My mac is stuck on the white startup screen!

So, my sister was fooling around on my laptop, and somehow managed to change the color display. After that, system preferences became unresponsive, so I forced quit. After that, it would be unresponsive every time I opened it. My other apps like Safari and Chrome would shut down within a few seconds of opening them. So, I tried restarting. When I tried to turn it back on, it got stuck on the white startup screen with the apple logo in the center. It's still stuck that way! It's a school laptop, and winter break ends soon. I need this fixed ASAP, thanks!

How to unblock disk on MacBook

by

Seems you are in for a OS X reinstall. You shouldn't loose any data. Could also be the disk is starting to fail. That can happen after 5 years or after 2 weeks. Start with CMD+R into recovery and choose "Reinstall MacOS X". I would also try first Disk Utility from the same recovery menu to make sure the drive is ok.

by

Tried all the solutions save Disk Selection as only have one HDD, will not start in safe mode, did the Disk Utility check with no flags, finally OS X reinstall which took a couple of hours and now it is at the same place i started with the white start up screen, apple logo and progress bar stall at the very end.

Am seriously frustrated and do not know what to try next? Is there any other process to try, I did not turn off the power after the OS X reinstall

Reset NVRAM

Sometimes you need to restore the NVRAM to get your computer functioning again, reset the NVRAM by powering down the MacBook; restart and immediately hold down the "Command-Option-P-R" keys simultaneously. When you hear the start-up chime a second time, release the keys.

Startup Disk Selection

After resetting the NVRAM, you may need to select the startup disk. This issue usually affects computers with more than one hard drive. Start the computer as normal and hold down the "Option" key as the computer starts. When the Startup Manager displays, use the left or right arrow keys to cycle between hard drive options. Select the main hard drive, usually called Macintosh HD, and press the "Return" key. Wait for your computer to boot into the operating system.

Safe Mode

Starting in Safe Mode also includes an automatic disk check to verify and repair any issues with the operating system software. If you boot into Safe Mode successfully, you can then shut down your computer and attempt to boot normally. To start in Safe Mode, shut down your computer and press the power button to restart; after you hear the start-up chime, press and hold the "Shift" key. Release the Shift key when you see the gray Apple logo.

Disk Utility

Use Disk Utility to check the status of your hard disk and make sure that you don't have a failing hard drive. Shut down your computer; restart and then hold down the "Command-R" keys until you see the OS X Recovery utility screen. Select the "Disk Utility" option and select the "First Aid" tab. Select your hard drive from the sidebar and then click "Repair" to diagnose and repair the disk. If you have a failing hard drive, a notice displays telling you to back up your system and reformat the hard drive.

Reinstall Mac OS

Reinstalling Mac OS X fixes any corrupt system files and repairs the operating system without deleting your files, applications and other data. Restart and hold down the "Command-R" keys. After you access the OS X Recovery utility, you may need to select a Wi-Fi network so that your Mac can download the latest installation files. Select the "Reinstall OS X" option, click "Continue" and then follow the onscreen prompts to complete the reinstallation of your operating system.

Hope this can help you!

Thanks SydneyBush for the Step by Step Troubleshooting !

My Mac Pro crashed last night while working. I went step by step and first tried NVRAM Reset a couple of times. Later I tried startup disk selection. I did get the option to select the only once. but nothing happened after. So i moved on to Safemode. Even though it didnt boot completely in Safemode, it shutdown properly after displaying white screen for a while. After this, i moved to disk utility. It worked like breeze. The utility showed all the drives. i did the verify and repair disk. there were no problems with the harddisk. however it did reveal that there was hardly any space available on my harddisk (20 MB out of 1 TB). I restarted the Mac. it booted properly and cleared all the unwanted files and increased the available space to 150 GB. Remember do all this with Main Power plugged in. A few of the attempts were futile when we tried all this on battery power.

Cheers

Thanks for the info! My issue happened after a system update, it was asking for a restart and I let it do it, after that it wouldn't start at all. It would lock in the logo screen with the progress bar at about 50%.

I tried all steps above but only the "Reinstall Mac OS" worked for me. And it worked as expected, it download the OS, reinstalled, and everything is back normal, no changes to settings or software.

Thanks for your help!

i think you need to do some clean up and try removing some unwanted software, remove all unwanted start up programs and clean the disk and get the latest mac O.S and for more visit https://discussions.apple.com/thread/507... and make sure you restart the computer after update and settings

I'm experiencing the same issue and tried to resolve as Sydneybush suggested. But I shut down the MacBook after checking the status in disk utility. It was unresponsive (spin wheel was taking too long) and after rebooting using all methods mentioned above the load screen appears with a blinking "?" Folder. Honestly I'm at a loss now and need some help reinstalling OS X.

Add a comment

None of the options have helped for me. I am able to start up the computer, I hear the chime and it is a white screen. No logo, processing circle, nothing. The only one of the suggested restarts that had some type of response was the NVRAM, the screen would go black and chime over and over again until I released the "Command+Option+P+R".

I am unable to identify if the disck is full, or anything. HELP!

Is that a hint :-} You need to clear out some files to make room.

You should leave about 1/4 of the drive free for a HD, SSD's also need free space but unlike HD's smaller SSD's need more space 1/3 free otherwise you'll have uneven wear which will wear out the SSD prematurely.

I have done ALL the possible things regarding this white screen of death - to no avail. Every single time I re-start it gets stuck at half way loading and then eventually just shuts itself down. Looks like the 2K $ plus I paid for this Mac in the end was not worth it - my last HP laptop lasted about two years longer...

I'm having a similar problem. Booting gets stuck. I'm sure it's stuck, - went to work, came home 9 hours later, it was still stuck.

Things I have tried with no luck:

1. Reset the PRAM

2. Used recovery mode to check the disk - it's fine: has 25% free, has no other issues.

3. Used safe mode to boot - it gets stuck too!

4. Booted in verbose mode - all the initial messages seem ok - then I see the white screen, logo, progress bar (not verbose anymore) and it get's stuck.

5. Users recovery mode to reinstall the OS. Seemed to work, then reboots, gets stuck.

From recovery mode, I'd like to inspect the logs - is this even possible? looks like Console.app is not located anywhere obvious.

Super frustrated...any help or advice would be greatly appreciated.

TIL2 - MacOS Sierra install from Recovery seems broken. I downloaded a recovery image to a USB disk, then booted from it. Now I can install El Capitan, which seems to work. I can boot my Mac now!

From el Cap, I can install High Sierra. All good now.

1. Reboot into Safe Mode

2. Reset NVRAM

3. Reset SMC

4. Reboot and Repair Disk

5. Boot with Verbose Mode

6. Reinstall Mac OS

Yesterday i did an update (have high sierra, update was probably a small one) and after a while When Mac was avout to turn on after restart i got the circle with slender line.

Tried every step until restart Mac, which now says it cannot finish installation.

Mac worked perfectly before this smaller update and now seems to be totally unusable. Any answers? Can I undo this last update?
