MacBook Pro :: Showing Apple Logo And Progress Bar On Startup Then Shutdown
Feb 19, 2012
I forgot to switch on the power socket at the wall so when I came back it had powered off. When I switched it back on it showed the last screen visible before sleep mode kicked in and then showed the apple logo with a progress bar underneath. The progress bar starts to move slowly but after about a minute starts again. It slowly starts to move again but stops after about two minutes and the macbook powers off.
I just bought a new 27" iMac and when I start it up I get a white progress bar under the apple logo. When it does come up, iTunes will not play and sometimes the computer will not recognize the magic mouse or my WiFi. Everything works fine after I re-start.
IT does this every time, but when I do command and r or other such keyboard commands, it goes I the recovery pahe with no problem. Whenever I tried erasing the iMac to reset it, it said the disk was locked.
Info: iMac, OS X Mountain Lion (10.8.5), April 2008 model
I shut the computer off like i normally do. It was fine and well. Went to turn it on, and saw a bar. Whats it for? Its been moving, but very slowly. It never does this. Is there malware or something causing it? I had a movie on the DVD slot, it that caused it. It wasn't spinning though.
My 24 inch iMac is not getting pass the apple logo. It acts like it's loading, but then the little progress spinner (not sure of the name) stops spinning after 2-3 minutes. It never wants to get pass that. I'm running the latest version of Lion.
Here's the specs: 3.06GHZ 4GB 500GB NVIDIA GeForce 8800 GS
So far I've tried using disc utility on my snow leopard disc....it doesn't load. I've tried to start in safe mode...it loads about half way and stops. Oddly enough windows xp works in bootcamp. It runs okay besides when I try to move windows. I'm guessing it's the graphics card. No idea really. Here is a video I made to show you what I mean: [URL]. I've also tried installing a new 1TB HD and it still won't boot from a disc for some reason. I tried install snow leopard through the internal superdrive and with an external superdrive. No dice.
Went to the Apple store, explained my problem and they brought out a new iMac for me. Did a retail swap instead of going through the Genuis Bar. I'm so happy =) =) Got a brand new iMac. This time, I disk Disk Check right away, and it says hard drive appears to be OK. No grey progress bar anymore! The problem was probably b/c the hard drive was defective. It had nothing to do with the unsafe shutdown, or pressing shift, etc...
I have a iMac 27'.. Purchased it 2 weeks ago.
I think I did an unsafe shutdown.. Or I pressed "shift" while booting, or something.. Idk and I also have WinXP installed on BootCamp. However for some reason now every time I startup my Mac, it loads with the grey Apple horizontal progress bar with a little loading animation on top. It's so annoying. This didn't happen after no firmware upgrade or anything. And I don't have any extra hard drives attached. Nothing. Everything is fine. Everything used to work. Even with BootCamp before. I think this happened after an unsafe shutdown or something. And also, my Mac has over 500GB free space still, so that's not an issue.
The progress bar at startup Takes 5-6 min extra to boot up. After it, the Mac OS X loads and everything is fine but that's not what my problem is. My problem is why should I be getting the stupid progress bar EVERYTHING I load my Mac?
I tried booting with installation disk, then going to Disk Utility but NOTHING. I click repair, and after 5 mins some error pops up saying backup your files when you can then reformat the disk.
Oh btw, Anytime I click Repair Disk it goes, then says: Updating boot support partitions for the volume as required. And after that it says: "Disk Utility stopped repairing "MY DISK NAME HERE". Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backend-up files.
Instead of showing white screen with an apple logo it became black screen instead but still can be log on to the desktop but ican't press alt to use bootcamp because the screen is all black TT?
Why does the apple logo briefly turn red when I switch on my Macbook Pro before reverting to grey and starting up normally? I hadn't noticed it doing this until recently.Â
My computer displays grey screen and apple logo for 10 minutes or more during start up and shut down. Sometimes it refuses to shut down. This issues started after installing OS lion. What do I do?
I recently noticed the Apple logo is magenta at start up, when it is centered on the screen, before it turns gray and moves up the screen to make room for login details. I cannot replicate the issue on restart but only see it when it starts up first thing in the morning. It literally flashes up for just a second or two then normalizes to gray.
