"To avoid problems this is my short list:
Do not use the AppStore version. Period, I don‘t discuss this. The AppStore version is the same software, but is executed in a sandbox. It creates problems, especially in all interactions with the OS.
If using the direct install from the website, and there are problems like not starting, or permanently high CPU usage, log out (if possible) and make a full uninstall using AppCleaner. Then restart the Mac, and install again from the EN website. Open, log in. Now let the app run in the background (or use it, doesn‘t matter) for quite a while to allow it to download the database again from the server.
In the usual updating process I don‘t have problems. If an update is offered by the app, I update. If I know there is an update (solving an issue), i simply get the installer from the website and install it on top of the existing install."
