IMac :: Intel Core 2 Duo OS X 10.6.5 Completely Freezes And Crashes
Nov 24, 2010
I have a problem with my iMac 2 GHz Intel Core 2 Duo (2 GB 667 MHz DDR 2 SDRAM), running OSX 10.6.5. OSX crashes and freezes all the time. Nothing works anymore. Sometimes it just freezes, and I can only move my cursor, but nothing reacts anymore. Sometimes the screen blacks (or sometimes blanks) out or shows the weird moving colours as shown on the photo I just took below: After restart, it often happens again and again. Then the iMac is fine for a couple of days, before it freezes again. Can anyone diagnose the problem from the info above?
For those of you with a new i7 iMac, if your machine is completely idle, what does your CPU usage look like in Activity Monitor? I'm routinely seeing Finder consume 70-90% of my CPU. The single CPU bar meter view in the dock is basically pegged most of the time. The graph shows it as system usage. If I open the CPU History window, all 8 threads look like they're just about maxed out.
The last 2 days my iMac has completely frozen on me at random times. Frozen meaning, no mouse movement, no keyboard activity (caps lock not responding) and no OSX activity whatsoever. Temp at the time 41C, CPU Usage at 21% or smth, Fan speed at around 1200rpm. However, I don't get the infamous kernel panic error. I haven't changed anything hardware wise. I did have a couple of months ago the graphics glitch problem. Last software update was the iWork one. iMac is Aluminum 20' with C2D 2.4 and ATi 2600 Pro.
My iMac randomly freezes and crashes on me. Most of the freezes occur when scrolling with my trackpad on websites with Google Chrome. I get the pinwheel and have to use the power button to turn off and on the iMac. I haven't noticed any particular connection to Flash websites or video related sites. It just seems kind of random. I've also been careful to have absolutely nothing else running and it still does not prevent it.
Also, from time to time the iMac will crash and go to a solid color screen. Either Blue-Gray, White or Black. It seems to be random colors. When this happens, I have to use the power button to cycle it off and back on again.
Some info about my iMac: Model Identifier: iMac7,1 Processor Name: Intel Core 2 Duo Processor Speed: 2 GHz Mac OSX 10.6.8
What could be causing this or how can I diagnose the problem? I can give more info if needed.
Seems to be happen at any time. Will not respond to force quit and does it all the time if viewing youtube? Sometimes screen turns black but mostly just freezes.
I have a 2006 imac (1GB memory) with tiger that had been having some issues last year with crashing so I ended up and installing snow leopard and it worked great for about a year and now its acting up again. It freezes at least 2 times a day and I can't open the force quit window so I shut it off manually, but when I turn it back on it has these weird lines on it like a line of pixels got corrupted or something, but sometimes they go away. I save everything to an external drive so I don't think it has to do with it being overloaded. I did notice it mostly happens when I'm multitasking (more than one tab open, or word and firefox open at the same time) or watching a movie. Occasionally it will crash and the screen goes a peach color with white lines and I have to manually restart.
Every few weeks my iMac will suddenly freeze, the screen going black or white or pink etc. The only way I can get the computer back is to hold down the power button to force a shutdown. Then after a restart everything is OK for a few more weeks. Usually it occurs when I am on the internet. I click on something and suddenly the computer is frozen. I am on OS X 10.6.8 and usually use Safari. Ironically when I opened this forum 5 minutes ago there was a similar sounding problem at the top of the list!

Since the last itunes update (May be a co incidence) , my 27" Mac keeps crashing with a white screen and flickering It then wont restart most times, even when using boot up options such as option, Cmd P+R. even removing power!waiting and restarting etc on most restarts wont work its a white screen.
Info: iMac (27-inch Mid 2011), OS X Mavericks (10.9.4)
first, I didn�t know if this thread should be here or in Buying Tips, but anyway. My doubt is about the brand new 27� iMac�s processor, If I should buy a more GHz one, but with only two cores, or should I buy little bit less GHz one, but with four cores.
