How to fix MBPr (late 2013) slowdown due to defective battery w/o replacing it?

Hi,
I have this late 2013, MBP retina 13" running OS X 10.10.2 which has a defective battery (with 'replace now' warning).
The computer is always connected to the charger (since the battery doesn't hold the charge) and I have started to notice extreme lags while doing day to day stuffs (like web surfing, word processing).
I understand its solely due to the battery issue and some have successfully fixed it with several ways
1. Go to About this mac under the apple in the upper left and click on More info
2. Click on system report
3. make a note of what it says after Model Identifier
4. go to your master drive – System -Library – Extensions – IOPlatformPluginFamily.kext -Contents – Plugins – ACPI_SMC_PlatformPlugin.kext – Contents – Resources – find the name from step 3 and move it to a folder that you can find again if needed.
3. Restart and you’re done
However the above method doesn't seem to work since I can't find relevant file for late 2013 MBPr.
Would be grateful if someone can offer me a fix until I get my battery replaced.
Thanks

The problem you face is that a failed battery can expand and DAMAGE the MBP. At the very least you should take the battery out of the MBP (which will require Pentalobe and Triwing drivers) or better yet, have it replaced. Trying to disable it internally does not solve your problem.
Ciao.

New mbpr late 2013 2.6GHz

Hi there
I just bought a new mbpr late 2013 15" yesterday.
The battery is fully loaded but only has power for 3 hours and 15 minutes?
And the display brightness is very low..
Running OSX Mavericks, my old mbp 2008 has a better battery life time....
Any suggestions on this?

I have the same model.
There have been reports of incorrect estimated battery time remaining under Mavericks. Also, if you are performing GPU/CPU intensive tasks on battery power, these reports would be close to expected (Handbrake for encoding, gaming, etc).
Increase the display brightness under System Preferences > Displays
Reset the SMC in regards to the first issue:

How often can i overwrite a SSD (MBPr late 2013 Haswell)

Hello,
do here someone know how many times the SSD's from the new Haswell MBPr late 2013 can be overwrite? I mean the 512 GB Model.
Do here someone have more informations about the SSD? I have reed that it comes from Samsung but i dont know witch technologi here works?
Can a sector here overwrite 1000/3000 or 10000 times.....??
Thank you very much.
Bye

Are you SURE that you want to replace the hard drive rather than just add an SSD? If so OWC sells 3.5 to 2.5 spacers. EveryMac says this about your model *This model has a Serial ATA (6 Gb/s) connector for a hard drive as well as a proprietary PCIe connector for an SSD. As reported by site sponsor OWC, if the SSD is not installed at the time of purchase, the connector still is present and later professional or self-installation is possible.

Problems installing Windows8.1 on High Performance MBPr late 2013 running Mavericks.

Hi, im currently new to MacOSX ( i made the jump from PCs) and although i think the overall experience on MacOSX is perfect i still need to run Windows natively on my mac ( i dont trust virtualisation programs.) and then i started to investigate how to setup bootcamp to "load" Windows 8.1 but im having some troubles with the process ..
1- when i open bootcamp it ask me where is the ISO. file (where the OS is), so i select my Windows 8.1 installation that my brother gave me and he told me that the ISO. have both forms of installations ( the 32 and 64bits) so when i load it on bootcamp it doesnt recognise the existence of the 64bit installation..
right now thats the only problem ( so far ) that im having with this, if somebody can give me some tutorial to install windows 8.1 will be really appreciated.
regards.
DanAtaD

Im downloading windows from this link http://www.123myit.com/downloads/ the 64 bit one, ( idc if its made to be downloaded with intentions of piracy since i have my license key) so illl try running boot camp with that and lets see if that works.
I also have been reading about some problems on the MBPr late 2013 when they try to install windows 8.1 in EFI mode, but they "solve" the problem instaling it on the emulated bios, since its much faster to install it in the efi mode ( better speeds at waking up from sleep, better startup times, etc.) are there any workarounds to this problem or the problem has been solved with a patch from Apple?
thanks.

