For Parental perspective:
It happens mostly parents have to buy laptop and desktop computers to their children of their choice running with different operating systems. So, they have to monitor their children's laptop activities to make sure their digital safety. Therefore, mac monitoring software enables parents to use a single license on kid’s different devices running with different OS. Parents can switch from one OS to another with the same license but they can track only one laptop device at a time. If you want to spy on all the devices of your children at the same time you have to have multiple licenses, but you can use single license one by one back and forth. So, parents can set parental control on teens and kids' computers and upload the information of several MAC laptop devices to the single dashboard. However, having multiple subscriptions you will have a separate dashboard for each license.
