De batterij van de macbook was zelf ook al niet helemaal goed meer, gaf een service melding en viel bij ongeveer 35% zo af en toe uit.

Wat kan hier de oorzaak van zijn, wat valt er aan te doen om hem weer aan de praat te krijgen en is dit überhaupt nog mogelijk?

Buiten de problemen met de batterij werkte hij namelijk nog goed en nu doet hij helemaal niks meer.

Alvast bedankt voor mogelijke suggesties.

J’ai changé la batterie de mon MBP (kit ifixit) et au redémarrage, mon trackpad et mon clavier ne répondent plus. Je n’ai seulement accès au bouton POWER mais rien d’autre ne répond.

Voilà ce que j’ai déjà tenté:

-Changé nappe de connections trackpad (long cable plat en L retourné qui se trouve par dessus la batterie).

-Réinitialiser SMC + NVRAM/PRAM

-Redémarré en mode sans échec…

Voilà, aucun raccourci ne fonctionne, rien ne change au démarrage suivant ma combinaisons de raccourcis…

HELP haha je ne sais plus où chercher…

Merci pour votre temps

Kan iemand me helpen zoals jullie zien werkt het scherm van mijn Macbook niet meer . Kan iemand me uitleggen wat de oorzaak is en hoe ik dit zou kunnen oplossen.

Wat doet ifixit met hun "nieuwe" batterijen die al meer dan 5 jaar oud zijn?

⟐ Answer accepted februari 24, 2026 at 1:58 MST

Ik wil dit probleem eerst oplossen voordat ik mijn batterij zal vervangen, maar misschien moet ik gewoon een nieuwe MacBook kopen.

Alles werkt perfect, behalve de performance probleem en het wordt snel warm. Mijn battery health is 70% dus dit veroorzaakt hoogstwaarschijnlijk mijn performance probleem en natuurlijk de thermal paste voor de oververhitting. maar ik zie echt niet wat de crack geluid veroorzaakt.

Eergisteren is mijn MacBook Pro uitgevallen terwijl hij in de oplader stak. Hij was volledig plat & het duurde even voor ik hem weer kon opstarten. Nu heb ik al gemerkt dat hij al een tijdje soms niet echt oplaad terwijl de oplader wel insteekt. Als ik hem dan weer uittrek en weer insteek is het probleem verholpen.

Nu nadat hij volledig is uitgevallen, heb ik hem na een tijdje weer kunnen opstarten, maar nu blijft het oplaad icoon hangen. Hij zegt dus dat hij oplaad of dat icoon staat toch op opladen, terwijl hij niet in de stekker steekt. Als ik hem wel insteek, werkt de lader meer niet dan wel.

Ik dacht dat het een probleem was met de lader, dus heb ik deze getest met mijn iPad Pro, en deze laad wel perfect op met dezelfde lader.

Weten jullie wat het probleem is?

Er zit zo’n dubbele speaker in dus ging ik er vanuit dat degene die de mid/lage tonen geeft wellicht kapot was gegaan.

Nu heb ik gisteren beide speakers vervangen, alleen is hiermee het probleem niet verholpen en heb ik nog steeds exact hetzelfde probleem! de rechter speaker geeft wederom enkel hoge tonen (en lijkt te kraken) in tegenstelling tot de linker speaker welke wel normaal functioneert… Help!

Softwarematig:

• Als ik in midi-configuratie de kanalen Switch blijft het probleem aanhouden aan de rechterspeaker.
• coreaudiod forceer stop maakt geen verschil.
• sudo killall coreaudiod geeft geen verandering.
• Command, Option, P, and R opstart maakt geen verschil.

Het lijkt dus geen software probleem te zijn?

Hardware:

• Oude speaker geïnspecteerd, ik zie hierin geen overduidelijke scheurtjes, de speaker lijkt niet kapot te zijn? (wellicht intern)

Mijn vraag is dus, waar ligt het probleem? heb ik toevallig een speaker set gekocht waarbij de rechterspeaker precies hetzelfde probleem heeft? (speakers gekocht via mmobiel) zit het probleem ergens anders in de hardware? of kan het toch als nog ergens in de instellingen verkeerd staan?

enige oplossingen die ik zelf nog zie is om e.v.t een complete OS re-install te doen om te kijken of dat het probleem verhelpt.

en om wellicht de linkerspeaker die ik vervangen heb (waarvan ik weet dat die wel werkt) aan de rechter speaker poort te connecten om te kijken of er dan ‘'normaal’' geluid uit komt.

wat denken jullie? zijn er nog andere opties? let me know!

Is there any repair instruction to be found? Or is there a replacement cable without replacing the adapter?

