I haven't been getting any tasks for Intel CPUs or NVIDIA GPUs in Macs. I detached and reattached to Collate. I get the following messages in my log:

Thu Apr 26 08:43:54 2018 | collatz | Sending scheduler request: To fetch work.
Thu Apr 26 08:43:54 2018 | collatz | Requesting new tasks for CPU and NVIDIA GPU
Thu Apr 26 08:43:55 2018 | collatz | Scheduler request completed: got 0 new tasks
Thu Apr 26 08:43:55 2018 | collatz | No tasks sent

Any ideas or advice? All of my crunchers are Macs, so this is a big deal for me.

Mostly Mac here too :(

There are no Mac/Linux apps for Collatz yet -- so it's Windows only until you see the apps listed under the Computing => Applications menu.

I've switched to another project temporarily to keep the GPUs busy and the RAC from plummeting.

Short answer: Be patient. They are coming.

Long answer: The MAC and Linux apps use the same code base since they are both compiled with GCC. The apps use 128 bit and 256 bit numbers and I'm working out the kinks with making sure that the optimizations work on all machines and not just the one it was compiled on. e.g. If I use a really old version of GCC and Linux, it works on all later machines. But to compile the OpenCL with the latest SDKs, it needs newer versions which means it won't work on older machines. So, OpenCL 1.1 and 1.2 optimizations may not be available which leads to tens of thousands of errors a day. The end result may be that they won't work quite as fast but will work on most hosts. All hosts is the target, but I don't think that is ever obtainable given how new video drivers often break things and then get fixed in a later version.

Thanks for the update and explanation, Slicker. Will continue to sit tight. I can only guess at the challenges you are facing.
