Kernel panic, Yosemite, early 2011 mbp, samsung SSD

I am getting kernel panics about once a day, or once every two days. My system is an early 2011 MacBook Pro, with a new SSD from Samsung (850 Evo). The OS is a clean install of Yosemite from an USB drive.
Everything is running great, except these occasional kernel panics. Does anyone have any ideas?
I'm hoping its not an incompatibility between the Samsung drive - I bought it on the advice of a technician at the Apple store after my original one broke.
In case it means anything to anyone, here is my crash report... help would be much appreciated.
Thanks!

You installed a third-party system modification that includes a kernel extension. It might (or might not) be called "Syphon Virtual Screen." Remove it and see whether the panics stop.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

Kernel Panic on early 2011

Hi,
I have macbook pro 13, early 2011 edition, running OS X Yosemite (10.10.2). I recently updated my 4GB to 8 GB DDR3 Crucial operating memory. Only after a week, today, it started to shut off, in short, sometimes it shut off following with the beeps, sometimes without.. and it never stopped shutting off, I mean, after witching back on, it did the same thing, either 10 minutes later or 15, etc,.
The log says these:
*** Panic Report ***
Panic(CPU 0): Unresponsive processor (this CPU did not acknowledge interrupts) TLB state:0x0....
and
*** Panic Report ***
panic(cpu 0 caller 0xffffff802081a46e): Kernel trap at 0xffffff8020765d4b, type 14=page fault, .....
After installing the operating memory, I also did a security update two days ago. So was not sure which could be the problem. now I changed back to my 4GB op memory and so far it works fine.
If that is the problem of an op. memory, why would it start troubleshooting only one week after??
Is there anything that can be done to solve the problem with 8GB memory? I live in Georgia (country) and to return the operating memory back to US could cost me more than the item itself .
Thanks a lot!

The RAM is faulty or incompatible. You can try cleaning the contacts and reseating it, but most likely there will be no change. I've seen enough reports of problems with Crucial RAM that I wouldn't use it myself.

Kernel panic - trying to install a Samsung 830 ssd

Hi everybody,
please forgive me for my poor English.
I'm trying to install a Samsung 830 ssd with an optibay on my MBP early 2011. The ssd works fine, and I get a Sata 3 speed connection.
The first problem I found was that Disk Utility wasn't able to initialize it! "Posix error: i/o error" or "unable to locate memory".
So I inizitialized it with MacDrive on windows xp on another pc.
Here comes the second problem: when I boot with my ssd on the optibay there's a kernel panic, but when I boot with the superdrive everything is fine. So what can I do? Thanks for your help!
These are the details of the kernel panic

There's an update: I uninstalled Parallels. Then I connected the ssd to my mac with a sata usb cable, and everything worked fine, I initialized it and I tried to copy some files and it was ok..
So I put it into my optibay and booted Osx, this time no Kernel panic!
But now there's a new problem: when I try to copy files or create a folder on the ssd I got error -50 can't complete the operation.. Both with finder and muCommander.
So what shuold I have to do now?
I'm getting a little upset..

Installing Windows 7 on Replacement SSD in optical bay Early 2011 MBP

So i just bought a 120gb SSD and a optical bay enclosure that i installed into my early 2011 MBP. I also bought a optical drive external usb enclosure. I was hoping that I could use bootcamp to install Windows 7 onto the SSD but when i go through the bootcamp menu and my laptop restarts im stuck with a blank black screen. Ive also tried using bootcamp to create a bootable USB (which i had to do a work around to get to work because it supposed to only work for MBA) that didnt work. Can anyone help?

ANYONE???

Which kind of SSD hard discs do support with earlier 2011 MBP ?

Which kind of SSD hard discs do support with earlier 2011 MBP ?
I'm using 15 inch earlier 2011 MBP. I would like to replace hard disc to a new SSD hard disc to improve performance. But I don't know which kind of SSD works fine for it. Does anyone work fine? Could you give me some successful experience? Thanks a lot.
BTW, Can I use SATA3 SSD? And any problems here?
Thanks a lot!

is it a hard questions?

Can't install windows 8.1 on early 2011 MBP

Hey all,
I'm having problems installing Windows 8.1 on my Early 2011 MBP (MacBookPro8,2). When my superdrive died I installed an SSD for the boot drive and kept the original hard drive as a secondary drive. I used BCA (modified to support USB) to create a USB 2 Windows 8.1 install drive from an ISO I previously created. I also had it partition the hard drive. When it reboots I get the "no bootable device found" and blinking cursor issue. I've tried holding down option and choosing EFI, but i've picked up during the last week that installing through EFI on my MacBook Pro isn't possible. Does anyone have any ideas on how to solve this?

