I have a makerbot 2x and I am running it on a Mac book

I have a makerbot 2x and I am running it on a Mac book pro laptop. I never had a problem until now. I noticed that when I use the makerbot software to print out my object it is taking so long on the slicing process and it never took that long. What is wrong?

No idea. Try Makerbot support.

The first place you should go is to Makerbot support

Ok thanks

your using a makerbot…

But in all seriousness try uninstalling and reinstalling maybe? MakerWare doesnt have much to play with.
