My computer, a Powermac G5, Dual 2.0Ghz, 1st Edition Released Oct 2003, will just freeze. It usually happens within 5 minutes of booting into the operating system. I am also unable to boot from the Leopard or Tiger DVD's to try and install a fresh copy of the OS as they freeze during the install. This is what I have tried so far, but to no avail:
Resetting the RAM and Graphics Card
Resetting the Power Management (PMU)
Resetting the PRAM
Now this is the even stranger thing. I installed a copy of PowerPC Ubuntu Linux 8.04 and it works fine. This makes me think that it is unlikely to be a hardware issue.
i have an ibook g4, and was using it just fine the other night, then when i came back to it a few minutes later it had shut off completely. now when i boot up, the computer freezes at the spinning gear startup screen or at the blank blue screen immediately after the spinning gear. it will boot in single user mode, but it won't boot up with my os x install disc. does anyone know any unix i could try to use to get my mac up and running again, or has anyone had this same problem and knows a fix for it?
It seems that my MB(unibody 2.0Ghz) has some problem. I recently reinstalled leopard (and some softwares). It takes a little bit more than 2 minutes to boot. Worse comes with Windows 7 beta. I tried both 32bit and 64bit versions. It takes more than 5 minutes to boot! I saw some guy showing some comparison of boot time on youtube. It seems that Leopard should take < 1 minute and Windows 7 takes < 2 minutes (with the same hardware!). My MB takes around 3 times more than other MBs. Where should I start? I recently ran memtest and it turns out to be okay. HDD S.M.A.R.T also reports 'verified'. I'm not sure what would be the next.
I have a problem with my iMac. I have on a second partition lion installed. Everything worked great, but since I updated to 10.7.4 booting needs about 5 minutes. Already checked the partition and the access rights.
My Imac freezes up a lot, usually after 10 to 15 minutes of being on. I suspect it has something to do with overheating. I have to get my data off of the drive before I take it into the Apple store for fear that they will will just replace the drive and all will be lost. I have a fan blowing on it now in the back and am copying data onto an external drive little by little until it freezes up.
I bought it last fall and have a 3 year warranty on it and this will be my second time bringing it in for repair. The first time it was a problem right out of the box when I brought it home and it was replaced. It's a 3.06 processor, 24 inch screen. I am not impressed by the hardware reliability and the all in one system. I am regretting buying the imac after being a PC user for so long and I am using my Windows PC to write this. I suspect the cooling system could be better on my IMAC given the compressed footprint.
This is my first Mac user problem posting going back to my original SE! Power PC based imac running leopard 10.5.8 starts up but then mouse freezes after a few mins. Managed to change sleep mode to 15mins - same problem. Can't boot from Disk as same problem, also command+option and shift all still have mouse unmoved! Obvious change of keyboard and mouse have no effect. Could this be related to offspring's addition of ipad plugged into usb a few weeks back? He tends to unplug the device without ejecting!
When I start up my computer everything looks normal, all icons are on the desktop and my cursor is able to move. The problem is I can't affect any of the icons on the desktop (folders, files, etc)-every thing is frozen. After about 3 minutes it unfreezes and everything then works. what is the problem?
I just purchased my mac book pro on the 18th of may from an apple store, brand new. I decided to upgrade the RAM myself since it is a much better deal, however once I replaced the RAM my computer began to run much slower and it began crashing (showing a gray window that says "please restart your computer" in many different languages) so i restarted my computer and the problem continues, after 12min of running that window appears. I replaced the RAM with the original and the problem still continued. I have run normal hardware tests and extended hardware tests as well as PRAM reset and still nothing changed. Does anyone have any idea what is going on? I'm totally lost on what is going on with my brandnew macbook pro!I should also add, I have been running the extended hardware test multiple times to see if it will crash during that and after 1hr it hasnt crashed yet.
