PowerPC :: Unable To Start System After Update / File System Got Corrupted?
Jul 19, 2007
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.....
System will not start. I now have OS Lion. I can not use the start up disks as adviced by others. My start up disk is OS Snow Leopard. I installed OS Lion. What do I do now?
The Snow Leopard start up disks tells me "Mac OS X cannot start up from this disk."
A friend of mine has a G5 iMac that won't start. When you press the powerkey it tries to start, the power light glows, the screen goes grey and after a while the fans start whirring. Occasionally (twice in the past couple of days) it has started up, but it froze after a while. Other times the apple logo appears and the gear wheel starts turning but then it freezes.
I have tried booting from DVD, holding down the shift key and have taken the back off and pressed the wee button on the board.
Since my friend has the same model of iMac as me (they were bought at he same time and place) i tried the RAM that I took out of mine when I upgraded.
I had a mirror drive G4 1.25g, 1.5 g ram since it was brand new and it had problems from the start that just got worse over time. I still need to use it semi-regularly and so I would like to know if anyone here might have a clue what's going on. Of the long list of problems, I'll describe the ones that are the most frustrating! oh and by the way, I zapped pram and I have reinstalled everything from the original discs which made no difference at all.
1. When booting into 9 or classic, just about every other time or so I'll get a system error and I need to hold the power button to turn it off. Then I need to boot into X and replace the system file in the classic system folder (I already have a copy just for this purpose on the desktop) and then it will boot ok on the next run. 2. If I boot (9 or X) and don't touch the mac at all, it will hang up after about 10-15 minutes. If I reset and boot a second time, it won't freeze. So my practice for years has been: boot up, wait for the desktop to appear and restart immediately. 3. Many (but not all) applications fail to launch with an error (quitting unexpectedly), i.e. don't run at all. Some launch ok when the application is launched but quit when they're launched via a double click onto a related document.
How does that sound? Is there any hope for this machine at all? I would be eternally grateful for any solid pointers just as I'll be forever mad that I did not return this machine while it was still under warranty!
Today I tried opening my keynotes presentation file to make amendments to it and when I double clicked on it, the program loading bar only loaded up a third of the way and then hanged. I then tried to save it to a flash drive and use it on a different computer, but when I tried to copy it over to the flash drive it gave me this error: "the finder cannot complete the operation because some data in "garment styles" could not be read or written error code - 36".
I have tried changing the file extension to a zip, then unzipping it and then renaming it but that did not work.(It wouldn't let me unzip it). I have also looked at the index file name to see if that was the problem, but that is as it should be.
I have also tried uploading it to a website and emailing it and it will not let me.
Is there anyway I can recover this file as I have been working on it for over a month and it is due next week, or will I need to start again?
My parents recently bought an iMac. Yesterday my mom was playing a game when the computer froze. Neither force quit or holding the power button was doing anything so in her frustration she unplugged the system. Today, after plugging in the system again, it won't turn on.
I press the power button on the side of the wireless keyboard and the green light on the keyboard turns on for about 3 sec and then starts flashing. No fans start up and the screen does nothing.

I was asked to performed a system update with a reboot which I proceeded to do. Once the reboot was complete I had lost my system time (which had been reset to December 31, 2000 and my background had been replaced with the original generic MAC background. I have been unable to find the source of this issue and I am unsure how to fix this. I was able to change my clock by adjusting the Date & Time Preferences and fix my background image as well, but I am concerned that this is a temporary fix. Has anyone else experienced this with a system update?
I am new to macs. I clicked "software update" and it downloaded 9 things. everything from iworks 09 to itunes and mac os X update. After it downloads it says "some of the selected uopdates could not be expanded and verified. it may have been corrupted during download etc. The update will be download and checked next time " I have done this like 5 times in a row and the i get the same message. Since I am new to mac I have no idea how to debug this. Can someone tell me what I am supposed toi do now? . Also if i uncheck all except one (like imove) I get the same message about the file being corrupted. When I check only tghe mac OS X update and it then asks to restart the computer, it again gives the message saying an unknown error has occurred and it couldnt be installed.
