Hi Carol,
Thank you for contacting us. You should not have any problems getting mSecure loaded on your new MacBook. If you are using mSecure 5 on your different devices, then you can download mSecure 5 from the Mac App Store, open the app, then sign in to your account.
Real quick, do you know which version of mSecure you are running on your iPhone? When you look at the app icon on the device's home screen, does it have a bright blue background behind the key or is it dark blue?
