Hi, I basically record cold voice and only need mono output...but I don't like that I can only have right channel or left channel unless I put the output to stereo. How can I sum the output so it comes out of both speakers, but is still a mono output?

Make sure your channel strips are mono but clicking on the circle below the channel strip. If there are two interlinked circles it is a stereo channel. If it is one circle it is a mono channel. You can do the same with the master output and convert it to a mono channel as well.

I'm not sure I'm doing it correctly. If I record and save track as mono out...(Chan 1 or 2) it only plays in one speaker...even after I've gotten rid of the circle below the channel strip. If I take a file that I've recorded in one channel, hit the switch on the channel strip...it switches to Stereo Out...

You could use the Gain plugin under the Utility section in Logic There you can choose to make the channel strip Mono on the plugin. Now bounce out the track and the signal to the left and right should both be the same. What are you wanting to do with the mono track?

I usually just record cold voice...no other added product...and since it's cold voice I don't need to have it stereo...since I'm also trying to have manageable file sizes it's what I need to do
