I have a macbook pro and i just update it with OSX Mountain Lion. At last few days an annoying sound start to play and after that the macbook stack. Now, it restarted automatically and show up on the apple logo screen about kernel version and something like panic(cpu 0 caller etc.) Also Debugger called:<panic> etc. Does anyone know about this situation what i can do? Thanks a lot.
MacBook Pro, OS X Mountain Lion
Work through this knowledge base article, especially the safe boot mode, and see if that doesn't clear things up for you.
Thanks a lot. I will follow the steps and i will tell you whats going on.
Hope that helps, kernel panics often resolve with just a safe mode boot and then restart again...unless there is a physical problem such as bad memory but that usually shows up just after installing the memory, not some time later.
Also the annoying sound is starting when i press the start button to open my MP but without opening the MP just a black screen.
When you say an annoying sound, can you describe it more? When my MBP starts there is a kind of whine and the sounds of the hard drive unlocking and starting to spin up, a clicking sound when that happens. All of that is normal. So just how loud is the sound and can you describe it a little more?
Sure. Somethimes the MBP starts normal with the normal sounds. But sometimes a more louded sound is heard. Also as MBP working this sound starts and then the MBP stacks and shuts down automatically. It plays three times and stops for one second and then again three times...
Ahhh, do mean three beeps, then three beeps again? That means there is fault memory. How old is this MBP, and did you install new memory or someone else recently?
If you installed memory modules yourself, reopen the back, take the modules out and then reinsert to make sure they are seated properly.
If this is Apple installed memory then it would be good to visit an Apple store genius bar and have the techs check it out.
Unless I am miunderstanding what your are describing.
Panagiotis, off to get croissants and coffe for breakfast...Saturday tradition for us so be back in a little while.
It is old. If i remember well is a model of 2008 or 2009 summer term. Yes three beeps and the three again. I do not install any memory recently or before. So because i am at Cyprus now and I will be back to UK at October we have an Apple retail store in Nicosia to bring it to them. So the problem is with memory?
Three beeps at startup means there is a problem with the memory,the modules may be faulty or not seated properly.
4 beeps-No good images in Boot Rom
5 beeps-Processor is not useable
If you are comfortable working inside your MBP, take the back off and remove then reinsert the memory modules. See it that helps. If not, a visit to the Apple store in Nicosia would be a good idea and have the techs check it and if it is only bad memory, you can see what they will charge you to replace the memory modules.
OK. I will remove the memory modules and put them back again if not i will go to Nicosia. Thanks a lot Ralph. Have a nice day.
I wonder if changing RAM Memory solve the problem. What do you think about Corsair ram memory?
Check the exact memory at http://www.everymac.com by looking under MacBook Pro, then the year/model that matches yours, and then find the information on the memory your MBP uses. There are some very good sources of memory: Corsair as you asked about, Crucial and OWC. I have dealt with both Crucial and OWC and found them to be very good companies. Recent postings about Corsair have all been very positive...users have had good results with that memory and been very pleased with it. So anyone of those three would be great to deal with.
If the whole problem is the memory modules then replacing would be a good idea. And if you can get to Nicosia easily, having the techs at the Apple store test and tell you it definitely is the memory modules would be a good idea.
Best of luck and hope this works out for you...and be sure and post the end result, I would be interested in hearing how this works. We are all fellow users on here and not Apple employees so the feedback helps all of us.
sorry for the big late but i am not being at home since tha last day we communicate. So i remove the ram memory and installed it again and the problem is resolved. Thanks a lot,
You're welome, glad it got resolved...sounds like just ram not seated all the way...easy fix to an annoying problem.
Macbook Pro problem - Importan!
