Here's a tip to J801 users on recent versions of Mac OS X about a feature/annoyance of that system.
If you have set your OS X System Preferences > Security & Privacy > General to allow only apps downloaded from Mac App Store, or from Mac App Store and identified developers, then without special steps you will be unable to run jcon801.app, jqt801.app, or jhs801.app. As usual with such security settings, you will get the pop-up saying the app is from and unidentified developer and cannot be run. With most such apps in this situation, there's an easy one-time workaround: Ctrl-click the app, from the context menu that appears pick open, and then in the new pop-up dialog with its warning again about the unidentified developer, click the Open button. That doesn't work with jcon801.app, jqt801.app, or jhs801.app, as you will not get that choice of an Open button after doing the preceding. Instead, there's a slightly more complicated one-time workaround: - open System Preferences > Security & Privacy > General - at the bottom of that window, you'll see a place you can click to allow the specific app to open. If the Security & Privacy preferences are locked, you may or may not need to click the lock icon and give a password to unlock it before doing the preceding. I'm not sure: by habit, I unlocked it before allowing jcon801.app to open, then locket it again. But when I used the same procedure for jqt801.app, I didn't need to unlock the preferences again.