Info: MacBook Pro (15-inch Late 2011), Mac OS X (10.7.4), Lion OS
My Macbook with 4 gb RAM won't boot standard, safe, or Recovery.. All three results in grey screen with apple logo and spinning wheel which freezes after a few minutes. It also won't boot a bootable Mavericks usb with install package. I can boot single user mode and also view whats going on in verbose.. I am including a photo of where the script stops. PS: I've already tried resetting PRAM and the SMC has been reset as well.
I have a emac thats about 4 years old, always has run well and done everything good. Recently retired it to backup computer and did a total erase and instal of the os.. ran great till a few weeks ago when it froze after about 10 minutes of use. Tried it again the next day and got the same thing. I waited a week and then tried it and still...same thing. Unpluged it, hit the power button and waited a day... same thing. Unpluged everying except keyboard and mouse... same thing.
I got a powerbook G4 with a smashed LCD. I hooked it up to an external monitor, and 1 thing keeps bothering me - it lags like hell. I have had an iBook g3, now using macbook aluminum, and I have never seen anything like this on a mac before. It lags like hell - it turns on in about 20 minutes. Sometimes it even doesn't. I have tried resetting Pram, Vram, premissions repair, looking @ activity monitor(nothing exceeding 2-3%). HDD capacity - about 55% full. I cant even describe whats up with it - launching any app takes about 2-3 minutes. For instance, iTunes launching takes 3,5 minutes and none of the songs are playable. I have tried to create a new account - did not help.
So lets start with system preferences. I have : 1,5ghz PowerPC processor 256mb Ram Tiger 10.4.11 HDD 80gb Fujitsu MHT2080AT So at first I though it was the lack of RAM - I bought a 1Gb stick. Now I am thinking it is because of the HDD. But I am not ready to buy another component randomly.
I just obtained an Ibook G4, it was my cousins, and it had crashed, so weeks later he gave up and bought a IMac. Anyway, the Ibook will turn on, boot up like normal. I had it turned on for about 10-15 minutes, and it just powers off. I had it plugged in, and it obtained about 11% battery, so I don't think it dies from battery shortage. Something I did notice, the battery charger cord, from wall to brcik is a 250V wire, while the brick it self needs about 100Volts. It isn't the cord that came with the Ibook. Could this cause the Ibook to shut down?
I have a dead/dying old G4 iBook (logic board failure) and was wondering whether I can remove the internal drive and mount it in an external case, and use it as an external USB or Firewire drive? The drive has some valuable data on it which I'd like to keep, and the iBook only boots for a few minutes each time (if I'm lucky).Is it just a matter of opening it up, taking the drive out, and taking it along to a computer shop who should be able to kit me out?
I have a 1.33ghz 12inch Powerbook with 768mb of RAM, my battery lasts for about 20 minutes, I am on my 4th ac adapter (and it is already broken again, I so get why they made them magnetic in future laptops). I am running Tiger... everything works just fine except the embarrassing battery life and unpredictable charging (b/c of the semi-broken power adapter).
Yesterday I installed Ice Clean and ran a few of the maintenance procedures. This morning when I tried starting my laptop, it started with grey screen and apple symbol, then black screen with white text stating: Mar 13 08:02:44 launched: can't exec /bin/sh for single user: no such file or directory.
I tried contacting Ice Clean, they claim it is not related. I checked my system profile and I thought I had 1gb of RAM it only says 512gb. Could a RAM failure cause this problem? Have started using target disk mode with my old faithful G4 and everything on the hard disk is still intact. Ran disk utility and all ok!
I was installing Tiger using FireWire from my Powermac G4 and it was nearly done when my Powerbook (target) died due to lack of battery... When the Powermac was rebooted, I get only a question mark and flashing smile.
I tried to test the C and T keys holding them down during boot up but only get the smiley face every single time... I even disconnected the secondary drive to no avail.
I recently came into possession of an iBook G3 (Clamshell) model M6411. Unfortunately, I believe it had a cactus HDD - it shows up in Target Disk Mode on my current model 13" MBP but refuses to format or read - locks Disk Utility/Finder up when accessed. The iBook also has NO CDROM drive in it, either (removed by previous owner, reasons unsure). I'd just like to get it to boot to see that everything else works ok. I have a retail install of OS 9.2.1 as well as an iMac G3 OS X 10.1 install CD, and a 10.3 retail disc too.
