OS X Mavericks :: Recurrent System Freeze And Jagged Lines Through Screen
Jul 1, 2014
I am having very frequent system freezes (multiple per day) then when restart the restart is very slow. Activity Monitor shows TechToolsupportDaemon taking up 99-120% of CPU for extended periods. I have a MacBook Pro 15-iInch, Early 2011, with 2.3 GHz Intel Core i7; 8 GB 1333MHz DDR3; Intel HD Graphics 3000 512 MB; running OS X 10.9.3 (13D65).
I am also having episodes for sudden abnormal graphics with jagged lines, Screen split vertically with multiple horizontal lines. Screen becomes totally unreadable. Then sudden total screen freeze.
I made rescue system drives on flash drive when I first shifted to Maverick, so I could use Disk Utility to Verify and/or repair the main disk. When I upgraded to the next edition of Maverick, my flash drives no longer worked. I tried to upgrade the flash drives to the new system, but there was not enough room. I tried erasing the drives but now I have a flash drive with only a small amount of space, the rest is hidden and locked.
What do I need to do to correct the problem of frequent freezes, and then How can I free space on my flash drives?

I have a 15" Macbook Pro that I purchased 5 years ago. It is getting old, but I replaced both the ram and the harddrive about half a year ago. I have been having problems with the screen freezing for a while now. At first someone told me that my harddrive was probably causing the issue because it had been corrupted. I replaced it. The problem did not go away. Then I was told the problems I was having is software corruption, so I wiped the harddrive and reinstalled snow leopard OS. This did help for a while, but recently the problem has returned. My computer screen froze 3 times in an hour and I have static lines running horizontally across my screen. I have a screenshot example.

I have a 2007 MacBookPro. shortly after installing Lion 10.7.3 and VectorWorks 2011 I started getting vertical blue and black lines across my screen on startup. They remain with in the apple while the computer boots and the everything freezes. I tried all of the usual fixes, recovery, safe boot, reset PRAM, battery, etc.When I tried to boot of a system disc I get a message sating that I need to restart my computer. Upon restart same problem occurs. 2 months ago I took the whole thing apart and cleaned out the guts. Reconnecting all cables back together, I came across, what I think is the camera cable. Since my camera has been erratic, i decided to test the problem with it connected and then disconnected. Connected same problem. Once i unplugged the camera everything went back to normal, until now. The same problem returned. I cleaned out the guts again. This time I unplugged the hard drive to try and boot off the C drive, but still get the same problem. This morning It decided to boot up. I was able to copy my essential files onto an external drive.
Info:MacBookPro, Mac OS X (10.7.3)

I looked up today and noticed that my bluetooth logo had a jagged line through it. I clicked on it and it says bluetooth not available, then I went to system preferences and, now there is no bluetooth icon to click on. I opened spotlight and found bluetooth, but then I got an error saying that no bluetooth hardware was detected. I have the MBP in my sig. Also see attached screenshot. Anyone ever encountered this? My MBP is still under warranty for 3-4 more months. Should I just take it to an Apple store?

I can get Mavericks 10.9.3 working again now after freezing constantly but now it seems to freeze after being inactive or when I stop to go do something. This MacBook Pro worked fine before upgrade.

Just got my new macbook pro last week, been having some problems ever since i changed my ram to Kingston 1066MHz DDR3, supposedly to be compatible with the MBP.
I have experienced horizontal lines of flickering and freeze of my entire system, which requires me to do a hard reset. I have recorded a video of it here.
I have also experienced similar type of freeze, but the screen pixels just cluster together at the top 20% of the screen, much like this.
I have ALSO experienced my keyboard totally not responding when i try to recover from a password saved screensaver!! The mouse is working fine, but the system just can't detect any keystroke input, forcing me to shutdown forcefully again!
I don't have time to send in my MBP as i need to work on it, and cannot do without a machine, any ideas how to resolve this?
May i also know which rams are compatible with Mac?

I just recently got a Samsung P2450H 24" monitor and I've connected it into my MBP with a mini Displayport > HDMI adaptor and with a HDMI cable. I've changed the default setting from AV to PC in the Samsung Monitor menu as recommended by others on this forum, and now I'm getting the maximum 1920 x 1080 resolution available on both Windows 7 and Mac OS with no overscanning issues etc. Everything fits on the screen. However, the text and font on websites looks a bit jagged and a bit blurry on Mac OS and I'm not sure why. If you stand far away, it's not that noticeable, but sitting at a reasonable distance (say 2 feet), you can definitely notice it. It just doesn't look that sharp in general.
People have said HDMI connections don't work that well on Samsung Monitors and I'd be better off with a DVI connection, but I can't see why there would be a discrepancy between the two modes. Which leaves the other reason - that this is an inherent issue to do with all Samsung P2450H models being affected with Mac OS, and not the cable itself? Has anyone experienced the same issues I've just alluded to? Perhaps I'm just being pedantic, but I'm pretty sure blurry/jagged text shouldn't be a characteristic of this monitor.

