Situations in which devices are replacing each other in Bitdefender Central (i.e they are not displayed simultaneously) appear when two or more systems share the same MAC address. This is only a glitch in the way Bitdefender Central displays them, with no impact on the security of the devices.
Currently, if two or more computers share the same MAC address on any network (physical or virtual), Bitdefender Central identifies them as the same device and shows only one at a time in My Devices. This is common with,virtualization software (e.g. VMware, VirtualBox, Parallels, Bootcamp, etc.) and VPN software, as they generate the same MAC address on all the devices. However, it is not restricted to these types of software.
To find out if this is the case, follow these steps below:
• On Windows devices
1. Open Command Prompt: click the Start menu, type cmd and then press the ENTER key.
2. Type ipconfig /all in the black command prompt window that appears and then hit ENTER.
3. Compare the number that appears next to Physical Address for each network in the list, on both computers.
• On macOS devices
1. Click the Finder icon in your dock.
2. Select Go.
3. Click on Utilities.
4. Double-click Terminal.
5. Type ifconfig -a in the Terminal and then press the RETURN / ENTER key.
6. Compare the number that appears next to ether for each network in the list, on both machines.
NOTE: As a workaround you can uninstall the program that generated the identical MAC address and re-install it after re-installing Bitdefender on one of the systems.