Mijn logic board, specifiek de RAM, van mijn MacBook (early 2013, 15” Retina) is kapot. Ik wil graag mijn logic board vervangen, maar twijfel of ik elke versie 15” early 2013 kan gebruiken om m'n MacBook weer werkend te krijgen.

Ik wil m'n laptop ook meteen een upgrade geven door het 16 GB RAM logic board er in te stoppen, wat eerst 8GB was.

Gaat dit werken/passen?

Alvast bedankt :)

My iPhone has connected perfectly until today, when it started doing the same thing as the iPad. All other USB devices work fine, and my iPad and iPhone both connect with the windows computers at work just fine. I've tested with both USB ports on my MacBook, and with several known working cords, both Apple branded and not.

I've done a lot of searching, and haven't found any definitive answers or solutions, but today I thought I would try something.

I use Windows 10 in VMWare on my laptop for work (and yes I made sure it wasn't running before trying to sync to make sure that wasn't causing the connectivity issues). But today I opened Windows on my MacBook, and when I plugged in my iPad I told it to open in Windows, and voila it connected to iTunes in windows fine and stayed connected.

This leads me to believe it is some sort of software issue on the MacBook side of things. I even tried closing itunes and just plugging my phone in to charge, and it again acted as though I was continuously plugging it in and unplugging it, but stayed connected in Windows.

Is there something I can do to correct this? I thought it might be an iTunes issue, but since it wouldn't even keep my phone connected enough to charge without iTunes open, I'm assuming it's an OSX issue.

Any suggestions would be greatly appreciated!!

So, when I put my MacBook in the charger and click the on button it went on for 5 sec and then turned off. I pushed the button again and now I could login I looked at the battery it was still 80% so I thought that's odd.

Then when I logged in it shuts off again. I've tried for several times to turn it back on sometimes it didn't even turn on and sometimes it turns on and then it shuts off again after seconds.

I went to a computer store but they didn't know what was going on the guy said that he couldn't find anything weird in my MacBook (software) yes of course when the guy looked at it it worked. Until it suddenly shuts down and I was like: 'Yes that's the problem!' But he had no clue. All he said was: 'send it back to apple'

So another thing: I'm traveling and need my MacBook for my work (I'm a colorist and work in the film industry) I need it everyday.

Maybe something important: last June I Accidentally closed my MacBook with the charger between so my display broke. I replaced it, cost me lots of money, and then after 2 months it was loose (I haven't fixed it yet, been more than one month now)

I can move my display up and down for at least 1cm. I can also detach the black bar underneath the display from the display, think this used to be glued together.

I don't know if this might be the problem from the MacBook shutting down randomly.

Ps. Sometimes my MacBook doesn't shut off completely and the fans start making extreme noises. It's like my MacBook is frozen.

Mid 2015 with Retina display

• 2,5 years old
• Used daily
• MacOS Sierra

I've turned it on again and clicked the D that brought me to some sort of check. It said: nothing is wrong.

Now it just restarts randomly. It's better but still not 100%

Error: 8000000000000003, Cannot load 'EFI/Drivers/TestSupport.efi'

Status: 0x00000003

Which sits there for about five minutes, then it restarts into MacOS.

Same result when I try to run AHT from a USB stick, except this time it shows the above message twice – flashing by so quickly I had to get a video of it to see what it said – then immediately restarts into MacOS.

The OS version of Apple Service Diagnostic works okay (it has an OS on it, and shows in the Startup Disk preference Pane), but the EFI version gives the same result as above.

I've reset the SMC and NVRAM, and reinstalled the OS (Sierra) numerous times, to no avail.

I ran both AHT (Internet & USB) and ASD/EFI successfully a couple times only a few months ago; something's changed, but I can't figure out what.

However, MemTest86 (which also starts up from an EFI driver from a USB stick) still works fine with the MacBook Pro. So it seems this MBP is now somehow allergic to Apple's own EFI driver?

The same hardware (USB stick for AHT, external HD or USB stick for ASD) works fine with four other Mac portables, and two of them can access Apple Diagnostic (the 2014 & later version of AHT) from the Internet as they're supposed to (the others are too old to do so). So the problem is definitely something in this MacBook Pro.

The MBP was showing other problems as well; I sent it to a repair service, who said the GPU needed fixing (apparently common in this model), which they did, and said the logic board now tested all good. But it still "Cannot load 'EFI/Drivers/TestSupport.efi'".

I spoke with somebody at Apple Support, who was mystified, suggested maybe it had something to do with the SSD? The SSD seems to work fine otherwise, starts up okay etc., and DriveDx (which gives detailed readout of SMART parameters) says it is good.