My Mac stats: Mac G5 DT/1.8 GHz / OS 10.5.4 / 2.0 GB SDRAM with all current system downloads; I bought this Mac new from Mac connection approximately three years ago. The problems I've been experiencing for many months:
1. Seldom, but occasionally my Mac will fail to start up causing me to do a forced shutdown by holding in the power button. If I delay doing this for a while (a minute or two), the Mac fan comes on rather loud. After a minute or so after the forced shutdown, I try start up again and Mac starts up OK.
2. Seldom, but occasionally my Mac 'freezes'/cursor will not move, causing me do perform the forced shutdown as described above.
3. When I wake Mac from Sleep mode, there is a 'pop/snap' sound which is very audible depending on the volume setting I am using.
NOTE: In case I had any defective SDRAM modules, I replaced them with new high quality ram modules.

New Mac Mini 2009, Apps, user and settings imported from a G4 Cube running Leopard perfectly. When I go to System Prefs - Accounts - Guest and I mark the checkbox "Allow Guests connect to this computer" System Prefs freezes with rainbow pizza. Then, no matter if I kill the application or not, the system is death. If I launch new apps from the dock, they bounce a four five times and then stop but the applications don't launch. Not even I can restart. When all the applications closes the system starts a loop of spinning clock wheel - blue screen - clock wheel - blue screen forever. This is the second new Mac that has the same exact problem after importing all my data, and it's 100% reproducible. I returned the first one to Apple cause I thought it was a hardware failure. What I have done?
Repair permissions and diks
Reinstall the system
Create a test user and try from there
Try from root user
System log when I click the guest box:

my name is David Francis and I publish a community magazine in Bowling Green KY. I consider myself fairly adept with computers and technology having been working with them since 1987. I was a full time web developer for 10 years prior to starting a magazine company in 2007. My experience (was) Microsoft (can I say that here?) and PC. I developed ASP websites using SQL databases and I was more or less a MS Partner having invested many years on the PC and the MS Software (lots of money too I should say.) I was "persuaded" to learn the Macintosh by a fellow publisher and friend who loaned me a computer and Adobe software for six months. I must say I reluctant, but realized quickly that I needed the tools and performance of the MAC.
I purchased a brand new MAC Pro in Nov 07 (2 x 2.66GHz Dual Core), this was the same month that Leopard came out and it was included with the new machine. It came with 2gb of ram which I upgrade (MAC certified ram) to 4bg about six months ago.)I immediately installed Adobe Creative Suite CS3 which I purchased as well as Office for MAC, Parallels so I could run Windows (sorry), and a logitech mouse and keyboard............................

My macbook running mavericks froze earlier today with everything but the mouse becoming unresponsive, since then I have tried rebooting in safe mode (which has been fine) and then normally a number of times, but everytime I do I always end up with the same problem i started with. I managed to get activity monitor open before it froze the last time and found that mds_stores is running at 99.9% CPU.
I understand that it is in relation to spotlight but have spotlight set to look at nothing in system prefs.
is there any way I can start up without the system remembering to start the process that is causing mds_stores to run as I feel this is the problem. I have tried quitting the process in activity monitor to no avail.

grey screen no apple followed by blue screen with vertical lines. Graphics and logic board replaced <6 months ago. What to do? I held down shift, it gets HOT HOT and makes noises. (for safety mode) followed by a blank grey screen and blue screen. Then tried the other way (I think it's command alt delete? I don't remember) and it turned from grey (no apple symbol) to blue blank. Then third time, grey followed by blue with vertical lines, not blocky clear lines that you can see if you are close to it.

