Today there are quite a lot of utilities for testing and diagnostics. personal computers. Moreover, not all of them are created only for troubleshooting. Some of existing applications help identify “weak” areas and can even provide a number of useful tips. A utility called TechTool Pro is one of these.
TechTool Pro is a fairly popular utility for testing an Apple computer, which is distinguished by its wide capabilities and pleasant interface. Thanks to this, it can be used by both beginners and advanced users.
One of the main tasks of TechTool Pro is testing hard drive Mac. The utility allows you to scan drives for bad partitions, restore access rights, perform SMART tests, and clone volumes.
However, TechTool Pro's monitoring capabilities hard state disks are not running out. This application also allows you to test other components of your Apple computer. For example, check the operation of coolers, random access memory, monitor, etc.
To summarize, TechTool Pro is a powerful application that can replace an entire arsenal of diagnostic programs. But this utility has one significant drawback - the price. Latest version programs will cost $99.99. You can purchase TechTool at.
The easiest way to avoid the help of service centers when searching for hardware problems (not all of them can boast of a good reputation) is to use the built-in Mac diagnostic methods. In this material we will tell you how to launch and use " " And " Apple Diagnostics».
With help regular funds diagnostics can effectively detect hardware faults (hard drive problems, solid state drive, RAM, GPU, motherboard and other nooks and crannies of hardware). How to do this?
On which Macs which utility?
Regardless of (MacBook, iMac, Mac mini or Mac Pro) and its year of manufacture, operating system includes a utility for hardware self-diagnosis. On computers manufactured before June 2013, it is called “ Functional test of Apple hardware"(Apple Hardware Test - AHT), and after - " Apple Diagnostics».
Before running any of the utilities, be sure to disable everything peripherals(including optical drives, if such antiquity still exists) except for the keyboard, mouse, display and Ethernet adapter. Some versions of OS X Lion and later may require Ethernet or Wi-Fi to run the Internet version of AHT. It is no different from its offline counterpart.
To use AHT, be sure to connect your MacBook to a power source.
List of keyboard shortcuts
If you don’t have a mouse, the following shortcuts will come in handy:
- Option (⌥) + D: run diagnostics via the Internet;
- Command (⌘) + G: start operation;
- Command (⌘) + L: display a list of languages;
- Command (⌘) + R: run the test again;
- S: shutdown;
How to Run Diagnostics on Mac (Apple Hardware Functional Test or Apple Diagnostics)
Note: " Functional test of Apple hardware" And " Apple Diagnostics" work in the same way. The only caveat is for launching " Apple Diagnostics“An active Internet connection is required, and the interface will be much nicer.
1 . Turn on or restart your Mac if it's turned on.
2 . While turning on, press and hold the " D» until the language selection screen appears.
3 . Select a language (if a mouse is not connected to the computer, then select a language using the arrows and enter with the “Enter” key).
4 . Mac diagnostics will begin.
After the test is completed, the results will be displayed.
To exit the ANT utility, click the " Reboot" or " Switch off"at the bottom of the window.
What do the results say?
If problems with the hardware are detected during the test, then get ready to see an error and some explanatory details.
You can decipher AHT errors on the Apple technical forum, and in general I recommend that you go there first when looking for solutions to problems with Apple gadgets. True, you will need knowledge of English, at least with a dictionary.

In any case, if it was not possible to avoid repairs at the service center, we strongly recommend that you contact only certified specialists who specialize exclusively in Apple equipment. It won’t be cheap, but purchasing a new gadget is much more expensive. It’s better to completely forget about the basement workshops “at Uncle Vasya’s”. Repairing Apple devices requires a very meticulous approach and advanced skills.

