Most guides on how to run Android apps on a Mac say to install BlueStacks. Since 19 October there's a second answer people are talking about: Mac.apk, an open-source compatibility layer that hit 348 points on Hacker News with the line "No emulator, no virtual machine." On 2026-10-25 I installed Mac.apk 1.0.2303 on the Mac mini M4 (16 GB) that runs this business, on macOS 26.4.1, and launched four open-source APKs from F-Droid 13 times. Three worked. The fourth, a game with native code, crashed every time. The cause is a system function that my build of macOS doesn't export, even though Mac.apk lists 26.4 as its minimum.

The Mac.apk numbers below are my own measurements. I did not run the other three routes (Mac Android Subsystem, BlueStacks Air and the Android Studio emulator), so for those I quote their own documentation.

Four ways to run Android apps on a Mac, as of 2026-10-25

RouteHow it worksStated requirementsCatch
Mac.apk 1.0.2303Reimplements Android on macOS. App code runs on a bundled Java runtimemacOS 26.4+, Apple Silicon, ~280 MB plus 1.5 to 3 times each APKAlpha. No app sandbox. Native code needs the x18 support described below
Mac Android Subsystem 0.3.4LineageOS in QEMU on Apple's Hypervisor framework, streamed to Mac windows through scrcpymacOS 15+, a quarter of your RAM (up to 6 GB), about 8 GB of diskPre-release. No Google services. 3D is software-rendered
BlueStacks AirAndroid emulator for Apple SiliconmacOS 11+, M1 to M4, 8 GB RAM (16 GB recommended), 12 GB freeProprietary, built for games
Android Studio emulatorGoogle's emulator for developers16 GB RAM, macOS 12+, 16 GB disk recommendedDeveloper tool. Several GB to download

Sources: the Mac.apk README, the Mac Android Subsystem README, BlueStacks' system specifications page (updated 2026-09-20) and Google's emulator documentation. I skipped Mac Android Subsystem on this machine. It wants a 1.5 GB Android image on first launch and a 4 GB VM on a 16 GB Mac. That would come out of the memory and disk that the always-on agent jobs on this Mac depend on.

What I ran

Mac.apk normally wants you to click Install in its window and then double-click APKs. This Mac runs without a monitor, so I used the command-line helper that ships inside the app, Contents/bin/macapk-installhelper. By default it puts each generated app in /Applications, so I pointed two environment variables from its source at a scratch folder:

export MACAPK_SYSTEM_APPS_DIR=~/work/slot-1030-android/bundles
export MACAPK_USER_APPS_DIR=~/work/slot-1030-android/bundles
H=Mac.apk.app/Contents/bin/macapk-installhelper
$H runtime-install --json          # stages ~162 MB in ~/Library/Application Support/Mac.apk
$H install --apk com.darkempire78.opencalculator_53.apk --json
open -g -n bundles/Calculator.app

Each install took 5.2 to 7.7 seconds. The apps were OpenCalc 3.2.0, Simple Solitaire Collection 3.13, Open Sudoku 4.11.3 and Shattered Pixel Dungeon 4.0.2, all downloaded straight from f-droid.org. A Python loop launched each one, sampled ps every half second for 30 seconds, then ran footprint and vmmap on the process. Each app also writes its own log with boot timings ([boot-clock] +N ms) and a check on whether the window shows real content.

Memory per Android app under Mac.apk 1.0.2303 on a Mac mini M4, macOS 26.4.1 Physical footprint and resident memory, measured 30 seconds after launch, third launch. OpenCalc: 332 MB footprint, 443.5 MB resident. Simple Solitaire: 322 MB and 434 MB. Open Sudoku: 334 MB and 447 MB. Shattered Pixel Dungeon crashed on every normal launch because Mac.apk refused to load its arm64 native libraries. footprint (footprint tool) resident set (ps RSS) 0 MB 100 MB 200 MB 300 MB 400 MB 500 MB Calculator (OpenCalc 3.2.0) 332 MB 444 MB Simple Solitaire 3.13 322 MB 434 MB Open Sudoku 4.11.3 334 MB 447 MB Shattered Pixel Dungeon 4.0.2 crashed: arm64 native code refused (x18 check)
Memory 30 seconds after launch, third launch of each app. Mac.apk 1.0.2303 on a Mac mini M4, macOS 26.4.1. Measured 2026-10-25 with footprint and ps.

Three apps worked, and each one is a JVM

OpenCalc, Solitaire and Sudoku each ran as one process. Their logs show a first frame drawn and a frame check of CONTENT or RICH, which means the window had real pixels and wasn't blank. Solitaire logged 54.4 fps and Sudoku 60. The first app launch on this Mac took 9.3 seconds to reach the app's main loop, including 3.4 seconds to start Java's desktop toolkit. After that, a new app's first launch took 1.3 to 1.7 seconds and repeat launches took 0.80 to 0.86 seconds.

Memory is where "no virtual machine" needs a footnote. A calculator used 332 MB of physical footprint and 443 MB resident, with 26 threads. vmmap found libjvm.dylib loaded in all three processes. That's a full OpenJDK 21.0.11 HotSpot runtime, 59 MB on disk inside the app. The project's own wiki says this plainly: it converts each app's DEX bytecode to Java bytecode and runs it on that bundled runtime. There's no Android system image and no Linux kernel, so it really isn't a VM in the hypervisor sense. It is a Java virtual machine, though, and that's where the 320 MB baseline per app comes from. On HN, one commenter made the same point after reading the README. For scale, in my Safari vs Chrome Mac memory usage runs, either browser with 20 tabs took about a third of this 16 GB machine. Three Android apps open at once would come to about 1 GB by footprint.

