MBP internal screen doesn't work. External works but doesn't boot.

I'm really out of solutions because I'm not sure a lot of people had my problem. Whenever I try to boot my MacBook Pro in normal mode the internal screen is black and it doesn't work. If I connect an external display I see the login screen but whenever I enter my password it loads halfway then it shuts down and restarts. Once the password is entered the internal display lits up with a black background. Unfortunately I cannot boot it in normal mode even if the internal display seems to work.

Whn I try to put it in safe mode it I can log in but the same thing happens. The internal display is lit with a black background while the external display shows the normal background of the computer. So the only difference is that when I'm in in safe mode I can log in the computer while in normal mode I cannot.

You’ll need to setup an external bootable drive to isolate out if you have a hardware or software issue. Do you have a boot drive setup? If not you’ll need to find another Mac to set it up. What is you macOS release?

I do have another MB at my friend's house. I'm on the latest build. Cătălina? Not sure what subversion though. Do I need to have the same version set up via the bootable drive? Will it erase all my files too? Also is it possible to set it up from Windows?

da

The reason for asking was two fold making sure You didn't panic!!! ;-}

As Apple altered macOS with a newer file system (was HFS+ and now APFS). Using an older macOS like Sierra won't let you access the newer APFS file system so you won't see the files on your drive (they are not damaged just not accessible). It would be best using Mojave or Catalina so you don't panic!! ;-}

To be clear: Booting up on another drive with macOS won't effect your internal drive in any way.

But! You don't want MS Windows as that will mess you up! Just like a car which uses diesel you don't want to fill the tank with gasoline! As that will damage your car!

OK, so the second reason I ask was so I could aim you to how to create a bootable OS installer following this guide: How to make your own bootable macOS 10.15 Catalina USB install drive and how to use your startup keys to boot up under it by pressing the Option (⌥) key

Reference: Mac startup key combinations

Let us know how it goes - Good luck!

And again DON'T PANIC!!

Is the version I'm installing important? For e.g. my friend has a MB air. Would it be a problem or it's the same file no matter what the version of the computer is.

The external boot drive can have anything on it that your system can support OS-X Yosemite (10.10.x) or newer. Just don't attempt to access your internal drive.

We only eat to see if you can boot up cleanly on the external. If you had the correct macOS on the external then we could use Disk Utility to check your drive. Which won't be possible with the older OS releases.

Apple does expire older OS's so trying to create a boot drive from the old installer can fail. Apple reissued updated installers from El Capitan and newer. Here's a bit more on what happened: If you've got an old macOS install image, it will probably stop working today

Once you know what your friends OS version is let me know so I can aim you to the updated OS installer you'll need.

com.paragon-software.filesystems.ntfs - Crashed!

Re-installing the OS won’t wipe out the current OS files just overlay them and only the Apple stuff not any third party files.

Starting up on a virgin disk with a clean OS install is always the best way to figure out whats happening. Which is why I was pushing you to it.

You’ll need to do a surgical approach to remove the offending files, even still that won’t get you out of the woods as you may have other files that need to be removed or you can still have a hardware level issue.

Removable of old paragon software

Since you have a second Mac we still have an out! Here we will use Target Disk Mode to check your system this time using your friends Mac drive as the boot drive (running TDM on it). Did your system boot up clearly off your friends Mac drive?

The next direction is to switch it around! This time running your system under TDM so you can off load your stuff from your friends Mac to an external drive! Once you get your stuff of the drive I would reformat your drive from your friends Mac. That will wipeout anything else that’s messing you up.

Here’s the details on TDM! Understanding the Applications for Target Disk Mode.

Wait I'm confused. So basically Paragon made my computer crash and screen not to work? Isn't that a little intense? What about the humidity in the air? Do you think it has something to do with it? Also I don't see the line where it says that paragon software crashed

da

All I'm telling you us the crash report points to the Paragon driver.

As for the humidity, that would point to a moisture issue internally. A heavily dust filled system can act as a sponge holding the moisture! So I would clean the dust buildup in the fans. logic board and case taking as must of the system apart as you get to give it a good cleaning and inspect for corrosion damage.

All right, so the same problem occurred again. Same thing as yesterday. Computer was working fine at work (no A/C). Come back home, open the computer up and the screen doesn't work and it says the following message on the external display : your computer restarted because of a problem. Once again, can't boot it up normally. Internal display doesn't work. I was able to see the message on the external display only. I'm so confused. The only theory I have is that while driving and the MBP in my backpack, it accumulated humidity therefore making it unusable getting home.

Here's the error report (https://pastebin.com/zMuaFnVF). It does look similar to the other one.

Just to add a little detail to when I say it doesn't boot up : My problem is that it boots (I can get to login screen) but once the credentials are entered, it doesn't load the desktop and restarts.

Top loaded kexts is still com.paragon-software.filesystems.ntfs
