Why is my Mac stuck on the white startup screen?
My Mac is stuck on the white startup screen! I’ve tried turning it off and on multiple times, but it just won’t get past the white screen. This issue started happening suddenly, and I’m unsure what caused it. There are no error messages or unusual sounds coming from the machine, but it just remains frozen on the white screen. This is quite frustrating as I can’t access any of my files or programs. I’ve also tried disconnecting all peripheral devices, but nothing seems to work. It’s essential for me to get my Mac back up and running, as I rely on it for both work and personal tasks.

One way to address the white startup screen involves resetting the System Management Controller (SMC). For most desktops, unplug the power source, wait for 15 seconds, reconnect, and boot up. For laptops, the process varies slightly, with specific key combinations to press. Another helpful step is to boot from a bootable USB containing a clean copy of macOS to see if it’s a software-related issue or something deeper requiring professional attention.
If your Mac won’t get past the white screen, begin by attempting a PRAM/NVRAM reset. Restart and quickly hold down the Option + Command + P + R keys simultaneously. This resets certain settings stored in memory. If this doesn’t work, start in Recovery Mode by holding down Command + R on startup and use Disk Utility to repair the disk. These steps often address common issues causing startup problems.
To troubleshoot, consider disconnecting all external devices, including keyboards, mice, and external drives. Restart the Mac with only the power cord connected. Hardware peripherals can sometimes cause startup conflicts, and isolating the device might help identify the culprit. Additionally, try resetting the NVRAM by holding down Option, Command, P, and R keys during startup for about 20 seconds.
