In order to re-enable the kext security protection, you need to restart your Mac in Recovery OS, open a Terminal window and run csrutil enable. To be sure it works, you can also run sudo kextload -bundle-id. silent_install.sh and that should be it. Save the file and open a Terminal at this location. You need to add the 10.13 version after 10.12 (separated by space, just like the rest). You will find it on the line which should look like this for v in 10.8 10.9 10.10 10.11 10.12 Unzip if needed, edit the silent_install.sh file and search for the 10.12 OS version. Then restart your Mac and log in, go here to download the latest Intel HAXM driver. Next, you need to go to Utilities > Terminal and run: csrutil enable -without kext This command will only work on Recovery OS, which means that you need to restart your Mac and hold command + R until the Apple logo is displayed. Essentially you need to disable the security protection on kext before trying to install the HAXM drivers. There might be other (better) solutions to this, but I have successfully managed to start the emulator this way. I was able to install Intel HAXM drivers on my Mac using the instructions provided in this post. If you have already installed the latest Intel HAXM Manager (v6.2.1) then re-install it and restart your computer. Try using Hypervisor.Framework as mentioned in this post. It says: HAXM silent installation only supports macOS from 10.8 to 10.12 ! Is there any way of using Android emulator on High Sierra (10.13)?
