Mac Pro :: Getting Strange Designs And System Freezes On Boot Up
Jun 9, 2012
I was using my mac pro 3.2 octo from 2009 without any troubles. Recently it started giving non stop trouble. I have 2 gb ram from the factory and another 2 from 3rd party. My problem is when I boot my mac I am getting some strange vague designs and it freezes. I tried shifting the boot hard disk from slot 1 to slot 2, booting with either set of ram, changing the graphic card slot etc.
Info:
PowerMac, Mac OS X (10.5.6)

On my 1st Gen Mac Pro, I suddenly get a strange blue screen out of no where. Everything on the screen freezes for a few seconds then the screen flashes blue for another few seconds. After the screen comes back from the blue, everything works perfectly again. Even when listening to music, music pauses for a few seconds and then comes back. This happens a couple times a week and its getting on my nerves. Sometimes it lasts for a long time and requires a hard restart.
I have tried reinstalling Leopard/tried hardware test/upgraded to the 8800GT video card and the 3870/I cleaned the whole inside of the box with compressed air. I even took her into the apple store and had a genius look at it over night. They told me everything is working perfectly. Ofcourse it started doing it again after I got home with it. The apple store suggested that I could always replace the logic board but they want over $1000.00 for that and I dont know if its worth it.

My dads MacBook Pro started acting weird first the screen would freeze up and the cursor could still move but there would be about an inch wide black line that would follow on top of the cursor wherever you moved it.
We thought it was a software problem so we booted it up off an external drive and it did the same thing after a few seconds of loading the finder, now it won't even boot, it loads the white screen with the apple, then it stops at the blue screen where it usually shows the loading of everything, once in a while it will get past that but it freezes with black lines over the cursor.
I've tried zapping the pram and i've held the power button down till it beeps i've also reset the pmu, so im out of ideas.

I have a mac pro running leopard (purchased in 2/08) and it was running beautifully for almost 2 months with no hangs, crashes or freezes. Then, for some reason, today when I turned it on, it would not boot. It would get to the apple logo, then just sit there for a few minutes, then reboot itself and the same thing would happen. I pulled out the ethernet cable, unplugged all usb except keyboard/mouse and it would then (sometimes) boot into the system, log me in and present me with the UI.
I then quickly performed a soft reboot and it would get to the desktop. However, I can only use it for anywhere from 30 seconds to 5 minutes before it would completely lockup. The clock freezes, the mouse freezes and it just sits there forever. I have tried booting into Vista (BootCamp) and it also freezes before startup is complete. If I hold down Option and then select the System disk, it will either just hang forever or get to the desktop and then freeze again....................

Since a few days ago my Macbook Pro 13" from last June started to freeze randomly for atleast 30 seconds and then it would come back and most of the time freeze again after a while (in OSX only it seems, Windows 7 I did not have such problems, though I didn't use it often). Sometimes it occured frequently, other times it didn't and this morning I had the same thing again, I just held the power button and shut it down, did this two times in a short period of time and when trying to boot it for the second time all I get is a gray screen with no Apple logo or anything.
Searched the forums, tried the install DVD and C button to no avail, same thing with trying to reset the PRAM and NVRAM...Is the logic board broken or anything? I don't understand how this could happen...And if I do take my laptop to Apple, should I remove the Intel SSD drive I got in it right now and put in the stock?

My PowerBook G4 has been slowly dieing over the last couple of month, ever since I told it was going to get replaced with a MacBook Pro early next year (hopefully around MacWorld). The Airport signal is slowly decreasing and I'm in the same room as the wireless router, the mouse touchpad in parts is loosing sensitivity, there are randomly hard freezes of the system, etc.
But over the last couple of days I have noticed a strange noise coming from the fan (well that's guess), it sounds like its sighing, I know it sound ridiculous but it's the only thing it reminds me off. It comes and goes (the sighing) but it is constant and it's really starting to: 1) Freak me out that my computer could die and day, 2) Annoy me. I have a sound clip (.amr - also converted to .mov) does anyone know how i can upload it onto here or a link, so people can hear what I'm experiencing.

I'm about to get my brand new MBP in the mail and was wondering the best way to make it individual on a budget with little technical experience. I've seen some MBPs with interesting artistic designs on the back of the screen and was wondering where to buy those. Not a full color stick or anything like that, just the simple white design. For example, Kevin Rose's MPB with the DIGG logo etched in or the Ad MBP with all the different companies names etched in. I want something simple and stylish like that, only more artistic and less advertising (e.g. no words).

