I'm guessing you mean all downloads after the first are being queued. If that is the case then just select the one you want to start, open the context menu (right button if you have one -- do Mac's have one these days), use the "Resume Now" option.
That option means: bypass the download queue, and start immediately.
Of course the permanent solution is to change the queue limit. For that you have to stop the daemon, edit settings.json in either of these lines:
Code: Select all
"download-queue-enabled": true,
"download-queue-size": 3,
You can disable the queue changing the first line, or set a different limit with the second.
