Did you know that the T2 security chip offers more than just protection of your Mac computer? Learn how you can customize macOS systems with ease and make a unique and comfortable operating system with a custom startup sound you will love.
The tips in this article will work for any device with the T2 security chip, including iMac Pro, the latest iMac 2020, earlier Mac Pro 2019, Mac mini 2018, MacBook Pro 2018/newer version, MacBook Air 2018/newer model.
AIFF is a standard for audio files stored on Apple computers and devices. AIFF abbreviation means the Audio Interchange File Format, which Apple developed back in 1988.
AIFF files' extensions are .aiff and .aif. These files are not compressed like mp3, so they require more storage space on your disk.
If you are not happy with your current macOS startup sound, you can easily modify it. It is possible to add slight changes to your T2 chip system. This way, you will pick a different macOS boot chime.
By the way, all your boot chimes, also known as tones or sounds, can be found in the Mac folder:
/System/Library/PrivateFrameworks/BridgeAccessibilitySupport.framework/
Follow our guide on how to change macOS startup sound, and you will get a fun boot chime within minutes. The first thing you should do is jailbreaking. Please beware that you follow all the steps described in this guide at your own risk. While nothing should damage your Mac computer, it is still risky to interfere with the operating system code and change macOS startup sound.
Here is what you must do - launch Terminal. Now SSH into the security chip and enter the following command:
iproxy 2222 44
Get a new window in Terminal via Command + T shortcut or using this SSH command:
ssh [email protected] -p 2222
If you are asked for your root passcode, enter alpine. Apple T2 security chip files are in read-only mode by default. You can turn them into writable files with the following command:
mount -o rw,union,update /
cd /System/Library/PrivateFrameworks/BridgeAccessibilitySupport.framework/
ls -l
nvram StartupMute=%00
scp -p 2222 -r [email protected]:/System/Library/PrivateFrameworks/BridgeAccessibilitySupport.framework/ /here_enter_your_local_mac_folder/
scp -p 2222 -r [email protected]:/System/Library/PrivateFrameworks/BridgeAccessibilitySupport.framework/ /Users/checkm8/Desktop/
rm /System/Library/PrivateFrameworks/BridgeAccessibilitySupport.framework/AXEFIAudio_VoiceOver_Boot.aiff
scp -p /Users/checkm8/Desktop/AXEFIAudio_VoiceOver_Boot.aiff [email protected]:/System/Library/PrivateFrameworks/BridgeAccessibilitySupport.framework/
Afterword. If you ever reboot your computer, the default Apple startup sound will return. But you can use two commands on a jailbroken macOS gadget to turn the custom chime into a permanent boot sound (enter them after Step 6):
1) The first command looks like this:
snappy -f / -l
It will turn into a long string as the macOS snap is named. Example (com.apple.os.update-47B4872F1111CD3A9D9B6F5451673CB47C6F6F13518AF0C5FA3A0198CF1773B8E7B22D9FE42EC0C658715E10E3DFDC43)
2) The second command is like this:
snappy -f / -r “here_long_snap_string_from_command_1” --to orig-fs
It could turn into something like this:
snappy -f / -r com.apple.os.update-47B4872F1111CD3A9D9B6F5451673CB47C6F6F13518AF0C5FA3A0198CF1773B8E7B22D9FE42EC0C658715E10E3DFDC43 --to orig-fs
Now you made the boot startup chime persistent. We hope you enjoy your new custom Mac chime sound.
