Sep 26, 2008
I have a 1,25GH eMac G4 and it has a problem. When I try to boot it crashes. or it loads the OS 10.4 and freezes after 30 minutes or so. i've zapt the ram a few times and then it started up again as it should.
but then i had to reboot again and it had the same problem all over again only the if i zapt the ram it didn't work anymore.Now i know for 95% sure that it's the memory module, but i've replaced the old one with 2 new modules and for a few times it did great but then the problems came back... I want to have a working Mac again

I have just tried to install windows 7 released version 32 bit in a Boot Camp partition that was running XP just fine. I cannot complete the install process as I get a momentary BSOD and then the sytem goes into a never ending restart cycle. Will not boot in safe mode. Repair utility does not run. I have tried a fresh install 3 times. Anybody with ideas? This is on MacPro Dual processor about 3 years old. Plenty of RAM and HD space. MSFT support in India tries for 2 hours to help and then punts.

running OS X 10.5.8 on a MacBook Pro. Lately my mac has been buggy, and I'm not sure why. When a decent amount of information is processed by any given application, it crashes. These crashes have included Mail, Safari, Photoshop, Foxfire, etc.. even the entire computer has shut down. Using the reset option does not help. I ran Repair Disk Permissions and it always fails. I get messages like "The Underlying Task Reported Failure on Exit". I wanted to try to run repair disk through the install disk but I cannot access it. I have Disk 1 in (Maybe I'm supposed to use 2?).
When booting I tried pressing 'C' and would eventually would get the "must restart" gray screen. I then tried pressing "Option" instead, selected the Disk drive, but the loading screen with the apple just kept going for about 20 minutes and I finally gave up and restarted. There were no longer any disk attempt whirring sounds.

My parents bought my younger sister a new MacBook a couple of days ago. She wanted me to install Windows on it so that she could play some games that she has.
So, I ran Boot Camp assisstant and installed Windows XP. XP itself runs fine. However, when I put in the disc from her MacBook that installs the Boot Camp drivers it gets to about Cirrus Audio (or something) and then crashes to blue screen. I tried installing the drivers a couple of times and then tried to reinstall XP and try again.

I am trying to create a partition with Boot Camp and install Windows XP SP2. Whenever i try to create a partition, the kernel crashes and i need to restart my whole computer, boot up from the OSX CD and then "Repair Disk" to get the lost hard drive space back. I had partitioned my HD last week, but then removed it, but now when i try it, it always freezes the computer. is there any way to solve this problem without my data being lost?

I'm a film composer in the middle of a deadline, and my G5 crashes won't boot again, only get grey screen with Apple and spinning logo.Boot from Applecare disk, run tech tool, hardware fine, disk is corrupted. Catalog B-tree stuff. Cannot re-build without destroying data.Of course I have a clone of my system drive and try to boot from that, but IT is corrupted too of course!Go to Apple Store (I have ProCare), then run diagnostics and find the same. Advice? Wipe the drive and start from scratch.I do just that. I own about 35 plug-in instruments for Logic 8, so it took two days. The same thing happens. Disk won't boot.

I have a late 2009 Mac Mini with 8GB of OCZ 1333 RAM and an Intel X25-M 160GB SSD. Running 10.6 fully updated and installed from scratch.I have been getting out of the blue crashes while the system is most of the times idle. Can it be the RAM? It's reported fine as 8GB 1333 DDR under the system info. The Intel SSD runs latest firmware.
This is the log from the last crash which happened a little ago.

Yesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.
So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.
What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.

