Hello everyone, I have an old black Macbook: Processor 2GHz Intel Core Duo Memory 1.25 GB 667 MHz DDR2 SDRAM Hard Drive has 74 GBs total(55GBs occupied) I wish I could purchase a new and powerful Mac, but I have to wait for better times to come. In the meantime, I wander, what there would to be done to speed up a bit my "old friend" ? Thanks P.S.: It's especially frustrating when I have to use Maple for a 3D multivariate function plots. It takes forever or doesn't plot anything at all in the end.
