HT201255 MacBookPro Early 2011 updated to Yosemite will no longer boot.

Hi All,
I had a Mac issue a few months ago where it started to work very slow, lagging, the turning ball kept appearing.
I backed up what I needed therefore, I care less about the data.
Since then, at some point I wanted to encrypt it but I believe I might have done something to it with an interruption. In any case it kept working and that bar started appearing bellow the apple logo.
Shortly after -> completely unbootable.
My troubleshoot so far:
1. Reboot -> nothing
2. Single user mode -> ran the shown commands and said the Drive is OK -> rebooted -> nothing.
3. Ran in verbose mode, saw several errors:
BUG in process suhel[perd[136 (and 139)]: over released legcay external boost assertions (1 total, 1 external, 0 legacy -external)
also saw in the work up of verbose _> error 107 rebuilding /system/library/Caches/com.apple.kext.caches/startup/kernelcache
Also a Warning: couldnt block sleep duringncache update
and Warning: proceeding without DlskArb
Previous shutdown cause -128
DSMOS has arrived
What else did I do:
Tried the AHT -> ran normal test and extensive test -> Both reported that there "are no troubles"
I tried Cmd+R and just R -> a few times I saw the spinning globe asked me for WiFi pw -> no success. Reboots and cant enter any GUI
Tried Safe Mode or Recovery where you have basic functions and DiskUtil -> I cannot even enter.
I have reset the NVRAM etc but no go
I made a Yosemite and Snow Leopard (My original OS) bootable USB Drives and tried booting from them -> it goes to a grey screen and nothing else from the Snow Leo
The Yosemite -> did not even want to boot up. It didnt found it once and then new USB found but not booted.
I believe I havent tried anything else but I am still unable to access my computer.
I do not have the original disks (Cant find them)
Oh, I tried with a Windows installation disk, just to see what might happen -> black screen.
Please, desperately need help. I have a VMWare OSX at the moment and several flash drives I can experiment with.

Previous shutdown cause -128
A negative shutdown code may indicate a hardware problem. The precise meaning of the codes is not publicly documented.
If you haven't already done so, you can try resetting the System Management Controller. Otherwise, or if the reset has no effect, see below.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.

10.4.11 Update failed; Computer will no longer boot

I downloaded the 10.4.11 update through software update on my MacBook Pro. When the installation appeared to have completed, I received a message stating "Installation failed. Please try installing again." After this message, finder froze. Upon using AppleOptionEscape to relaunch finder, finder failed to relaunch at all, something I have never seen before. (no other applications were open at this point). I had to preform a hard shutdown (held the power button down until the computer turned off) in order to power the computer down. Now, when I go to boot up, the screen with the spinning circle (the one made of lines) remains indefinitely. The computer heats up and the fan kicks in, but the computer fails to complete booting.
Any help is great. I know how to and can reinstall the OS, but it would be a pain, so I'm hoping someone will have another solution. Thanks.

If the disk is in the machine, try starting up holding the C key down. Should boot from the install disk and then run Disk Utility from the menu...don't go through the install procedure.
OR you could try booting into safe mode....hold down the shift key while starting.
OR you could boot into single user mode and run fsck (same as repair disk in Disk Utility). Start up holding down the command and S keys, until a scary black screen with white writing appears. When the white writing is complete, type fsck -fy (NB space between k and hyphen) hit enter. when it has done, if it says the file system has been modified do fsck -fy again. when that has finished type exit, then hit enter and it should reboot normally.
If you get running again, repair permissions and run the comb updater
Good luck
Mike

Macbookpro early 2011 keeps saying password invalid for WPA protected wifi

It's been 2 days my macbookpro early 2011 with lion os x 10.7.2 can't connect to wifi.The wireless connection drops and when i try to reconnect,it requires me to retype the password but after i type the password,it says connection failed although the password i type is correct.i try to use assist me and assistant to connect but it shows password is invalid.i try to add a new location and readd the network name but still fails to connect.Can someone pls help...

Since 10.7.2 on a certain router, I get the same thing. The connection drops, then when reconnecting it asks for the password, then won't take the correct one. I restart and then it usually connects fine. Lion has been one nasty cat since day one. How I miss Snow Leopard.
My iPhone, iPod touch and a friend's MacBook Pro, on Snow Leopard, connect without a problem on the same router.

After installing the most recent iTunes update/version iTunes will no longer run on my PC. I receive a window with the Microsoft error code R6034

After installing the most recent iTunes update/version iTunes will no longer run on my PC (Windows 7). I receive multiple error windows with the Microsoft error code R6034. Microsoft's Help site states that this error occurs when a driver attempts to access the C++ library without a "Manifest". I do not know what a manifest is, but apparently any attempt to directly access the C++ library is not permitted. The site instructs the viewer to contact the application developer.

