Can I take the optical drive out of my MacBook Pro? I'm proud to say that I'm the happy owner of an almost antique 2009 MacBook Pro. I've had this 15-inch MacBook Pro for quite a while now and I'm not planning on changing it (have you seen the price of MacBooks these days?). As it is quite old now, it is not really working as well as before and my optical drive doesn't work anymore. It does not recognise any CD and keeps burping them out. It doesn't really matter as I've gotten used to it and don't use the optical drive now.

So here is my question: 

Can I safely take the optical drive out and not replace it with another one?

I know it is possible to take it out and put an SSD in instead but what about just taking in out? And leave and empty space? What about the cables? Can they just hang in there and not be attached to anything?

I'm just thinking it could lighten up my already quite heavy laptop.
Yes, it is possible to remove the optical drive. However, it isn't that easy. You will need several specialized screwdrivers, a tool to remove the cables, and some manual dexterity. If you have experience disassembling laptops it will not be a problem.

Go to ifixit.com and find the instructions for your model. 

Side note #1: this would be a good time to change the spinning drive for an SSD. 

Side note #2: I don't find the price of MacBooks these days to be excessive. Have you seen the junk you get for $500?
