Hello. What does failed CPU 7 mean on my Mac? I've restarted, nothing is working. Been like this for days.
Thanks everyone!
Stay safe and healthy!

Re: Failed CPU 7
Welcome to the forums Brenda !!
If you could post your log (including top 100 lines or so that show the configuration along with a sample of the error) and someone may be able to assist diagnose/resolve the issue you are having … For guidance on posting logs see viewtopic.php?f=61&t=26036.
I'll guess that your mac has 8 cores (or four cores/8 threads) and is the CPU slot is set up in "auto" configuration (-1) which allocates the CPU slot the total thread count less one for each graphics card … so CPU: 7 would refer to that having an issue - but the log will help get it sorted out.

Re: Failed CPU 7
Welcome to foldingforum.org, brendalcampbell
The software that uses the CPU to process WUs, called Gromacs or FAHCore_a7, divides the WU up into segments and assigns a segment to each CPU so they can process the forces and motions of the atoms in parallel. I does not work when there are 7 segments or other prime numbers. This number varies when you move the slider, but it also can be adjusted with the FAHControl program. You probably have a CPU that supports 8 threads. (if you post the first couple of pages of FAH's log we can confirm that guess.) Moving the Power slider to Full will probably correct this error.
