I ues the latest Apple OS and can not log onto Studio. When I try it simply hangs and I get the spinning wheel. When I dowloaded Studio about a week agoe it worked fine. I could log-on directly, or go through Photoshop or Lightroom. In Photoshop both Studio and Studio- clarity appear in the menu, but it hangs when I try to log-on. I removed Studio and downloaded it again, but that did not help. I know that my username, email (tried both) are correct, as is my password. In fact, when I intentionally put them in incorrectly I get a message that my username or password is incorrect. . When I put them in correctly it tries to log-on and I get the spinning wheel.
