Hello community,

Id like to run an Internet AHT (no DVD with me)on my mid-2010 MacBook Pro but this message always appears:

apple.com/support -3403D.

Anyone knows about this error?

Thanks for your help

Try booting the MBP with the OPTION+D keys. It may work.

If you had the original install DVDs, you would not have this problem. Duplicates can be obtained from Apple Customer service.

Ciao.

This is the same message that I received . My Thunderbolt port doesn’t work and I did test system for that reason.

Same here. MacBook Pro mid-2010. Having problems since Yosemite install a month or two ago. Nothing happens when I try to boot holding down the d key. The system just sits until I release the d key, at which time it reboots in normal mode. Option-d causes the error everyone else is getting here.

To use the internet for the apple hardware test, your Mac had to ship with at least Lion. Otherwise you have to have the install dvd that came with the Mac. Not a retail version, but the machine specific software. https://support.apple.com/en-us/HT201257

This is straight from someone at Apple, «That -3403D code actually means there was an issue with your Mac software configuration«

Feb 4, 2016 10:29 PM in response to Mammadmo

To all that get that code. It means your Mac cannot do the hardware test from the internet. You need the install disk that has the hardware test on it. Then you boot it and hold down D or Command D at startup.

Very strange i am having the same today? Coincidence?! I am trying internet recovery….

Feb 5, 2016 8:38 AM in response to tsja22

my ginger’s solution is what worked for me. I can’t do internet recovery on my mac—it’s a bit too old. I used the dvd that came with the mac and that worked fine. Showed no hardware errors, but worked. The overall problem I was having was with the video card. Got that replaced and I’m back in business.

Feb 26, 2016 2:46 AM in response to MILLETT117

I first also had trouble. Funny thing was that with the power connected the led in the connector near the laptop was not green or range but not doing anything. Then I disconnected the connector to the white square block (with power still connected) and the led was again green. Very strange! Then the laptop booted and I could do the restore process (Created bootable El Capitan USB / Installed fresh version of El Capitan / Restored data with Time Machine ).

While this may be true, it is odd that the machine appears to attempt to load the hardware test (it goes through all the correct motions before bringing us to the -3404D error). Further, why not simply give a message like, «Sorry, hardware test via the internet is not supported on this Mac,» rather than some unhelpful, cryptic message?

Finally, determining if your computer supports loading Apple Hardware Diagnostics over the internet isn’t necessarily easy to do using the info from Apple. Quoted from their webpage, «Some Macintosh computers that shipped with OS X Lion and later support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT.«

Some? How helpful is that? Why don’t we throw in «may» and «possibly» and how about «we don’t really know» for good measure.

I have an early 2011 MBP 13 that does do the AHT over the internet, and a Mid 2010 that doesn’t, so for the 13s that appears to be the cutoff. How hard was that, Apple? FFS

Mar 2, 2016 8:57 AM in response to Hotchili

2010 and older Mac’s that run Snow Leopard or older. Have to use the install disk for AHT. Some 2011 or newer with a smc and efi update can run the online diagnostics. Usually the update is part of a software update. If you have the original install disks, you don’t need internet diagnostics. This is because after Snow Leopard, all operating systems came by way of a download from apple, if not preinstalled. The reinstall and the utilities is on line. The early 2011 that came with Snow Leopard generally can’t use the online diagnostics. As a general rule. If your computer came with Lion or newer, you use the online diagnostics.

Jun 5, 2017 12:41 AM in response to my ginger

HI, I do have the original install disks for my iMac 27-mid 2010 but even so always get the same error message mentioned on this thread (3403D) when I try to run the ADT.

Sep 27, 2017 6:14 AM in response to ghjorazz

I have it too. Using an old (around 2010) and now problematic iMac.

https://support.apple.com/en-us/HT201257

I think in my case, and maybe yours too, this paragraph pertains:

If you’re using OS X Lion v10.7 or earlier and you can’t get AHT to start, see if you have an OS X installation disc named “Applications Install Disc 2.” Insert the disc in your internal optical drive or external Apple SuperDrive before following the steps above. Or, if you’re using a MacBook Air (Late 2010), plug the MacBook Air Software Reinstall thumb drive into your USB port instead.

The problem with my iMac is that the internal optical drive broke very early after purchasing this iMac. Actually it broke in (or around) an earthquake back in 2011 It just won’t swallow any optical disc since.

