My mac is stuck on the white startup screen

From time to time, you may experience one of the more frustrating Mac glitches — a white screen during boot. Usually this rare bug happens after updating macOS to a new version, but it can happen at any time. There is no Apple logo on this display, nor will you see a progress bar showing where you are in the Mac boot process.

Reboot into Safe Mode One time-honored trick to recover from a white screen is to boot into Safe Mode. This is very easy to do: simply hold down the shift key on your keyboard as soon as you hear the Mac startup chime.

Keep holding down the shift key until the boot progress indicator shows up. This progress bar indicates that Safe Mode is running a directory and disk check on your Mac; this is like running First Aid from the Disk Utility. Safe Mode is a way to troubleshoot some system problems that can keep your Mac from booting normally. Essentially, Safe Mode disables some macOS features, clears some caches, and prevents some third party kernel extensions from loading, all of which reduce the amount of work the Mac has to perform to get to the login screen. If you can boot a Mac successfully in Safe Mode, you either try to boot the Mac again to see if the next try is successful — perhaps just clearing some caches was what the doctor ordered.

How can you make sure that your Mac booted into Safe Mode? If you know what apps were recently updated, try removing them from the list of login items and then reboot normally to see if the problem is fixed. To remove an item, just highlight it by clicking on the item name, then click the minus sign — button below the list.

After removing a login item from the list and verifying that the system boots normally afterwards, you may wish to contact the developer with a bug report, or try removing and re-installing that app. NVRAM stores information in between boots of your Mac, things like the startup disk, video and display information, volume for the system startup chime and speaker, time zone information, default system fonts, and more. When resetting NVRAM, this data is all wiped from the Mac so you may need to readjust things like your screen resolution, mouse or trackpad tracking speeds, etc….

The Mac chimes once to signify that it has begun booting, then a second time to signify that the NVRAM has been reset. After this point, let up on the keys and let the Mac boot as usual. Resetting the SMC is another tool in your toolbox of white screen solutions. When your Mac is shut down, disconnect all the peripherals including printers, scanners, USB devices except the mouse and keyboard.

SMC—system management controller, simply put, controls your Mac's system. To reset it may also solve white screen problem on your MacBook or iMac. Press the left-side Shift, Control, Option keys, and the power button on your keyboard all at the same time. Then release all of them at the same time.

Settings include display resolution, startup-disk selection, time zone, and recent kernel panic information. If you use iMac Pro, release the keys after the Apple logo appears and disappears for the second time. If the white screen on mac problem relates to a damaged startup disk, try repairing it by Disk Utility in Recovery Mode. Verbose Mode is a bit distant from users.