After installing Leopard, my G4 will no longer boot in OS 9.22. (Classic still works, but I need it to boot in OS 9.) Any clues about what the Leopard installer might have done to my machine that rendered OS 9 boot unusable? What can I do to fix it?

(Classic still works, but I need it to boot in OS 9.)
Any clues about what the Leopard installer might have done to my machine that rendered OS 9 boot unusable? (And what can I do to fix it?)
Details:
G4 Gigabit Ethernet
Boot ROM version: 4.2.8fl
Accelerator card added: 1.6 MHz
1.5 Gig Ram
I have erased the partition that had Leopard installed on it.
I zapped the pram.
In Open Firmware, I "reset-nvram", and then "reset-all"
I tried to reinstall G4 FW Update 4.2.8, but that must be done when booted from OS 9, and of course, that's the problem: it won't boot into 9.
I tried restarting from 9.2.1 DVD.
I tried restarting from an external firewire drive containing OS 9.2.2.
I tried moving a fresh OS 9.2.2 system folder into an empty partition on an internal hard drive. (Partition was created WITH OS 9 drivers installed.)
All attempts to boot into OS 9 give me the same results - grey screen - no spinning beach ball, no icons or logos - just a blank grey screen.
This machine still works fine in OS 10.3 and 10.4, and it worked fine for many years booting into OS 9, until I installed Leopard, and I haven't been able to boot into OS 9 since then, although I have done considerable research online and tried many things.
I have since learned that this machine does not support Leopard - 10.5. Fine, but how did it break 9.2.2?
Any help greatly appreciated.

Thanks for checking in, BDAQua.
Problem solved.
In the docs that came with my Powerlogix accelerator card, I found this sentence buried:
"If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, so you will have to boot from the Firmawre Update CD and perform this process again in order to boot in OS9."
The "process" it's referring to is the process of setting up the NVRAM for booting into OS9 from the CD.
Fortunately, I was able to find the disk, and it worked as expected. I can now, once again boot into OS9.
Conclusion: My (unadvised) attempt to load Leopard on this old machine apparently reset the PRAM on the accelerator card and cleared the NVRAM code for OS9 boot. Although I did attempt to reset the NVRAM via Open Firmware, it did not reset it on the accelerator card.
So, thank you BDAQua, for your "Ah yes" . . . that's all I needed to steer me in the right direction.

881W Will no longer boot with Radio Card installed

Hello!
I have a Cisco 881W that will no longer boot/operate properly if the internal radio card is installed.
If the card is installed, all I get is the following...

If I remove the entire WiFi Radio card (both boards), then It boots fine, cookie appears intact, devs appear, IOS loads, just without the WAP.
Any chance this is a matter of a file getting deleted or corrupted or is this certainly bad hardware? The router sans Wifi appears fully functional.
Thanks!

You should be able to RMA the device. Search the forum for a post on the limited lifetime warranty:). They explain it good there.

MacBookpro Early 2011 graphic issue won't boot

Hello,
My Early 2011 MacBookPro suddenly suffered from graphics issues for a few days then it won't boot at all.
The hardware test says it is ok and my hard drive too. But when I want to boot, the apple appears and the dong too, but then blank screen. It is the same with a bootcamp boot, but with a blue screen with lines all over the screen. The recovery partition doesn't start either. But I can access boot from my hard drive with another Mac on target mode.
Anyway Apple doesn't admit there's a problem a want me to pay the reparation, because they don't report it as a real problem, saying that I damaged the computer. But there are threads here and all over the internet, and they don't want to do anything.
On the phone, the apple guy told me that I had to pay 80$ to see if there is any problem , and " maybe if we see there's a fabrication problem, we'll fix it for free ". Do I have to trust them ? What can I do to ?
Thank you

I have a mbp early 2011 and mountain lion will not download

hi there,
i'm trying to update osx 10.7.4 and it just hangs on "waiting" for hours and does nothing, i went into the purchases section in app store and it says "An error has occured" in red letter, i click teh download button again and it does abosultley nothing.... and ideas would be greatly appreciated ps i have a 15" mbp early 2011 if that helps

Your issue downloading Mountain Lion appears to have been answered HERE. I'm betting you are both running Antivirus.

My Macbook Pro (15" early 2011) got blue screen every i normally booted it. It only can enter the OS when it's in safe boot. Solution please.

