That's the limit of recursive macros. You'll have to use a loop instead
of recursion if you want to go further. Something like this:-

#macro Rec (Max)// Parameter is now the number of spheres required
  #local current=0;
  #while (current < Max-1)
    sphere { <0,0,0>, 0.75 pigment {rgb 0.5}
    translate <0,current*0.125,0>
    rotate 55*current*z
    }
    #declare current = current+1;
  #end //while
#end //macro

Rec(300)