Info: MacBook Pro (Retina, Mid 2012), OS X Mavericks (10.9.3)
I have a MacBook Pro from 2010 I believe with iOS Maverick installed. (MacKeeper is also on there, which I just found out is apparently malware)Â
So three days ago I was watching Netflix, the image froze, but the audio kept going. Figured my internet was slow, so I waited a little, nothing happened. pressed escape to leave the full screen mode, but nothing happened. None of the keys would do anything, not even the sound or brightness keys. So I did a force shut down by holding down the power button.Â
I waited a little, then decided to turn it back on. Start up sound played, white screen with grey apple logo and loading gear appeared together with a grey loading bar. I figured that this meant it had to repair something. But after about a minute or two it just went to a black screen/ shut down. I left it off for a day, tried it again, same thing. Next day I tried booting it up while holding the shift key to do the safe boot (I knew it wouldn't work since I already had the grey loading bar anyways), same thing happened.Â
I have a Powerbook G4 with me and it doesn't boot up. I am suspecting it is hard disk/ software error that is stopping it from booting up. Here is what I see when I try to power it up: White screen, Apple logo with the round circle with rainbow color. Do you guys think that is is a software error that is stopping it from booting up? The last thing I did was to install Windows Messenger for Mac! I am thinking of trying to do a re-install using the disc that comes with my Powerbook purchase but I am at a lost of what to do. Can anyone please share with me the steps that I need to take? I've got a 'new' hard disk already, please advise on how can I rebuild my Powerbook!
I'm noticing some weird behavior in my Mac Pro first gen.
Basically, when I start it up, the displays just stays black for some time, until the Desktop loads up and the computer is functional, but never displays the gray screen with the Apple logo. This just happened all of a sudden and stayed like this.
I know is not a big deal now, but I'd like to sell it in the near future and this could be problematic for that.
I just bought an iMac G5 off ebay and today I tried to use the Tiger install dvd because the previous owner had deleted software like textedit, etc.
Anyway, I put the disc in and clicked on Install Mac OS X, then clicking restart. once the iMac shuts down and begins to restart, as it is on the grey screen you can hear the disc being read, then as the background goes a different shade of grey and the Apple logo appears, a minute or so passes and then the iMac begins making a lot of noise. I went away for 10 minutes, came back and it was still doing the same thing.
So I'm basically looking for help because I really want to erase and reinstall everything.
I am fixing this 2007 iMac for free for an autistic child. Apparently, changing computers for someone that is autistic isn't ideal. I don't have the history with this iMac, just that it isn't working. They supposedly did have the hard drive replaced? It sounds like a dvd is inside it when it starts up, could be the installation dvd?Either way, I have not seen it before where the Apple logo refuses to show on the start up screen. It just stays gray. Â
1. I've tried zapping the PRAM. Didn't have any changes.Â
2. I tried starting up in safe mode, but getting passed the apple logo is required for thatÂ
3. I tried single user mode, but getting passed the apple logo is required for thatÂ
4. I tried holding the c key to start up off of the dvd, nothing happensÂ
5. I tried holding the mouse button (and cmd, opt, f, o) to manually eject the dvd during start-up.Â
I own an iBook G4. I could not get it to boot up, it would just go to a grey screen with the apple symbol and a timer/clock that looked like a gear.FYI: I may provide more information than necessary in the text below. I'm not sure what is and isn't relevant.
Following some advice I found in this forum I got out my old OS disks to boot from the disc instead of the hard drive. I intended to archive the old hard drive and install my latest OS (10.4.6 on the disc, 10.4.11 was the version I had been running on the machine, I believe). The machine told me it needed 4.5 Gb to install 10.4.6 Tiger, but I only had 4.0 Gb left on the hard drive. So instead, I archived and installed with the OS that came with the computer originally, 10.3.4.
I got things going, did the archive and install, and got to the log in screen. Unfortunately, I could not remember the password, so I booted up in single user mode, and entered the following to get into the machine:
1. mount -uw / 2. rm /var/db/.AppleSetupDone 3. shutdown -h now
This got me in with a new admin login, and I started up in 10.3.4. I soon noticed that I could still see all of the files that I put on the hard drive on my old operating system. I thought I shouldn't be able to see them, but since I could I decided to try to copy them to an external hard drive. When I did, I got an error message saying that there was a read/write error. I was not entirely surprised, but I decided it was time to turn back to the forums for help.