Determining the cause of the malfunction is the very first thing you need to start repairing your MacBook. And the point here is not that “this is how it should be,” but that replacing components in Apple laptops is a very expensive process, so you should be absolutely sure that it is really necessary.
Cost of services:
Problems that a MacBook user may encounter can be divided into two groups:
Software
They are associated with incorrect installation and operation of the Mac OS X operating system or software. In this case, problems occur directly during or after working with an application or may occur with a certain frequency.
They are caused by a malfunction of laptop modules such as the MacBook motherboard, HDD, matrix, etc., and in this case, repair or replacement of MacBook components will be required.
Stages of self-diagnosis of a MacBook: what you can do before contacting a service center
- If you excluded software glitch, the cause of the problem may lie in connected but malfunctioning equipment. Turn off the device and try to disconnect all external equipment, leaving only the mouse. If the laptop starts working normally, then further diagnostics of the MacBook will consist of alternately connecting the equipment and turning on the laptop. This way you can determine what exactly led to the problems.
- If this does not help and the laptop continues to operate in an incorrect mode, you should check the hard drive and also rule out problems with access rights. To diagnose a disk in a MacBook, there are two programs - Disk Utility and the fsck command (the latter is used for MacBooks with OS X 10.4 or earlier). The check must be carried out in a safe mode.
- You can use Hardware Test to diagnose MacBooks running OS X 10.7 or later, or Apple Diagnostics for devices released in July 2013 or later. In this case, it is very important to turn off all external equipment and also connect the laptop to the network.
- To enter MacBook diagnostic mode, you need to hold down the D button after turning on the laptop. gray screen, and you will be able to run a utility to check the hardware (you can select full check or partial). If the diagnostics are successful and the cause of the failure is identified, a message will be displayed with a record of the corresponding error.
Full diagnostics of MacBook - only at the service center
The ability to independently diagnose a MacBook is, of course, wonderful, but a complete picture of the laptop’s performance can only be obtained by contacting a service center. For example, if the computer does not turn on or maintenance has not been carried out, the cooling system has failed, the battery has been damaged, or Charger, it will be possible to determine the cause of the malfunction only after disassembling the laptop and testing the circuit. The MacBook will also need similar diagnostics if it has been dropped or flooded with liquid.
Disassembling an Apple laptop is not easy even for a specialist, so you shouldn’t try to open the case and get the components yourself. Contact the service center - and the MacBook will be thoroughly diagnosed, and the technician will be able to determine the exact cause of the equipment malfunction.
Check with the manager by phone for the exact price for repairs.

Question about work MacBook keyboards Pro 2011~ Pavel ~ 06/15/2016
Good day!
I have a MacBook Pro 2011 Unibody. I clean it periodically and change the thermal paste. During the last thermal paste replacement (disassembly, removal of the motherboard), I inadvertently damaged (torn off) the touchpad cable. Having decided that before replacing it I would use the mouse, I assembled it, which in general is not the first time I’ve done it, and I discovered that the keyboard did not work either. After that, I disassembled and checked the keyboard cable a couple more times, but there was no result. The keyboard is silent. ((Tell me what could be the problem? Could the non-working touchpad on the example be somehow connected with the keyboard? Or maybe another option? And also how much does the cable for the touchpad, the keyboard and the cost of work cost?

Problem with discrete monitor ~ Daniil ~ 05/31/2016
Hello, I have an MBP 13" late 2011, when I connect a second monitor via a Mini DP - VGA adapter, the image appears on it for a second and disappears. If you leave it like that for a minute, the Mac starts to slow down a lot and artifacts appear. If you manage to set the resolution on the second monitor ~1360x780, everything works fine, and the monitor works (although sometimes it blinks, about once every 30 minutes). The problem is most likely not in the software (I checked both on OSX and on Windows via Boot Camp, reinstalled the OS) and not with the adapter (I checked on MB 13" 2010, everything works fine at 1920x1080). What could be the problem? The card reader also does not work (the system sees it, but does not read the cards), which means the problem is not in the video card, but in the motherboard?
Macsave Center Answer: Good afternoon, apparently the problem is in the bridge, they have video and power management there