It really worth pay $200 more? It really worth the four cores? My main needs are run CS4, some Final Cut, maybe Logic Studio, and switch between different OS's (OS X, Windows, and Linux). I think even a 21.5� model would be more than enough, but I just wonder If Quad Core gonna give me more power (I hope so).
My one week old iMac 2.7GHz Quad-Core Intel Core i5. first started problems by not goping to sleep even when I forced it.
I shut it down using the shut off button and unplugging it from power for more than 5 munites.
I turned it back on, it does the usual startup chime and then gray screen. I have restarted twice from the shot off button and still getting the same result.
This is an issue I've come across with Macs the last few years & it's only taken me until now to raise any question as to why. It's not specific to Snow Leopard.
Sometime after using my Mac for a while it will just completely freeze up without any explanation why. The CPU is below 50% and still has around 100mb free memory. Eventually if I leave my machine long enough it will get to the state where I can quit a few apps, but it still be awfully slow until I restart the computer.
I admit that I very rarely shut my computer down, most of the time just sleep repeatedly for as long as 2/3 weeks... This isn't a specific issue to the machine, I've experienced this on my old iBook, iMac & now MacBook Pro.
I just deleted yahoo messenger from my computer by going to finder then applications and throwing it in the trash. But when i reinstalled it by downloading from the website it remembered some info from before? How can I totally delete yahoo messenger?
I just got a MacBook last week, and am running 10.9.3. Twice so far, I've been using the computer and the UI ceases to respond: no response to keypresses, no response to the trackpad. The only way out seems to be a hard reset of the computer. This is a brand-spanking new Mac, although I have installed QuickSilver and Firefox. Have there been any issues with freezing on 10.9?
Bought and downloaded iWork '09 March 8 from authorised Apple reseller in Hong Kong, used it for a week. loaded software onto white MacBook 13'' 2.16Gz. machine is now 7 months out of the standard 1-year warranty (meaning I've owned the machine for 1 year and 7 months). Apple Auto Update cued update for iWork '09 (Pages, Numbers) on March 13, which I authorised for it to download. Left and came back to computer, which does not turn on. Tried resetting PRAM, SRAM, doesn't work - completely crashed, light next to IR port does not turn on, battery does not charge, but power adapter lights up green when connected. Went to CASE, in Mongkok (Hong Kong), over the weekend.
3rd party service contractor of AppleCare HK, which takes care of hardware problems. The counter rep said it will cost me HK$600 (US$100) just to examine the problem because the machine is out of warranty. I kicked up a fuss. he finally gave it a cursory look, say something is wrong with logic board and says they will have to charge me HK$10,000 (US$1,200 = which equals new aluminum MacBook) to fix it. But they said i should wait to speak to a Customer Service rep on Monday to see what more could be done. So I went home, took out the hard drive and put it into an external hard drive (SATA) case. Over USB, backed up my critical user files onto another macbook. There were "stop signs" overlaid my file folder icons, I clicked on them, opened them up, transferred these files onto another external drive.
I returned original hard drive into unbootable macbook (apparently this should have fixed it), did not try to power up one last time (see below). Called up AppleCare Customer Service on Monday (see below); they were helpful. At CASE (AppleCare's 3rd party contractor), technician pushed power button and to my utter amazement, the computer turns on. screen shows the machine was just about to restart - it was stuck on Apple Update, which has just finished downloading for iWork 09. The technician says actually I am the second person to have this problem - the other person was installing updates for iLife '09. Technician also says this has never happened before iLife or iWork 09.
So my Macbook pro started to stall for 10 seconds or so every few minutes beginning yesterday. Like I am just surfing the net, and it freezes completely for 10 seconds, than everything is back to normal. I don't know what to do to remedy the problem. I have Applecare so I could send it in, but wondering first if anyone has had this problem and knows a quick fix before I send it in.
Since a couple of weeks I am facing weird crashes on my 8core Mac Pro (May 2007). They happen from time to time. Sometimes directly after starting up, sometimes there are no crashes for a couple of days.