Apple HW Test error code -3403d

pvlucasz

macrumors newbie

I’m currently trying to run an apple hardware test on a mid 2010 21.5″ iMac running osX Mavericks as the iMac is running very slowly so I suspect a HDD failure is imminent.. Upon pressing (option + D) on start-up i’m greated by the image of a globe with it trying to connect and download. then being displayed with the error code -3403d. I have already searched the forums for this error and no one has gotten a reply, so I thought i’d start a new thread and get it to the top of list. I have made sure i am connected to my network, i am using an ethernet cable to do this. I can boot into recovery mode with (command + option + R). I have tried running first aid on both the HDD itself and the partition that MacOS is installed on.

Any help would be greatly appreciated.

I think that error code means that AHT can’t be located. You need to run AHT from the 10.6 Applications Install Disc 2 that came with your iMac.
Here are some instructions:
https://support.apple.com/en-us/HT201257
Here are some step from the above link:
Using Apple Hardware Test on computers with OS X v10.7 and earlier:
1. To start AHT on these computers make sure the Applications Install Disc 2 is inserted into the built-in optical drive

2. Shut down your computer. Then, press the power button to turn it back on.

3. Press and hold the D key before the gray startup screen appears.

4. It takes a minute or so for AHT to start up and inspect your hardware configuration.

5. When the process is complete, select your language and click the right arrow. If you aren’t using a mouse, you can use the up and down arrows to select a language and then press the Return key.

6. The AHT console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the «T» key or the Return key.
To perform a more thorough diagnostic test, select the «Perform extended testing» checkbox under the Test button before you click the Test button.
Note: Your test results will appear in the window in the bottom-right of the console.

7. To exit AHT, click Restart or Shut Down at the bottom of the window.

Question: Q: Error code 3403D on iMac

iMac 21.5″ Mid-2010 Model 11,2 3.06 GHz Intel Core i3 Yosemite 10.10.5

This thing has been a terrific workhorse for nearly 7 years. Only thing I’ve had done was a new power supply in 2013.

It’s freezing intermittently — I can move the cursor but that’s all — it doesn’t activate anything. I have to restart.

So I tried to run AHT but it won’t run. Tried to run it from the internet (Command D) but again no luck — except this time it gave me that error message. Does anybody know what it means? And what I should do about it — and about the freezing?

Hi,

I’m currently trying to run an apple hardware test on a mid 2010 21.5″ iMac running osX Mavericks as the iMac is running very slowly so I suspect a HDD failure is imminent..

I have already searched the forums for this error and no one has gotten a reply, so I thought i’d start a new thread and get it to the top of list. I have made sure i am connected to my network, i am using an ethernet cable to do this. I can boot into recovery mode with (command + option + R).

I think that error code means that AHT can’t be located. You need to run AHT from the 10.6 Applications Install Disc 2 that came with your iMac.
Here are some instructions:
https://support.apple.com/en-us/HT201257
Here are some step from the above link:
Using Apple Hardware Test on computers with OS X v10.7 and earlier:
1. To start AHT on these computers make sure the Applications Install Disc 2 is inserted into the built-in optical drive

2. Shut down your computer. Then, press the power button to turn it back on.

3. Press and hold the D key before the gray startup screen appears.

4. It takes a minute or so for AHT to start up and inspect your hardware configuration.

5. When the process is complete, select your language and click the right arrow. If you aren’t using a mouse, you can use the up and down arrows to select a language and then press the Return key.

6. The AHT console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the «T» key or the Return key.
To perform a more thorough diagnostic test, select the «Perform extended testing» checkbox under the Test button before you click the Test button.
Note: Your test results will appear in the window in the bottom-right of the console.

7. To exit AHT, click Restart or Shut Down at the bottom of the window.

Hi Coastal,

Thanks for your prompt reply. Unfortuantely for me I no longer have the discs that came with the iMac. Is there anywhere i can download the discs or a copy of the Apple Hardware test that can be ran standalone? I’m not sure if this exists. If worst comes to worst I’ll have to flatten and reinstall. It’s just annoying as I think there maybe an underlying issue with the hardware. I’m experciancing some serious stability issues. I have other diagnostics software for normal PC’s but unfortunately it doesn’t run on Mac’s.

Any further help would be greatly appreciated.

Well, I understand AHT can be downloaded from github. I have not done this or downloaded from them before so you are on your own, but it is the only download option that I know about.

Try booting the MBP with the OPTION+D keys. It may work.

Doesn’t work. That’s where the error message comes from. Pressing D only works if you have the install DVD in the drive, Option + D loads Internet Recovery and is supposed to work as long as you’re connected to a network. Using this option is what’s causing said error message.

Stokd is right, the error come with option +D.

