Rendering tiles on Mac OS 9.2.2

I would like to render tiles on Mac OS 9.2.2 so that I don’t rely anymore on a PC. This operating system has limited capabilities. It draws horizontal text and no antialiasing for example, but it does have OpenGL 1.2, but this is slow when rendering large pictures. With QuickDraw GX it can draw text on a path but no antialiasing. I can have a sort of antialiasing by drawing offscreen at 200% and then scale to 50%.

The main problem however is to convert the OSM data into drawing instructions. I see that there are nodes and ways, but I expect that there will be problems with for example dead ends and intersections, that it will look bad and unprofessional. Is there a general description of the algorithm for rendering tiles so that all streets look like neatly connected?
