Unresponsive keyboard and trackpad on pre-installed yosemite macbook pro mid-2014

Hi,
I have a brand new MacBook Pro (Retina, 15-inch, Mid 2014). Shipped with Yosemite pre-installed, the version I have is 10.10.1 . I don't have any software installed except Google Chrome, so it is clean/new OS.
I noticed sometimes the keyboard and trackpad become completely unresponsive after waking up the laptop from sleep. Happened several times, the last time it happened I could not reset PRAM or SMC as keyboard was unresponsive even after restarting or shutting down so I had to Re-Install OS.
Right now I have the laptop next to me, again the keyboard and trackpad are unresponsive after wakeup from sleep, and I did SMC reset but did not work. Trying to reset PRAM or go into Recovery mode .. etc, it is not responding to the keyboard, as it is unresponsive at that point as well.
What should I do ? How can I tell if it is Hardware or Software problem ? I ran the apple test diagnostics test and there was no problem reported. And I am not able to install Mavericks because it is shipped with Yosemite pre-installed so it is not allowing me to downgrade.
thoughts ?

I just noticed that I have the following in the system log, both keyboard and trackpad are completely unresponsive even when shutting down/restart/sleep. I cannot even reset PRAM.
This keeps showing up in the log, not sure what it means.

I want to re-install my Pre-Installed Lion Macbook Pro, but I can't get the Lion OS from App Store with my Apple ID. Please help, thanks!

Hi, I want to do a clean re-installation of my end 2011 Macbook Pro which comes with pre-installed Lion OS. I go through the installation steps and after App Store verified my Apple ID, it prompted me that I did not purchase the Lion OS. I am very surprise to see this message which my pre-installed Lion Macbook Pro should have it. Please help and advise how can I get the OS? All other bundle softwares were in the purchase record except the Lion OS.

That was my mistake - sorry - it IS Command-R to boot to the Recovery disk, not Command-D: I either just hit the wrong key or am just now coming awake from my nap.
Let me see if I can just explain it in a few steps - I don't know of any link (but it would make a good User Tip):
Create an up-to-the minute back-up of your internal hard drive using an external hard drive and Time Machine.
Boot to your recovery partion - holding down Command-R on boot.
Use Disk Utility to erase Macintosh HD - use one GUID partition and format as "Mac OS Extended (Journaled)". Unless you're selling the machine, there's no need to do a secure erase (which can take hours).
After you erase the disk, re-install Lion from the same Recovery partition.
After installation is complete, reboot, again holding down the Command-R keys to boot into the Recovery Partition.
Restore your Time Machine back-up. This could take several hours.
Reboot after restore and you're back in business.
That should take care of everything - all you need is an Internet connection.
Call back if I didn't explain things too well - at least I got the Command-R right this time!

MacBook Pro Mid 2014 shut off randomly and won't turn back on.

Hello,
My MacBook Pro(Mid 2014) won't turn back on. I was just typing up my essay and it just turned straight off and won't turn back on. It has happen several times before and all I had to do was press the buttons(SMC method) and the PVRAM thing and it would turn back on. But now it doesn't turn on at all. How do I fix this issue? I had went today to the Apple Store and had a appointment at 3:15-3:25 and I was late by 2 minutes, so they couldn't help me and offered me to come back at 5PM, but will busy so I asked for 5 Monday. Does anyone know what the problem might be? Back when it was operating it would shut off whenever I was using it at the random times. This is my first MacBook so I don't know if it's suppose to get Hot and loud sometimes when operating and then cool off afterwards if that helps out. It shutoff last week wednesday and doesn't turn on at all, but will charge to fully green though. Anyone got any suggestions? I do have a MacBook screwdriver to open it, so if anyone knows anything about the inside and how to resolve the issue it would be great. I don't know how to remove the battery so if you do know please tell me or some keyboard trick would be helpful! All my data is on this so I would like to solve before Apple erases my data.

What software do I need to install to play some games MacBook Pro Mid 2014

Hello, what software do I need to install to play some games - MacBook Pro Mid 2014. Games like : Alan Wake, Assassin's Creed, Boarderlands 2, FarCry series, Crysis, etc.