MY MBP was working very well with yosemite (mid 2010 build) until it ‘updated’ last week. Now I can’t even use it without it crashing!! I’m so annoyed. I get the impression that the newer the software & the older the machine, the less likely these two will cooperate together! Are there any clever techies out there who can help diagnose the problem before I wipe the hard drive & re-install from a back up? I’m only glad I have an iPad to use while I’m stuck with this problem! 😠

Same here. MacBook Pro mid-2010. Having problems since Yosemite install a month or two ago. Nothing happens when I try to boot holding down the d key. The system just sits until I release the d key, at which time it reboots in normal mode. Option-d causes the error everyone else is getting here.

Nov 30, 2015 5:53 PM

To use the internet for the apple hardware test, your Mac had to ship with at least Lion. Otherwise you have to have the install dvd that came with the Mac. Not a retail version, but the machine specific software. https://support.apple.com/en-us/HT201257

Nov 30, 2015 6:06 PM

Feb 4, 2016 10:07 PM

To all that get that code. It means your Mac cannot do the hardware test from the internet. You need the install disk that has the hardware test on it. Then you boot it and hold down D or Command D at startup.

Feb 4, 2016 10:29 PM

Very strange i am having the same today? Coincidence?! I am trying internet recovery.

my ginger’s solution is what worked for me. I can’t do internet recovery on my mac—it’s a bit too old. I used the dvd that came with the mac and that worked fine. Showed no hardware errors, but worked. The overall problem I was having was with the video card. Got that replaced and I’m back in business.

I have this same issue but mine has lines on it won’t let me boot up regarly any more.

Feb 25, 2016 11:06 PM

I first also had trouble. Funny thing was that with the power connected the led in the connector near the laptop was not green or range but not doing anything. Then I disconnected the connector to the white square block (with power still connected) and the led was again green. Very strange! Then the laptop booted and I could do the restore process ( Created bootable El Capitan USB / Installed fresh version of El Capitan / Restored data with Time Machine ).

Feb 26, 2016 2:46 AM

Finally, determining if your computer supports loading Apple Hardware Diagnostics over the internet isn’t necessarily easy to do using the info from Apple. Quoted from their webpage, » Some Macintosh computers that shipped with OS X Lion and later support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT. «

Some? How helpful is that? Why don’t we throw in «may» and «possibly» and how about «we don’t really know» for good measure.

I have an early 2011 MBP 13 that does do the AHT over the internet, and a Mid 2010 that doesn’t, so for the 13s that appears to be the cutoff. How hard was that, Apple? FFS

Same here. MacBook Pro mid-2010. Having problems since Yosemite install a month or two ago. Nothing happens when I try to boot holding down the d key. The system just sits until I release the d key, at which time it reboots in normal mode. Option-d causes the error everyone else is getting here.

To use the internet for the apple hardware test, your Mac had to ship with at least Lion. Otherwise you have to have the install dvd that came with the Mac. Not a retail version, but the machine specific software. https://support.apple.com/en-us/HT201257

This is straight from someone at Apple, ” That -3403D code actually means there was an issue with your Mac software configuration “

To all that get that code. It means your Mac cannot do the hardware test from the internet. You need the install disk that has the hardware test on it. Then you boot it and hold down D or Command D at startup.

Very strange i am having the same today? Coincidence?! I am trying internet recovery.

my ginger’s solution is what worked for me. I can’t do internet recovery on my mac–it’s a bit too old. I used the dvd that came with the mac and that worked fine. Showed no hardware errors, but worked. The overall problem I was having was with the video card. Got that replaced and I’m back in business.

I first also had trouble. Funny thing was that with the power connected the led in the connector near the laptop was not green or range but not doing anything. Then I disconnected the connector to the white square block (with power still connected) and the led was again green. Very strange! Then the laptop booted and I could do the restore process ( Created bootable El Capitan USB / Installed fresh version of El Capitan / Restored data with Time Machine ).

While this may be true, it is odd that the machine appears to attempt to load the hardware test (it goes through all the correct motions before bringing us to the -3404D error). Further, why not simply give a message like, “Sorry, hardware test via the internet is not supported on this Mac,” rather than some unhelpful, cryptic message?

Finally, determining if your computer supports loading Apple Hardware Diagnostics over the internet isn’t necessarily easy to do using the info from Apple. Quoted from their webpage, ” Some Macintosh computers that shipped with OS X Lion and later support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT. “

Some? How helpful is that? Why don’t we throw in “may” and “possibly” and how about “we don’t really know” for good measure.

I have an early 2011 MBP 13 that does do the AHT over the internet, and a Mid 2010 that doesn’t, so for the 13s that appears to be the cutoff. How hard was that, Apple? FFS