I've been reading this site for a while now, first time I'm posting. I recently purchased 8 GB of RAM for my 2010 13" MBP. There are two 4 GB DDR3 PC3-10500 1333mhz sticks. When I install them in the laptop my computer does not get past the apple logo boot screen (the spinning disc freezes). However, I can boot into Windows (boot camp) without issues.
Also, when I pair either of the 4 GB sticks with one of my old 2 GB stock sticks the laptop boots up fine in OS X. The system profiler registers it as 6 GB of 1067 mhz RAM (the stock sticks are 1067 mhz)

My (new) iMac makes a strange noise when I boot. It looks like the hard disk to me. As long as it makes the noise, it doesn't boot. After the noise is gone (sometimes in a minute, sometimes five). I have attached a file recorded with my iPhone to illustrate what I mean. Is this normal or should I get back to Apple?

Roughly two weeks ago I started noticing all kinds of unfamiliar system files showing up in a number of my folders. They are always grayed out and as far as I know have nothing to do with the actual folder. These are just straight forward folders and/or my actual Mac hard drive. Any idea where they may be coming from? I don't know that any of them are actual system files that might be important. The second link, the CODES folder should be the only file in that folder. Here are links to a couple of them. [URL]..

ive had a look around an only found bits an pieces relating to this but nothing really specific.i have an imac 3.06ghz, 4gb memory. less than a year old its been making some noises recently (like a downloading sound for afew seconds every so often) which happens every 30 seconds or so. this happens even when theres no programs open and im not connected to the internet!!! ive only really noticed it doing this the last month or so to be honest.
the computer has also been re-formated about a month ago as it was passed onto me from a family member, an im wondering if its got anything to do with that?is this a normal thing for macs an maybe i just havent noticed it before, or does it sound like something is wrong??

I had a 2008 24 inch imac (3.06ghz C2D) and had some issues with it. First the hard drive failed, upon bringing it into the Apple store, they told me that they replaced the hard drive and screen (due to dust under it), however, this was not the case. What they had actually done is replace the entire unit and gave me a refurb which was previously registered to someone else (as evidenced by the registration info). A few months later, I had another issue, this time the logic board had failed and I once again had to lug this 20 pound beast through the largest mall in the city in order to get it to the Apple store (for the second time). I politely explained my discontent with this whole process, they did not inform me that the unit was a refurb and now it had failed yet again. Much to my surprise they offered me a replacement in the form of the i5 with a 1tb drive, 4 gigs of ram, the works. Now here is the problem: I was not given any of the included dvds as they do a "like-for-like" swap only. This is now an issue because I can not install Snow Leopard from the retail dvd, nor can I install Leopard from my previous iMac disks. In addition to this, I do not have the correct drivers for a boot camp install. Thus I am stuck if I ever need to reinstall Snow Leopard or if I need to utilize boot camp (which I do).

I have a Macbrook Pro, one generation old. In the past week, it started making a high pitched noise from the upper left hand corner, near the keyboard. When I pick the computer up and change the angle, I can eliminate the noise.
Just in the past day I noticed that in addition to this high pitched noise, periodically a much louder, different noise comes from the same area, which again, if I move the computer around, I can minimize the noise.
My guess is that there is something loose in the computer, maybe a fan? Should I bring it to apple? My computer has been running pretty slow lately, could this have anything to do with it?

I recently took the plunge and installed Lion after being content with Snow Leopard....well now I have quite a few issues. When I open system preferences for some reason it automatically opens to Network...why I'm not sure. When I click show all, then click sharing, I can't make any changes in the Sharing preferences without my entire system locking up. I can't force quit or anything. I can still use the mouse but all I have is the rainbow wheel!
I have searched and searched and haven't been able to fix it. I have tried booting into the Guest account and the same problem happens there. I have trashed all the plist files everyone says to try. I have tried repairing permissions etc. I feel like I have tried everything. Is there anything else that I can do without have to do a clean re-install. I'm hearing if I do this that I won't be able to migrate my files from by backups due to permission problems?
I also took a look at my system log and it is full of this!

I have a June 2010 17" 2.66 i7 UMBP. This is going to sound really silly and I do not really know how to describe it correctly, but it has begun to make lots of strange "Tapping/Clicking" noises. It happens quite regularly when the notebook is stationary but increase whenever the notebook is moved.
I am familiar with the hard drive clicking noise but this is totally different - it kind of sounds like a small metal ball-bearing inside a small, thin glass sphere knocking or clicking against it's side or like tapping a small thin glass object with something like a thin metal rod.
I am sorry for the poor description but that is the best way I can describe it & know I must sound like a complete idiot but I am not very savvy to computer issues but I hope someone can identify what these noises are if if they mean that something bad is going on.

