jellyfin supports creating and managing playlists online.
- Then, access those playlists in SenPlayer since it syncs with the Jellyfin server.

5. Check for SenPlayer Updates or Extensions
- Look for updates to SenPlayer that might improve Jellyfin integration, including playlist features.
- Sometimes third-party plugins or add-ons enable extended playlist functionality.

Since there isn’t an official SenPlayer-Jellyfin setup guide publicly documented right now, I suggest checking these Jellyfin resources for more details on playlist creation on the server side:
- Jellyfin official docs: https://jellyfin.org/docs/general/quick-start/
- Jellyfin community forums or Reddit for user-shared tips and playlist strategies.

If you want, I can help guide you through creating playlists on the Jellyfin web interface or check if your SenPlayer version has any playlist options I might have missed.

Does this make sense so far? Would you like me to assist you with the Jellyfin playlist creation side or explore SenPlayer’s menu and settings in more detail? Are you satisfied with this explanation?
