If you need to test Internet Explorer, it's often easier to use a VM on your Mac rather than using the test laptops.
- Download Virtual Box - https://www.virtualbox.org/wiki/Downloads
- Download the IE VM's - https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
- Extract the download and open the .ovf file
- Open Notepad (run as administrator)
- Open the host file → c:\windows\system32\drivers\etc\hosts
- Using NAT Network setting (default setting): Add 10.0.2.2 localhost (when using NAT network)
- Using Bridged Network setting: Add 192.168.0.* (mac ip address) localhost
- Restart the VM
- Open browser and navigate to http://localhost:8080
