The simplest way 'around this' is to get a newer computer with a
Metal/Metal 2 compatible GPU.
The harder way is to try & replace the GPU inside the MacBook with a Metal/Metal 2 compatible GPU and then see if it will allow you to install the later OS (or try
dosude's patched installers).
If the GPU on your machine is part of the CPU (e.g. HD3000) then the answer is probably no. If it's a discrete GPU like a Geforce 320M then there 'may' be a path, but I don't know what or how difficult it would be - probably better to ask in the machine-specific area of this forum.
