MacBook :: Freezes And Crashes During Startup

Jul 1, 2014

I have an old macbook, its about 5 years old, one of the first aluminum models.

It has always served me well but now it has broken.

When I try and start it up it shows the grey loading screen, I see the little stripes rotating, to show that something is loading and then... it turns off.

MacBook Pro :: Crashes And Freezes - RAM Upgrade From 4GB To 8GB Safe

Feb 16, 2012

I have a 2010 15" Macbook pro and I was wondering what information do I need to know to be able to upgrade from 4GB - 8GB. My macbook pro sometimes freezes, I did a clean install of OS X Lion two days ago, and now I am still having some crashes and freezes, I was just wondering if I need to add an extra ram. Also, I would like to know what's the maximum of Ram MBP could handle or be installed in.

Intel Mac :: Freezes And Crashes Randomly

Feb 3, 2012

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.

Intel Mac :: It Freezes/crashes Constantly?

Jun 13, 2012

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.

MacBook Pro :: Snow Leopard Startup Freezes At Grey Screen?

Mar 15, 2012

My Snow leopard machine hangs during startup at the screen with the Grey Apple logo.  It appears there is a SW issue with my OS X boot partition.  Here are facts I have learned:The computer boots fine if I hold option at startup and select my boot camp partitionThe compute boots fine if I attach an external HD with OS X 10.6Running a disk repair from the external HD, I see the following two issues that are repaired.  Also, note the last line about boot partitionsAfter this disk repair, the disk will still not boot, it hangs at the Grey Apple logo.Booting in safe mode does not resolve the issue, the machine will still not boot to a desktopBooting in Verbose mode, drivers initialize with the last succesful line being the ethernet drives (I believe) and then the hangup occurs.  It is unclear what state the boot process is at on the hangup. 

This situation has happen twice in the past few weeks.  The first time I did a reinstall of OS X to resolve the issue.  Then, the issue appeared again approximately two weeks later.  I'm hoping to avoid a second reinstall (And really, avoid this issue in the future).  It seems perhaps something in the boot partition table or the OS partition, although disk utility says the partition is fine.  I have downloaded Test Disk 6.13 to look at the partition table, but I don't know how to interpret the outputs of that program.

MacBook Pro :: Lion Loop-freezes At Session Startup Login On 15”

Apr 10, 2012

Notebooks affected by this troubleshoot:Macbook Pro 15" 6,2 Mid 2010 (OS 10.7.3) with all Apple updates installed - 2,66Ghz Core i7 - Apple SSD 128GBMacbook Pro 15" Late 2011 (OS 10.7.2) - 2,4Ghz Core i7 - standard specs Troubleshoot : At startup, Lion freezes before the user is able to type his login/password. We see the login prompt interface of Lion, but can't even move mouse cursor.Keyboard's inactive too because system is frozen.So you must force a shutdown.And it's a loop-freezes. You'll try several times to boot your laptop before it will succeed to open. (it's a 5-times boot to succeed - average) I've tried several times: P-Ram reset, repair the permissions of Macintosh HD with latest Lion recovery & from an external boot too.None of this has solved this issue. I'm sure I'm not the only one who saw that issue. Have to boot 5 or 10 times his Macbook Pro to succeed a boot is not a normal use

Laptops :: MacBook Freezes On Startup / Can't Find Test For Hard Drive

Apr 11, 2010

My August 2007 MacBook runs OSX 10.4.10. It has performed flawlessly since my daughter bought it in 2007, and perfectly after I purchased it from her last september. The other night I was surfing the web while flying on a commercial airliner. (GoGoNet or something similar) Performance was kind of slow but I attributed that to the in-air wifi, which I had never used before. Then the browser started to hang with the spinning pinwheel. Option apple escape WOULD NOT force quit safari. After a few shutdowns using only the power button, the mac hung up on startup. I hear the chime, see the apple icon, the gear turns but it never goes past that point. It may be significant that the plane was flying through scary turbulence when my problems began.

When I boot up using the mac install disk 1, I can get it to start cleanly using the C key, the D key and NO keys. But when I run the hardware diagnostic, both short and long test, the mac comes up 100% clean. But i cannot see any test for the hard drive. When I try to run disk utility, the colored pinwheel arrives and it never goes away. When I go down the road of re-installing the system software, I cannot see the target drive.

When I put my ear on the deck, just to the right of the track-pad, I can hear the hard drive quietly spinning away with regular - not random - clicks.

I see that Apple is quietly replacing these hard-drives, but the affected computers seem to have a folder/question mark on the desktop on startup, not the apple/spinning gear.

I really would like to be able to recover my photos and some files if the hard drive is going to be swapped. But I am resigned to the situation that these un-backed-up files will be forever lost.

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?

OS X :: Snow Leopard Freezes - Crashes - System Hangs

Dec 7, 2009

A few months ago I had a problem with my Macbook Pro, (late 2009 model, 15" 2.53 ghz) that many users with Snow Leopard have, the random 30 second freezes. I simply reset the PRAM and SMC and I never encountered it again. Now, out of the blue, on Sunday (yesterday), I started experiencing these hangs again, but worse. The night before I had been browsing the web and my battery went to reserve and shut down, so I plugged it in and when I awoke and turned it on I started experiencing problems. I figured I would try the same fix, and it almost seemed to make the problem worse. Now if I shut down the computer via "apple -> shut down", then turn it back on and log in etc., from the first few seconds the machine hangs. If I open a folder I get the immediate beach-ball and the machine is un-responsive for anywhere from 1 minute - 5+ minutes.