Having a MBPr late 2013 and having a sound problem the sound does not come tom the headphones even its all the way up and when i remove the headphones it docent come out the internal speaker either ? any idea how i fix this?

the sound do not come out the headphones sometimes altho its all the way up in the setting and when i remove the headphones the sound doesnt come from the internal speaker either and only a reboot fixes the problem and thats annoying! any idea how tto fix this?

Hello. I've been able to play sound without problems through headphones or external speakers to date - the output always switched to these automatically until today. Now, sound output continues through internal speakers even if I plug in headphones or external speakers.
- I tested the headphones and speakers on other devices: they work fine.
- When I plug in headphones or speakers into the audio output port (I have verified that I'm not using the input jack) the devices are not detected and are not listed under the output tab in system preferences-sound.
I concluded from this that I probably had a problem with the audio port, so to test that I tried the following. I plugged a powered multi-USB device with ports for microphone line-in and headphone line-out into the USB port and switched it on. I verified that it was working by plugging a USB stick into the multi-USB device - this was recognised successfully, so the device was clearly working. I then plugged in headphones and speakers into the audio line-out on the multi USB device - but still no sound came through them (and tey were not listed among output devices) and the Mac continued using internal speakers.
What should I do? Does the latter test suggest that the problem does not lie with the audio port, or is my test not conclusive? What would you advise?
Many thanks indeed!

How can Mac Pro (late 2013) create a WiFi network for Mac Books to connect to internet?

I am moving my Mac-Pro (late 2013) to a garden office. I have an ethernet cable to connect it to the house network. I also have a Mac Book Air which will only connect to a network by WiFi. I can use this Mac-Pro to create a WiFi network and the MacBook can talk to the Mac Pro over this WiFi network. But the Mac Book does not see the local network let alone the Internet, both of which are seen on the Mac Pro.
Is there a way that I can connect the created WiFi network to one of the two Ethernet cards in the Mac Pro?
Or what?
Tim

I have half cracked it.
For some reason the first step it to turn internet sharing off.
Then internet sharing can be configured and the wireless network set up and given a password.
Then, and then only, turn internet sharing back on and turn WiFi ON. All this is on the Mac-Pro (late 2013).
Now the Mac Air sees the new network and can log on and connect to the WAN internet locations, at least via Safari.
BUT if I use Finder on the Air, it will connect to the Mac Pro but it will not display what is on its disc. Though I can do screen sharing. Odd.
Also Air-Drop has stopped working, so there is no means of transferring files between the Pro and the Air.
I am going away now for a few days and will revisit this on my return.
Thanks for your help.

Late 2013 13" Macbook Pro Retina Battery Issues

Just got my new MacBook Pro 2 days ago and been using it for web surfing (Safari), few coding projects, skyping and listening to music mainly. Somehow the battery lasts for about 6 hours at it's best and not only that but the battery estimate is not correct at all. I charged it to 84% and it said 12 hours left then at 70% after exactly 54 minutes of battery usage it said 5 hours and 50 minutes left.
The time estimate drops fast and doesn't last that long ... I've seen similar discussions but there problems were because of Chrome or the kernel_task using the memory & CPU extensivley. But in my case, I'm not using Chrome and the kernel_task is taking around 500 - 600 of memory and fair usage of the CPU ..

Hi. I have a same problem with my new MBP 13 RETINA (late2013)
Battery life is BAD! I'm using it without Skype for 2 days, but still, just a web browsing can't kill charge so fast.
How bad is bad? How long is your battery lasting?
What does your Activity Monitor show under the Energy & CPU tabs? There does seem to be an intermittant issue in Mavericks where after coming out of sleep, the kernel_task process will start using ~100% of a CPU forever. This will drain the battery really quickly, and seems to require a reboot to fix. I run iStat menus, and it's pretty obvious in the CPU graph menu when this happens, as the graph shows a constant 25% overall CPU utilization.
When you say you are just web browsing, what are you doing? What browser, and what kind of websites?
A lot of folks on the MacRumors forums are reporting really bad battery life if they use Opera. Try Safari instead.
If you are watching Flash based videos or otherwise visiting Flash heavy websites, that will hurt battery as well. If you can import the videos you want to watch into iTunes they should use much less battery. If you are using Safari and the Flash stuff on the websites is ads or other stuff you don't need to see, install Click 2 Flash to stop it from automatically loading.
Finally, try to keep your screen brightness as low as is comfortable. Half brightness or lower can help.
I get a consistant 10+ hours of battery life using my Late 2013 system all day for browsing with Safari, editing photos with iPhoto & Preview, and creating documents with Pages. I have BlueTooth disabled, and brightness at 1/2 or less.
You can get the statistics on your battery to see if something seems wrong by installing and running the Coconut Battery utility. I'm willing to bet your issue is software and usage related though.

