MacBook Pro :: Clean Installs Or Just Migrate Data To Avoid Kernel Panics
Jan 9, 2011
I have a 15 inch 2010 MBP. When I got it, I migrated all my info from my previous MB. About 4-5 months into using it I started having issues w/ Kernel Panics. I did upgrade the HDD and RAM but the Kernel Panics happened before all of that. I took it to the Apple store and they ran some test on the hardware and software and said they couldn't find anything. Their advice was to just do a clean install. I wanted to avoid doing a clean install on all costs. Anyhow, I said what the who last night and backed up important files and did the clean install,
I have to say that the computer feels much more stable now. I was having a lot of little issues w/ Snow Leopard prior to the clean install. Most of that probably comes w/ me playing around w/ settings a bit too much. Also, I'll admit, I do torrent some software. In my opinion, thats what caused the kernel panics. Only time will tell if I continue to get kernel panics even after a clean install, but I think I'm good to go. So, do you guys prefer doing clean installs or just migrating your data? When Lion comes out, will you clean install or migrate to it?

I began having freezes unrelated to any new software or behaviors. The hardware check showed no problems with the hardware or memory, so I cleaned out the inside of the computer, used Disk utility, AppleJack, Mac Janitor and reset p ram (all said it was OK, then the freeze came back), and finally zeroed the hard drive and reinstalled OSX.
It was stable for a few weeks then the freeze happened again followed by repeated kernel panics. I went thru all the steps above again but finished with an archive and install and created a new user admin account. Until this point the freezes and KP were on all three user profiles. But now this new user admin is fully functional while the others are still messed up.

I know there are numerous posts already about whether to 'clean install' or upgrade to Snow Leopard, but I can't seem to find an answer to my question anywhere.
I have two computers that I've already upgraded to Snow Leopard - an iMac that's about a year old (with data on it that has been migrated between macs since Tiger) and a brand new MBP which is unblighted by any migrated data. The MBP seems much faster for the upgrade, but the iMac seems a little slower.
My instinct here is to erase my iMac hard drive and install Snow Leopard from scratch, which would presumably solve the sluggish performance issues.
My question is this: I have all my iMac data backed up on Time Machine. Is performing a clean install and then restoring my mac from Time Machine going to give me exactly the same problems as upgrading did? Or would it be better to selectively move data back to my iMac after a clean install?
If I need to do this the hard way (as I suspect) and selectively bring back my data to leave the junk behind, is there anything I can do before running a clean install to make this more painless?

If I were to do a clean install of snow leopard, would I later be able to bring my applications over via time machine. That being said, I currently have Adobe CS4 Design Premium and Microsoft office 2008 and itunes. Would I have to unlicense the programs and deauthorize my account before the clean install to make sure that i wouldn't lose the licenses and the authorizations.

I read on another forum that some people seem to do a clean install of Mac OS on their machines every year or so, whether they need it or not. I'd never heard of this before and thought that I'd ask here to see if this is common practice?

I have had the Macbook air 11.6 for five weeks now and it has been rock solid except for a couple of kernel panics. Once when I first got it I got a kernel panic in Safari. I only use google browser now. I got a kernel panic two days ago. I went to open the lid and it did not come on. I found out there was a kernel panic. I am afraid if I take it to the genius bar they will have me reinstall the OS and add one app back at a time to see what is causing it but since they are so infrequent this is obviously not convenient. Also I have had my IMac 24 for three years and have tons more junk on it and have never got one panic.

What does it mean when a kernel panics? People talk about it all the time, what does it mean?

I am currently planning to upgrade my 2gb RAM and I heard that my model supports up to 6GB of RAM, hence I am planning to upgrade to that size cause Aperture uses lots of memory and I use Aperture a lot. I am planning to get it from here: OWC 6GB PC5300 DDR2 667MHz DIMM Upgrade Kit. Everything is cool and all until I find out that some users are having kernel panics on OSX 10.6 with 6GB RAM (which is what I am using). It is now 10.6.3, so anyone care to report if it is safe to use 6GB or the problem still exist?

Can anyone tell me what's going on? My MacBook gets a kernel panic every time I boot it up. Should I reinstall the OS?
I just repaired disk permissions and that did nothing.