Assassin’s creed II and Borderlands 2 are in the Mac App Store.
The other’s don’t appear to be ported to OS X. You’d have to install Windows in one of the various ways, Bootcamp (native boot) or Virtualization (VMWare, Parallels, VirtualBox). Games under Virtualization probably don’t run well.
Also, see here http://paulthetall.com/far-cry-mac/

Tried installing all the drivers that people recommended from Realtek, nVidia and nothing has help me fixed the problem. is there a way that i could fix those problems?

Look in the Boot Camp system requirements located here: http://support.apple.com/kb/HT5634
Find your computer model and year. I think you will find that you should be using version 4 of the Windows support software.

I was installing soundflower macbook pro mid 2011/Snow leopard Grey loading screen

Hello i was installing soundflower for my macbook pro mid 2011/Snow leopard. However when finishing the installation for soundflower and click restart computer my mac now has a grey screen with a loading bar that doesn't finish. I already try safe mode and it doesn't work. Is there a way to disable sound flower installation?

No. You use "C" to boot from the optical drive
Hold down the Option key to select a different disk drive to boot from
When it comes up with all the disk that have an operating system on them, select the one with the bootable clone on it

Can intel 520 series SSD be installed in macbook pro mid 2009

This is some of the information for the 180g SSD I want to replace my HD in my 13" macbook pro mid 2009
25nm NAND Flash Memory
2.5” form factor
SATA 6.0 Gb/s performance
My computer though has this information for its hard drive:
Product:          MCP79 AHCI
Link Speed:          3 Gigabit
Negotiated Link Speed:          1.5 Gigabit
Description:          AHCI Version 1.20 Supported
I know that the SATA 6.0 will be backwards compatible with my connection, but I was wondering if I am going to hit any problems. I am going to do a full time machine backup so I can have everything cloned onto the SSD, but want to know before I buy the SSD

Recently installed same type of SSD (Intel 520 120GB) in our 2010 Macbook (white) and runs just as well as its big bro. No problems at all. Storage isn't an issue since most stuff's in the cloud these days and we carry large files around on a USB stick. Way to go!

Unresponsive keyboard and trackpad

Hi, for a week since installing OS Lion on 2007 MacBook, there is no keyboaerd and trackpad. Anyone has same problem and solution? Do not event know whether it's hardware or software issue.
Thanks

No Doh!
After three repeats of this input device problem I called apple support, went through all their suggestions until they agreed that this is a hardware problem. They will replace my refurbished 15 inch AlBook.

OS X Lion Pre-installed on MacBook Pro?

If I buy a new Macbook Pro today, will it come pre-installed with OS X Lion? If not, when will it?

If you've purchased a qualifying computer that does not include OS X Lion, you can upgrade to Lion free of charge. And if you recently purchased a qualifying Mac Server, you can upgrade to Lion Server at no additional cost. Check out the conditions below to see if you qualify.

Is Snow Leopard now pre-installed onto MacBook Pros?

I'm going to buy a MacBook Pro, but I'm wondering about the installation of Lion. If I buy a MacBook Pro now, will I have to download Snow Leopard AND Lion?

It will only have Snow Leopard installed. But you will be able to get Lion for free when it is released. See:
The Mac OS X Lion Up-To-Date upgrade is available at no additional charge via the Mac App Store to all customers who purchased a qualifying new Mac system from Apple or an Apple Authorized Reseller on or after June 6, 2011. Users must request their Up-To-Date upgrade within 30 days of purchase of their Mac computer. Customers who purchase a qualifying Mac between June 6, 2011 and the date when Lion is available in the Mac App Store will have 30 days from Lion’s official release date to make a request.

I bought a brand new MacBook Pro Mid 2014, and my battery cycle count is on 2!!

As I said on the question, a brand new MacBook Pro I bought recently which I haven't even put on charge yet already has a cycle count of 2!
I'm just curious if this is normal and I want to make sure that I received a brand "new" one not a refurbished one.
Did anyone else order a new laptop and have cycle charge of 2 or more and is this normal or not?

The factory charges the battery, one cycle, they may then test that particular MacBook Pro as part of the production testing and it ends up with another cycle. Two cycles is not something to worry about. If you bought the unit from an Apple store or directly from Apple, it will not be a refurbished MBPr unless they specifically said it was. They don't do things like that.

