Hello, I just ordered and got a brand new deathadder essential, and I was so excited to use it. I play league of legends on Mac and all I wanted was a great new Razer mouse to play the game with. Turns out the synapse software is incompatible with my Mac running on the latest apple software and rendered my mouse useless since I cannot customize it and it moves accelerates randomly during gameplay. This was very depressing and for a company with so much money and such a high quality standard I find it quite ridiculous and pathetic that they cannot keep their software up to date and compatible with Mac users. Please read this and update the software as soon as possible. All we want is to buy Razer products and be able to use them on Mac.