Just bought a second internal Hard Drive for my Dual 2.5GHz PowerPC G5 machine. Simply for storage, so no system apps are going to run off it. I've researched enough, can't seem to find an answer in writing. Hopefully this is a simple question to answer...
Basically the HDD is a Seagate Baracuda SATA drive. You know how the old IDE drives came with a jumper pin that you can switch from Master to Slave? Well, it appears SATA drives have an option of 1.5GB/s or 3GB/s instead. (News to me! A personal first internal SATA install!) I certainly know what that means, just curious if I want the jumper capping my speed at 1.5GB/s on this specific older Mac model or if I should simply open it up to 3GB/s.
For the time being, I've left it capped at 1.5GB/s. It makes sense that the system BUS would be the definitive capper of HDD throughput...such is why I'm asking if there's any benefit of opening it up, or leaving it capped.
System Preferences (or Finder) in OSX 10.6.8 appears corrupted - mouse will not activate any commands within any preference, close Finder windows (or open apps with a double click as it used to). No joy rebooting or resetting PRAM and NVRAM.Â
Preferences within another user account on the same iMac however appear to be working OK.Â
I have had my MacBook for almost two years and the battery had just died on me. So I sent it back to Apple and got a new one. But ever since switching over to this new battery, my computer has had issues starting up. A grey screen fades into white and the Apple logo never appears. The computer will just stay like that for hours. A friend suggested turning the power off and back on, holding apple+ctrl+P+R, which worked. However, the next time I turned my computer on, the screen stayed white again, without an Apple logo. Can you tell me what the deal is? Should I bother reporting this to Apple? Is this permanent damage I'm going to have to go thru everytime I start me laptop? Any way to fix it? Thanks.
System Preferences appear corrupted within 10.6.8 - mouse will not activate any commands within any preference and will not close Finder windows (or initiate apps with a double click as it used to). Have tried rebooting and resetting PRAM and NVRAM.Â
Another user account on the same machine appears to working without issue. Think my young son may have dabbled with system preferences after he downloaded Minecraft last night.Â
could not be sure whether the Admin user - password reset with the CD would be the solution to my question as suggested in previous threads I searched - and have no idea where my start up install CD is
So my question-
I was trying to put parental control to ask for password when my computer starts up. I did something I guess and messed up the info.
I can log in with my own account when I restart my apple - which says now it is a standard account (must have messed that up)- but can not make any changes on system preferences or anything else that requires login and password. It requires Admin info. My own login that I use now used to be my admin so do not have any other info set.
now on system pref - accounts - an account titled "test" seems to be admin but can not even access that and reverse myself to be the admin since I can not unlock system pref. Or cant click on "Login Options" for the same reason.
There are no other users on this computer than me.
I wasn't paying attention when installing the windows XP and I choose the "Leave the current file system intact" option and I am unable to boot up my IMac. Its a black screen saying failing to boot from cd, press any key to reboot and it doesn't. I have ejected the cd and I been trying to hold down the option button to choose which to load up from but it doesn't work. I have an external hard drive that I been using for time machine, is there any way I can boot up from that disc and then have the hard drive in the IMac reset to the mac OS X partition? Running Mac OS X Leopard to its fullest updated on Intel core duo IMac with 2 gigs of ram
I am having a problem with symbolic links getting corrupted. I have a new Mac Pro running 10.7.3.
I have defined symbolic links: /Users/walker/G2S -> /Volumes/L2A/G2S [this is pointing to a different partition on the same JBOD RAID] /home -> /Users
The second link was created after unmounting /home and removing it from the /etc/auto_master file. Both symbolic links worked for several days. But then for some reason, without a reboot, the links became corrupted: > pwd /Users/walker > ls -al G2S lrwxr-xr-x 1 walker staff 16 Mar 24 03:08 G2S -> X??G???GÒ?G???G > cd G2S G2S: No such file or directory.
