SPOD, also known as Spinning Pinwheel of Death, is one of the common issues on Mac. If you use your Mac on a regular basis, then you may have encountered it as well. Fixing SPOD is not an impossible task as there are multiple methods to fix it. The Spinning Pinwheel of Death occurs when a Mac doesn’t respond or freezes on a particular app. When it appears, your device is actually trying to function but fails to do so, and in the result, you see a constant spinning wheel.
