I recently got this CyberPower UPS for my birthday. I just hooked it up today after charging the battery overnight. The USB cable is attached and OSX recognizes it perfectly. There are a lot of settings/check boxes to choose from. I'm not sure which ones to check and which ones to leave unchecked, being this is my first UPS. I did search the countless UPS threads but my head is spinning. Feel free to link if it's been covered. PS. The unit is advertised being 'pure sine wave' but the box said 'adaptive sine wave'. I emailed CS and they said is was a matter of verbiage and that the two are the same.
