Mac Pro :: Start Up Not Reliable & Occasional System Freeze
Jul 22, 2008
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.
I bought this G5 with consistant startup problems but after replacing the hard drive,installing a fresh operating system, re-seating the ram, checking the Pram battery, etc, it was running fine. I now realize that when trying to repair the disk permissions, the same list keeps coming back even though it shows it's been repaired. Also, occasionally it may freeze or go into kernal panic on startup. If the hard drive is new, does it sound like a possible hardware problem? Does repairing disk permissions involve anything hardware?
I bought my first uMbp the day Snow Leopard came out. Unfortunately, it was not installed on the uMbp. So upon running the mbp for the first time, I proceeded to install SL.
Now occasionally, maybe a once every other day, whenever I open up a few applications like Word or maybe even a new tab in Firefox, everything would freeze and the spinning color wheel would spin for about 30 or so seconds and everything would resume to normal.
Now I ask, is this normal behavior? I have the 2.26ghz uMBP edition with 2gb of ram.
I have a new (6 months old) 27in iMac with a 1TB disk and 8GB of memory. It is an Intel. I bought a new 1.5TB external USB HDD yesterday and formatted using the Disk Utility and tried both "Options" of "GUID Partition Table" and then "Apple Partition Map" because the backup kept crashing. I have selected only the main HD partition which is 55GB. I believe that it should work, however, for some reason unbeknown to me it keeps crashing. Initially, it was around about the 700mb or 1gb size. Then I managed to get to just over 10GB. Most annoying as anybody who has tried to backup with Time Machine must know given its slowness. The error messages say that the disk has been removed during the process which is not the case. Can anybody suggest a remedy or some other more reliable software to backup my system please?
Can anybody advise me as well as to whether either of the following are better than Time Machine Please.
I've received my new mac book pro today. After several minutes the system is freeze. how can I know why?? (I've revised the logs file, but everything looks be fine)
When I've a freeze, I press the power button 5 seconds and then the system is poweroff, but after this I can't startup again. I've to wait 20 minutes.
When I started my computer this evening, it froze immediately after starting up. (I have had three start up items for over a year: Dashboard, iTunes, and Chrome). Then after I unplugged it and removed the battery to restart it (nothing else would work), it was extremely slow to restart. I had to then Option-Command-Escape out of each progrma that starts up, and when I started Chrome again, it was very slow. After some time, it started to pick up speed again, like starting a car engine on a cold winter morning.
I've recently installed Lion on my macbook pro 13" mid 2010. Then it freezed end i never got it back up again. If I start up my mac, the screens just black. Sometimes it freezes when the spinning wheel is visible. If I try to boot with the recovery partition it freezes to. Plus my lion DVD is now stuck in my machine.
Ever since I installed Snow Leopard, once start-up is complete, I am not able to use the keyboard or track pad button for about 3-4 minutes. They are frozen - the cursor/arrow move according to trackpad/mouse movements, but anything kind of button/key input is not registered.
I woke up this morning and my iMac G5 (w/ Leopard) was frozen. I restarted it manually, but it would freeze on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM - any other ideas?
What can I do in Safe Mode that might fix my comp? I haven't recently installed any applications, and I have all "open at login" items turned off.
I've an early 2008 macbook Pro with geforce 8600 graphic cards.Since a few days i've problems with it, during a session my screen become a little green and pink and I've sometime the kernel panic message.When i restart, i've green and black bars on the screen, the apple is not in the middle and the mac freeze.I can't start with the recovery, even on the usb recovery disk, because after the choice of the recovery, the mac begin and freeze.I've ever try to begin in single user mode with fsck -fy command, sometime it resolve the problem but now nothing at all.
I just got the MacBook Pro three days ago. Before, m system preferences were working fine, now when I open it all i get it the spinning wheel. How can I stop this? Force Quit hasn't seemed to help.
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?

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............................
heavily cycled battery began to reveal age when low battery warning stopped appearing. next the battery revealed age by displaying incorrect charge status percentages. finally, the system froze (pointer did not move) so battery was replaced. system freeze continues to plague the Apple iBook G4 with 1.33 GHz PowerPC CPU and 1.25 GB of RAM. how to correct or just recover data from user folders
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 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.
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'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 am a proud owner of a MAC powerbook G4 for just over 3 years now. It runs MAc OX 10.3. For the last two weeks i have been having issues. First it started to be very slow. Then it would not boot up and i got a blue screen. I ran the file system checks from the OS X and it complained about the volume being bad and said it could not be repaired. i decided to reinstall the whole thing and did a complete erase and install. IT booted up fine. The software updater asked permission to update which i agreed.
After the update was over, the software updater had more updates. I guessed that it was probably giving me updates in the chronological order. During a particular update, it gave the blue screen and "please restart" ... and when i rebooted it did not come up... just a blue screen... i verified the filesystem using the diagnostic tool and it again said it was corrupt .... I have done this twice now and i have a feeling it happened when i was updating the same batch of software updates.... sometimes my software updater would crash everytime i launch it.....
so here's my problem- when I installed Snow Leopard recently, I opted to not include X11 as one of the "optional" components, and now I am unable to run one of my old occasional-use applications (assuming this is because I don't have X11 available). what I need to know is whether it is possible to simply add that onto my current SL install or if I need to do a complete re-install in order to gain access to the additional components again.
My 3 week old Mac Book Pro just refuses to start up. It gets stuck on the white/grey screen with the Apple logo and the spinning wheel under, in other words, the machine won't boot up. I bought the machine new with SL installed, had just been working on it, shut it down properly through the menu, went to eat, tried to start it up and now nothing happends. Except being furious and VERY dispointed on such a new machine,
I've been having problems with VLC. When I watch fullscreen movies on my external display (24", plugged via DVI), the picture (along with the sound) occasionally skips just little a bit. This happens about once every minute or two and isn't really that bad
I have a new Mac Mini and occasionally (once every couple of hours) a static pop comes through the speakers. These are Logitech Z-2300s that worked fine without this issue on a Windows PC a couple days prior.
PC user for a number of years. Made the jump to Apple; received my iMac Saturday. Started using it, but don't really know how to navigate.Also, during the initial start up, I took a picture when it asked if I wanted to do one. Where is it in the computer? I would like to edit it.
I am having a problem with my Macbook Pro (OS6.8.8 2.4 GHz Intel core i5). I tried running through all maintenance procedures using Onyx and also tried disc utility to verify disc. Disc utility said to reboot from mother OS and repair harddisc but I can't start up from cd. Tried normal hold down 'C' during restart and also set disc as start-up disc in system preferences but only get a blank screen. The computer when booted from the hard disc (does boot but computer acting 'odd') shows the cd in the cd player and the cd opens so the cd player seems to be working. Also tried an external usb cd player and tried to boot the computer from the cd using this route but get same symptom - just a blank screen and after a short time the cd player stops spinning.
I am concluding that it is not a hardware problem but some software problem that is preventing me from booting from the cd.
Info: MacBook Pro, Mac OS X (10.6.8), 2.4 GHz Intel Core i5
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?