"Worked" has a caveat for Open Sudoku. On every launch, its log shows SQLiteException: prepare failed: duplicate column name: rating_level while the app creates its puzzle database. The window drew, but I couldn't see the screen to check whether any puzzles loaded. Mac.apk's compatibility list (71 apps, updated 2026-10-20) rates Open Sudoku 4.7.0 as working. I tested 4.11.3.

The native-code game crashed on macOS 26.4.1

Shattered Pixel Dungeon ships two arm64 native libraries (libGDX). It crashed on all three launches. The log says why, before the JVM's SIGSEGV report:

[x18] FATAL: x18 preservation is NOT ACTIVE on this host
  (os_set_custom_x18_abi_enabled=ABSENT (macOS < 26.4), probe=not run).
[x18]   Requires macOS 26.4+ AND the com.apple.security.custom-x18-abi-toggle entitlement.
[x18]   Refusing to load arm64 guest code.

This Mac is on 26.4, and the entitlement is in Mac.apk's signature, which I checked with codesign -d --entitlements -, the same way as in my codesign on Mac tests. So I looked for the function. In Apple's macOS 26.5 SDK, os/arch/arm64.h declares os_set_custom_x18_abi_enabled as API_AVAILABLE(macos(26.4)). On this machine, build 25E253, dyld_info -exports on libsystem_kernel lists only _os_custom_x18_abi and _os_custom_x18_abi_get. A four-line C program confirmed that dlsym returns NULL for the documented name. So on 26.4.1, the API seems to exist under a different name from the one the newer SDK documents, and Mac.apk refuses to run native code instead of risking it. That refusal is the right call, because Android's C library keeps its thread pointer in x18 and macOS clears that register.

Mac.apk offers an override, MACAPK_ALLOW_UNSAFE_X18=1. With it set, the game drew frames at 60 fps and didn't crash in 25 seconds. That shows the check is what stops the game. It doesn't make the override safe, because the developer warns it can silently corrupt memory. I can't test macOS 26.5 or later on this rig. In the project's tracker (45 issues and 55 pull requests as of today), most reports come from 26.6.2 and 27.0.x. The one other report from build 25E253 (#8) is a web-based Cordova game, which doesn't go through the native-code path. A 26.6.2 log in #43 shows Mac.apk's x18 setup running, so the path appears to work on later builds. If you're on 26.4.x and every game crashes while simple apps work, update macOS before you blame the app.

Things to know before installing it

The README says there is "no phone-style app sandbox": an APK runs as ordinary native code with your user account's permissions. Install APKs only from a source you'd trust with a Mac app. On HN, that was one of the first objections. Google Play Billing and Play Integrity don't work by design, per the Play Services page, so banking apps and apps with in-app purchases are out.

Uninstalling isn't complete either. runtime-uninstall --remove-all-apps removed the four apps but exited with status "error" and left 18 MB in ~/Library/Caches/MacApk, the logs in ~/Library/Logs/macapk and two small folders in Application Support. I deleted those by hand, unregistered the bundles from LaunchServices and checked with pgrep that nothing was still running. I added that last check after a copy of Betaflight I launched for my Betaflight on Mac test kept running for 18 hours. It mattered here: in the two crash runs I sampled, Shattered Pixel Dungeon didn't exit after its crash and sat at 61 to 72% CPU for the rest of the 30-second window.

Which one to use

For simple open-source apps on macOS 26.x, Mac.apk was the lightest route I could measure: one process, about 330 MB, under a second to relaunch, and nothing running in the background. For games with native code, check your macOS build first. If you need Google Play or a full Android environment, the VM and emulator routes run real Android but cost several gigabytes of RAM and disk. I haven't measured those routes myself. If the Mac also runs other jobs all day, budget it the way I did in how much RAM a home server needs: a 4 GB VM is a quarter of a 16 GB machine before any app opens.

FAQ

Can you run Android apps on a Mac without an emulator?

Yes, on Apple Silicon Macs running macOS 26.4 or later, using the open-source Mac.apk. It turns each APK into a Mac app and runs the app's code on a bundled Java runtime instead of booting Android. In a test on macOS 26.4.1, simple apps worked at about 330 MB each, but a game with native arm64 code crashed because a required macOS function was missing on that build.

Is Mac.apk safe to use?

Mac.apk itself is open source, signed and notarized by Apple. The apps it runs are not sandboxed: per its README, an Android app runs with your macOS user account's permissions and can read and write your files. Treat any APK like a Mac program you download, and install only from sources you trust, such as F-Droid.

Why do Android games crash in Mac.apk?

Games usually include arm64 native libraries, and Mac.apk only loads them when macOS supports Apple's custom x18 register API. If the app log in ~/Library/Logs/macapk says "x18 preservation is NOT ACTIVE on this host", that support is missing. On macOS 26.4.1 (build 25E253) the documented function is not exported. Updating macOS is the safe fix. The MACAPK_ALLOW_UNSAFE_X18 override risks memory corruption.

Method: on 2026-10-25 I installed Mac.apk 1.0.2303 from its GitHub release on a Mac mini M4 with 16 GB of RAM running macOS 26.4.1 (25E253). I installed four F-Droid APKs with the bundled install helper and launched them 13 times with open -g -n, plus one launch with the x18 override. Memory comes from footprint and ps RSS 30 seconds after launch, launch times from each app's boot-clock log lines, and the x18 finding from dyld_info, a dlsym test and the CommandLineTools 26.5 SDK header. The Mac had no display attached, so I didn't take screenshots. Whether a window showed content comes from Mac.apk's own frame check in its log. Mac Android Subsystem, BlueStacks Air and the Android Studio emulator were not installed. Their figures come from the documentation linked above. Everything Mac.apk created was removed afterwards.
