Hello, AndréGabriel!
I perfectly understand your concern about the intermittent "Screen Glitch" you're experiencing on your new MacBook Pro M3 Max. It's truly frustrating, especially on such a new and powerful device.
First of all, it's important to clarify that no, a screen glitch like the one you describe is not normal behavior for a new MacBook Pro, nor for any Mac. Your device should function flawlessly.
Considering that the problem occurs intermittently and in different modes (including safe mode and during boot), this could indicate either a software or a hardware issue.
To try to isolate the cause and, hopefully, resolve the problem, I suggest some diagnostic steps you can try:
- Check for software updates: Make sure your macOS is fully updated. Go to System Settings > General > Software Update. An update might contain fixes for known bugs.
- Reset NVRAM/PRAM: This can resolve issues related to some system and video settings. For Macs with Apple Silicon (like your M3 Max), NVRAM is automatically reset on startup if needed. However, you can try shutting down your Mac and turning it on again, or restarting multiple times.
- Test with a new user profile: Create a new user on your Mac (in System Settings > Users & Groups). If the problem doesn't occur in this new profile, it might be a specific setting or login item in your main profile.
- Run Apple Diagnostics: This built-in tool can help identify potential hardware issues. For Macs with Apple Silicon:
- Shut down your Mac.
- Press and hold the power button until you see "Loading startup options."
- Press Command (⌘)-D on your keyboard.
- Follow the on-screen instructions.
What to do if the problem persists:
If the glitch continues after these steps, it is very likely a hardware issue. In this case, the most important recommendation is to contact Apple Support directly or schedule an appointment at an Apple Store or Authorized Apple Service Provider.
They have the necessary tools and expertise to perform a more in-depth and accurate diagnosis, identify the root cause of the problem, and arrange for any necessary repairs. Since your Mac is only 13 months old, it is essential that a certified technician evaluates the situation.
You can find contact and scheduling options on the official Apple support website: Official Apple Support.
I hope this guidance helps resolve the issue quickly and that you can enjoy your MacBook Pro to the fullest! If you have any more questions or need help with anything else, just let me know!