I got a new 15" i7 MBP w/7200 RPM and hi-res anti-glare last Thursday and since then I've had a number of kernel panics, three today
Any suggestions on what it could be or what I should do?
From the looks of it it has something to do with the graphics card, maybe the auto switching feature.

i have a 2.2GHZ intel core duo 2007 MBP, which once ran Tiger and is now running 10.6.3I had the graphic card break down associated with such models, and it was replaced thanks to the extended care plan-I originally had 1Gig of ram, but 1st got an extra 2Gb of danelec ram, and finally another 2GB- it ran fine for a year or so-then I started getting these kernel panics, which seem to be ram related-on tiger- I changed the HDD, switched to snow leopard, and they continue, they're apparently RAM related, yet what is odd is that they can be reproduced with any RAM combination involving 2 sticks- the original apple 1Gb + any of the two GB ram sticks, the 2GB ram sticks together-- it's all the same, the screen goes grey and i'm told to shut down the computer
with one ram stick it works, apprently avoiding the issue-i've moved the ram around, checked the slots, reset the PRAM,yet the issue is still there.now i know that I should be using paired ram, and will do so in the next coming months when I can afford it- yet what has happened to make the make the MBP seemingly refuse two sticks of RAM when it didn't before ?I'd also need to know that this is not a logicboard issue if it's possible- the logic board was changed due to the NVDIA bug, so it's a year old or so-I'm running it on the 2GB danelec as I type, no issue, the samsung ram works as well, and so does the 1GB apple ram, in any slot, yet two slots of ram causes the kernel panic crash- the area near the ram slot also seems to get very hot

Recently got my Retina MBP and love it, but have been getting quite a few kernal panics. Not sure why. I am suspecting Chrome Canary as the culprit but I never had any issues with it on my previous Macs. Here are two of the kernal panic logs:Â

I got a new macbook pro a week ago. The first time I shut the machine down it experienced a kernel panic right after I selected to shut down the computer. Programs randomly crash while I am using the computer. The apple store said that crashes are most likely due to CS3 because it was not properly updated for the system, so they installed the CS3 updates. The next time I used the machine after installing CS3 updates, it experienced another kernel panic upon shut down. I would like to hear about known issues with the Summer 09 macbooks. I am trying to determine if this is a hardware, software, or an OS issue.

I have a 2.2Ghz Macbook Pro 15" (2007) that suddenly can't get past the startup screen and ends up with a kernel panic and the You need to restart message. Happens 100% of the time now. I had Leopard on it when it started kernel panicking. I managed to boot from an external drive and installed Snow Leopard, but it started okay once or twice, then started having the kernel panics at startup again. Tried SMC reset, but no go.
I then tried going back to Tiger, thinking it might be a problem with the RAM. Tiger actually installed okay, and after it worked okay for a bit (2-3 times, maybe half an hour), I tried to install Leopard again. And got only kernel panics. And I can't install Tiger now either.
It occasionally starts up from an external disk that I use for installs (has Leopard and Snow Leopard on it), but that's not 100%. And I can't even get thru an install now. I started up with it in Firewire Disk mode, wiped the drive and cloned a system from my iMac, but even though it seemed to go okay, when I shut it all down and tried to restart the Macbook Pro, I got another kernel panic. Any ideas? I've switched 3-4 different RAM modules, and I don't think they're ALL bad. But no go. I've changed hard drives too.
Seems weird. I mean, it doesn't seem broken, as it starts up, goes thru the startup screen, seems to pause a bit and, instead of going to login, stops with a kernel panic. I assume it's HARDWARE, not software. But hardware problems are usually the RAM, sometimes the hard disk; and if the MBPro doesn't start up at all, then the logic board is probably fried. So what else can cause these kernel panics? A bad keyboard/trackpad (top case)? Bad PRAM battery?

Regarding the black screen issues, kernel panics and occasional freezings upon wake, I'm curious. After the EFI update I still had these problems (on an already replaced 11" from the apple store). But as soon as I uninstalled flash, they disappeared.. Anyone else with this apparently "rare" issue notice this?

