MacBook Pro 16” (2019, Intel) – No Menu Bar, No Apps Launching, Safe Mode Same, Disk Utility First Aid Fails

Hi everyone,

I’m dealing with a serious issue on my 2019 MacBook Pro 16" (Intel, Touch Bar, latest macOS).

Symptoms:

- After login: Dock appears

- No menu bar

- No desktop (no files, no right-click)

- Finder does not properly start

- Finder Restart does not do anything

- No apps launch (Terminal won’t open either)

- Same behavior in Safe Mode

- NVRAM reset did nothing

- SMC reset did nothing

- Deleting Dock / Finder plist files did nothing

Additional details:

- SSD is 1TB, about 85% full (so not completely full)

- Tried forcing new user setup via deleting `.AppleSetupDone`, but system still boots directly into my existing user account

- Disk Utility → “First Aid” fails on “Macintosh HD”

- Problem appeared suddenly (no known crash during update, no intentional system changes)

Important:

Safe Mode does NOT fix it. No menu bar even there.

At this point I suspect:

- APFS container corruption

- System volume corruption

- WindowServer unable to start due to filesystem issue

Before I consider erasing the disk, I’d like to understand:

- Is there a way to repair APFS beyond First Aid?

- Could reinstalling macOS over it fix this if First Aid fails?

- Is this likely SSD hardware failure on a 2019 Intel MBP?

No recent third-party system modifications that I can recall.

Any guidance would be really appreciated.