MacBook Pro, OS Lion

First of all I'm new here so just wanted to say 'Hi', its been great to see all the discussions on these forums and they help a lot with buying tips and troubleshooting so thanks.
Problem #1 I purchased a refurb 24" 2.8GHz imac early May and have been using it since then and so far other than the "normal" gradient issue and a brownish tinge around the edges of the screen it has been good.
Lately I've been using Aperture a lot and first started to notice that in some pictures especially ones with quite a bit of highlights like clouds that there are small hatch like patches in all the pics. I know it isn't the pictures but the imac screen itself as you can see it on the desktop as well. It only seems to be centralized in the upper left hand section of the screen and they seem to be lite purple/blue in color. And like I said its only in patches in certain spots on the screen. Don't know if I'm being over anal about this or is this a problem?
Problem #2 I switched to a solid blue background to check the above problem and notice that there is screen burn in of the top and bottom header in the outline of my firefox window on the blue screen. Between switching windows often and applications very frequently and not leaving the computer at all... what the heck? Not normal for imac screens is it? Heat issue causing burn in? Hasn't been an issue with any other LCD I've ever used.
By the way the imac came in a new white box and was wrapped like new in perfect condition but I popped it open without ever starting it once to make a hard drive swap and the thing was definitely a bit dusty inside so in now way was it just used for a couple weeks before being given back to apple.

I have 5 external drives... They are Seagate and Western Digital Drives. The worst of the bunch is the Western Digital My Book Studio Edition (1TB) that I have connected via FW800. The 2nd worst offender is the Seagate 750GB Free Agent connected via FW400. The most dependable appears to be a Western Digital USB drive, but it's the slowest performer. The issue is this: I either have a freeze up that requires an unplug from the Mac as well as power, then re-mount to get working again, OR, when I start up the Mac, it just hangs at the 'apple' and never fully boots. I have to unplug the drives and boot, then plug them back in after the boot. It's getting very frustrating. Do you all have a successful setup with external drives?

I have a MBP running Snow Leopard. The keyboard and trackpad became unresponsive, even though music was still streaming through Google Chrome. So I held down the power button to force shutdown. When something like this occurs, is there anything that should be done upon restarting the system again? Any general maintenance, system checks, etc? From my experience with Windows, not infrequently after similar scenarios, forced shutdown or crash, upon restart it'll automatically go into some type of disc scan. I wonder if anything similar occurs or is necessary with OSX. And lastly, when the system freezes like in my instance, if that's considered a freeze even though music was streaming all the while, is holding down the power button the only resolution? Are there no other safer alternatives to attempt first?

My mac screen is frozen with white fuzzy lines going across the screen. I shut it off and turn it back on but it still remains white fish lines on the start up screen. I've tried revolting it, it works sometimes but now its stuck at the starting screen. I have been at this for 2 hours to try and fix it but nothing has changed about the screen.

My iMac has been running very very slowly for about 2 weeks. I am talking very very slowly. It seems to be processing time. I will be in word, move the cursor and it will take a few seconds to get there. Sometimes I have to wait a minute after I click on something for the cursor to catch up, and (hate to say it) even 2 minutes. That's like a millennium in Mac time.

My computer (24" 3.06Ghz intel core 2 duo) won't start. When I try to turn on or restart my iMac I get vertical rows of pixelated lines across my monitor on the white startup background with the apple logo and it will either freeze up or the background turns gray and I get a message that says I should restart my computer. This has also happened when restarting using the Apple hardware test (which doesn't report any errors).

I've seen so many posts about this, but with the limited time I have between system freezes, in desperation I come here. I'm running Leopard 10.5.8 on desktop IMac. I have plenty of memory, but don't know how to check the hard disk space (I'm an ubernoob). I've run a couple of the mac maintenance programs still to no avail. I get intermittent SBBOD where NOTHING responds and have to do a hard reboot. Doesn't matter what applications are up, as even startup is very slow when in SBBOD mode. Rebooting, then, doesn't resolve the issue. It runs fine when the SBBOD is not present.

I was browsing the internet on my '08 iMac when the system suddenly froze immediately followed by the screen turning to nothing but vertical lines. I fear this may be an issue with the graphics card, but would anyone be able to offer any further insight?

never had a problem with a freezing mac in 5 years of mac use so wouldn't like it to start now. Whilst using firefox this morning it froze, force quit wouldn't work, entire screen froze. Keyboard shortcut wouldn't allow me to shut down, so I had to shut down via the on/off switch.
When I came to switch it on again it loads up to the log in screen, the mouse moves around the screen but when I click on my username nothing happens. I've taken out all USB cables, switched wireless keyboard and mouse on and off etc, restarted, no joy. Next I tried to startup with the c key and install disc, but again I got to the log in screen and nothing happened. I'm assuming as I can't log in and get to a desktop that is why it's not allowing me to start with the disc?
