This bash script checks the Hardware Model, Board ID and returns the download link of the AHT dmg file you can use to diagnose your Mac.
Apple Hardware Test (AHT) was an often built in diagnostic tool used to detect problems with your Mac system. Apple changed to another Diagnostic system starting with Macs released in June 2013. This means that the script will not find a download for newer Macs as they do not support AHT. This is a great tool however to find the right link for your older Mac.
Some Mac models have a server version. Please contribute if you have a server by testing all download codes you get presented and mentioning which ones do and don't work so the script can be updated accordingly. Eg. The Mac mini 4,1 has both a server and a non-server model. But they have different versions of AHT. I will personally test as many models of Mac as possible, but i don't have access to most server models. Any help would be appreciated!
There are 2 methods to use this tool. A little bit of command line knowledge will be handy though.
Download the latest release and unpack it. Double click the installer and follow the steps to install it. After install, open Terminal and enter /Applications/AHTFinder/AHTFinder.sh
Now, use the tool however you want.
Download the latest release, unzip it and open Terminal. Navigate to the directory of AHTFinder.sh (Make sure osx-cpu-temp and AHTFinder.sh are in the same folder)
Next, run AHTFinder.sh with ./AHTFinder.sh
Now, use the tool however you want.
Choose a USB drive with at least 512mb (recommended).
Warning: During the following process all data on this drive will be erased! If you need the data on it, make a backup first.
I will not be liable for any loss of data
Use Disk Utility to erase the usb drive. Make sure to format it as Mac OS Journaled with the GUID Partition Table
Take your .dmg file and double-click it to mount it. If you have an older Mac, you might get a message saying that this 'legacy image should be converted'. If so, check a little lower for a guide.
Let's assume your usb drive is called 'Untitled'. This means that the mount point is /Volumes/Untitled. But this might differ. If you are unsure, unmount and disconnect all other storage drives except for your diagnostics drive. The mount point would be /Volumes/{YourDrive}.
Let's assume your .dmg file is mounted in /Volumes/AHT (Your image would be mounted in /Volumes/{yourDMG})
Open Terminal and type the following command:
cp -r /Volumes/{yourDMG}/System /Volumes/{YourDrive}This copies the system folder of the image to the usb drive. Fill in the parts between '{}' for your usecase. (don't just copy/paste this line)
To make the USB drive bootable, enter the following command
sudo bless --folder /Volumes/{YourDrive}/ --file /Volumes/{YourDrive}/System/Library/CoreServices/.diagnostics/diags.efi --label AHTYou might need to enter your password to authenticate.
After this, you can safely close all windows. Eject the USB drive and plug it in the computer you want to test.
Shut down the computer to test, press the power button and immediately hold down the ALT/Option key. When you see a boot menu, select the drive that is either called AHT or EFI Boot (or something similar).
You have now succesfully started the diagnostic tool. Congratulations!
Open Disk Utility and click on the Convert button. Select the image, rename it (add something like 'converted') and click on save. Now continue the process with the newly converted image
Please notify me by opening an issue if you find something that's wrong. Is the wrong model shown? Is a link not/no longer working? Please report it. Be sure to mention the Hardware Model and Board ID and if the wrong one is mentioned also what the wrong model is. This way, fixing bugs is much easier.
If you do end up using this, please also open an issue mentioning your test results so i can update the tested and verified column. Open an issue with title: verification or something like that, mention the used download code, Board ID and Hardware Model. Thank you in advance!
