Why does the StarTools crash under heavy load on my older macOS device?

If StarTools appears to be unstable on your older (up to 2014) macOS device, particularly when using bigger datasets, then this may be due to an underpowered iGPU solution. Particularly the second and third generation Intel-based macOS devices are equipped with minimal GPU acceleration.

In such cases, the intergrated GPU may get overwhelmed and time out causing a watchdog to reset the graphics driver. If this is the case, then the best course of action is to force StarTools to use the CPU, rather than the GPU. To do so, create an empty file named 'openclforcecpu.cfg' (case sensitive - e.g. all lower case) in the StarTools folder.
