I just received my new iMac Pro and unfortunately, I'm encountering an issue. I'm hoping someone here can help me sort it out. After powering off and back on, when I get to the login screen where you can choose which user you want to login as, the Magic Mouse and the Magic Trackpad are unresponsive. In order to highlight the Administrator account, I have to hit the left arrow twice on the keyboard to highlight the user account and then I can press Enter to get the password input box to appear. The iMac Pro is sluggish when doing those steps. After I enter the password, the iMac Pro boots normally and the mouse and trackpad work correctly after the login is complete. Here's what I've done so far to try and resolve this: 1) powered off all nearby computers and bluetooth devices near the iMac Pro 2) reset the SMC 3) reset the NVRAM None of the above has fixed this issue. I'm going to call Apple Support in an hour, but I already know how this will likely go. They will want me to the do the same steps as above and them wipe and reload the operating system. I'm really trying to avoid wiping and reloading the OS since I just spent half a day installing all of my work software on this new machine. And if I go through Apple Support and spend hours wiping and reloading everything, if the problem still exists, Apple Support will simply refer me to a "Senior Advisor" who will then have me do the same thing (and waste another half day of time) before they elevate it "the Engineering team". If I sound a little sour, it's because I am. In recent years, MacOS has presented me problem and problem and it costs me dozens of hours of precious work time. Sorry...allow me to get off the whining wagon and get back down to business. Can anyone think of any other steps to take that might fix this issue? Thanks!