Hey guys, got a little issue here. I have had a MBA since about march of this year. Just recently I on two occasions the computer has all of a sudden had this loud high pitch whine. It has only happened twice and at both times (if I remember the 1st time correctly) I wasn't really doing anything on the computer. Today specifically it was just sitting idle on my desk. Not sure where its coming from maybe speakers? Any idea to what this is? Should I be setting up an appointment to see a Mac Genius?

fonts must be messed up in Snow Leopard. Some system things display strange fonts. For example, my user name in upper right hand corner of the screen doesn't look right.ALso, the font on the "tabs," in Safari is not correct, and I can compare it to other SL computers.

I was working with logic pro 8 on a project when the APP crashed. Then, the whole computer became real slow. I couldn't open anything without getting the spiraling rainbow circle for at least 3+min and even then the app wouldn't launch. So I shut down normally, which took a while.
After I left it off for about a min or so, I tried to boot again just to get stuck on the gray screen with the apple logo. I did some research on my phone (since I currently don't have internet because I'm moving this week) and found out how to reset the pram. I tried it, and this time it got all the way to the blue screen where it got stuck. I tried resetting the pram a second time to finally get to the log in screen but everything was going very very slow. Unusable type of slow. Opening a new finder window took at least 2 mins and everytime I ran my mouse across the idock, it would freeze.

I have done some research on triple boot systems, and it appears that a third OS must be run virtually, but all the information I came across was a few years old. Microsoft is running a deal right now on Windows 7 for students so I would like to pick up a copy and try it out.
Is it possible to run 3 operating systems through Boot Camp 3.0? I am not interested in running a virtual OS.
Current Setup:
13" macbook pro
Snow Leopard and Windows XP through Boot Camp

Just an FYI. Tech Support at Allsoft states The Disk Warrior 4.2 Boot DVD will not Boot the new 2010 MBP's. They are waiting for information (software) from Apple.
Will need to use Target Mode or another Mac connected with Firewire till then. Boot from that then run DW from your MBP.

Over the last few months I've noticed a trend with my dual 2GHz G5 at home, it often locks up and the fans go full-throttle. It sometimes happens when I'm using it and often when I leave it idling for a while. I've noticed that the CPU A and CPU B temperatures start around 120 degrees F when the machine is first powered up and steadily climbs to around 150. Is that normal? The dual 1.8GHz G5 I have at the office doesn't run hotter than 110 degrees. The fans haven't failed. Is there a coolant link? Is there anything I can do to diagnose this, or do I simply need to call AppleCare?

Right now I'm saving for the 20" model (2.66). Would The 20" 2.66 iMac Freeze Like The 4850 Issue? Will it freeze like the upper model with wi-fi on? Making sure before I invest in an iMac.

I recently upgraded from my Macbook to a refurbished Macbook Pro and since the day I got it it has been giving me problems. Applications quite suddenly all the time and the system freezes and runs sluggish. The biggest prob is the display. It goes black and won't come back on. Sometimes when it goes blank you can see faintly if you look carefully and you can hear sounds. It slowly deteriorates from a once a week occurrence to a daily one until it won't turn on at all. I reinstall everything once a month. I took my computer to the mac store they ran all the diagnostic tests they have and said it is not a hardware problem. I have now wiped out all of my non-apple applications and the problem is back.

My MacBook was working perfectly until a couple days ago, when it suddenly started hanging every time I booted it up. I gave it a day, and managed to complete some software updates the next time I logged in, after which it started working fine again. Now, however, it KEEPS freezing every ten seconds no matter what I'm doing. The worst part is, it freezes for about five seconds (the pointer becomes a pinwheel, which keeps rotating, as if my laptop's processing something), and then it starts working again. I ran a virus scan to no avail, and have rebooted my MacBook countless times. I don't know what's wrong with my laptop

My beloved iBook 1.33 wont boot, has flashing? and freezes when I try to boot from original CD with a bunch of vertical lines. I ran the diagnostic DVD and it says Invalid memory access. I removed the external ram chip for computer and still get same error. I also zapped PRAM, reset NMVU (whatever it's called). I already have the iBooks case open and willing to try anything.

I have downloaded the RC version of Windows7 64bits. I burned a DVD with 1x speed but when I tried to boot via DVD (pressing option key) it shows 2 option for DVD, Windows and EFI. I tried both and none worked. The Windows version starts and a DOS menu appears with 2 options which doesn't show what it is and then it freezes. The EFI option freezes imediately on the boot screen.

Say an app has crashed and I then bring up the force quit dialog. I then select the app I want to kill, and press the force quit button. Now as the little popup that says "Are you sure you want to force quit" is coming down, my machine freezes. This has happened 3 times exactly the same way. Other than that, the machine is smooth as clockwork. I'm kinda thinking there is some sort of GFX card bug or something?
