OS X :: Login Screen Show In Red - Safe Boot
Aug 15, 2010
Today, while turning on my iMac, a strange gray progress bar appeared in the 'Apple' start screen. I assume I felt some fear. Then, the login screen shows in red: 'Safe Boot'. Later, the menu bar appeared to be brighter than ever. Thanks to google, I found that safe boot is a mode which you can access by holding shift during startup. Probably I pressed shift accidentally, even though I do not remember. The question is: now, that I restarted my mac and it's back to the normal, will this 'Safe Boot' bring me any consequences? How to proceed?

I just go a new Macbook Pro 13' from my school (my school made it mandatory to get a mac this year) and I was installing some of my applications. Then I got the "You need to restart your computer" message. I restarted, and all i got was a blue screen with my pointer. Then after a while it says the same restart message. Also I have tried booting from the Snow Leopard Disk, but I get the same message before the actual SL installer comes up. I have been able to get the Macbook to boot in safe mode and I repaired permissions and the disk, however that does not seem to help. I have also reset the PRAM and that did nothing. I am running out of ideas... how can I fix this? I am using 10.6.4.

My MacBook is making the startup sound but goes straight to a black/dark grey screen. In other words you can see the screen switching on but it's blank. It's in charge mode, has no other external peripherals attached and it's updated to most recent OSX Yosemite.
I only purchased it in May of this year (refurbished). I have tried booting in to safe mode but again the screen remains the same. Â

I tried fsck -f fsck -y multiple times, booting in safe mode, zaping the pram and all that stuff, nothing as worked. I don't really care about how to fix it but I care more about, Is there any possible way I can get files off of the macbook even though it wont boot. Like is there a way for another computer (windows or mac) to pick it up so I can transfer files? What accessories will I need?

I have a 2.0 GHz early 2005 Power Mac G5 (7,3) that won't get past the light blue screen at start-up. I've tried everything - reset the PRAM, Apple Hardware Check (on overnight loops, everything came back OK), fsck (all OK), repaired my HD and permissions on it, and then erased the drive using Target Disk Mode and another Mac, and attempted to reinstall OSX from the install disk that came with it (with OSX Tiger). I've tried switching out the RAM with no luck.
The only thing I haven't tried is a new video card (the installed one is an ATI Radeon 9600). Here's what it does: powers on with the usual chime, then moves on to the white Apple screen, the wheel spins, then it moves on to a darker blue screen, then it finally moves on to a lighter blue screen with an arrow, and it just stays there. It will boot into safe mode (pressing shift), but I can't even upgrade to Leopard in safe mode, much less figure out what's wrong.

I Have a 15" MacBook Pro with Retina display. I tried to move files off the hard drive when I got a message warning me that the drive was almost full. I shut down, connected an external hard drive to move some files, but on reboot, the screen went blank (white) after typing in my login details.

This is the first time I've encountered this. Upon cold booting the machine it went directly to the legacy Mac OS X Server login screen from before the upgrade to Mavericks. It would not let me login with current credentials. I had no choice but to hard power off. It returned to normal operation on restart.
It could be a possible bug.

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. Â
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".Â
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.Â

I have a duplicate item, namely Expander Daemon, in Sys Prefs > Accounts > Login Items. The first one heads a list of 7 items in total. It says its Kind is Unknown. The second ED is at the end of the list and its Kind states Application. Is it safe to remove the first ED?

My MBP (2012 or 2013 not sure which!) is having an issue. When I try to login, my password is accepted and then a progress bar appears. After a quarter load, my mac turns off. Unfortunately safe mode (holding shift) does not work. I have tried smc and pvram resets and repairing through disk utility. None of this has worked... Â
I'm running yosemite. The last thing I did before logging off is installing divx web player.

After numerous attempts at booting into safe mode while holding shift on start-up, I tried entering sudo nvram boot-args="-x" in terminal to force it manually. Turns out my mac didn't like it that much.
Now whenever it starts up, it hangs on the gray screen for a bit and turns off immediately, never booting.

I have a Imac PPC with a 2Ghz processor and 1GB of Ram. I am running leopard 10.5.8. Recently i woke the PC from sleep mode to find a blue screen with only the cursor working. Using the internet, I determined how to get the PC booted in safe mode. I have used all the disk utilities at my disposal along with onyx and cocktail to try and fix what I believe is a startup problem. I hae booted the PC in single user mode and tried the fskc codes, which i believe is just the same as the disk utility. Based on my computer all permissions are correct and there is nothing wrong with the HD. The PC still will not boot normally. I have even done an archive and re-install of Leopard.Â

Hi! Im new to the forums but i really need help with something and i was hoping someone here could help me out. So I just installed Tech Tool Deluxe onto my macbook and then shut it down later. I went back to use it again and when i turned it on a login screen appeared asking me to put in my password. I did that and the screen turned blue (looking like it was loading) and then went back to the login screen. Every time i put in my password it just takes me back to the login screen. I have had my mac for a while and i dont want my hardrive to get wiped out so what do i do? Thank you for looking

I have unchecked every app in the Login Items menu in System Pref. Even deleted them out of the menu. Safari, iTunes, Mail, and a Finder folder show up automatically when I restart or login to my iMac. I have read some posts on this and I'm also aware that you can right click on the app in the dock and make sure it is unchecked to open at login. This problem seems to have started after I removed programs I did not want to start up in the Login Item menu in System Preferences.

