I originally posted this on Broken Forum but the process bugged me so much that I feel obligated to repost it here.
I hooked up my Deathadder 2013 edition mouse to my MacBook because I switched over to a Logitech 700s on my PC and was no longer using the Deathadder there. Using the built-in drivers the Deathadder seemed a bit twitchy on the Mac, with the cursor often leaping from the external monitor back to the laptop’s display. I decided to install the much-maligned Razer Synapse 2.0 driver configuration thingie, which requires you to be online (initially, at least).
First I had to create an account. The system kept telling me that my chosen username and/or password were bad without providing any details as to why. I finally figured out it didn’t like special characters in passwords. What is this, the 1890s? Anyway, I got to where the account was created and apparently missed a verification email with a link I had to click on (because the page made no mention of it). I tried my username/password combo, knowing it was correctly entered but again the system kept saying it wasn’t (due to the aforementioned unmentioned verification requirement).
Here’s the best part, though: after several “unsuccessful” attempts I was locked out.
Of a driver.
I could not configure my mouse unless I waited at least five minutes first. At that point the system would generously grant me the privilege of entering my username and password again.
Instead I uninstalled the software and made a promise to myself to never buy another Razer product. (The uninstall naturally did not allow me to just drag the icon off the menu bar, I had to hunt down a separate uninstall app in the Applications/Library folder. But it is gone now. Hopefully.)
