Apple Well, to be completely proprietary in Apple's traditions (I would say it's their basic instinct ). Users of Apple production should be quite familiar with that. Perhaps they happy enough with such tradition for Apple to hold its market share still :P For SETI it's another obstacle of course. With possible "no SETI GPU compute on macOS" addition to "No BOINC on iPhones"... SETI apps news We're not gonna fight them. We're gonna transcend them. ID: 1938383 ·

Because there are also Cuda versions (of course the power of Nvidia GPU's are much bigger). Would for example a crowdfunding be possible to achieve this? Sjmielh ID: 1938658 ·

Switching from OpenCL and OpenGL to Apple's proprietary Metal APIs would involve far more than the code to detect GPUs. It would mean that all screensavers / project graphics applications would need to be rewritten (perhaps completely) just for Macs, and all project work applications that use GPU computing would need to be rewritten (perhaps completely) just for Macs. Actually, most or all GLUT APIs were deprecated back in OS 10.9 (October 2013). These are used extensively in the BOINC graphics library: graphics2_unix.cpp, gutil_text.cpp and gutil.cpp. Eric Korpela, Seti@Home jockey wrote: I think this will eventually result in many projects not supporting GPU apps under MacOS. It also might reduce support for OpenCL in the science world in favor of CUDA. ID: 1938696 ·