I am running a Rev A Macbook Air. I performed a software update today on all of my Macs and only the Air is having problems. Nothing but Kernel panics telling me to restart. I tried booting into safe mode, single user mode, reset the PRAM, tried to reinstall via remote disk. I get nothing but Kernel panics.

recently I've been getting a lot of kernel panics. They usually happen at random times when I'm browsing Safari. Most of the time I can reboot normally but once I got 3 repeating beeps when trying to start-up.
This is from the problem report:

I have just now received my purchased 13.3 inch Macbook Pro model, with BTO 4Gigs RAM, and 250 HDD.
I opened the Macbook pro, and it worked just fine. First thing I did was to enable the WiFi, perform a software update, and update the system using Software Update with the combo update to Snow Leopard 10.6.2 (it was 10.6).
Immediately after performing the update and restarting, the computer crashed on startup 3-4 times, and still refuses to boot. It appears this is a kernel panic, with the first line saying "Panic Version mismatch between Kernel and CPU " and some other things like the version of the system and darwin, and the CPU model.
I booted from the DVD without problems, and performed a Disk Repair (which found no problems) and a repair permissions (which also found no errors).
Strange thing: When I selected the "startup disk" application I selected my internal HDD but it displayed 10.6 instead of the recently applied 10.6.2!!
Rebooting still crashes the computer, with the same kernel panic.

I've had my MacBook for almost 5 years, first Mac I ever purchased, and have told everybody since then how I've never had one single problem with it, virus, or anything. My desktop PC would crash about every 6 months prior to getting my MacBook & the employee at Best Buy talked me into getting a Mac. I've been extremely satisfied in every way with it until now.
I finally bought a mini-dvi to hdmi cord to hook up my 70' Sony Bravia as a secondary display, but ever since hooking it up I'm getting constant kernel panics where I'm forced to restart my computer. This happens atleast 10 times a day and sometimes as much as every 10 minutes. It's not the TV as I have the same problem connecting to my 44' Philips TV. Am I just constrained to only using the Macbook screen connected to my laptop?

I Have a MacBook Pro mid 2009 13 inch and since yesterday the computer will not start, it simply shows a white screen, then the apple sign and then after several seconds this comes up and then it repeats again and again forever with a message that says " your computer restarted because of a problem wait or press any key to continue" but then after about five or six times it comes up wit. A screen that looks like the startup screen but in the middle of the grey/white page there is a circle with a cross through it where the apple sign should be.Â

I'm running OS X version 10.4.11 (Tiger). It's a 13" Macbook, two years old, from August 2007. I've recently been having a bunch of problems with it.
First, it drops its wireless connection a lot. Most of the time this happens while I'm playing World of Warcraft, but I've seen it happen even when I'm not. Everyone else connected to the wireless will have absolutely no problem with it, but my Airport icon in the upper righthand corner of my screen will go grey and then connect again, then go grey, connect, etc. I also experience a lot of latency in my connection when others don't (example with WoW... someone else will have 98ms latency, and mine will shoot up to 2500ms or so). Most of the time when this happens my entire computer seizes up. My game skips, my iTunes skips, my mouse skips or won't even move, I can't type or click, etc. Additionally, I've had it happen even when I'm connected to the internet with an ethernet cable with Airport turned off, and my internet connection will die completely until I restart my computer.
I've had problems with this computer in the past as well. About two months after I bought it, it wouldn't boot up and I had to reinstall the operating system. Then a year after I bought it, my motherboard crashed, and they couldn't really tell me why it might've happened.
Second, I've had two kernel panics in the past two months. The first one was July 18th, 2009, and the second one happened just about half an hour ago today (Sept 4th). The panic.log is as follows (both dates are included):

I have a 2-yr old MBP 3,1 (the first Santa Rosa line) which has recently hit a slew of problems (bad fan, new display, new hdd, new logic board) over the last 3 months. I thought all was fixed then yesterday it suddenly dies, starts kernel panicking on boot, and I can't even boot from an installer disk. I took it in to the Genius Bar today and the guy puts a stick of their RAM in and it seems to work +/- ok. He won't do any more until I put the original RAM back in (upgraded to 4 gigs a year ago). I take the laptop home, and it magically starts working. I grab a couple backups and it starts kernel panicking again so I grab my original RAM and put it in. Now it's still kernel panicking and I'm effectively completely locked out of my MacBook Pro (the RAM worked fine in my wife's 3-year-old MacBook which takes memory of the same specs).

