2015 Macbook Pro stuck in a Boot Loop Reboots Restarts continuously 

Awesome video man! Thank you so much! My loaded mid-2015 MBP all of a sudden died one day and then got stuck in a boot loop any time I plugged in the power cord. It did not run on the battery at all and I cannot open into safe mode or any other mode, it just was stuck in a boot loop. I took it to Apple a few weeks ago and they reloaded the OS but said it was stuck in a boot loop and the logic board was shot. I mentioned that the battery was also shot and asked if that could be the reason for the boot loop. They told me no way it’s definitely the logic board. So I decided to pay $85 for a battery from OWC, installed it, and the computer fired right up with no problems. Amazing that even Apple could not diagnose the boot loop problem. However, Apple did know that the battery was bad but told me that replacing the battery would not fix the problem. Really appreciate the video, thanks again! 😁👍

This is the only video that documents my exact problem. Strange thing is mine is brand new, just over a year old. Crossing my fingers it’s a battery problem.

You, sir, are a genius and saved me an incredible amount of time. I was completely perplexed, because it just doesn't make sense why it would be designed this way.

So glad I found this video. Same issue - mid 2015 MBP that I continually had on the wall charger due to running under heavy load with a battery in unhealthy state for over 2 years. Finally resulted in an endless boot loop which three Apple techs told me had nothing to do with the battery's inability to hold sufficient charge. I popped the bottom cover off and saw that a few of the battery cells were badly swollen. My plan was to buy an iFixit battery kit for US$110, but decided to skip the hassle and have Apple do the repair. In the end, I opted for a genuine Apple battery and 90 day warranty. I would add that the repair included a full replacement of the top deck, including the keyboard. Easily worth the extra $89 for me. Thanks again.

Thanks for this video - saved me countless hours!!

very well done, happened to one of my MacBook Pro 2011, now it is working again! BRAVO

Legend, thank you for posting, this fixed my early 2011 macbook pro, probably common to quit loading when battery faulty to reduce fire risk, must be a feature for a while, the battery on my 2011 macbook was fully dead, thank you so much, good man!

Seriously great video! Saved me many hours too! Thanks for finding this out!

I know I'm a few years late on this video but nice catch. It makes sense if the battery is on it's way out. I have a 2016 MBP so I'll keep this in mind. Thank you.

Don't know if you will see this comment, but this video fixed my boot loop 2017 Macbook Pro. Just disconnected battery and it booted just fine. Thanks for the content. You have got a subscriber for life and will visit your shop.

This is exactly what happened to my 2015 MacBook Pro 15". Thank you for making this video.

I experienced the same on my macbook Pro late 2011, your video saved me a ton of trouble

This was my solution for a Macbook Pro 2015 Retina. Thanks!

Thanks so much for nailing the root cause.

just had the same problem you are absolutely correct

I have a mid 2010 Macbook Pro that i upgraded the RAM and hard drive and the laptop started shutting down periodically so i'm thinking about putting the old hard drive back. Your video makes a lot of sense.

Amazing. Thank you!

Thanks for this! My late 2013 MacBook Pro retina 13" was stuck in a boot loop, and replacing the old battery completely fixed it. I suppose only apple knows why they are designed to fail this way…

Thank you for this video just fixed this exact issue with a battery swap.

I had the same problem with my macbookpro 15 inch early 2011. I changed the battery and now work perfectly!

I had the same problem, thanks a lot

Great work boss...

thank you so much for this video just ran into this today this is great

Thank you sir for putting out this information ❤

Wow, thanks so much for this ! My mid 2012 A1398 MacBook Pro is doing the exact same thing ! My battery needs to be replaced as it doesn't power on the mac. I have a new battery coming tomorrow. Will post back here we results. Funny thing is that it boots into safe mode. My guess is when the MacBook switches over to the Nvidia graphics card, more power is needed causing the system to reboot since there is no/defective battery.

literally the exact EXACT same scenario with my 2015 Macbook. Bloated battery. it has done a continuous bootloop. I have spent money on new drives and charger and to no avail, it wouldn't work. I had thought maybe that it was my battery, but i thought, surely not, because I have the power cable connected to it. This answers my question/concern if it was the bad battery causing the bootloop. Thank you for making this video.

Thank you 😊

Awesome video man! Thank you so much! I have the same problem with A1989 macbook pro . I change the battery and come back to you !

