The classic sequence of Macintosh startup includes startup reads, Happy Mac, Sad Mac, and Chimes of Death. This has all been done with time, and the release of the MacBook Pro 2016 eliminates the remaining startup features: startup blends, supports a more discrete sequence with a black background and no audible indicators, despite its use as a security feature that provides friendly verification user and it can be heard that the computer's NVRAM configuration is authentic. Apple added a startup rattle back for the 2017 MacBook Air release.

Startup chime
The Macintosh startup casing is a single chord known as "startup sound". The sounds used differ depending on the ROM, which varies greatly depending on the model type. This short voice is played when the Apple Macintosh computer is turned on. Sound indicates that a diagnostic test run immediately at startup does not find any basic hardware or software problems.
Mark Lentczner codes for arpeggiated chords used on Macintosh II. This voice variation is used until Jim Reekes creates startup used for Quadra 700 via Quadra 800. Reekes says, "The startup sound is done in my home studio at Korg Wavestation EX.This is the C major chord, played with both hands stretched as wide as possible (with 3 at the top, if I remember.) "He is also the creator of the icon (or" earconic ", as he calls it)" bong "startup used on most Macintosh since Quadra 840AV. The slightly lower tone version of this bell is used on all PCI-based Power Macs up to iMac G3. Macintosh LC, LC II, and Macintosh Classic II do not use the Reekes symbol, but use the F major chords that only produce "ding" sounds. The first generation of Power Macintosh computers also did not use chime reekes, but instead used a chord picked on a 12-string Yamaha acoustic guitar by jazz guitarist Stanley Jordan. Furthermore, the Power Macintosh 5200-6300 computers (excluding 5400 and 5500, which have "bong" chime) use unique bells, and 20th Anniversary Macintosh using other unique sounds.
For models made prior to the introduction of the Power Macintosh in 1994, the Sad Mac icon, error codes, and distinctive sounds, were shown in the failure of the initial diagnostic diagnostic test. This phenomenon is called the "Death Bell".
The bells for all Mac computers since 1999 are the same bells used first in the iMac G3. The chord is the F-sharp major chord, and is produced with a pitch-shifting sound of 840AV. Mac startup chime is now a registered trademark in the United States, and is featured in the 2008 WALL-E movie when the titular robot character is fully charged by solar panels as well as in 2007 Brad Paisley's song "Online."
Starting in 2016, Apple has removed startup starting with the end of 2016 MacBook Pro. Apple has since updated the support documentation to reflect this change, removing references to startup reads from the NVRAM reset instruction for this model.

Happy Mac
A Happy Mac is a normal bootup (startup) icon of an Apple Macintosh computer running an older version of the Mac operating system. It was designed by Susan Kare in the 1980s, drawing inspiration from the Compact Macintosh series design and from the Batman Two-Face character. The icon remains unchanged until the introduction of New World ROM Macs, when it's updated to 8-bit colors. Mac Happy indicates that booting has started successfully, while Mac Sad (along with a melody of "Chimes of Death" or one or more beeps) indicates a hardware problem.
When the Macintosh boots into Mac OS 9 or lower, the system will play startup, the screen will turn gray, and the Happy Mac icon will appear, followed by a Mac OS splash screen (or a "Welcome to Macintosh" screen in System 7.5 and earlier), which underwent some stylistic changes. Mac OS version 8.6 and later also includes the version number on this splash screen (for example, "Welcome to Mac OS 8.6").
On an early Mac that did not have an internal hard drive, the computer booted up to the point where it needed to load the operating system from the floppy disk. Until the user enters the correct disk, Mac displays a floppy icon with a flickering question mark. On the next Mac, a folder icon with a question mark that repeatedly changes to the Finder icon is displayed if the System Folder or boot loader file can not be found on the startup disk.
With the introduction of Mac OS X, in addition to the flashing system folder icon, a banning icon was added to indicate an incorrect OS version was found. The bomb screens were replaced by a panic kernel, which was originally white but turned black in version 10.3. With Mac OS X 10.1, a new Happy Mac is included. This is also the last version that has the Happy Mac icon; in version 10.2, Happy Mac symbol replaced with Apple logo.
The Face ID logo for iPhone X is based on Happy Mac.
Mac Sad
Sad Mac is a symbol used by old-generation Apple Macintosh computers (hardware that uses the Old World ROM instead of Open Firmware, which is preceding USB onboard), starting with the original Macintosh 128K and ending with the latest NuBus Macintosh Power model (including generation first 6100, 7100, 8100, and PowerBook 5300 and 1400), to indicate a severe hardware or software problem that prevented the startup from succeeding. The Sad Mac icon is displayed, along with a set of hexadecimal codes that indicate the type of problem at startup. Different codes for different errors. This is used instead of the normal Happy Mac icon, which indicates that the startup-time hardware test is successful. In the 68k model made after the Macintosh II, Chimes of Death is played.
The model before the Macintosh II was crippled silently and featured Mac Sad, without any notes. PowerPC Mac plays sound effects from car crashes, and computers equipped with PowerPC update cards use three fanfare death chime (A, E-natural, and E-flat) ring tones just like Macintosh Performance 6200 and Macintosh Performance 6300.
The Sad Mac may be deliberately created at startup by pressing the interrupt button on an installed Macintosh computer, or by pressing Command and Power buttons shortly after startup sounds. On some Macintosh like the PowerBook 540c, if the user presses the command and the power button before the boot screen is displayed, it will play "death knell". The bells are a fraction of normal speed and no Sad Mac is displayed.
Model World ROM Power Macintosh and PowerBook based on PCI architecture do not use Sad Mac icon and will only play error/car-crash sound on hardware failure (such as missing or bad memory, unusable CPU, or similar).
Mac OS X 10.2 and later use the Universal "no" symbol to indicate hardware or software errors that make the computer unbootable.
iPod Sad
On iPod, if any damage or error occurs on hardware or firmware, for example, if the file is deleted, it appears Sad iPod . It's similar to Mac Sad, but instead of a Macintosh, there's an iPod, and no death knell. The icon also has no nose, and the scowl is turned horizontally. It also does not show hexadecimal codes that indicate what issues are happening on the iPod. This error screen will not appear when the problem occurs on newer iPods.
Death bell
The Chimes of Death is a Macintosh equivalent of a beep code on IBM PC compatibles. On all Macintosh models that precede the adoption of PCI and OpenFirmware, Chimes of Death is often accompanied by a Sad Mac icon in the center of the screen.
Different Macintosh series use different death bells. Macintosh II was the first to use death knell (big arpeggio up, with different bells on many models). Macintosh Quadra, Centris, Performance, LC and Macintosh Classic play the main arpeggio up, followed by three or four notes, with slight variations depending on the Macintosh model. Macintosh Quadra AV660 and Centris AV660 use a Roland D-50 "Digital Native Dance" sample sound, while NuBus-based Power Macintosh models (including 6100, 7100, and 8100) use car crashes. Power Macintosh and Performance 6200 and 6300 series, along with Power Upgrade Macintosh cards, use a dramatic 3-note brass sound with drum rhythms and cymbals. PowerBook 5300, 190, and 1400 use the second half of the 8-note arpeggio as found on the Quadra and Centris models, or the entire death blends if an error occurs before the screen turns on. Pre-G3 PCI Power Macs, Beige G3 Power Macs, G3 All-In-One, and PowerBook 2400, 3400 and G3 all use a stirring noise in windows, making it sound like the computer accepts startup errors by destroying windows; these models do not display the Sad Mac icon. Since the introduction of the iMac in 1998, Death Bell has ceased to be used and replaced with a series of tones to indicate hardware errors.