Late 2013 macbook pro showing Service Battery warning after 1 year and 2 months

Hey there,
I purchased a 13" MacBook pro retina late 2013 in December
The battery has recently started showing the "service battery" warning. Here is a screenshot from Coconut Battery:
Surely after only about a year the battery should not be holding only 70% of the charge. Is this level of wear unusual? If I were to take this to an apple store would Apple likely replace it even though it is out of warranty?
Cheers guys.

unfortunately, the batteries warranty is only one year. The only options were the ones they gave you: buy a new battery (which I recommend), or use your mac on the power supply only without the battery.

How much does it cost to replace the late 2013 model Retina Macbook Pro battery?

The page on Apple's website isn't very clear: www.apple.com/batteries/replacements.html
I just bought my first Mac computer ever and I'm loving it -- and the battery life is phenomenal. I'm just worried that in a year it'll be half of what it is now which would not be unlike any other non-Mac laptop, but I really like the battery life this Mac gives.
So I'm wondering, at that point, how much would it cost to have the battery replaced? Does AppleCare include a battery replacement? I know that it's not exactly something I want to replace myself, so how much would it cost to have the Apple Store replace it, if not?

Thanks for the response. I'm worried partially about voiding the warranty if I remove it, and iFixIt's teardown of the latest 2013 Retina model suggests that it may be quite difficult to do without breaking other components...
If they wouldn't do it for free, is $129 the price of a battery, or the price of battery and replacement?

Crazy lags on my MBPr late 2013 with dual graphics

Hello. This is my first MacBook, so I am new to it. It finally arrived to me 2 days ago.
My problem is: every time I start any game, it's FPS is newer higher then 30-35, usually even 15-20. This is very strange, considering this is the most powerful MBPr available. Another problem is that when I minimize a game, OS's UI start to lag like crazy. Once i close a game, everything is fine again.
I tried to turn off "automatic graphics switch", but this doesn't help me at all. My MacBook has 2.6 GHz, 16Gb RAM and 1Tb SSD and NVIDIA GT 750M. This machine should not lag like this.
My Gigabyte P35K never lags even on integrated HD4600 with 2-3 minimized games (i won't even talk about it's descrete GTX 765M), but MacBook simply dies from Diablo 3\WoW\Starcraft\Force Unleashed (which is a funny situation for both Iris Pro and GT 750M).
This is very very bad, because i am an OpenGL developer and Mac's graphics performance is very important for me.
Any help? Thanks!

Is it any differences in battery life between the different processors (MBPr late 2013)?

Is it any differences in battery life between the 2,4GHz i5, the 2,6GHz i5 and the 2,8GHz i7?
I'm planing on buying a macbook pro 13" but I'm a little bit uncertain which processor I should chose. I want as much power as possibly but if it's any significent battery diffrences, then I would chose battery over power. I've read that there is about 45 min diffrence between the 2,3GHz and the 2,6GHz in the 15".

I imagine that there are but since Apple makes no such distinctions, I suspect that the differences are not that great. I have not seen any reports or studies to that effect.
If battery life is of paramount importance to you, consider a Macbook Air. The advertised battery run times are significantly longer than the Macbook Pro.
Ciao.