Thanks for this video! this is the only video on YT showing this issue, and I thought this could be the solution for my MBP Mid 2017... I've checked the battery and some of them got inflate, so I decided to mount a new battery from aftermarket, but even with a new one I still have the problem... I think is useless to go to Apple only to be told the problem is the logic board...

Thanks!! Same here. MBP 13" early 2015. With the battery disconnected it boots

Same problem on same modell. I will go to apple and change battery. THANKS for your knowledge🙏

Thanks for the video Alex. I have a few Apple MBPs and iPads and in general, I love them. As soon as I heard that you had a boot-loop problem, it reminded me of a similar boot-loop problem I had with an early iPad. Not sure where I got this information (it could have been from the 9th Dimention...lol) but after researching a bit, I discovered that the boot-loop could be fixed by changing the battery on the ipad. Whether this situation has been created by design or not, I don't know. Cheers

I had the same problem with my 2011 Macbook Pro. I just needed to remove and replace the battery and then it worked perfectly again.

very nice, good job

Same thing happened to my 2015 macbook air. Thanks for your video

Same here MacBook 15 Retina Mid 2015, battery will be arriving next week.

Tanks , same problem Macbook Air 2015!

Great Video! Just fixed one that was looping by installing a working battery just like you said everything was fine except the battery Thank you! ohh and just subscribed to your channel

Thanks a lot .from Pakistan 🇵🇰

Awesome!!!

Will look into this

This is happening to me now with the 16" MacBook Pro I bought two days ago. At that price point, there are a lot of options, but ironically, the battery performance is what tipped my decision toward the MacBook. Well, now what?

You are my tutor, my friend

Wasn’t my battery in the end. I have 2011 mbp that was stuck in boot loop. I opted for the software fix that bypasses the main gpu and only uses the intel gpu chip. Works fine now for about a year and all is well.

Whew! Thanks.

Thank you for saving me hundreds (if not thousands) of dollars

Common problem with this model. Nice video

Thanks

Hi! I experienced the same issue on my Macbook Pro 15” A1398 mid 2013. Suddenly the started endless loops, starting, chime sound and restarting after a few seconds. I tried for several weeks to figure what’s the issu, finally I noticed the battery was bad(there was a visible oxidation on the electron board of the battery). After replacing the batteri it works fine now..

Your vid fix my problem, thanks😭😭😭

which reference of the flow that you use friend you a great professional can me to pass I am from Brazil and I accompany your channel in RU-vid my name is Wilton

Thank you so much. My macbook 2015 15’ has a battery problem. Then when the battery dies, it starts booting like this. Now I’m changing my battery and I’ll get it back later this week 😊

My 15 inch mid 2015 macbook pro does have liquid "damage", but EVERYTHING was working perfectly except for the battery. I know for sure because for a long time I could turn it on and use it with the power connected. Then one day it started doing the boot loop out of the blue. In a few days I am replacing the battery and will see if that works. Keyboard, fans, memory, speakers, everything else is working fine.

I have exactly the same problem with the 2013 macbook pro, only I turned off the battery by plugging in the power cable and the macbook boots up without a cyclic reboot. Thank you for your advice

hello sir, does the problem persist with the 2019 15 inch MacBook Pro?

Im having the same issue with my Mac-mini but obviously there is no internal battery like in the macbook. The strange thing is that I got it to power up normally after restoring from a time machine backup but after leaving the computer on for a while I came back to a black screen and the fan running constantly. Any help would be greatly appreciated

Macbook Pro mid 2015, already replaced the battery (new and working well) but after the latest update on Catalina, a boot loop happens but the screen also flickers/screen change color randomly and does not boot correctly when flickering/different color but after it reboots with the correct black background screen it can boot correctly. The next time you use it and boot it up, it will go the same process again and wait for it to get the correct background after having several random screen flicking and changes in screen colors - 30 minutes to 1 hour it will do that way. When it boots correctly, it is usable like any computer as if nothing happens. Booting to recovery hoping to reinstall it will only give a circle with diagonal line like a no entry sign. Booting with Linux as it is dual boot will also go to the same process of random flicking/different screen colors (before the OS is even loaded) until it reboots to a normal working color and screen behavior then it can boot correctly but it also have this correct color and no flickering before the operating system can take over but cannot continue to work even when the operating system is already up, screen goes blank that you have no control at all other than you have to power it down and power it up again. If I do not turn it off while (whole day or more) at working state, it will work just fine the whole time. I suspect something related to Catalina is not working well as the last update have something to do with graphics for new models. There are times it can boot in Catalina but you can only run one program, running another program will cause the programs non responsive, you can force quit each program but you can no longer lunch anything until only the mouse pointer is the only thing you can control. I am still using the Macbook Pro mid 2015 (bought in December 2015) posting this message and on Linux but I have to wait for that right moment it can boot correctly. No heating issue. No performance issue other than when you power it up to use it that you have to wait a long series of boot loops. Battery was replaced already twice as replacement can only last a year and bloats again.

