Aht Mac Download

To access AHT on a computer with a Recovery Partition (including an external one—make sure it’s connected), you’ll need to press the power button to boot your Mac and then immediately press and hold the D key on your keyboard. Hold D immediately after pressing the power button. Apple Hardware Test (AHT) Description. Apple computers ship with a pre-installed suite of hardware diagnostic tools, known as Apple Hardware Test (AHT). In principle you can start them by holding the d key while booting. Newer models support holding option d to load AHT over the internet.


Apple computers ship with a pre-installed suite of hardware diagnostic tools, known as Apple Hardware Test (AHT). In principle you can start them by holding the d key while booting. Newer models support holding option d to load AHT over the internet. Refer to the official Apple documentation for details: Using AHT on Intel-based Macs, Mountain Lion, Mavericks and Yosemite. Apple redesigned the AHT, now called Apple Diagnostics, for Macs introduced after June 2013. Consult the reference codes to interpret the results.

If however, you reinstalled an older computer from scratch, the diagnostic tools might no longer be available. Unless you have the original disks that came with your computer, there seems to be no way to restore the AHT.

It happens that Apple provides disk images with AHT for most computers, but does not make the links publicly available. Various blogs and forums, mostly Riven by Five and MacForum.ro have gathered a list of download links. The rest were obtained by scraping http://download.info.apple.com/Apple_Hardware_Test/ for all the links of the form 0(18 22)-d{4}-A.dmg.

Even though there's no guarantee that this list is correct or complete, some links can come in very handy to whoever is trying to debug hardware problems.

You can use the following terminal commands to determine the model and board ID of your computer:

Download the AHT for your computer model and use the contents to restore the /System/Library/CoreServices/.diagnostics folder, then reboot while holding d to start the diagnostic tools. Alternatively you may try with a bootable USB stick, as described below.

Note that there is no one-to-one correspondence between hardware model and AHT. For some models no hardware test could be found, while others seem to have multiple AHT. As the differences are not clear, feel free to try them out, to see which one works best for your hardware.

Run AHT from bootable USB stick

  • Download the AHT for your computer model from the list below.
  • Mount the AHT dmg. Let's refer to the mount point as /Volumes/AHT.
  • Erase and mount a USB stick. Let's assume its mounted under /Volumes/USBstick.
  • Copy the AHT to the USB stick and flag it as bootable
  • Insert USB stick in the computer to be tested, boot holding the option key and select the AHT.

Unused Animations
Darling, you moved! The picture is ruined! How could you?!
Unused Models
Buckle up, because this game has a bunch of these!

Unused Cutscene

An unused cutscene that would fit well as a post-credits cutscene. This area is part of the same map that contains Hat Kid's sleeping 'The End' scene, after the credits. Changing the in-game lighting reveals that there is a rogue coat rack hiding just outside of the scene. The room design shows that this scene takes place within Mafia Town.

Unseen Area

Hidden away in the credits sequence away from the player's view is a tent with a blackboard inside like those seen in the Alpha and Beta builds of the game, it features the thank you from Mario at the end of Super Mario 64 and a few words of encouragement from W.T.N, that being William T. Nicholls, the Gears For Breakfast's art director and level designer.

Unused Cinematics

Mac Download Torrent

Unused cinematics from the Alpha trailer remain in the game. Within Mafia Town, there are four unused cinematics called cine1, cine2, cine3 and cine4. To see them, open the developer console and enter enablecheats. Then write ce <cinematic name>, and the cinematic will play.

Aht Mac Download Windows 10

In Mafia Town HQ has two strange unused cinematics called Bird and rs. The cinematic named Bird transforms you into a rat. You can move and hit Hat Kid only if you are close to her. The other cinematic is in the kitchen. When it's played, the music stops and the camera zooms onto a mafia cook working on some food. The cinematic's description calls it 'Rhythm Segment'. It might have been an introductory cutscene to a rhythm-based minigame of some sort.

Unused Music

Beta File Select

Aht Mac Download

A leftover from the Beta build of the game. It played on the title screen and file select screen.

Guard Caught Jingle

Aht Mac Download

A variation of the jingle that plays upon selecting who the murderer is in the act 'Murder on the Owl Express'. Judging by the filename, it would have played upon being caught in the stealth segment.

Hub World Secret Pillow Hideout Variation Intro

A variation of the tune that plays every time you enter Hat Kid's Spaceship. As there's never an instance where the intro plays from within the pillow fort, this variation is unused.

Sand 'n Sails Level Intro

The level introduction theme that would have played while starting the cut chapter 'Sand 'n Sails'.

Unused Text


An unused script about ties from the beta of the game.


A script for the unused cafe scene in the section above.


Standard Mafia dialogue.

Unused Diary Entries

Hat Kid's diary can be found in her bedroom by using the Ice Hat on the pile of pillows. Since both the Ice Hat and the first few Time Pieces are required to access this area, these diary entries are rendered inaccessible:

An entry for the prologue and Chapter 1, Act 1.

An entry for Chapter 1, Act 2.

An entry for Chapter 1, Act 3. Note that the words 'Time Piece' are rendered with an icon and colorization.

One more is very difficult to see in-game, because you need to save and exit from Dead Bird Studios after getting the Ice Hat then get three more Time Pieces from Time Rifts:

An entry for Chapter 1, Act 4.

An entry for Chapter 5, Act 1. The game never shows this entry due to a bug

Unused Mustache Girl Dialog

An unused cutscene in Subcon Forest featuring Mustache Girl and Snatcher.

Unused Graphics

A collectible birb. It can no longer be collected.

Menu icons for collected and uncollected Time Pieces. These originated from the Alpha build.

UI relating to 'Badge Points', a function removed for the final game. Badge Points were only available in the Alpha and Beta builds.

A texture for the now-removed Electro Badge. This badge appeared in pre-release builds of the game.

A badge that went unused for the Ice mechanic. Being eventually replaced with the 'Ice Hat' in the final game. It was formally known as the 'Ice Statue Badge'.

An early badge referred to as the 'Owl's Brew Badge'. It was eventually replaced with the 'Brewing Hat' in the final game.

An unused UI image for Hover Yarn. The hover functionality was modified and delegated to a badge instead of a hat.

A placeholder UI icon for a water flask, using its 3D model. The water flask was not used for the final game, and was likely related to the 'Sand 'n Sails' chapter before that chapter was turned into 'Alpine Skyline'.


A placeholder UI icon for the Dweller's Mask, using its 3D model.

A concept design of the game's title screen.

An additional concept design visualizing object paths. It contains some notes in yellow that are too small to read.

A watermark leftover from the previous speedrun event build.

Prototype/Alpha Build Graphics

To do:
Detail exactly which builds this content is found in. If it's not final, it goes on one of our lovely prototype pages.

Graphics found within the Alpha build of the game. Features leftover assets from the Prototype build.

UI originally used in the act: 'Barrel Battle'. It was modified in the Beta build of the game and removed completely in the final.

Pretty self explanatory. Early UI for the Badge menu.

A collection of leftover icons and logos used in the prototype build.
