BOINC 7.8.3 on an iMac running Sierra 10.12.6 for Einstein@Home
GenuineIntel Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz [x86 Family 6 Model 94 Stepping 3]
Number of processors: 4
Coprocessors: AMD AMD Radeon R9 M380 Compute Engine (2047MB)

The following problems occurred with 7.8.3 as well as 7.8.2 and were resolved by reinstalling 7.6.33.

1.) No GPU tasks were being loaded because boinc detected -2GB VRAM, rounded it up to zero and failed the 0.8GB requirement.
2.) After successful completion of a CPU task, Einstein would call boinc_finish(0), which always then resulted in a 'computation error' being returned.

Details of logs and a helpful diagnosis may be found at https://einsteinathome.org/content/o1spot1hi-always-has-computation-error-no-gpu-tasks-seen#comment-162845

I think we'll need to see the messages from BOINC 7.8.3 (Command+Shift+E) after it has started up.
Perhaps that you can find older ones in your stdoutdae.txt/stdoutdae.old files in the data directory, else reinstall 7.8.3 and give those to us. They don't show in the thread you link to, there it shows a different log. The first 40 lines or so will do.

Okay, never mind that. I have found the same problem while researching something else at Seti. Also a lot of AMD Compute Engines, with 4 or 8GB of memory. They all report zero GB. Have forwarded it to the developer.

BOINC 7.8.4 has been released through the normal channels to fix this problem.