Problems with MacBook Pro~ Nikita ~ 12/21/2015
Good afternoon. Unpleasant and unexpected things happen to my poppy. The Mac is a little over a year old, has never let me down and worked perfectly. For the last three days, the following has been happening to him:
My Mac has more than 20GB of free space, but in recent days, as soon as I turn on my Mac, the memory melts away in a matter of minutes, it displays a message that the startup disk is full, requires me to close all programs (and closes them myself) and the memory shows 0kb. That is, the operation of the poppy can take no more than 10 minutes. Afterwards I have to recharge it (which unexpectedly also caused problems and it doesn’t respond every time). After the reboot, there are again about 27 free GB, and every time I check it, I remove a lot more from the Mac to clean it.
In this situation, I turned off the Mac before going to bed, and in the morning I discovered that it had not turned off and the battery charge was zero. The monitor, as far as I remember, went out.
I’m used to the fact that after leaving for about 15 minutes, Poppy goes to sleep. Having got ready for business in the morning and returning in the evening, I discovered that the Mac’s monitor was on as it was a few hours ago. He did not go into sleep mode.
What could all this be connected with?? All this happened starting from December 18 (4th day), before that it worked properly.

Macbook pro mid 2014 turns off randomly~ Albert ~ 03-12-2015
Hello. MacBook Pro randomly turns off. Completely random. I carried out diagnostics using the laptop itself, it says that the battery requires servicing. I decided to check that the problem really was there. I unplugged the battery plug and started working purely from a 220 volt network. The laptop started to work slower, but stopped randomly turning off. Does this mean that the problem is really in the battery?
Macsave Center Answer: Good evening, the problem is probably in the battery, the brakes may also be due to a damaged battery, the cost of replacement is 8000-9500 depending on the model

MacBook Pro retina 15 won't turn on ~ Ivan ~ 05/19/2015
Good afternoon Doesn't turn on MacBook retina 15 2012 Most likely something happened due to overvoltage. The heater was turned on in a nearby outlet when the beech was plugged in. After that, the beech stopped turning on, and where the heater was turned on, the surge protector burned out. The charge is intact, I checked it on another Mac.

I would have sent it to your center for diagnosis and treatment a long time ago, but I am very far away, and in our city there is no apple service. What would you recommend?
Macsave Center Answer: Good afternoon, you clearly have a problem in the power supply circuits of the motherboard
MacBook Pro 15 (Late 2008)~ Dmitry ~ 05/16/2015
Hello, the insulation near the L-connector was peeling off, I decided to re-solder it - I crushed the LED and broke off a piece of the board when I tried to remove it. The Mac worked from the mains, but stopped charging the battery. I ordered a new cord with an L-connector, while waiting for the cord the battery discharged to 1-2%. I managed to turn off the Mac normally.
I soldered a new cord, plugged it in, the Mac won't start. I installed the battery and it started. But! The indicator on the L-connector DOES NOT LIGHT! (neither green nor orange) I thought it was a Chinese counterfeit, I thought there was no LED at all. The Mac works on mains power, sees the battery BUT does not charge. With the Mac running, I took out the battery, ran it for a while on mains power, then hooked it up and pulled out the plug. The Mac switched off and then stopped starting, either with or without the battery. I read that resetting the SMC can solve the startup problem. But when resetting, the Mac doesn’t react in any way, the indicators are silent, and it still won’t start.
Since the battery was swollen, and there was also a complete discharge, I ordered a new A1281. PRAM/NVRAM reset after forced startup* (without battery). No changes either.
*(Disable MagSafe, hold Power for 5 seconds. Without releasing, connect MagSafe, hold Power for another 5 seconds, release, wait a couple of seconds, launch the Mac). The Mac started up forcibly, but with all the problems that arise, it is necessary to reset the SMC (Indicators-Fans-Lighting-Power).
A new battery arrived: the Mac started up forcibly*, but it says: No battery Power source: battery. (B-rr-rrrr)
I took the Mac (without battery), the charger and went to the neighboring city, found an Apple point. The seller had an Air with 60w, connected its Magsafe to mine - the indicator lit up green, but after 10 seconds it dimmed and soon went out completely (what the hell - I think that’s it! I burned the guy’s MagSafe), plugged it back into my Air - it works. My Mac wouldn't start due to lack of power. We took my 85w with a soldered new cord - L-conn. We inserted it into the Air and it lit up green!!! Hooray! The cord is still working. I put it back into mine and there is no reaction.
Results: replaced the cord with the L-connector, bought a new battery.
The Mac only starts forcibly, SMC is not reset. The LED on the plug does not light up. On the battery charge indicator, the 6th indicator is constantly shining, whether from the network or from the battery. I checked that power is supplied to the MagSafe board and from it to the Mother board in full. All contacts are called. Maybe there is some diagnostics that can be done at home besides (D-at startup), everything is clean there.
Macsave Center Answer: Good afternoon, everything clearly points to the motherboard power circuit. Only diagnostics at the service center will help