Anybody have any idea what the problem might be? I plan to sell this MBP, but can't do so in good conscience as it is, even if it seems to be working okay otherwise.

Thanks for your response, Dan.

Yes! This is an issue with in Apples newer MacOS EFI/SMC updates.

When I posted the above, I thought it was a problem with my MacBook Pro; I've since learned that it's a common problem afflicting hundreds (at least) of Mac users. It is beyond ironic that the software Apple offers to its users to diagnose problems with their Apple hardware… doesn't work. So we're all waiting for Apple to get off their collective posterior and fix it.

There's a ton of people encountering this Unable to launch Apple Diagnostics Apple altered the EFI so all versions of MacOS are effected from Sierra on up is where I've seen it.

Yes, I also posted my query at Apple Discussions: MacBook Pro 2013 - cannot load Apple Hardware Test, and was referred to the Unable to launch Apple Diagnostics thread (which now has 163 "I have this problem too" clicks, while mine has 5). See my posts here and here for more detail and follow-ups.

I spent an hour and a half on the phone with an Apple Senior Advisor on Tuesday (May 28) about this issue, trying everything he could think of (he apparently hadn't heard about this before), ending with sending a bunch of information, which he said would be forwarded to some "engineers", who would get back to me in a few days. I provided links to the two Apple Community threads and emphasized that there are over 150 people now waiting for an answer. I'll post whatever I hear in the Unable to launch Apple Diagnostics thread, for anybody who's interested in following the issue.

The Apple Hardware Test (AHT) repair doens't fix this in Mojave.

Not sure what you mean about the "AHT repair"; the link is to a very helpful post at GitHub that tells how to get and use AHT for various old Macs dated prior to June 2013, when AHT was morphed into Apple Diagnostics, which is now available only over the Internet (or from the Recovery partition in High Sierra or Mojave, as I discovered in my research). See my second post in Unable to launch Apple Diagnostics for more detail about AHT/AD. Anyway, AHT doesn't "repair" anything; it's a simple diagnostic utility – and it won't load/run in any of the Macs that Cannot load 'EFI/Drivers/TestSupport.efi'.

Apple holds the cards for their diagnostic software. You could try calling them most likely they'll send you to a authorized service center if there's one near you.

Oh, yeah, about that… All this started for me in early 2018, when the intermittent crashes etc. I'd been experiencing with this Early 2013 15" MacBook Pro finally became intolerable. I didn't want to be without a computer while I was figuring it out, so I bought a 2015 MBP (still new with warranty, found on eBay). I then took the 2013 MBP to the local AASP, asked them to diagnose it, for which they charged me $60. Presumably they ran Apple's in-house diagnostic utility/ies.(The guy said something about the "EFI version"; I didn't know what that meant at the time.) They told me the 2013 MBP was fine. (The new 2015 MBP turned out to have problems also, and I ended up struggling with both – along with my long-term chronic illness – all year, until finally early this year I got together enough energy to try to deal with them.)

But my MacBook Pro wasn't fine. So I bit the bullet and did some research, learned that both Apple Hardware Test and Apple's pre-2015 in-house diagnostic software Apple Service Diagnostic could be found on the 'Net. So I got them, figured out how to use them, and they both found both several memory problems and a few others that are more of a mystery to me (I'll be posting those elsewhere here to ask if anybody can figure them out).

I was able to run both AHT and ASD on the 2013 MBP several times, until suddenly in the last month it told me it Cannot load 'EFI/Drivers/TestSupport.efi'. (It still runs the OS version of ASD, but won't run the EFI version.) It seems likely the fact that I'd installed both High Sierra and Mojave on it a month or two before, which may have changed the Boot ROM version (I don't know what it was before) might have caused this problem. Although, as noted in my post at Apple Discussions, I recently experimented by installing Mojave on a 2014 MBP, which didn't change the Boot ROM version, and didn't cause the Cannot load 'EFI/Drivers/TestSupport.efi' error. So we still don't know exactly what's going on.

Anyway, the nearest Apple Store is too far away for me as well, and my experience with the local AASP does not give me much confidence.

The ball is in Apple's court.

If I slowly close the lid to about half way, the lines will disappear.

Only to reappear when the lid is opened again. Obviously a connection problem. This is a work computer and the repair shop quoted work $3000+ for this repair. Ludicrous. Also, no apple care was purchased so this barely-more-than-a-year-old top of the line Apple computer is suddenly worthless.

I'm not afraid to open the case, but could someone direct me to the cable that I should unseat and reseat, or perhaps even replace?

Any help greatly appreciated.
