Android Emulator Settings on Mac: What Each of the Seven Cards Does

The Settings of the MACOS EMULATOR launcher open with the gear icon, at the top right of the home screen. No sidebar: seven stacked cards that you scroll through, with “Done” always visible at the bottom. In order: Subscription, Device, Performance, Beta settings, Application, Engine and storage, Uninstall. Here is what each one holds, and what restarts the device.

First: most values are already the right ones

The launcher sets up the device based on your Mac’s memory: the memory given to Android, the quality and the refresh rate. The guide says it plainly: the default values are the right ones. Settings are mostly there for the day something goes wrong.

What powers off the device, and what waits for the next start

• Graphics, Resolution and Refresh rate, on the Device card, carry the note “(restarts the device)”. If the device is running, the launcher powers it off, and the next start is a cold one, so a longer one.
• A Machine profile button, or “Mine”, can power it off too: if the device is running and the click changes the resolution or the refresh rate.
• Processor and Memory power nothing off, but only count at the next cold start, as the note under these two rows says.
• Retina game window, on the Beta settings card, applies at the next start of the device.
• Everything else applies at once: the device’s form factor, Performance mode, the language of the launcher’s windows.

So change the Device card between two matches, never in the middle of one.

Subscription

At the top, the state of your license, for example “Active subscription.”, lifetime license included. With an active subscription, two buttons: “Manage” opens your customer area, “Sign out” removes the key from this Mac, and nothing more. Without an active subscription, they give way to “Subscribe”, and to “Re-check” if a key is already saved: that is the one to use after more than 72 hours offline. See the license key guide and, to move from one Mac to another, the guide to switching Macs.

Device: the heart of the settings

The largest card, in three groups separated by a line.

• Form factor (instant): Phone or Tablet (iPad-like). The change applies without a restart, and your account and your games stay intact.
• Graphics: two choices. Keep the one the launcher picked, unless support asks you to change it.
• Machine profile: one button per class of Mac, 8 GB, 16 GB and 24 GB +, with your Mac’s one written in orange. One click restores the class’s memory, resolution, quality and refresh rate in one go, at the next start (if it changes the resolution or the refresh rate, it powers off a running device); the cores do not move. “Mine” brings back the values you had before your first click.
• Resolution: Fluid (1440x900), Sharper, Sharpest and Screen, subtitled “fullscreen sharp”. The orange (?) next to it works out the blur for your display, and the guide to full screen in an emulator says which one to choose.
• Refresh rate: 60 Hz or “30 Hz, steady”, with your class’s value marked “(default)”. The guide to an emulator’s graphics explains what it changes.
• Processor and Memory: the cores and the memory given to Android. Memory moves in half-gigabyte steps, and the note underneath gives your Mac’s ceiling. The launcher picks 4.5 GB on 8 GB, 6.5 GB from 16 GB and 10.5 GB from 24 GB: only touch it last, after reading the guide to an emulator’s memory.

Performance: leave it as it is

The guide files this card among the advanced switches: leave them as they are, unless support asks you otherwise. The rows that matter:

• Performance mode, with its lightning bolt: on by default, it puts the game ahead of the rest of the Mac while you play, and applies at once. The Performance mode guide gives the only case where you should turn it off.
• Screen resolution: the row only appears if your display is set to “More Space” in macOS, with an “Open Displays settings” button. “Default” costs the Mac less.
• Keep the device ready: leave it as it is, unless support asks.
• Report: “Copy” measures for six seconds and copies a performance report. Take it from the toolbar instead, in the middle of a match: the guide to measuring FPS in an emulator explains why Settings skew the measurement.

Beta settings

A single row so far: “Retina game window”, off by default and applied at the next start of the device. Same advice as for Performance: leave it as it is, unless support asks you otherwise.

Application: the language

The Language row offers Auto, English, Français and Tiếng Việt. Auto follows your Mac’s language. The guide to the emulator’s languages says what Android takes from this choice.

Engine and storage

• Engine: the installed version. An “Update to” button, followed by a number, only appears if a newer version is offered; power off the device first, the launcher asks you to.
• Logs, “View…”: the logs to copy for support, detailed in the guide to the emulator’s logs.
• Disk, “Free up space”: removes the Android systems no device uses and leftover downloads, and may find nothing. The guide to an emulator’s disk space says what the rest weighs.
• Folder, “Show in Finder”: opens the emulator’s folder, whose path is shown just below. Do not delete anything in it by hand.

Uninstall

At the very bottom, “Uninstall…” opens a confirmation. “Uninstall and quit” erases the engine, the Android data, the installed games, your key mapping and, in Full mode, your Google session on the device, then moves the app to the Trash. It cannot be undone, but your license key stays valid. Copy your logs first: the guide to uninstalling an Android emulator details the rest.