What about him? ~ Evgeny Voevodin ~ 04/07/2014
Hello!
I have a macbook air 13 inches, mid 2012. OSX 10/9/2 The problem is the following: it works great, does not heat up, does not glitch, incl. under load, only if it boots. And it loads within a couple of hours - easily, maybe longer. First, the white screen lasts 20-40 minutes, then the user’s choice, the same amount, slows down unrealistically, asterisks when entering a password are displayed with a delay of at least 5 seconds. But after that, when exiting sleep mode, there are no problems.
The problem is that I’m in Sevastopol, local technicians can’t advise anything except how to replace the motherboard, and they can’t do that either... I’m sitting here thinking about buying a new one, or is it some kind of typical problems for a specific problem with a specific final cost. Thank you!
Macsave Center Answer: Good afternoon, problems often occur in Hard drives SSD and cables on the MacBook motherboard, the south bridge could also fail. A full diagnosis is required.
Installing the operating system macbook a1181 ~ Stanislav ~ 03/17/2014
Good afternoon, I have the following problem, I will try to describe it step by step.
I have a macbook 1181, it was inherited, so to speak, the previous owner did not spare it much.
At some point the operating system stopped loading. After starting the laptop, an apple icon appeared and a rotating circle underneath it, then nothing happened, I tried leaving it overnight, and the same thing in the morning.
According to the previous owner, this has already happened to him, the operating system also crashed, this was solved by reinstalling it. Latest OS 10.7.4
When I try to reinstall the OS on the same 10.7.4, the system freezes while preparing for installation. I waited for several hours, no result.
I replaced the hard drive in the laptop, formatted it according to the instructions, tried to install OS 10.6.3, the same situation, it recorded in the last minutes of loading. At some point it just loaded, after which the screen went blank. I forcibly rebooted it and left it to boot from the hard drive, it spun (about 30 minutes) and played a melody, but the screen remained gray.
The last time I tried to reinstall the OS, the process froze about 30 minutes before completion (the screen worked, but did not respond to the touchpad).
I also tried changing bootable USB flash drive, The result is the same.
Please tell me what could be the matter?
Macsave Center Answer: Good afternoon, this is often how problems with hard drive, the time has come to change the hard drive in your laptop because in the Mac A1181 during this time more than one hard drive has changed, as an option the north bridge may be, but this is rare.