Same nonsensical definition for /home link. I repeat, this did not happen after a reboot. It first happened on /home. I thought that might have been related to a new OS handling of the "/home" label. So I deleted the /home link and did a clean reboot. The G2S link was created after that reboot, not before.
After the above two problems happened, I created a new symbolic link: /Users/walker/G2S2 -> /Volumes/L2A/G2S
I then did not use this new symbolic link in any of my processing scripts. A few weeks went by, then this link somehow got corrupted too: lrwxr-xr-x 1 walker staff 16 Apr 2 17:22 G2S2 -> G???G1?Gu?G
How symbolic links are managed on a Mac (any process that controls their linking?), or For example, could it be due to bad RAM? I have 32 GB.
I just got a Power Mac g4 from my school and i dont know much about it but it didn't come with an operating system. I bought a full retail version of mac os x and pop the disk in and it will only eject the disk. I tried holding option when its installing but the computer wont recoginize the disk it will only eject it.
Any ideas ? when i switch my ibook on it says that the date is set to 2001 or earlier and so i need to change the settings. I can't physically access the settings
My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
I was wondering if there is a small file size limit to the FAT32 file system. I recently picked up a 1TB WD external with Firewire (pre-formatted FAT32) and have been transferring movies and such fine, but I just tried transferring an HD movie (5GB) and some large .dmg's/.iso's and they all just fail with an error.
Is this a size limitation, and will i need to reformat the drive to fix it, or is there something else I'm missing?
When ever I copy some files or create a file in my external USB drive which is a FAT32 one. file permissions are not preserved. All files/folders has 777 are permission. Is this how it work in mac or am I missing something?
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,
While copying files from my digital camera xD card onto my mini, the Card reader un-mounted itself and remounted its self several times, I have no idea why...Now I have a load of 0Kb files in the folder where I was copying to. I can delete these, but they come up with a "file in use" error message so I need to click for each file to be deleted... ~350 left I did try a restart thinking that may clear up any "pending" file transfers from the system to allow them to be deleted like a normal file
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.

I have a 2006 Core Duo MacBook. I shut it down the other day and nothing unusual happened. But, now when I push the power button there's no response at all. Nothing. No lights, no response, no chimes, no screen flicker.Yes, I've read all posts I can find on this and nothing has helped. I've followed the SMC reset (http://support.apple.com/kb/HT3964) and can't zap PRAM since it doesn't even chime. Battery shows a full five lights and the MagSafe cord shows a green LED. I've tried all sorts of booting with just battery, just power, leaving both out overnight but can't get any sort of response. I don't hear any fan motion or HDD whirring up. The power button doesn't seem to be stuck though--it's flush with the case and still gives that slight tactile "click" when depressed. I checked that the RAM's set properly.
I have a G5 Dual 2.5 and the power light on the front (white) is lit but nothing happens when I press the power button. I was trying to reset the PRAM manually by pulling the battery and inplugging the unit because my startup shortcut keys were not working. I had seen it recommended to reset it by pulling the battery and reinstalling in other threads. I put the battery back after about 15 sec and plugged in back in. Now it wont start up.
I was using my Mac normally. I tried to open iTunes and got an error. I decided to restart the computer. Restarting was going normally, but at the stage of entering username and password, Mac tells me that my startup disk is full. I proceed, Mac recognises password and it gets me to the regular screen and mouse arrow appears. Nothing happens then. No icons, prgrams, nothing. I can't delete anything as I have no icons. What should I do? I tried rebooting few times but get the same thing.
I have a late 2008 2.4 mhz 15 inch MBPro with 2 gb of ram (1+1). I have one recently purchased 2 gb ram chip to replace one of the 1 gb chips so I will have 3 gb of ram (1+2). The MB Pro will not start with the 1+2 in. Do I need two 2 gb chips for the new chip to work?
