Seagate NTFS drive no longer mounts on Mac Mini

Ok...so here's the deal...here's my solution for anyone who's had issues with the Paragon NTFS for Mac driver from Seagate (or otherwise):

QUICK NOTE: This worked for me. I can't say it will work for you.

If you install the Paragon NTFS for Mac driver and get a Security alert that tells you to "allow" it, that's probably at your peril if you're running High Sierra. If you don't, I think you're ok. If you're not, then continue. If you do and then restart, you may end up with a Mac that will take 20 to 30 minutes to boot up and then top out at 100% progress on the startup bar -- and then, nothing. You'll sit there until the end of time.

If this happens, do the following:

1) Boot your Mac into Recovery Mode (just hold down Option after the chime and select the "Recovery" volume that pops up).

2) Run "Terminal".

3) Type the following into the Terminal when you get there (if you see quotes, include the quotes):

• cd "/Volumes/(name of your driver here)/var/db/caches/opendirectory" (NOTE: if your hard driver includes a space in the name -- eg: "Macintosh HD" -- you have to space it like this: cd "/Volumes/Macintosh\ HD/var/db/caches/opendirectory")
• mv mbr_cache mbr_cache.old

4) Restart the Mac. This SHOULD boot you all the way through to your login screen -- AND your Paragon drivers should mount your drive.

If it doesn't work for you, you're probably gonna need to back up your Mac, flatten your hard drive and reinstall Mac OS X from scratch -- THEN follow my Paragon procedures in order, which is really stupid. However, you could also hit up the people at the Genius Bar and see what they can figure out.

An aside: jumping through this many hoops to get an external NTFS hard drive to work is absolutely ridiculous. Apple used to recognize Windows file systems easily. Even when it didn't, finding the driver that made it work was a piece of cake. Paragon USED to work until High Sierra broke it. Mounty and Tuxera weren't solutions, either.

I'm glad I conquered this but it's frustrating, especially when Apple's motto use to be "ease of use".

Will do but if Mounty and several versions of Paragon aren't picking up the drive, then it has to be a bug with in High Sierra. Additionally, I will create another user account and see if that resolves it. It might be that there's a USB bus issue that got scrambled. If that doesn't work, I'm going full clean install after wiping the drive.

Lastly, why is this marked as "Solved" when it isn't actually "solved"?

Erased my hard drive, started from scratch, installed High Sierra. 8 TB drive detected. Paragon was then installed -- and it broke the OS to the point where I'm getting 100 percent on the startup progress bar and can't get to the login screen.

So, basically, High Sierra has an issue with Paragon now. This is not "solved".

Two more things tried:

• Exchanging power supplies
• Exchanging USB cables

As mentioned, every other computer mounts the drive. My MacBook Air can read from it and, if I install Paragon, it can read and write. My PC can mount, read and write.

The Mac Mini simply does not like it and the Paragon Drivers, for whatever reason, have just stopped working altogether.

Please help...

They are updated. I have the drivers for "10.10 and above" which is all Seagate makes. Unless I'm missing something.

Yep. 15.2.319.

...and failure. Tuxera gives "Error while mounting disk: Operation not permitted".

Creating a new account does nothing either.