How I fixed my random shut down from 3rd party battery

So I bought an ebay battery after my original battery died. All went well, and I was in the process of calibrating this battery. As it was charging, it would get held up at 99% (although when I unplugged the power cord, the meter said 100%). After a while, it finally turned green and I was thrilled. Soon after reaching 100% and a green LED light, the computer shut off. I tried to turn it back on but it would shut down again before reaching my login screen, and sometimes after. I plugged in my old battery and used it with the power cord to see if I could find a fix....
I didn't really find anything to help me, so I just left the new battery out, and went to bed.
This morning I took the new battery, held down the button on the bottom ( the power indicator button or whatever) for 15 seconds, put the new battery back in, and started it up. After it started up, I closed the computer and it looked like it shut down again, however, when I opened it back up ( and pressed the power button), it resumed like the battery had been completely drained. After that, the battery started working normal again, and when I close it, wait, and open it, it just resumes as normal.
So, I don't know if this is a permanent fix, but it worked for me.
Anybody have any thoughts?
Thanks.

Hi Bluey
Thank you for your post and offering your help to the users having the same problem. It makes sense, worth to have a try.

My MacBook Pro Retina (late 2013) is daring LOTS of battery while sleeping

Hello
So my macbook's battery started to drain like 30~70% overnight when it was sleeping.
My bluetooth is off, so is power nap.
Programs like 'caffeine' are also off.
I really don't understand why it taking so much battery.
PLEASE HELP ME
(i can't go to a genius because i'm not in the states currently)

Hi there joonkang98,
You may find the troubleshooting steps in the article below helpful.
Mac notebooks: All about batteries
http://support.apple.com/kb/HT1446
There are several common causes battery drain that you can minimize.
Take steps to optimize your battery life per the Optimizing Battery Life section earlier in this article.
A common cause of decreased battery life is a "runaway process." Make sure to check Activity Monitorfor any runaway processes, especially after installing software updates or a new operating system. Installing updates is important to ensure optimal performance for all applications.
If you are still having battery runtime issues after optimizing your computer's performance and checking for runaway processes, test in Safe Mode. Safe Mode limits the active items on the system and allows testing in a more minimal environment. If the battery life is better in Safe Mode, you may need to do further software isolation for the items disabled by Safe Mode to determine what the power draw is while not operating in Safe Mode.

MST Support for MacBook Pro Retina Late 2013 - DisplayPort 1.2 - Will it ever happen? (with sources)