I have a 08 MacBook pro (not unibody) and it is now not booting up. I recently installed a Hitachi 500gb hard drive on the computer and restored through time machine and it worked fine for about 2 weeks and now wont boot and I'm wondering if its probably the hard drive. When I click power the light on the front of the computer will come on and it will sound like it is about to boot then a clicking noise seems to come from the computer and it instantly shuts off. I have gotten it to turn on a couple times since it happened by slamming the comp on the bed then for some reason it will work but as soon as I shut it, it wont turnback on. Any ideas?
Oh and PS the screen never comes on and can't boot in safe mode.

When I restart my computer, not all of the users are shown in the Login Window. Only the Master account is shown. When I LOGOUT only then are all of the users shown. How do I get all of the users shown in the LOGIN window when the computer is restarted?

As of yesterday my Mac book pro will not start up. It will not go past the gray screen with the apple and spinning timer indicator. When I try and start up holding shift to enter safe mode it will not start up either. I have tried turning It on and off many times. I am not sure what to do or what the problem might be. Running OS 10.7.

MY MBP is giving me the "NOT" sign on start-up. This comes after initially displaying the Apple logo. This MBP had a new logic board installed by Apple just two weeks ago -- and I know I can take it back but I'd like to fix this myself. I put in a different hard drive after getting the MBP back. It has worked fine for several days. Don't know if these points are relevant, but:
1. First thing I noticed today is that neither of the USB ports would read a flash drive. The port would, however, work mouse and keyboard.
2. The initial non-boot episode took place when I had external hard drives daisy-chained in via Firewire. But, again, this had worked previously, as recent as this morning.This may be significant:
3. The last tasks performed on the MBP were -- for the first time -- to edit video in FCE, make DVD in iDVD, burn IMG file.
4.I have connect this MBP as a target FW drive to another MBP and run "disk verify" and "disk repair" in Disk Utility. It says the drive and permissions are okay.
5. I have booted to a copy of Disk Warrior (latest version, version 4, I believe) and rebuilt directories and files along with verify/repair permissions (everything DW will do). And when re-starting, it still won't boot.
6. When I boot off Snow Leopard DVD and run Disk Utility¦"verify disk" says "the volume appears to be ok¦.when I "repair disk" it reports "Volume repair complete." and "Updating boot partitions for the volume as required."
7. I'm able to boot in SAFE MODE, but when I try to restart in normal mode, it won't boot (so nothing was automatically fixed)What can I do in safe mode to address my problem?

My Mac started doing this a few weeks ago, where after login it all kind of collapses. Sometimes the desktop icons won't show up, or Hear (which runs on startup) will get stuck loading for a long time. Sometimes everything seems fine but no programs will launch, or the dock won't respond. So far I've done an Onyx cleanup run, a Disk Verify and Repair. Permissions Verify and Repair and even did the good old Command+R on startup and reinstalled Lion. It worked the first time and then it went back to its old antics. I'm afraid if its a corrupted file and even if I get a new Mac then when I restore from Time Machine it'll carry over.

We have an older model G5 Dual (no Intel Core) at the office that we tried to install CS3 on. I told them that first we would need to upgrade from 10.3.8 to 10.4.10, which they did, and then installed CS3. But they did it without running the disk utility repair permissions after the OS software installation, as I have routinely done with my Mac Mini at home, after the horror I experienced with the 10.4.9 upgrade. For a couple of days, the computer ran fine, but I noticed an increase in the fan spinning up yesterday afternoon, then quirky keyboard things -- like I'd select an item with point and click, and it would highlight everything else near it, I'd go to quit an application and it would ask if I wanted to quit all applications.
After backing up my current InDesign work files on a flash drive (but not the whole darn art folder), I rebooted and it came up in Safe Boot mode 6 times without holding any key down. Attempts to boot from disk have failed, even with holding down the "C" key. It's also not allowing us to type out full passwords at the log-in screen... you start typing and after you hit four digits, it clears, then only allows two digits. How we can:
1.) Force boot from disk, and,
2.) Hopefully fix with disk utility whatever wonkiness is occurring?

I own a MacBook, bought in 2008 with Leopard as an OS. It is the black model, if this helps. While I was browsing, Firefox started behaving strangely. It was taking forever to minimize windows and could not use the top right function to view all applications/windows open. I restarted the mac but when it booted up again it did not do it properly. For 10 minutes I had the greyish screen with the loading sign underneath the apple logo, then eventually it showed me the safe boot mode, asking for my password.
When I enetered it, it did not accept it (login window shakes at each attempt). I tried to log in from the CD, but again asked the password and did not accept the one I put in, even though I know it was the right one! Now I can't use the mac and can't access safe boot either. Would you know any workaround solution for this, like a way to reset the password? Have you got any clue on why the mac decided all in a sudden to boot up through the safe boot mode?

I am using a Late 2009 Mac Mini. This afternoon I did a software update, it was 4 programs that were updated. I didn't take a look at what was updated, which was a mistake, I know. But anyways, they installed fine, and the Mac rebooted, it got to just before the user select/login screen and hanged there. I was able to move the mouse around, but nothing else, and after a long period of time, I powered off my Mac, and now it is hanging at the Apple logo.
I tried booting into Safe Mode, and the grey progress bar would appear but and get half way through and then disappear. Next I tried inserting the Install DVD, hold down C while it was booting up but that wouldn't do anything.