I ended up coming across this last night:
http://malwaretips.com/threads/installing-windows-on-a-mac-with-a-damaged-superd rive.32474/
I am in the process of testing this out, but currently I'm stuck with an issue with winclone not expanding the image of the usb install disk to use all the space in the partition. However I did boot into the Windows installer and didn't run into the "couldn't find partition" , "no bootable disk", or "not an MBR" errors I've seen before.
I Think the key for non supported hardware and Windows 8 or later is to create the bootable usb in windows and not through BCA. I actually used the VMWare Fusion trial and a windows 10 technical demo image to do the monkeying around in windows. Hope this helps someone else. I'll keep updating.

Does anyone know if this HD works with a early 2011 MBP?

Looking to upgrade my internal HD on my early 2011 MBP. Before placing the order, would like to get some professional advice.
The HD being considered is:
SAMSUNG Spinpoint M9T ST2000LM003 2TB 5400 RPM 32MB Cache SATA 6.0Gb/s 2.5" Internal Notebook Hard Drive
Thanks in advance for all advice/inputs

Oh, sorry, I didn't note that I am planning on using logic 8 to attempt this. I don't have access to a machine with logic and pro tools installed to try it myself, else I would.

AMD Radeon HD 6750M, Early 2011 MBP, 10.9.4 Problems

Hello,
Ever since 10.9.3 update I have a serious problem with my Early 2011 MBP with AMD Radeon HD 6750M card.
First my configuration:
MBP 2.2 GHz Intel Core i7 (Macbook Pro 8,2)
16 GB RAM
512 GB Sandisk SSD and 750 Stock HDD
AMD Radeon HD 6750M and Intel HD Graphics 3000
OS X 10.9.4
I'm usually using my MBP with external display with a resolution of 1920x1080. The display is connected via DVI to Mini Display Port adapter. When I connect the external display, my MBP switches to the AMD card. Here's where the problems begin. If I'm using Davinci Resolve, Capture One Pro or any other software (that I use regularly) that uses the GPU extensively, the cpu usage will rise, the computer will start to feel sluggish and my productivity almost becomes none because even the simplest tasks such as opening another tab in firefox or safari takes anywhere between 1-3 sec. When the computer starts doing that, I cannot play a simple HD video at native fps and the whole machine basically becomes too expensive paper weight. The strange thing is that even after I quit all programs, the system cpu usage continues to be high, around 50% with kernel_task being the star using all this cpu and it keeps using all of this cpu forever, at least until i shut it down or disconnect the external display and manage to make it switch to the internal Intel gpu.
The problem started after istalling the 10.9.3 update and it's still there with the 10.9.4 update. I even formatted the computer and reinstalled everything but the problem still persists.
I haven't experienced anything like this on 10.9.2 and the machine was actually quite fast before that. Now, I have too expensive paper weight on my desk.
Since the problem is very specific, I doubt many users will complain and I doubt Apple will ever do anything to fix it, at least until hopefully the new drivers in 10.10 fix the issue hopefully.
My question is:
1. Has anyone else experienced this and managed to solve the problem?
2. How can I downgrade to 10.9.2? I don't have time machine backup but i have bootable usb with 10.9.2. Will it help?
All best,
Goran

2011 MBP with SSD/Time Machine Issues

Early-2011 MBP (MacBookPro8,2)
8GB RAM
240 GB OWC Mercury Electra 6G SSD (newly installed)
750 GB HD (original boot drive, now with the user folder on a 500 GB partition and a 250 GB Windows boot camp partition)
I replaced my 750 GB boot drive with the OWC SSD recently and put a fresh install of Mavericks (10.9) on the new drive. I used the OWC bracket and moved my old 750 GB drive to the optical drive bay. Erased and reformatted the 500 GB partition (on the 750GB drive) as a Mac OS Extended (Journaled) drive. I moved my Home folder to the Mac partition. I've since reinstalled apps and replaced my Home folder contents from a clone I made.
When I try to run Time Machine (either via a directly connected HD or via Time Capsule) I end up with the machine freezing up. It doesn't always totally freeze up, but once I try to click around or open the Finder or an Application I end up with the beach ball and end up having to do a hard reboot (hold power button til it shuts down). If I don't wait awhile before restarting sometimes the machine won't find the startup disk. It does seem like Time Machines starts... as it does start writing the backup record. It never finishes though.
Based on some of the other threads I've read I ran the following command:
find ~ $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl $ 2> /dev/null | wc -l
And was given the number "235".
Any pointers?

There's no simple or easy way to do that, and it depends on your circumstances. See Transferring Home Folders not on a Startup volume for some suggestions.