It seems whenever I launch a youtube video, there is a tremendous lag that occurs for a good 30 seconds before my video is able to be seen. It completely locks up my browser and freezes. Thought it was my iMac at first, buy Firefox works fine. I reset everything on Safari and still nothing.
using my early 2006 iMac with an Intel Core Duo processor. I have read several guides online on how to access the processor (taking apart the case, etc), and I am confident I am capable of undertaking the task. After reading this guide I feel like I will be able to do it myself (with the help of my electrical/mechanical engineering friend (still hasn't decided his major yet! I'm a physics student, so I should be capable as well, ha! Anyways as you can see, that guide gives very little information as to what CPUs can be used. I looked up the processor that they used in the guide (the T5600) and all of the results came up for a mobile processor. I have heard in the past that most of Apple's desktops contained "laptop grade" hardware, so it would make sense if it contained mobile components.
So the older Mac Pro's from 2008 have 2 2.8ghz Quad Core Intel Xeon processors, without hyperthreading, for a total of 8 cores, and the top of the line iMac has a Quar Core i7 2,8ghz with hyperthreading for a total of 8 (virtual) cores.
With the ghz being the same but less "real" cores, but probably newer CPU architecture, which CPU will actually be faster?
I usually have a few simple apps running at the same time...
Currently a UML App, Adium, Firefox, Skype, Mail & iTunes, and obviously... WoW.
For some reason, every now and again, it freezes, then returns to it's normal (high) FPS... anything I can do to speed it up? I'm thinking whether it's really worth buying it 8800 GT?
hey my friend is having a problem with his imac when he turns it on he gets a grey screen and stops there. there is also a grinding noise near the back maybe the hd or disc drive? it grinds 10 times then stops then continues for a couple minutes and then he gets a question mark on the screen.
i just purchased an iMac 2.66GHz Intel Core 2Duo (Snow Leopard 10.6.2) and I installed Canon Digital-Photo-Professional 3.7.3 (upgraded from Canon's website).I soon had big problems with the Canon Raw sw: after the start up of the application, every command I try to operate (even a simple click in the menu bar) makes the infamous coloured wheel to appear and I have to wait 10-15 seconds, and sometime more, for the command to be operated.I found on the Canon site this "cryptic" statement about the installation of DPP 3.7.3 on Snow Leopard: "Improvements to Mac OS 10.6 Compatibility Issues have been made, to fixes the following problems that occurred with Mac OS 10.6.
***This does not guarantee the software will work correctly in all Mac OS 10.6 environments.***"So what should this mean? Does it work or not?I also tried to go back installing DPP 3.4.1 but it's the same horrible story.I'd like to hear from people who is experiencing similar problems with the same configuration I have (Snow Leo and DPP).
I know other threads exist, but they don't have responses specific to me so what's the harm in one more?
So, I am going to be selling my late 2008 15" MacBook Pro this week to get a new 27" iMac and I just need some legitimate advice from those "in the know" on processors.
I plan on having this iMac for about 3 years to do the following tasks:
1.) Record and edit HD cable (1080i) from an Elgato EyeTV HD - will include some encoding of 2+ hour sports game recordings
2.) Some light editing of 720p iPhone 4 clips in iMovie
3.) Surf the web, iTunes, iPhoto, Mail, and all the other standard stuff
Assuming budget is an issue, would you recommend me spending the extra money for a Quad Core i5 iMac or would I be ok based on the info above just going with the base Dual Core i3 model?
Like, will there be a considerable difference in the two machines (factoring in processor and graphics card) that will really be worth the extra $300 - $400 for 3 years of use?
The ivy bridge processors are coming out soon (or may already be out). I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?
Info: MacBook Pro (13-inch Early 2011), Mac OS X (10.7.4)
I've upgraded my iMac 4,1 to a core 2 duo processor in order to install Lion although I still get a message from App Store saying that Lion cant be installed on my computer - I have all the basic system requirments - RAM - free space - latest version of Snow Leopard and processor ...
