Hey I had the same problem but think I worked it out.
More and more Mac experts are weighing in on the idea that OS X quality has declined and has become noticeable and annoying in Yosemite. This is a new, uncomfortable feeling that Macintosh. The text was updated successfully, but these errors were encountered.
Open a new track, choose 'software instrument' and then towards the left hand side of the top navigation bar click the dial icon (in between the question mark and the scissors). This will bring up the 'smart controls' that replace the stuff that used to be on the 'edit' tab; in this version they're designed to look like the sort of amp you would have depending on the type of track or instrument you've selected.
Not every instrument has the same settings but if you look in some of the synth bass instruments mess about with things like 'pulse' and 'rate' to make the wobble bass sound.

The automation then has the same settings as the amp so if you get the sound how you want it on the amp then use automation to change the 'rate' you can get the dubstep wobble sound.

Hope that makes sense!
