Installation

Requirements

• A Mac with Apple Silicon (M1 or newer).
• macOS 13 or newer. macOS 15 or newer is recommended: it lets the game keep its GPU memory resident, which is faster.
• Your own decrypted dump of Bloodborne with the 1.09 update. See Game files.

Nothing else is needed: the app includes everything it uses to run the game.

Install

1. Download the latest DMG from the Releases page (bloodborne_mac-<version>-arm64.dmg).
2. Open the DMG and drag Bloodborne to Applications.
3. Open Bloodborne from Applications.

The first time you open it

The app is not signed with an Apple Developer ID, so macOS blocks the first launch. To allow it:

• right-click (or Control-click) Bloodborne in Applications, choose Open, then Open again; or
• open it once, then go to System Settings → Privacy & Security and choose Open Anyway.

macOS remembers the choice. You only need to do this once per version.

First start

1. On the Home tab, choose your game folder (the folder that holds eboot.bin and sce_sys).
2. The launcher checks the folder and shows the game's edition, region and version. If something is wrong, it tells you what and how to fix it. See Game files.
3. Press Play.

The first start compiles the game's shaders and takes a few minutes. Later starts are faster. After an update that changes the shader cache format, the shaders are compiled again.

Where your data lives

Everything the app writes is kept in ~/Library/Application Support/bloodborne_mac:

Path	Contents
launcher.db	Your profiles, settings, backup records and trophies
user/, save-profiles/	Saves, and the shader cache
save-backups/	Backups of your saves
bbport.ini, launcher.json	Copies of the settings for the game's scripts
mods/, patches/	Mods and third-party patches
logs/last.log	The log of the last run

The game folder is never modified.

Updating

Download the new DMG and replace the app in Applications. Your saves and settings stay in the data folder above. The launcher tells you when a new version is out (Updates).

Uninstalling

Delete Bloodborne from Applications. To remove your saves and settings too, delete ~/Library/Application Support/bloodborne_mac.
