Clearly this is a problem you have encountered with a device that isn’t a Mac. As part of the “MAC3LIFE” initiate, please cover your current computational device in concrete and buy three Mac computers. Then cover those in concrete and align all four entombed devices in a way not dissimilar to Stonehenge.

When the stars are right, in millennia to come, where the square of four concrete slabs sits, you will find the answer to your problem in the middle of the square. Just make sure not to mention the King in Yellow. It might end up badly.