My Macbook Pro (15" early 2011, Mountain Lion, but after reinstall i change it to snow leo) got blue screen every i normally booted it. It enter the OS only when it's in safe boot.
I've tried any solution that i got from the internet, such as:
-Reinstalling the OS X (normal install & clean install)
-Reset PRAM and SMC
-Repair Disk Permissions and Repair Disk from Disk Utility (the result is OK. There's no problem)
-Repair Disk Permissions manually (with Command + S at the beginning of booting)
-Checking Hardware from Application Installer DVD (result is OK)
-Checking from Mac Resource Inspector/MRI (result OK)
-Booting from Recovery Disk is same problem, blue screen
All of that solution is not working. My Macbook still got light blue screen and sometimes blue screen with lines after apple logo and spinning wheel is shown.
HDD is in good condition because when it's checked on the other macbook it can be booted. But if you must know, other HDD can't be booted when its plugged to my macbook (blue screen again). If i do safe booting, it works but can't play video and music also photobooth. I got confused with this case.
Any solution or comment? Thank you very much by the way

Hi. I'm not trying to rush things, you may have a different problem, but your issue looks quite familiar to me. I recently had a problem with the discrete graphics card (the Radeon GPU) due to overheating, all because a faulty application of the thermal compound in the factory.
In my case, the problem started slowly and intermittently, a few days after a gaming session (Quake 3) of about three hours (at the moment, I didn't realized that could be linked to the problem).
This issue is being actively discussed in another threads in this forum, but so far there's enough evidence that it's been causing similar problems for 2011 MBPs owners: screen corruption, black/blue screens, and in some cases, a total inability to boot. Some of the threads I'm talking about:
https://discussions.apple.com/message/13150366#13150366
https://discussions.apple.com/message/21110132#21110132
So far, and since the problem seems to affect only the discrete GPU (that's why you can boot in safe mode) a possible solution is to disable it by removing some extensions which prevent OS X from loading the Radeon drivers. This post describing the process (there are different files involved depending of your GPU version, so make sure you are moving the right ones):
https://discussions.apple.com/message/22521574#22521574
In the case your discrete GPU survived and is not permanently damaged, I personally had success by changing the thermal compound myself, which completely fixed the problem (at least for now). I've posted about it here:
https://discussions.apple.com/message/22630561#22630561
I hope you can find a solution, believe me I know the feeling when you see your expensive machine turning into a brick and it *****.
Good luck!

IPad2 update to iOS6 will no longer play UTube: All my favourites that were previously viewed and saved with my iPad2 will no longer play. They can't be played via Safari either SOLUTION PLEASE (buy iPad3 which solves the issue isn't an option)

IPad2 has been updated to iOS6 and will no longer play UTube favourites. These are favourites that have been previously viewed on iPad2 therefore I know the device is capable of playing them. This upgrade is no longer allowing me to use the device for the reason I bought it.
Apple, I'm feeling as though I've been conned.
My mates iPad3 on iOS6 plays all the stuff my 2 will no longer play.
UTube via safari won't play them, all Apps I've tried have the same problem, a red band stating this video can't be played on your device OR flash player required. Has anyone got a solution???? Please don't write stating you have the same problem, I just want solutions. Thanks

How do I fix my 3gs after 6.1.3 update? It will no longer send / receive group messages and won't send pic text messages either.

Ever since I updated my 3gs (on ATT) to 6.1.3, it will no longer send or receive group texts, and it won't send picture messages
(though I seem to be able to receive picture texts). I've looked around on the boards, and here's what I've tried so far (to no avail):
1. Tried simply turning off / on
2. Tried hard reset
3. Tried having imessages off
4. Turned group messaging off / on (tried while it was off)
5. Turned off all messaging, turned phone off / on, turned all message settings back on
6. Reset network settings
Help! Argghh!!! I never had this much trouble when my previous phone was jailbroken! Here I am, trying to be good!

Thanks, Nick. Calling ATT is a last resort; it's a software issue, I'm sure, and I've also found other
people having the same issue, but none of the fixes work. I reset all my settings: nothing. I'm not sure what you mean by restrictions.

Windows 7 will not long boot after updates

I was running window 7 (64bit) on my Mac switched it off (14th April 2011) last night and it applied 11 updates,this morning it no longer works I get to the partition selection screen and it freezes. Any one know how to repair it if I can't access the windows side ?

When the message came up saying that this version of windows was incompatible... I tried 'cancel'. It moved on. It was in the middle of step 3 of 4 on the upgrade. It appears to be ok now. I'll let you know if I have any more trouble.

My iMac will no longer boot after half installing Maverick (only the essentials package was opened). How can I reboot it back to 10.8.5?

I was able to get a copy of OS X 10.9, but it wasn't the one straight from the App Store (which is free and I wish I knew before I got this other copy, but oh well). There is nothing wrong with the copy, it just simply doesn't initiate the install when you double click on it.
I installed one of the packages (essentials) off file, but not all the rest of them. For some reason the other packages weren't opening because it wasn't accepting my password, so I restarted the computer to see if that would make anything better.
It didn't. It now boots to the grey apple screen and stays stuck loading. I assume because only some of the install disk was installed, it doesn't really know what to do. But how do I fix this? How do I unistall the essentials package so that it goes back to normal?
I tried booting it whilst holding down "Command+Option+P+R" and it takes me to a limbo area where you can access disk utility. Within disk utility I can see that everything is still there.
What is the process to get it back to normal (I previously had 10.8.5).
Please help!

Thanks for checking in, BDAQua.
