Dell Inspiron 14 7472, MacBookPro15,2, etc. --> * (Optional) Host computer model: **Guest Environment** <!-- Complete this section if you are trying to run Android Emulator or QEMU with HAXM acceleration. --> <!-- E.g. Android Emulator 28.0.20, QEMU 3.1.0, etc. --> * Android Emulator or QEMU version: <!-- E.g. Ubuntu 18.04.

Install/Upgrade to HAXM v7.8.0 2. Start Android Emulator for any AVD 3. Android Emulator hangs at `Connecting to Emulator` **Expected Behavior** <!-- A clear and concise description of what you expected to happen. --> Expectation: Android Emulator should start **Reproducibility** <!-- The probability of getting the issue reproduced after following the above steps, e.g. 100%, 50%, etc. --> **Diagnostic Information** <!-- If you get a host crash, i.e. Windows Blue Screen of Death (BSOD) or macOS kernel panic, provide the crash dump (by attaching it to this GitHub issue or sharing it with us in private).