What I want to do is copy everything from my old hard drive onto an external hard drive, make room on the iBook hard drive to reinstall my latest operating system (10.4.6). Once I've done that I'd like to get the essential files back onto the iBook from the external hard drive and continue using my computer (even though it is a dinosaur).
I have a Rev A 12 inch Powerbook - 867 mHz, 640 RAM, 40 GB hard drive. The machine's always been reliable and has performed great over the years. I bought it the last week of July, 2003.
Yesterday, the Pbook was shut down, and I press the on button so it would boot up. Almost immediately, the hard drive makes a loud, whirring noise. The computer advances to the gray screen with the Apple logo, but it doesn't get past that point and the noise continues, as if it's a car engine that just won't start...
I'm going to take it to my local Apple Store in the morning, and hopefully the data, including my nearly 22 GB of music, can be saved. Any thoughts on how to get my computer working again? By the way, it's the original hard drive installed. Hopefully this is enough info to generate some ideas, I'm stumped.
I purchased a new late 2013 27 inch iMac 3.4Ghz i5. The only thing I did after pulling it out of the box was restore Time Machine from my previous iMac. On startup the machine boots as expected, but gets interrupted by the screen turning a dark blue, and the apple logo turning bright red, for about a second or so, then boots as normal, and opens Mavericks. I've spoken to Applecare - they suggested I re-install Mavericks, which I did. The problem is still there. I've done a hardware diagnostics test - no problems. Though I wonder if it could be a faulty graphics card? As far as I'm aware there are no other issues with the iMac. The machine is under warranty but would love to solve this if possible.
My early 2008 2.8GHz 8-core Mac Pro died last week. I tried all the usual stuff and ended up taking it to the local Apple store genius bar. They ran their diagnostics tool on it and did not find any problems so I had to leave it for a more thorough test. The Apple Store called a few days later and said it was either the main logic board and/or one or both CPU's. They -say- they replaced the main logic board and that did not fix it. They told me it would be ~$2800 USD plus labor to replace the the main logic board and both CPU's. So I took the machine over to another authorized Apple Service center for a second opinion. This other service center seemed confident they could determine which component(s) are defective. I am expecting a call from them on Tuesday of this week and hope to find out more then.
The symptoms are: When powering the machine I hear the startup sound and the display shows the apple logo. The machine boots for a little while (disk activity is heard) then the machine freezes for about 30 seconds then reboots or just freezes indefinitely. This happens with my 10.6.5 boot system, a second 10.6.x boot system on another internal drive as well as from the 10.6 SL DVD installer disc. Apple could not boot it off their network based systems either. Same symptoms on all startup disks tried so far...
So, I'd like to know where to go if I need to obtain parts and do the repair myself. I've built a number of PC's in the past and have no concerns about the undertaking. I just need to determine which parts I need. I'm not looking to "upgrade" the machine however if faster CPU's are available for a similar price I'd probably opt for the upgrade. At this point I'd be completely satisfied replacing the defective components with the same stuff that's in the machine now. Any pointers/links/tips/etc. would be most appreciated.
Today when I turned on my MacBook Pro (Mid 2010 model) , the apple logo appeared as normal, but then the spinning gear and a progress bar appeared under it. Now everytime in turn my computer on, this progress bar will appear, get to about the 2/3 mark and then the computer will abruptly turn off. I have read articles about this saying that I have to format my hard drive. I want to know if there is a way to fix this problem with out having to format my hard drive.
I upgraded to Snow Leopard and a few days later when i went to shutdown my mac pro after i woke it up, i got the blue screen and progress wheel just spinning. After calls with Apple, running both long and short hardware tests, 3 snow leopard discs, a clean install, 2 upgrades, the tech gave up. The clean install was a bare bones install with no applications installed. I would now have to take it into a repair shop and pay for software tests. This is a one year old mac pro with apple care. I used Time Machine to restore to leopard, and all is ok. Has anyone heard of this problem? I'm quit happy to stick with Leopard, but am upset that an apple software problem has to be fixed and paid for by me. I assume if it was a hardware problem it would show up in Leopard.
After restarting my MacBook pro for updates, I clicked on my user icon which read 'update needed'. After entering my password it began to install the updates, but the progress bar just stopped halfway through, and 2 hours later it hadn't moved. I then switched off my mac and tried again and again but the same thing keeps happening.
