If anyone wants to run Watchpower on a Mac, and hasn't been able to get it to work, I found that the Mac needs to be connected to the Inverter's RS232 serial port rather than the USB port. To do that get a USB to Serial adapter - but make sure it has the FTDI chip set and not the Prolific chip...

Oh. That 'Parallels'. I just don't understand is why I can't find posts from anyone claiming to be successfully using Watchpower on a Mac - no less posts explaining what version of Watchpower or Mac OS they use. When I asked MPP Solar if they've ever seen Watchpower running on a Mac, and what...

Not sure what you mean by "parallels". Do you mean Watchpower for Mac won't work if the inverter system is in 'parallel' config? Mine is 2 units in 240v I have it running on a Windows machine now. But the Mac is my always on machine, and I have other inverter software that runs on it; and don't...

Has anyone figured out if any versions of Watchpower for MAC work with any Mac OS? I just spent 7.5 hours with an MPP tech going through my computer, only to have MPP tell me that (in order to solve the problem) they need a neck to connect with my computer. I keep telling them that a Windows...

I've tried the Watchpower Mac version that MPP has on their website. But I've also tried some older ones - and they all do the same thing. Perhaps they weren't old enough; as Sierra 10:12 came out in Sept of 2016. Thanks for the suggestion.

Haven't a clue what anything in the appended lines mean (gotten from the path you said to check), but it appears to involve "usbserver". so maybe its relevant to the problem being that the computer/inverter connection is via USB. I abbreviated the 3rd section as it started repeating dozens of...

The Watchpower app launches on the Mac computer, but the displayed data fields are empty (just zeros or default settings) - just like when Windows initially launches the Watchpower app. Except, with Windows, those fields and settings eventually fill with the current data from the inverte. But...

Does anyone know what is required to get WATCHPOWER software to operate on a Mac computer, connected via USB; (using LV5048 in parallel)? I can get it to operate on a PC running Windows 10. And it will launch on my 13" (2011) Mac PowerbookRro running Sierra (10.12.6) - but it does not connect...
