Hi all, I bought APC BACK - UPS 700VA 230V recently for my iMac (mavericks OS). I have connected the ups to power outlet and iMac's power cable to ups. But i'm facing some issues: 1. Firstly, iMac gets power supply only if i connect to surge protector outlet of ups. If i connect it to battery backup outlet, there's no power supply. 2. But, if i connect my phone charger to battery backup outlet, it works fine. 3. I read somewhere that if mac is connected to ups, we can see 'ups' option in energy saver tab. But i don't see that option in my system. Do i need to connect my mac to ups via usb cable to get this option? What would be the reason for these issues? Can someone please guide me?
