When using Fluid Remote Desktop protocol to connect to a Mac you can not switch between user sessions using the Mac's Fast User Switching menu. We're aware of this issue and are working on a fix.
To workaround this limitation, simply create a new connection to the Mac and use the other user's credentials to log in when Fluid prompts you for Mac Credentials:
- On the device you're connecting from create a Duplicate connection entry for the Mac you want to connect to: Right click the connection and then click Duplicate. On iOS, Android, tap the blue icon next to your connection's name and then create a duplicate.
- Edit the duplicate connection and make sure 'Auto Logon' is blanked out.
- Connect to Mac using the duplicate connection entry and enter the other user's credentials when prompted for Mac Credentials.
Tip: You won't need to disconnect the original session while connecting to the new user's desktop. When connecting to Macs, Fluid Remote Desktop supports multiple simultaneous sessions / users per Mac.