I have a 2 week old iMac 27", i7, 2tb Hard Drive, 16gb RM
In the second week the boot up times became very slow.
I would turn the machine on and get the chime within 5 seconds or so.
Then just a black/blank screen.
Eventually after about 10mins I would get a white screen then it would boot up normally.
Now the machine just doesn't get to the white screen. So I get the chime and then just darkness. It does sound like the machine is on (usual quiet imac whirring).
I've tried various key commands when I turn the machine on including pressing C with the install disk in the dvd drive and the alt, control, P, R pram reset.
I've also tried unplugging all the cables, leaving the machine for a minute and switching back on. I did manage to perform the PRAM reset once. I reset the machine and it booted fine.
But now when I switch it on just darkness.
I've called after sales and will try to get the machine replaced but in the meantime is there anything I could try that might make the machine work? I need to do a remix this weekend (deadline Monday) so really need to get it working.

I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.
I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc".
I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.

My mid 2010 iMac i7 will not boot past the apple logo? I'm running 10.7.3. I have tried restoring from TM backup from recovery mode (worked the last time this happened) however upon completion it returns to the recovery screen? I made a disk of Lion when I downloaded the first time (followed same instructions sourced from numerous websites) which does not seem to work when i set to start up from this disk, just gets to the grey screen and flicks between the apple logo, a folder icon with a question mark and the circle with line through? Now I can't eject the disk either, a message appears that system can't eject and to make sure all applications are closed? Not sure how to go about closing these applications without being able to start the system? When I tried booting from the Macintosh HD I got a message that the boot cache partition was faulty? I have ran disk permissions etc all ok.

This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

Is it possible to boot from an external Firewire DVD Drive? It certainly isnt from an external USB DVD. Real answers only please, not "I think so" ones based on HDDs or rumours you may have heard!...
Background:
I've got an MCE Optibay in my Mid-2010 i7 MBP. When installing Bootcamp it refuses to install from the external USB DVD drive. In the end I pulled the 2nd HDD out and reconnected the internal DVD. It then worked fine without a hitch. Then I reinstalled the 2nd HDD and all was fine for a few days.
Now I want to resize my Win7 partition (bigger, as MS Visual Studio's bigger than I thought, and I might stick some games on). I can shrink the OSX partition fine with Disk Utility, but windows won't grow the Win7 one because the empty space is before the Win7 partition, not after it. Apparently this can be done with GParted. Guess what? I can't boot the Linux based GParted CDROM from the external USB DVD drive! So, will a Firewire one work where USB fails, and solve my alternative OS booting issues? If I buy one I can then either use GParted, or delete the Win7 partition and start again without having to pull the laptop to bits all over again, only to put it back once I'm done, and possibly have the same issues in the future. Obviously I don't want to blow extra money getting a Firewire DVD drive though if it's a waste of money...

I have an iBook G4 1.07 GHz 30 gb 256 RAM with Panther. It was working fine until my HD got close to being full. Now I can't get it to boot past the Apple screen. It will either freeze there, or move on to the blue screen and freeze before the progress bar enters. I want to re-install Panther but I can't get any CD to boot during startup by holding "C", including the Panther OS CD, the Hardware Test CD, or the Tech Tool CD. I am able to boot to single user mode, where I type fsck -fy, and I recieve no errors with the hardware. I had this issue beore and my HD had to be replaced by Apple.

This is the 1st time i got a Mac , i bought a black Macbook 2.4GHz some days ago .
I installed Windows Vista Ultimate using Boot Camp , and all went smoothly .
Only 1 prob is when restarting , i have to wait too long for the Windows to log on , i think about 1min with the black screen.
And if i want to boot in Mac OS , i have to push down the D button or the Alt, it takes quite a long time too .
So do you guys have any solution to this problem ? I want to get rid of the waiting time, way too much.
And do you know how to make my Macbook jump right in the choosing section when it starts ? ( so that i dont have to push down any button when it starts )

Is there a way to make the Boot Camp menu the default boot screen, as opposed to holding Alt? This is the latest SL release, if that matters.
I know this is possible in some manner, our networked iMacs all do it; they start up and give the option to boot OS X or Windows, with a countdown to boot the default OS. I'd just like the same thing to happen on my MBP.

