I am worried Yosemite may slow my macbook down?

I Managed to download the free trial of FCPX and its fine but try to purchase it again this morning and it's still not working

What are your macbooks specs?

I don't think you can go back unless you have a disc if I'm not mistaken and your specs are just a bit different than mine but it looks good a
