Mac Mini :: Slow Bootup With Blue Screen - Able To Enter Password In Safe Mode

Nov 28, 2009

I've been using my Intel Mac-Mini without a hitch for three years now. Previously it had been plugged into a Samsung 32" LCD TV, but I've just swapped it over for a 1080p Panasonic 37".

Now when I turn on the mac it takes a long time to boot up and then eventually settles on a blue screen. The mouse pointer is visible but nothing else. I've tried using a dvi to vga adaptor and an HDMI to vga cable and the same thing happens.I tried a 15" Samsung monitor and the same thing happens.

If I boot in 'safe' mode it allows me to type in my password but when I try to log in it fades to blue and then returns to the log in page.

OS X :: Freeze On Blue Screen / Can Only Start Up In Safe Mode

Sep 21, 2008

I woke up this morning and my iMac G5 (w/ Leopard) was frozen. I restarted it manually, but it would freeze on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM - any other ideas?

What can I do in Safe Mode that might fix my comp? I haven't recently installed any applications, and I have all "open at login" items turned off.

IMac :: Hang Up On Blue Screen - Only Boots In Safe Mode

Jun 18, 2009

Tried everything from archive and install (wouldn't read disk2 until the 9th try and ended up with 9 system folders). Then tried an Erase and Install. Still it refuses to boot. Get's hung up at the blue screen. Will only boot in safe mode. Now for the last few days even the startup chime is missing. Tried PRAM and NVRAM resets. no help. Won't boot from DiskWarrior boot disk either. Just hangs

Software :: Frozen On Blue Screen / Only Safe Mode Start Up

Dec 8, 2008

My iMac G5 froze. I restarted it manually, but it kept freezing on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM.
Finally I resorted to an Archive & Install. That didn't work so I did a clean install but that didn't help either. After having done everything under the sun to it to get it to work, it will still only start up in safe mode. I even tried starting up off each of my two external fire wire drives with no luck (it froze on the fire wire screen with both drives - a Maxtor and a Western Digital). I am thinking that something on the mother board has died so that normal booting is prevented but safe mode booting is allowed.

Software :: IMac G5 Stopped At Blue Screen (Safe Mode)

Sep 6, 2009

When I turned my iMac on this morning (iMac G5 PPC 10.5.8) it went through all of the "normal" steps (gong, grey screen, apple logo, progress wheel, blue screen) and stopped at the blue screen. Thinking it was just a fluke, I shut the machine down and restarted, only to have it stop at the blue screen again. After disconnecting everything going into the iMac except the keyboard and mouse, I attempted to boot into safe mode but it stopped at the blue screen again.

Next, I flashed the PRAM (big gong, single quieter gong) and afterward it came to the blue screen. I reattached my external drive and selected to boot from a 2-day old backup. Using the backup I was able to log into both my regular account and my "test" account (without login items). I still cannot login (except to my external drive backup).

MacBook :: Boot In Safe Mode - System Stuck At Blue Screen

Nov 30, 2010

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?

Power Mac :: G5 Stuck At Light Blue Screen - Will Not Even Boot In Safe Mode

Mar 22, 2012

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.

Intel Mac :: Possible To Password Protect Safe Mode?

Jun 6, 2012

Is it possible to place a password when booting into safe mode on my Mac. Let me explain a little more. I know that the accounts are all their and you can place passwords on the user accounts, but here is my problem. I use k9 web filtering and when you boot up in safe mode it does not work and you have unfiltered access to the internet. Is it possible to only allow the system admin to boot into safe mode with a password so no one else would have access? Its a work around the filter I am trying to block.

OS X :: Safe Mode And Open Firmware Password Enabled

Nov 11, 2010

I have the Open Firmware Password enabled, which prevents my machine from booting into Safe Mode when I hold the shift key at startup (as expected). As a result, if I want to use Safe Mode I have to boot up from my install DVD, disable the password and then reboot. Very time consuming! I just read about a way to boot into Safe Mode:

(at [URL="http://support.apple.com/kb/ht1455"]Apple Support[/URL)]
by entering the following terminal command: sudo nvram boot-args="-x"

I'm a little hesitant to test it out in case I run into some sort of Open Firmware/Safe Mode conflict.

