Among dependencies, the longest to build is (by far) atlas because it compiles tons of different binaries, then test them one by one ans select the one that runs fastest on you computer. So, a good way to accelerate the computation is to tell atlas to do only a single compilation, by setting which CPU do you are running on. In your case, the following generic choice might work, just type this on the terminal before typing make:

export SAGE_ATLAS_ARCH=fast


You will save many hours of compilation. If there is an easy way to install pre-compiled atlas on a mac (no idea), you can avoid to compile atlas at all, by setting the SAGE_ATLAS_LIB variable.

In general, the more you tell about your system, the fastest the compilation will be, see for example how to set the number of CPU's to compile in parallel. There are many options that could be found in the environment variables section of the install manual.
