GPU Compute Error on macOS 10.13.1
I recognized on several Macs with Radeon Pro 460 and Radeon Pro 580 GPUs that sometimes it says `GPU #0 COMPUTE ERROR`. What exactly does this mean?

Here is an output:

 * VERSIONS:     XMRig/2.4.3-beta2 libuv/1.15.0 OpenCL/1.2 clang/9.0.0
 * CPU:          Intel(R) Core(TM) i7-6920HQ CPU @ 2.90GHz x64 AES-NI
 * ALGO:         cryptonight, donate=5%
 * POOL #1:      xmr-eu.secumine.net:5555
 * COMMANDS:     hashrate, pause, resume
