Can i pause my evaluation licence?

got fed up with trying to find a used computer since none seemed to be properly supported and i did not get any feedback which might help resolving. so i sold them again and i am left with a very old macbook from 2008 which does not run rhino 6. so my question as stated above is it possible? at least till i purchase a new computer with the newest graphics card since these seem to be the only really supported systems.
