Why is my Mac stuck on the Apple logo then blue screen?
I’m having a frustrating issue with my Mac where it boots up and shows the white Apple logo, but then the screen turns blue and nothing else happens. I’ve tried waiting for a while, thinking it might work itself out, but the blue screen just stays there. This seems to happen every time I restart my computer, and I’m not sure what’s causing it. Could it be related to a recent update or software installation? I’m worried that my files and data might be at risk. Has anyone experienced this problem or knows what might be triggering it? It’s really hindering my ability to use my Mac for my daily tasks. Any insights into why my Mac is showing the Apple logo and then a blue screen would be helpful.

When all else fails, reinstalling the operating system might be the best bet. Enter macOS Recovery by restarting your Mac and holding Command-R. Select ‘Reinstall macOS’ and follow the prompts. This won’t delete your files and fixed my boot issue. Always backup your data just to be safe before doing this.

This frustrating issue once affected me and the solution turned out to be hardware-related. Took my Mac to the Apple Store, where they ran a diagnostic and found the hard drive was failing. They replaced it, and my Mac’s startup returned to normal. If other fixes don’t work, getting a hardware check might be a wise move.

During my own struggle with the blue screen, booting into Verbose Mode helped diagnose the problem. Restart your Mac and hold Command-V right away. You’ll see code lines and processes, which can help identify any conflicting software. Once I found the culprit, removing it in Safe Mode resolved everything.

Had the same blue screen problem with my Mac recently. A good trick that worked for me was resetting the NVRAM. Shut down your Mac, then turn it back on and immediately press and hold Option, Command, P, and R keys for about 20 seconds. This reset fixed my startup issues and my Mac returned to normal functioning. So worth trying!

In my case, updating the macOS actually solved the issue. It’s easier than it sounds. Just connect your Mac to the internet and start it in macOS Recovery by holding Command-R during startup. Choose ‘Reinstall macOS’ and follow the instructions. This method doesn’t erase your files, but it’s wise to backup important data first.

Believe it or not, simply disconnecting all external devices worked for me. External hard drives and USB devices can sometimes cause startup issues. Unplug everything, restart your Mac, and see if it boots up fine. You can reconnect your devices one by one later to find out which one might be causing the issue.

I encountered this exact issue a few months ago. What really helped was booting into Safe Mode. To do that, restart your Mac and hold the Shift key right after turning it on. Once you’re in Safe Mode, it disables unnecessary processes, allowing you to uninstall any recent software that might be causing the problem. This actually worked well for me when a newly installed app turned out to be the culprit.