So back in October, I purchased a brand new Macbook Pro Retina (MBPr), fully loaded with top of the line specs. I was soooo excited to have Thunderbolt 2 tech which Intel AND Apple describes as having DisplayPort 1.2a compatibility - which up to this point is unfortunately NOT the case. The point of the information/questions and requests in this article is to engage a conversation about the issues of not having MST support after Apple falsely mislead their consumers to think otherwise - especially when it is clear the MBPr is capable. Please read on...
Apple advertises that the Thunderbolt 2 ports on BOTH the MBPr and the new Mac Pro (NMP) will have 4K Display support with the famed 20gb/sec Ports (DisplayPort 1.2 only requires a little above 17gb/sec). Now that the 10.9.1 update has been released, we have failed to see MST or Multi-Stream Transport enabled on the MBPr Late 2013. Now, as for the New Mac Pro- it DOES have MST enabled in 10.9.1 with the AMD GPUs. For all of you out there that's questioning what this means, short answer is basically the Mac Pro will be able to power a 4K Monitor at 60Hz through the Thunderbolt 2 Port but the New MBPr is stuck with only HDMI 1.4 support which tops out at 4K 30Hz. 30Hz is unacceptable for anything but movies or a photo slideshow. At 30Hz the cursor will jump across the screen, eliminating any of the benefits of 4K.
BUT it gets worse...
Apple can be seen advertising that the new MBPr 15" model can power a 4K monitor THROUGH the Thunderbolt 2 Port here: http://www.apple.com/thunderbolt - This article quotes the following:
"Now with Thunderbolt 2 built into the new Mac Pro and MacBook Pro with Retina display, you can connect the latest 4K desktop displays and get double the bandwidth for your peripherals. And the two generations of Thunderbolt technology are compatible with each other."
Does this not let the consumer assume that the newest MBPr will be able to drive a 4K display through the Thunderbolt 2 Port? I would say yes it does, but at the time I wrote this, the TB2 Ports can't power a 4K display because, as previously stated, MST is disabled in Mavericks for the 15" MBPr Late 2013.
NOW, later on Apple posted the following article on 4K support here: http://support.apple.com/kb/HT6008
4K support on the MacBook Pro (Retina, Late 2013)
MacBook Pro supports 4K displays and Ultra HD TVs at the following resolutions and refresh rates with the built-in HDMI port:
3840 x 2160 at 30 Hz refresh rate
4096 x 2160 at 24 Hz refresh rate (mirroring is not supported at this resolution)
In the article above the New Mac Pro is listed as having support for a 4K Display with the Thunderbolt 2 Port (or MST DisplayPort 1.2a Technology) at 60Hz with no problem. This leads myself and many others to believe that MST will NEVER be enabled on the newest MacBook Pro Retina with Nvidia GPUs. Yes, 4K IS supported but ONLY through the HDMI 1.4 port, which has the limitation of only 30hz. This two-faced advertising is extremely upsetting to a LOT of people, including myself.
Interestingly enough, THIS IS NOT a hardware issue. If one ventures into Windows 8.1 via Bootcamp and connects a 4K Display via the Thunderbolt 2 (or through DP1.2) Port, the Display registers at 60Hz, thus proving that the Thundberbolt 2 Hub Controller is completely capable of MST DisplayPort functionality. Clearly this a driver issue with Apple, Nvidia or Intel or any combination. What Apple has done here is forcing any professional that desires stable and clear 4K technology through their MacBook Pro Retina to do so only using Windows 8.1 on their own machines! Definitely an oxymoron if you ask me...
Later on when the Mac Pro was ready for ordering, Apple placed the Sharp PN-K321 as a compatible option for a 4K Display. On the Store page featuring the (over three thousand dollar) Sharp 4K display, located here http://store.apple.com/us/product/HD971LL/A/sharp-32-pn-k321-4k-ultra-hd-led-mon itor?fnode=53 Apple states the following:
"Note that 4K DisplayPort operation is only compatible with the new Mac Pro (Late 2013)."
All of that being said, and I'm terribly sorry for my wordy ranting...
This brings me to a final two requests to ANYONE reading this post:
a) Has anyone working with the new 10.9.2 Beta Update seen evidence that DisplayPort 1.2 capabilities will be enabled for the new MacBook Pro Retina (Nvidia 750M) with the promised "Graphics Driver Updates" within the next Mavericks update?
and
b) To others that purchased or were/are thinking of purchasing a new MacBook Pro Retina with TB2 Ports: If you are just as upset as me about this crushing blow to consumers that just purchased a $3,000 laptop that were promised something that wasn't delivered - I urge you please, write to Apple and let them know they are making a mistake. You can do this though the support page or through http://www.apple.com/feedback
Thank you for your precious time, and if anyone has anything to contribute to this issue, please jump in....

GOOD NEWS!
The Mavericks 10.9.3 update adds official support for Thunderbolt 2, 4K!
I'm not sure if you will be able to daisy chain anything to the 4K display. I've read that the design of Thunderbolt 2 includes support for DisplayPort 1.2 multi-stream (MST), which allows this type of daisy chaining with 4K, but we don't know if Apple has this supported on it's machines. Apparently it's been buggy in development because the graphics driver needs to work correctly with the Thunderbolt 2 host controller. I'm sure they will work it out if they haven't already.
The above is all via found information on this topic, but you can follow some more discussion here:
http://forums.macrumors.com/showthread.php?t=1713876
One more note on Thunderbolt worth sharing: always keep your fastest peripherals closer to the computer in the chain. If you have a TB1 device directly connected to the computer, anything further down the chain will be limited to TB1 speed/capability regardless of it's native speed. Always connect TB2 devices first, and save anything TB1 for the end of the chain.
