Lumin U2 mini music streamer

Just purchased the Lumin U-2 mini and I am in the process of the 30 day free trial period. Very hard to add a single track to my playlist.  Dealer advised there are two ways to accomplish this as follows:

1. Add an entire album to playlist and delete the tracks you do not wish on the playlist.

2. Type in the track desired and add to playlist. 

Both take an inordinate amount of time to accomplish, especially on a small screen.

I am also having a problem as my Apple IPAD is only 10 inches. Would like to

work with a larger screen as the screen is very small to my eyes. The apple I pad that is 12.9 inches is not enough of an improvement in size.

Lumin's owner's manual states that they are compatible with Android and IOS, no mention of the MAC operating system which run their lap tops.

If I purchased an Apple laptop with a larger screen, would the Apple laptop operating system work with the Lumin U2 mini, as the laptop operating system does not use IOS?

By the way, the Lumin U2 mini,  with a Chord Qutest Dac sounds much better than my Cary CD player (which I use as a transport) with the Chord Qutest Dac.

Thank you for any input and advice.