Small MacBook 11 screen does not work ~ Yana ~ 09-10-2013
Hello, I have an Apple Air 11 screen on the bottom that says MD508. Help me fix my baby, I turn it on with a button, but it doesn’t give any life signals, everything is silent and the screen doesn’t light up, as I understand it, I need to do diagnostics?
Macsave Center Answer: Good afternoon, there may be a problem with the MacBook’s power connector or a power problem on the motherboard, we’ll do diagnostics within a day and tell you what the problem is on your Aira.
Not all owners Mac computers know about the presence of equipment built into the test system.
The diagnostic tool can help identify problems with your drive, RAM, video card, or motherboard without a visit to the service center.
Which Macs have this utility?
On Mac computers manufactured before mid-2013, the diagnostic tool was called "Apple Hardware Test".
Since mid-2013 Apple Hardware Test replaced by Apple Diagnostics, the utility requires a network connection via Wi-Fi or Ethernet to operate.
When you need it
If your Mac starts to glitch for no reason, freezes, thinks for a long time without much load, gets very hot, or simply won’t turn on, you should run this test.
It would be useful to check the equipment if there is any suspicion of mechanical failure, for example, after the computer has been dropped or after the device has gotten wet.
How to run hardware diagnostics
Make sure your computer is within range of a familiar Wi-Fi networks or connected via cable. If you are using a laptop, connect it to the charger.
To run Apple Hardware Test or Apple Diagnostics you need:
1. Turn on/restart your Mac, hold down the button while turning on D on keyboard.
2. Select the desired utility language.
3. Wait until the utility finishes (usually the process takes several minutes).
In the report you will see the error code (if any) and a brief description.
How to understand what the problem is
Error code "ADP000" indicates that there are no problems. You can restart your computer and work normally. Other codes indicate problems with the hardware.
The decoding of all codes and subsequent actions are described in detail on the Apple website.
Why is all this needed?
Attentive readers will notice that in most cases it is still recommended to visit a service center to solve the problem, and no one wants to tinker with an expensive Mac on their own.
Why then bother with diagnostics and determining the cause of the malfunction?
Firstly, problems may arise after upgrading at home. For example, I installed the RAM bar, but it broke. There is no need to go to the service center: I pulled out the memory and changed it to another one.
Secondly, if some old port or connector is broken, you can simply not use it. For example, a failed Thunderbolt may require replacing the motherboard, which is a rather costly repair. An old Mac user would rather find alternative way connections.
Third, when you go to the service center, you will be armed with the information from this test. To prevent repairmen from trying to rip off money for expensive repairs, it is better to know the cause of the breakdown.
⭐ Thanks to re:Store for the useful information.
Please rate it.
If you start to notice problems with your Mac (for example, it starts freezing or rebooting on its own), the first thing you need to do is identify the cause of the incorrect functioning.
In this case, you can immediately take the laptop to an Apple service center, if, of course, there is one nearby, or try to deal with the problem yourself. Let's look at how to test a Mac at home.
Built-in Mac Diagnostics
Malfunctions that may occur in Mac work, can be combined into two groups:
- software – conditional incorrect installation OS or additional software;
- hardware – consist in the failure of a certain laptop module (HDD, video card, RAM, etc.).
To eliminate a software failure, you simply need to remove the software that caused it or reinstall the system. Hardware problems require a more rigorous approach, which consists of repairing or replacing the non-working element.
To identify hardware damage Apple company equipped its computers with built-in diagnostic tools. On laptops manufactured before June 2013, you can run the test using the Apple Hardware Test (AHT) utility. On later Mac models, this application is called Apple Diagnostics. There is no fundamental difference between these programs, since they launch and work the same. The only thing that needs to be taken into account is for Apple usage Diagnostics requires connecting the PC to the Internet via wireless network or Ethernet.
Testing a Mac with AHT or Apple Diagnostics
Before you run Mac diagnostics, you need to disconnect all peripherals (speakers, web camera, printer, etc.) from the laptop, except for the optical pointer, keyboard and network adapter. It would be a good idea to connect a power source.
Further actions will be as follows:
The duration of the test depends on the configuration of the MacBook and averages 2-3 minutes. Mac diagnostic results can be seen in the corresponding window.
Error codes
If the Mac diagnostic program detects problems with the laptop’s hardware, you will see an error code, the reasons that caused it, and possible options solutions. The decoding of the received code can be found on the Internet in Russian at the link.
If the damage is serious and you cannot get rid of it yourself, you should contact your nearest Apple service center. At the same time, you shouldn’t trust your MacBook to ordinary repair shops, even if they are reliable, because repairing Apple equipment requires a specific approach and special skills from the technician.
If your MacBook is under warranty, you will need to contact Apple online support and provide the error code. After this, the company’s specialists will tell you what to do next and whether you need to contact the service center.
