New problem: the 'mouse' on my iPad will not activate anything. I can move the mouse but left or right 'clicking' does nothing. Any ideas? Re: Invalid Email Format - Catalina OS Thank you for the login fix, which now works for me. However, when loging in to my Mac from an iPad, the iPad shows a blank desktop with no access to the dock or any apps. I can access files remotely, but can't get to or run any apps on the remote Mac. Does anyone else have this problem? Re: Invalid Email Format - Catalina OS I am having the same issue as everyone else on this thread. I did a full uninstall using the Terminal command "sudo /Library/Application\ Support/LogMeIn/uninstaller.sh" restartedand then did a full re-install. I try to login and get the "Invalid Email Format" error. macOS Catalina 10.15.1