Yeah think different. The 2013 runs with or without the battery but the 2015 has different power sensors on the board so if the logic board sensors are not seeing a certain amount of Amps it will shut it down. And at that point it just retry's to boot

You confirmed what I suspected but I'm an IT engineer who works on various brand servers daily so can imagine how much time would be wasted troubleshooting this one by many.

Hi Northbridge , thanks for the video , I am having a 820-00168 and no schematics or boardview so I spent 3 days on this problem it was driving me crazy . No liquid damage or drop and still bootloop , the only difference is mine is bootlooping even when the battery is disconected and I sometimes get some white textlines instead of the apple ... the power supply is going crazy as well , from 0.200 A to 1.6 A and switching all the time up and down....I am afraid I have to give up soon .... The weird thing is when the board is out of the case its working and it is stable on 0.8 A... any ideas ? :)

I have the exact same problem with the bad battery that does not charge. I have ordered a battery and I hope that fixes it.

I am currently going through a similar problem with my iMac desktop. Would the problem be something similar to this? The model year is 2014 or 2015.

it already happens with me and my conclution is you can use the combuter without battery if you have original magsafe 2 85w ;)

Same problem, A1502 early 2015

I have both 2015 15" and 2012 13" and both got the same problem. It all started after the replace battery now came up.

I have a question I have a 2007,8 or 9 not sure but for some reason it just turns on ok but when it finishes booting it showed up a bunch of codes and shuts off

I have same model A1398 Macbook Pro Retina 15" 2015 model and battery model is A1618. I am facing same boot loop as my battery is all swollen and wasted. After the battery died I am not able to login to my mac. I had Windows installed from boot camp and it reboots after I enter password in both Mac as well as Windows. Even, I tried removing battery, still same. Once in a while I can login to the OS successfully, but it reboots automatically after some unfixed duration. I will try to replace the battery. This was really helpful. Thanks. I thought my logic board is having some issue. But, you saved the day. At least I have hopes with my Mac and save 50K INR :)

Thanks a lot finally after 6 month of not being able to use my mid 2015 macbook pro now i know how to fix it

I am having the same issue with my 15 inch macbook pro 2014. I ran the diagnostic test and it tells me that my battery is bad too!

2011 early MacBook Pro here. Issue just started out of nowhere. Gets to grey Apple logo. Three quarters on the progress bar, then blank grey or black screen then reboot or off. I will try a new battery and report back. Can’t boot from second drive or anything at all. Apple remote diagnostics no hardware or software issues. Battery was due to be replaced. Will also try with battery disconnected. Fingers crossed!

First, this is a great video! Now, I replaced my battery because it was distended. The replacement went well but when I login to my computer it loads the desktop then reboots. It's weird because it doesn't reboot when I just let it sit at the login screen. I did a search hoping to find a solution and your video came up. No luck I guess because these symptoms are not identical to mine. Still a great video, sir! Thank you!

Same issue here. My battery was inflated so I ordered a new one, replaced it then the laptop was working except the trackpad and keyboard. I figured the ribbon cable was damaged, ordered a new one then everything was working except the battery wasn't charging and showing up in MacOs. I ordered a new one, then the boot loop issue showed up. After seeing your video, I assume this battery is also defective, I'll try a new one hoping the third will resolve the problem. Thanks for the tip..

I suspected this.. I have a 2015 macbook 13"..stuck atm. So I need to find out what battery and see if I manage to replace it then. Thanks

I came across your vidéo because I’m facing the same problem right now and I was looking for solutions. Don’t know how to thank you, before coming here I opened my mid 2015 MacBook Pro and cleaned everything and every part in it thinking maybe it’s dust or something similar. I’ll just shop another battery and replace it, thanks a lot. Now I do know Apple don’t sell spare parts as other manufacturers; so my question is do I need the serial number and/or model number of my MBP15 to buy the new battery or I can just go to a shop and ask for the battery of MBP15 in general ?