I have a 2010 MacBook Pro running the latest iteration of Lion. Recently, the computer has experienced frequent kernel panics (three today alone) requiring the laptop to be restarted. I have noticed that these tend to occur more frequently when I wake the computer after letting the battery drain down to near or below ten percent of its capacity and subsequently plugging it in after it goes to sleep.Â
The only other clue I have is that every time the computer experiences a kernel panic and restarts, Spotlight re-indexes my hard drive (i.e., the magnifying glass icon in the upper-right-hand corner of my screen has the little blinking red dot inside of it).Â
I have read a couple of things on the internet about how this may be due to Symantec Anti-Virus, which I have installed on my computer. However, that is pure speculation on my part based on a random post on a non-Apple-sponsored discussion board somewhere.Â

The first couple kernel panics I had appeared to have been caused by Trend Safe Web Surfing for MAC i have since uninstalled that and it keeps panicing.. programs i always have open
- safari
- firefox
- skype (text chat only .. never video)
- Outlook for Mac
- Adobe CS5 Dreamweaver  Â
there is never anything consistent about when it happens

I convinced/helped a friend upgrade her 1.83Ghz CD MacBook to Snow Leopard. It has not been a smooth ride. Right off the bat there have been persistent and recurring DNS problems. She has also found that it won't shut down without her going through and quitting or force quitting open apps--skype being of particular issue. Tonight she had a kernel panic, it seems. It appears skype is the problem app, but this didn't occur before the SL upgrade. Is it coincidental or correlated?

My friend has been having trouble with his 15 inch, early 2011 macbook pro. He is running OS X 10.9.4Â
It seems to work great until he streams media or connects to his school email. Â
I've taken a picture of what the screen looks like when it last froze while he checked his email:Â
Shortly after this, he had trouble booting the macbook back up. He would see either a blue screen with light and dark blue vertical lines. He would also boot up the computer and it would be stuck on the white loading screen without the apple logo.Â
I also have the console logs for the past few bootups:Â
9/1/14 6:09:13.000 PM bootlog[0]: BOOT_TIME 1409609353 0 9/1/14 6:09:35.000 PM kernel[0]: vm_page_bootstrap: 808086 free pages and 232298 wired pages

my late 2006 macbook running 10.4.11 has been acting very strange since yesterday. first, it freezes while i'm recording something off of isight and i have to restart. works fine for 30 minutes until it randomly restarts (probably due to heat) and takes me two reboots and some time to fix it (i have to put an ice pack to keep it cool). then later in the night, it randomly restarts again and takes two reboots to get it back. then in the past hour, the screen has frozen, it went into a kernel panic and it randomly restarted again while i was trying to post this the first time. and also, it's been running very hot despite having no applications running.

Late 2007 MBP 15" kernel panics upon boot up and requires two /sbin/fsck -fy filesystem checks in single user mode/safe mode in order to get it to boot. Once you are at the login screen, it hangs after a bit/login and the screen starts flickering fast and visibly. There is also a faint visible "blotch/ink blot" like transparent area on the screen when it flickers (just to let you know, the screen looks FINE, no black blots (common for broken LCDs) and there does not appear to be any physical damage.
Anybody know what the heck might be going on? So far, I can already tell you that I DON'T KNOW if the machine was dropped or what the user did do to it (I'm only fixing it).
Also, during the fsck, I commonly get this: "Incorrect block count for pcscd.pub" it should be 16 (or 17) which gets me scratching my noggin (googled it, not much that I was able to do to fix the machine though). Fsck fixes that, but upon the next reboot after the kernel panic, I get it again in fsck.
We called the machine but of course when it was not bought the AppleCare was not registered (even though we bought it for the user) so right now we're waiting for Apple to register it (had to fax the receipts/POs) which usually in my experience only took few minutes to complete before we can even take it to the store.
My questions are:
1.) What is going on.
2.) Hardware problem? Bad Logic Board/GPU? Hard drive going bad?
3.) Software issue? Reinstall OS X?

I tried to locate /Library/Logs/PanicReporter according to this link to no avail. I'm not happy with logging using verbose mode and having to retype it all up. I also don't have it in a network of macs to allow for this technique and I feel as if there's a pretty obvious way of capturing these reports that I'm missing.