Unresponsive Keyboard and Trackpad problem AT STARTUP + Sleep problem

When I turn on my computer it boots the OS and everything works except for the trackpad and the keyboard. I wait for about 5-7 minutes and then the trackpad and the keyboard start working.
Additional problems:
If I try to sleep my computer, the screen turns off, but the computer never stops working, so I have to force it to shut down.
Temporal Solutions
1) Boot in safe mode, it solves the trackpad/keyboard problems but not the Sleeping problem
Attempted fixes
1) Conencted external keyboard mouse/keyboard. Doesn't work
2) Reset the battery controller.
3) Reinstalled 10.6
4) Installed 10.5
5) Installed 10.6.3
Known Stuff:
1) The trackpad/keyboard are always connected as I can move the mouse and use some gestures with the Better Touch Tool app, and the keyboard works because if I click the Caps Lock key, the small led turns on.
2) Also, I have the HardwareGrowler app which tells me if hardware gets connected or disconnected and it never tells me anything about the trackpad/keyboard getting disconnected.
3) The OS is working at startup because apps show stuff and get updated and I can still get growl notifications.
NOTE: This is an intermittent problem, about 1 out of 10 times I turn on the computer I GET the problem.
Thanks a lot!

I came across a similar issue as the original poster. My trackpad and keyboard are unresponsive for 5 - 7 minutes after startup. I've updated my OS to 10.6.4 twice and it's still happening. I recognized this behavior after the Preferences->Network pane froze while I was trying to remove a VPN setting. Removing /Library/Preferences/SystemConfigurations did not help the problem.
Do any of you have advice on debugging the issue?

Macbook Pro Mid 2014 Hard Freezes and Crashes

So I bought my Macbook about a month ago, and ever since then Ive been having this same issue over and over again. I have tried every solution apple has thrown at me and nothing has seemed to fix it. I have sent it out for a repair, reinstalled the OSX, Cleared the pRam, and various other things. I have not narrowed down the situation myself and cant seem to figure out what is causing these hard freezes and crashes. It always happens randomly at something GPU related it seems. Almost like the video card gets to stressed out at crashes. From scrolling up the page of a website to switching to a different video on youtube, all these little and sometimes big things have caused it to crash. Apple has sent it out for repair and they claimed that they fixed the logic board, but that didn't work because the issue still persists. I have reinstalled the OSX from guidance of a apple care associate over the phone. Ive eliminated almost every possible situation they have given me and nothing seems to fix it. Im not sure if there is a defect in these particular models or I just got a lemon but either way its frustrating. I will post the specs below and provide any other info that is asked.
SPECS:
GPU: Intel Iris Pro
Processor : 2.2 GHz Intel Core i7
Software: OS X 10.9.4
RAM: 16 GB 1600 MHz DDR3

Problem with bluetooth connection between iPhone 5s iOS 8.1.2 and MacBook Pro (Mid 2012) Yosemite 10.10.1

After the upgrade to iOS 8.1.2 in iPhone 5s and OS X 10.1.1 Yosemite (MacBook Pro Mid 2012) can not connect my iPhone 5s to the MacBook, the iPhone tells me: "The MacBook is incompatible" or the message "Connection Error, Make sure the Mac is turned on and is within range" even the iPhone being close to the Mac. Otherwise with the updated iPad 2 (iOS 8.1.2) is connected via bluetooth to the MacBook without any problems, Even the iPad 2 does not detect the iPhone bluetooth.
Help me please

An iPhone will not pair via Bluetooth to a computer (Mac or Windows) except for personal hotspot and then only if your cellular plan supports it. https://discussions.apple.com/docs/DOC-7722
If you are attempting to use Handoff/Continuity, that does involve Bluetooth but the devices are NOT paired; Bluetooth just needs to be on and the devices in range of each other. The following may help with Handoff/Continuity issues: http://support.apple.com/kb/TS5458

Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

I have a Mid 2011 Macbook Air.
Upgraded to Yosemite last week.
Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
Thanks,
John

Hi!
I have exactly the same problem, and I can't find any solution.
I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
Any suggestion is greatly appreciated!