I am aware that PPC Macs cannot boot from USB CDROM drives, but they can using FireWire. So, I tried plugging it in via FireWire to my MBP, put the MBP in Target Disk Mode, put the CD in it, and held Option while booting the iBook. The iBook sees the CD on the MBP, I click on it to boot it, and it shows the Happy Mac (this is with the 10.1 CD). However, after about a minute, it shows a strange "broken folder" icon (a Mac OS 9 folder with a tear down the middle) on a grey background. It gets no further. If I use the 9.2.1 CD, it shows a Happy Mac briefly then switches to a floppy disk with a question mark. The 10.3 CD refuses to boot at all. One thing I forgot to mention is if I try and boot the iBook normally, it shows a Finder icon alternating to a ? in a blue Mac OS 9 folder.
G4 won't boot. No startup chime. Power button light goes off right after I power it on. Fans go on and soon switch to high / fast mode.
Tried everything imaginable -- removing all cards, RAM swapping, PMU reset, bought a new 3.6v PMU battery... everything on this forum (I think) except buying a new power supply which I'm trying to avoid.
I've had my iBook for about a year and a half now, haven't had any trouble with it until now. For some reason it won't start up. It's plugged in and the green light is on but it's just not booting up. why my iBook isn't working all of the sudden?
my ibook 800mhz g3 isn't booting up. I just turned it on one day & it showed the apple logo as usual, it went to the Starting up screen, and then it just disappears and i'm left with a blue screen, and the mouse sometimes appears for about 10 seconds and then it goes away. i've tried formatting, installing an earlier operating system, using a boot cd, booting from an external hard drive, everything.
I'm sure I've heard somewhere that it's possible to turn Macs on via ethernet, I've looked around on google and the forums here but haven't found a thing saying how to do it. Is it possible merely I imagined this?
I want to boot a G5 iMac, connected via ethernet through an AirPort Extreme, (802.11n 100Gb model).
I'm having a problem with my Powerbook G4. I kind of screwed up my drivers because I was an idiot and tried to get some Intel drivers to work on the computer through some cheat thing and now my computer won't boot up. I have an install disk but when I try to reinstall it keeps saying that I need Mac OSX Install Disk 2. I never had to use disk 2 before and I never had one to begin with.
I know very very little about computer parts and things like that, but I hope to have provided enough information. When I boot up, both plugged into the power cord, and on battery, the powerbook will reach a white screen with an apple logo in the center. There also is a rotating disk below the apple logo. It will then shortly power down. I made a visit to the genius bar, and they told me something was wrong. I was like DUH!!! They said for $320 it would all be fixed, but I was hoping to be able to find out what was going wrong with it. Sadly I don't have the start-up disk that came with the laptop .
I opened up my G5, to install more RAM, and saw that one of the hard drives was unplugged (I just got it used), and so I connected that, blew some compressed air into it, installed the RAM and closed 'er up. Then I tried to power on and it didn't work (No Chimes, just fans spinning, no video, not even the start up chime). So, I disconnected the hard drive, took out the RAM I put in, and closed it, and it still doesn't boot. Same thing. My keyboard is wireless, but the wireless dongle thing doesn't get any power when it is "powered on". The fans are spinning all the time. (Except when it's powered off, obviously)
Have searched MacRumours and am unable to find a solution to my problem, so here goes: I've recently bought a "faulty" PowerMac G4, which would not boot, however all the parts inside were sold as working.
When I try to boot the G4 the light on the front flashes and the fans begin to spin but there is no characteristic Apple "bong" and nothing appears on the screen.
I know the screen's working because I use the same one with one of my Windows PC's. I've tried pressing the CUDA button and reseating the PRAM battery but to no avail. Does anyone know what my next step should be?