OS X Mavericks :: Time Machine Backup Slow Even After Restarting In Safe Mode

Jul 1, 2014

I have an extremely slow Time Machine backup. I've gone through the motions and tried to resolve the issue by doing the suggested restart in Safe Mode.I don't use Norton Symantec but I didn't the Norton Remove script through the Console already. I don't run any anti-virus software. This started when I was backing up to at Time Capsule. I backed up to the TC for years before this started. I then moved to backing up (started fresh) to a external HD connected via USB. I have a 2010 Mac Mini with OS X 10.9 (Latest Version)

MacBook Pro :: When Restart Machine, Bootup Is Really Slow And Then Get A Weird Screen Glitch?

Apr 7, 2007

I have a 1.83 MBP, with 1.5 gigs of RAM (stock 512 + additional crucial 1gb) 80 gig HD. Pretty standard.My issue is that once in a while when I restart my machine, bootup is really slow and then I get a weird screen glitch. Often I won't get a full re-boot but will get a half appearing dock and no desktop icons. Sometimes it will have lots of grainy lines across it. Sometimes I will get the beach ball for extended times and it will just freeze there. Basically I keep restarting it, and eventually it goes away and boots up normal.

The thing is I can't really replicate the problem. It just happens at random. Sometimes it happens after I have a system crash, and I need to restart, and sometimes it happens just after a system update restart.Like I said, it doesn't happen that often, but when it does it kind of freaks me out. I've had the logic board replaced in the past to eliminate the "whinning" (which, thankfully is now gone) and I wonder if this is another logic board problem. Other than that the computer has been great. And upon the complementary Applecare expiring pretty soon, I wonder if I should take it in for a repair or just not worry about it. It's kind of hard to take it in if I can't really show them the problem.

OS X :: Won't Boot In Safe Mood / Only Boots To A Blue Screen

Aug 24, 2010

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.

OS X V10.7 Lion :: Installer Stay Stuck On Password Enter Screen When Installing Apps?

Apr 11, 2012

When installing apps through Installer (from .dmg disk images and .pkg packages), everything works smoothly until it asks me for a password. When I enter it, Installer goes back to the screen before it asked me for the password. When I click next, it asks me for my password, and the cycle repeats. I tried removing my password to no avail. I can install .pkg files from the sudo installer -pkg command. I dont know how to do this for installers that are in app form.

MacBook Pro :: Starts With Black Screen Only - Same When Boot In Safe Mode

Dec 6, 2014

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.

Intel Mac :: Gray Screen On Start Up - Backup Files Using Safe Mode?

Mar 8, 2012

I'm getting the gray screen when I startup. I tried using the install disc to repair the utility, but it said it cannot be repaired. I had to use a plug-in mouse instead of my normal wireless mouse to get the startup disc out on a restart. I want to now startup in safe mode, but holding down shift during startup with my wireless keyboard doesn't work. Do I need to have a plug-in type keyboard for this function to work? Can you backup files using safemode?

OS X V10.7 Lion :: Macbook Pro Freezes At Logo Screen, No Safe Nor Recovery Mode?

Jun 5, 2012

my macbook pro today started to freeze at logo scrren. I tried to start it up in both safe and recovery modes but it doesn't work either. I got the system to start in safe mode only once and the scrren looked like in the attached image.When I tried printing the screen instead of taking a photo with my mobile, the image appeared to be normal (without those noisy rectangles), but it wasnt. Then itried restarting but it's been impossible. As i said i tried booting on safe and recovery modes but the circle below the apple logo appèars and then it freezes again. I read about aproblem with the graphic card similar to mine in earlier models, I don`t know if it is the same problem.
