YOUR FIRST GAME
Set up S2Arm to play on your Mac
Prepare an Apple silicon Mac, import your own game and keys, build for macOS and verify your first playable scene.
You confirm each step yourself. We cannot detect your device or game. Skipping does not count as completion.

Build and play on the same Apple silicon Mac. You do not need an iPhone connection or phone signing for this route. Check your files and device first.
STEP 1 OF 5
Step 1: Install and open S2Arm
Get S2Arm-mac-arm64.dmg from the official v0.2.8 release, follow the disk image's installation instructions and open S2Arm from Applications. The baseline app declares macOS 15 or later; the build toolchain has separate requirements. Read the release notes if choosing a later version.
Success check: The launcher shows computer preparation, keys and Add Game.
STEP 2 OF 5
Step 2: Prepare the Mac build environment
Follow the environment check to install full Xcode, open it once for initial setup, prepare Metal components and check again. Do not add phone-signing accounts or iOS components solely for phone installation when only playing on Mac. Follow any specific build dependency reported by the check.
Choose a local APFS game library with enough room, outside cloud sync folders. Originals may remain elsewhere; keep external storage connected. See storage and disks.
Success check: The Mac build requirements pass. If your macOS cannot run the required Xcode, resolve that compatibility issue before continuing.
STEP 3 OF 5
Step 3: Import your keys and game
Select your own prod.keys, then Add Game. Choose the base NSP/XCI or a folder containing the base and its updates / DLC. Allow access to the selected folder when required.
Check the game name, version and missing-item notices after reading finishes. Use import troubleshooting for file, permission and keys errors.
Success check: The game appears in the library with required inputs present.
STEP 4 OF 5
Step 4: Build for macOS
Select the game, open the build page and choose macOS. Process only this game for the first run. Keep power and storage connected until the task finishes.
Success check: The build succeeds and offers a launch action, without an unresolved failure. Check update and rebuild guidance for zero-precompilation or other warnings. Build completion does not establish that the entire game has been tested.
STEP 5 OF 5
Step 5: Launch from the library
Return to the library, select the game and launch it there. Do not move only the output app: runtime resources may remain elsewhere in the library. Official installation guide
Reach an interactive scene and try the keyboard or controller. If only the controller fails, use controller troubleshooting. For a crash or black screen, record the scene and prepare a report.
v0.2.8 fixes missing graphics functions used by some OpenGL games. If upgrading because of a launch crash, follow the update and runtime checks and retry the same scene. This is not a general game-compatibility or performance guarantee.
Success check: You reach a playable scene and confirm input. Continue to after your first game.