Thanks a lot, I have MacBook with the same problem, and they remove the battery and every time that I try to install macOS, it tries to boot but then turns off. The weird is that I was able to install windows 10 and it works properly, but if I try to install macOS the problem comes back. Thanks for the video !

thanks i will try to change battery i will update all of you here guys...

my iMac is having this same hustle, please what do you think is the possible cause, because iMac doesn't use battery

Same thing happened with my early 2011. Battery was the culprit.

Holy s.... Same problem right now :// It seems it's not only the 2015 model

I have a 2012 MacBook air and it loads and then turn off. So it might be the battery too but idk for sure

Thanks for saving me from three hours of banging my head against a wall. I have this exact model with the same issue. Other MacBooks can run without battery but not this one for some reason. Annoying.

I have the same problem, but with my MacBook Air 2020 13 inch. Will changing the battery solve the problem for my MacBook too? I have no liquid damage, never spilled anything on it but I noticed in the last few weeks the vans made a lot of sound. After doing a reset, SMC And PRAM the laptop got stuck on a reboot loop and even an internet recovery won’t work. I tried everything. Could you please advice?

my macbook pro late 2013 has the same issue it restarts randomly .. is it the battery thats causing it?

So, I have a 13" 2015 macbook pro, same issue exactly. I replaced the battery, but still same problem. When battery is unplugged, it works, but is slow. Seems to be a logic board issue, what part should be investigated?

Hello. My issue is kind of similar. I have a 2012 MacBook Pro I believe. The issue occurs at the login screen. When I click on my profile, it automatically restarts. Do you think this is also from the battery? Please let me know.

I have 2 Macbbok Pro 15" (both 16 GB, one with 521GB Hard drive and one with 1 TB hard drive) and both have exactly the same problem. I also have a 2013 Model - which my wife uses - without battery that works very well (directly plugged in all the time) - but my Late 2015 15" MacBook Pros' don't work and exactly behaves like you described.

i have a 2017 A1708 from a friend and about to replace the battery as well...theres times where it shows a low battery screen even though it is charged

Is there any way to simulate that a battery is plugged in with an old exploded battery? and Work only with the Charge cable

My 2011 is doing it too

I have to get a new battery? I have a MacBook Pro early 2011 15in will it work?

I have the same e problem with my iPhone 8plus

hello I have a problem on the mem iMac 2012 slim.imacu when you turn on the button starts loading the system it stops in three quarters and stands and never runs to the end after a long time the HDD is turned off and the cabling is fine. It can be GPU thank you for the advice

Hey, I have a desktop that recently has a similar boot loop where the desktop keeps restarting, took it in and was told I had a dead CPU, I replaced it but still had the same problem, I have tired searching and want to know what it could be. if you can answer would be amazing thanks :)

well the 2015 has a completely different trackpad, its the force touch (I think thats what its called, but it has more in common with 2016 and up than prior). all 2016 and up MacBooks won't start if battery has failed, and that seems to be a common theme for apple portable devices, you MUST have a good working battery for computer to work properly.

I'm guessing it has something to do with GPU requiring a lot of power. So much power it can't get it from the power adapter alone. I've seen other electronic devices that won't work without a battery plugged in.

I have fixed my boot loop on my 15" 2016 MBP. Start the laptop, hold down CMD + R (for Recovery Mode) Click on Install new System My account and all my data is still there. I don't know what caused it but you should try this out before deleting something.

I have this problem (boot loop) on my mid 2015 MacBook Pro w/retina. Prior to the boot loop issue, I had just swapped out a bad (swollen) battery & trackpad w/ flex cable. Laptop worked fine for about 2-3 weeks. Then, after a minor drop...the boot loop started. The drop was no more than 18 inches- 2ft (off office chair seat onto a padded laminate floor) and suffered no physical damage that could be detected. Immediately after the fall I turned it on was able to boot up to the user’s log in but, eventually it went into boot loop. I noticed during the boot loop the heatsink would get too hot to touch. I also noticed if the charger would disconnect at the magsafe, it would automatically “restart” the boot loop...like it powered off then on again. Any ideas on that scenario?

How about when you power on the apple logo appear and then thr display white is appear also then restar again its the same things always restarting.

I have same issue with mbp m1 16gb frustrating reboot loop is just insane

I’m having that problem now. I need to find a battery now. Not sure where to find one