I have OSX installed on a very old Powerbook. Well it was working and then I left it for awhile and now it is giving me the good old folder to question mark screen (maybe someone dropped it?). Well I'm not much of a mac user so I looked up all of the different boot key commands and tried to boot from my OSX CD. Holding down C did nothing, and neither did ANY of the other commands except holding down option and that key command that restarts the computer (apple, option, shift, esc?). Anyway, I got into the screen that shows your hard drive and all other devices and it actually listed the CD drive so I clicked it and clicked the next arrow. I waited for awhile and then the screen reloaded (as if it was rescanning for removable devices) and then stopped and only displayed the local disk. What is going on?! It only sometimes displays the CD in this screen and the next arrow never does anything regardless!!
I really don't know any of the computers stats but if I were to guess they're pretty bad. All I know is it used to run OSX just fine and then other people used it and now it doesn't do anything.

Last week I finally upgraded from 10.6 to 10.7, but now my Mac Pro (2008) won't boot properly. It'll start to boot with the gray screen and the Apple logo, but then the entire screen goes gray and it just locks up there. However, if I reboot and hold down the Option key to bring up the list of bootable drives that works fine. I've checked my Startup Drive settings and the proper drive is selected. why it won't boot on it's own anymore? Holding down the Option key is getting old.

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

I decided that I couldn't wait for Gainestown and ordered a 2.8x8 MP today. I'm going to get another 8GB of RAM (I assume 10GB in matched pairs will still perform at full speed). My real dilemma is a Boot/Storage solution-I'm moving from a Dual 867 G4, so all my current drives, both internal and external are IDE, which basically means I'm starting over as far as internal drives goes. The G4 power supply gave out so I'm getting this external enclosure to put my old drives into for file recovery. As far as new drives go, I can't figure out what to do. I'll spare you my million iterations of drive configs I've sketched over the past two days.

I have been trying to install Windows 7 (yes, legit copy) to my Macbook Pro the whole day, but I keep on getting this error message saying "Press any key to boot from cd or dvd . . . ."
When I press any key on the keyboard, nothing happens. I know this copy works because I've tried this on VMWare 3. (I'm going to Boot Camp of BIOSHOCK!)
What I've Tried:
Deleted partition, recreate partition and choose the Windows 7 disk as startup disk.

Well I installed Vista Ultimate using boot camp on my 27 inch iMac using 10.6.2 and now I can't get it to boot in OSX. I tried holding the command key when rebooting but it just goes into the windows part. Looks like windows took over. Does anybody know how I can get it to boot in Leopard?

I run SSD/HDD, my HDD in the optibay is broken, I stuck it in a external and it makes finder freeze, it got bumped around too much so I want to put a new one back in the 'correct place' for a spinner, and stick the SSD in the optibay.(I figure the extra 2% of shock protection offered by the orange rubber circle things is worth the trouble of moving everything).
I am also going to buy a WD 3 platter 1TB laptop drive, and I read that they fit fine in the regular spot in MBP's (I'm going to open and measure in a min.)Anyways, there's no BIOS, only EFI, so how to I pick what drive to boot from? with 10.6 is it as simple as holding option down on boot, and picking my 'OSX' HDD, and then it will auto boot from that until I specify otherwise? (I ask because before 10.6 people on here were always talking about how to switch boot drives.)

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.

Have the new 15" MBP with i7 Processor. I had another MBP with a 7200RPM drive and installed drive in the new i7 Mac. Computer was working fine until I installed Windows via Boot Camp. I can't boot to the Mac Partition any more, the partition is there but when you try to boot to it you just see the Apple logo and NO circle. I cannot boot to the install CDs or a bootable external drive. I target disk mode the computer and used another computer to boot using the drive in the i7 unit and it's fine and I can see all the information. I tried booting the i7 into single user mode and saw the following message:
efiboot loaded from device: Acpi(PNP0A03,0)/Pci(1|1)/Ata(Primary,Master)/HD(Part 2,Sig********-****-****-****-************)
boot file path: SystemLibraryCoreServicesoot.efi