I have read a lot of fixes for this problem, but most of the people's problems resulted from using Safari or Spotlight. I strictly use Firefox and very rarely even open Safari, and I think I've used Spotlight maybe 3 times total, none in the past few months. So far the things I've tried are:

- Reset PRAM
- Reset SMC
- Run Disc Utility and verify, repair etc. (from SL install disc)

So I'm wondering right now what can I do? Its finals week right now and im in college so wiping my HD is not an option. I feel like there is just something hanging the computer but I can't find the culprit.

Final Cut Pro :: Install Snow Leopard Without Worrying About Freezes And Crashes?

Jun 23, 2010

Because of the many problems I heard about using FCS3 with Snow Leopard when they both first came out, I've held off upgrading my OS from 10.5.8. Now that some time has passed, is it safe to install Snow Leopard without worrying about freezes and crashes with using Final Cut Studio 3? Also, have most of the 3d party software developers updated their apps for 10.6? I'd like to install Snow Leopard for my other apps but not at the expense of FCS.

OS X :: ITunes Crashes On Startup?

Mar 30, 2010

I closed down iTunes and opened it back up to discover that it wouldn't open anymore. I tried removing the library file, thinking it might have become corrupted somehow, and iTunes would sort of half-open, but not for long. And then when I'd try to open it up again, it would crash.

At this stage, I could get it to briefly open every time by removing all the library files every time, but then it would recreate them, and when it close/crash (and it would do this every time fairly quickly), it would once again not open at all unless I removed the library files.

Mac Pro :: Crashes On Startup After Installing SSD

Sep 10, 2014

Recently had repeated kernel panics and replaced an SSD with the original SATA HD and did a fresh install. Upgraded to 10.9.4 and machine ran fine for a month. Meanwhile I returned the SSD and a replacement was sent. Carbon Copy cloned a back up of the SYS HD onto the new SSD and replaced the SATA with the new SSD. Twice have had crashes on boot, shuts down, reboots and then successfully loads. I have an ATI Radeon R380 pci card in the extra PCI slot running to an external RAID. Reading the report it appears as if there might be a conflict with the ATI software. I re-installed the software and successfully booted, machine ran fine for a day. Next day on start-up, crash and reboot, successfully loads. This is the report it generates.

OS X :: Network App Crashes On Startup Everytime?

Dec 17, 2009

I've searched everywhere for a solution and I've had it before on another Mac, but can't remember how I solved it. Hope someone recalls the solution for this issue. Please don't suggest updating to 10.5, I'm not investing in a copy just for this old PPC G4 1.2Ghz iBook with a dead Firewire port (another famous iBook flaw).

Problem - Every time I launch Network from the Go menu, it momentarily shows (just a flash) the window and immediately crashes and disappears. Repeated efforts to launch does nothing.

I've deleted the appropriate prefs from the Library and still failure.

Intel Mac :: It Crashes Constantly At Startup?

Apr 13, 2012

I've had Mac's since my IIsi in '91 and currently the proud owner of MacBook Pro, iPhone and iMac which is just 18 months old.2 days ago I switched the machine off (iMac) and it hasn't been fully back on since. Each time I start it it automatically goes into soft boot mode. As the small bar moves across the screen it stops after about 1 centimetre (.4 of an inch) and simply whines and shuts down. I've tried the old tricks of holding down 'c' and 'd'. On one of the attempts I did reach the desktop and managed to run disk utility which said there were no problems. However, once I rebooted it simply carried on doing the same. I also managed to run Techtool deluxe which comes with the Apple Extended Warranty. Unfortunately it's not fully compatiable with OSX Lion so didn't run properly. 

I've not known a Mac to be so knackered before. I have tried the command-R scenario but I don't think reloading Lion OSX is the cure for what appears to be a serious problem. When I shut down the iMac on Thursday I had Acrobat and Photoshop open, also iTunes and Mail. I generally use Facetime these days but on Thursday (I haven't used my Skype account for 18 months) I did install the latest version of Skype as someone required a Skype call with me. The software installed okay and I had the conversation with the person though the camera feature didn't work my end. I do wonder whether installing the Skype software has done something to the iMac. However, I don't see that it would stop it starting up completely!

ITunes :: 10.6.3 On OSX (Lion) Crashes On Startup

Jul 6, 2012

Since the last software update my iTunes no longer runs when I click the icon on my dock or in the Applications folder. It crashes after about 10-20 seconds and never displays a window. I've pasted the log below. If I run iTunes from the command line it opens. I get a complaint about a Quartz visualizer plugin not being for the correct architecture, but otherwise it runs totally fine. If I have clicked on the icon that makes iTunes not open before I run it from the command line it does verify/check my library which takes a little while, but otherwise once that is done all is well.

Software :: Safari 3.1.1 Crashes Immediately Upon Startup

Jun 19, 2008

I recently upgraded to Tiger and started using Safari 3.1.1. It was working great for a few weeks until I installed a 3rd party add-on. Safari now crashes upon startup within about 7 seconds. I removed all files that this add-on had installed and I tried re-installing Safari 3 and even tried to install Safari 2 to see if that would work, but no go. If I click on anything it will start beachballng until it crashes. I was wondering if someone could give me a list of all the files that have anything to do directly with Safari so that I can delete them all and reinstall. Also, if there is anyone who would be willing to look at a crash report for me to try to figure out what is wrong.
