When I install and launch Pulseway on my iMac (mid 2011, 27 inch, CPU i7, Mavericks 10.9.4) in Console is generated periodical error - SMC::smcReadKeyAction ERROR TB0T kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff804814a000. Frequency of error is around 3-6 per second. I tried reinstall Pulsewayq but noting has changed. I have two other iMacs (late 2012), but with them everything is ok.

Can you help me?

any update on this?

I am seeing the same problem on my Mac Mini late 2012
