When I install WD Security (v 22.214.171.124) it adds WDSecurityHelper to my login items on my late 2013 Mac Pro. After installation, each time I start my Mac it freezes for 6 (!) minutes immediately after I boot the Mac (the system log file shows absolutely no activity and the screen shows only the Apple logo and a spinning wheel for exactly 6 mins). When I remove WD Security and restart twice the problem is gone.
Anyone else seen this problem? I’m running Mavericks 10.9.4 and I have attached a WD MyPassport Ultra.
