Hello,
 
I bought individually powered studio monitors for mostly listening to stuff. I do not feel like spending another hundred dollars for a usb interface.
 
The two types of inputs accepted by the monitors are xlr and trs. I would like to plug in and switch between my macbook and my cd player if possible.
 
How can this be done?

I guess you will be using the TRS inputs, not the XLRs
What is the make and model of the Studio monitors?
What is the make and model of the CD player?

The CD player has standard RCA outputs. The model of the studio monitors are M-audio BX5 D2.

Use this RCA to TS cables should connect the CD player to the BX5s.

And this adapter to use with the first cable for connecting the BX5s to the Macbook.