Early 2011 MBP Slowing Down

Hello, I have an early 2011 MBP (15-inch), system report below:
MacBook Pro (15-inch, Early 2011)
Processor: 2 GHz Intel Core i7
Memory: 16 GB 1333 MHz DDR3
Startup Disk: Macintosh SSD
Graphics: HD Graphics 3000 512 MB
Lately, my MBP has been slowing down a lot.
I tested out a bunch of flash sites, but it does not seem to be the problem. Like I said, I have 16gb of RAM (combined with what I have located above, i7, etc), and have had numerous flash sites up, but no slowdown. The problem is recent, in that I've noticed it in the past 6 months. Nothing changed in that period at all to cause this problem.
I've run this setup for a couple years without issue (SSD where the DVD player used to be, and the HDD where the old HDD was located), without issue.
My MBP gets so hot that I have to move it frequently for scare of erythema eb igne (stupid technical term, but I might not be joking, and would rather not joke around about something like that.but seriously it get that hot where your only option is to shut off the MBP. I know that might sound extreme. But my MBP gets that hot. Especially if you are running a program like Premiere. I understand the power and RAM that it takes to run a program like that, but it was shocking. This is a program (Premiere) I ran without problems previously..
Checking activity monitor (and iStat), RAM does not seem to be the issue. CPU seems fine 88-90% usage,
Usually have 7-8GB of RAM available, and the CPU usage under 90%.
I have no idea, but I will be taking a can of compressed air to the MBP.
I was just wondering if anyone had any other ideas or had similar situations to help me out?
Thank You,
T

Early 2011 MBP 17 Random Shutdown and Battery Behavior

Hi all, new to the forums here.
I recently purchased a refurbished early 2011 MBP 17' 2.2 Ghz i7 with 8gb and 10.7.5. Out of the box, machine looked great, but I noticed that the power cable was different than the one I had for my early 2011 MBP 15' I have for work. This raised an immediate redflag (buying from a refurb site outside of apple is always a cause for concern IMO) so I abstained from using that charger until I knew a little more. I plugged in the machine and booted it up and everything worked great. The batter was close to 100%, so after charging for approximately 20 min, I unplugged it, and the laptop immediately died. I powered it back on, and the harddrive began to spin for a few seconds, then the same result, total loss of power. Started up again, and I was able to boot into OS X and play around for a bit for a period of time before again, shut down.
For the next few days, same story. I was able to at one point, drain the battery completely and do a full cycle charge. The first time I did this, no change in behavior. Again, a few days later, I was able to drain the battery and perform a full cycle charge, but this time, a major change in behvior. Since the second full cycle charge, I have had absolutely no power problems. I haven't really "pushed" my MBP to see if fully utilizing the CPU/RAM/GPU will produce the similar results I had early, but it appears that everything is working great.
Here a few interesting notes to my situation.
When I was first operating the system (when plugged in, there were no shutdowns, only while on the battery) I pulled up my system report, and noticed that my battery cycle was very low (~5). This seemed odd, because I had opted for a used battery instead of a new one.
Prior to reinstalling Mountain Lion, my volume up key would trigger a few strange events. The screen for briefly get quite bright, then all open applications + the doc and widgets would restart (similar to killing explorer.exe in the windows task manager).
Since performing the fresh install, I have had abslutely no issue with my MBP and I love it, its a beautiful machine. However, as I purchased refurb, I'm hesitant to proceed (I will exceed my return period in ~2 weeks) without knowing my machine is in prime working condition. I have read issues about early 2011 models having issues with batteries and GPUs, but my symptoms were dissimilar to those described by others with those particular issues.
Any thoughts?
I have a genius appointment tomorrow evening for a general diagnostics check, but if others have experienced these issues, I would appreciate some input.

Lately, I've been getting a blue screen in the midst of working and have to do a cold reboot to end it. Seems to happen when I'm closing windows or quitting applications. Not always, but sporadically. What causes this? I'm using 10.6.8 on early 2011 MBP.

You have 10.6 on that machine, I suggest you stick with it for performance, third party hardware and software reasons as long as possible.
Consider 10.8 (not 10.7) when it's released, because 10.7 and 10.8 will require a new investment in software and newer third party hardware as it requires newer drivers the old machines won't have. (forced upgrade because of software, really nice of them)

Early 2011 MBP - Won't install updates?

Today was the first time I've used my MBP since finishing school for the year and I decided to try and install whatever new updates were recently released. However, whenever I hit the option to restart my mac to install the updates it... it seems to just return me to the log in screen, and when I check my Software Updates they're all still there waiting to be installed.
Help?
It's an early 2011 MBP, running OSX Snow Leopard 10.6.8. 2.3 Ghz Intel Core i7 with 8GB RAM - if that helps at all.

Yeah, that probably would've helped, huh?
The latest iTunes, iDVD, iMovie, iPhoto + the latest firmware and security updates.

I'm selling my early 2011 MBP because I just bought a iMac. Could someone please tell me how to remove all my information from it but leave the OS working. Thanks so much.
