Emulator: Warning: Quick Boot / Snapshots not supported on this machine

I am starting to learn android but havent been able to get anywhere. I downloaded android studio as per instructions and im trying to set up an AVD.
I am using a Mac Air(macOS High Sierra) with java 1.8.0_51.

The moment i launch an AVD there is a warning in the event log:
"Emulator: Warning: Quick Boot / Snapshots not supported on this machine. A CPU with EPT + UG features is currently needed. We will address this in a future release."

The emulator just gets stuck on the loading page.

So far i have tried to :
1. Reduce AVD Ram size
2. Increase AVD heap size
3. change to "software" to avoid issues if any with my graphics card
4. Install/ delete many versions of phones/api levels for avd

In the Logcat logs i see the following errors:

03-09 17:27:15.544 0-1114/? I/lowmemorykiller: No kernel
memory.pressure_level support (errno=2) 03-09 17:27:15.545 0-1114/?

I was suffering from same problem. I searched everywhere but i didn't get the solution. Then i knew that this problem is occurring only because of low RAM.

You can solve this problem by increasing the RAM. Because my laptop had 4 GB RAM and when the RAM increased the problem solved completely! Although i bought a new laptop with i5 8th gen.. It have 8gb RAM...

better and faster than AVD you can use your android phone, when you connect it to your computer through usb, android studio can recognize it and install your apk on your phone faster.
