NTFS for MAC error

Finally to solve the problem I did the following steps:

1-Retart my MacBook Pro (15inch mid-2012) in recovery mode by pressing cmd + R

2-Re-install Catalina 10.15.7 by clicking on the menu line "re-intall Catalina" apering after step 1

3-De-sactivate the automatic updates

4-Remove "iBoysoft NTFS for Mac" or "Paragon NTFS for mac"

5-Restart my Mac

Now when I plug my NFTS external hard drive to my Mac it is seen normally in the finder.

And when I run Disk Utility, my external hard drive is seen as 'unknow ms_nfts" format.

👋

I ended up just re-installing Catalina. It took less than an hour and everything is back to normal. Obviously I won't be installing the security update again.

You can find the installers here:

https://appleinsider.com/articles/21/12/03/how-to-download-an-old-macos-installer

I also have a 5To Seagate External hard drive formated in NTFS.

NTFS for Mac 15´´ mi-2012 works on Catalina only if you re-install Catalina 10.15.7 and do not accept the latest update after the re-instlation.

As soon as you accept the latest update on Catalina 10.15.7 you won’t be able to mount a NTFS disk witk NTFS for mac or iBoyNTFS or Disk Utility.

My concern is how long would I stay with my Catalina 10.15.7 not updated?

Having a mac open to security breach is bad.

Once on a blue moon I would have to accept the latest updates to see if Apple has corrected the issue… And if not then do a re-install.

I've contacted Paragon. They indicated they are waiting for the next Apple IOS update/patch to fix the issue. They did provide instructions for manually mounting the NTFS HDD using the terminal service but it doesn't work for me.

Upgrading to Big Sur 11.6.5, uninstalling and reinstalling Paragon NTFS for mac restored read/write access for me. If your hardware only supports os's up to Catalina, you'll probably have to either wait for a patch or try a Catalina reinstall.

Until then, you might try disabling anti-virus software, uninstalling and re-installing the latest Paragon or Tuxera software just for the heck of it. Not sure if it's related, but software I use to communicate with an external Sony PDW-U4 XDCAM drive (which uses a proprietary Sony format to write to optical discs, not NTFS) wouldn't allow write access even after installing Big Sur until I disabled Sophos. I didn't try this before upgrading to Big Sur, so I can't say if it will work. Good luck!

Thx. Unfortunately, my Mac is old enough to only support Catalina. Fortunately, I was able to get the manual mount instructions from Paragon to work with a little assistance from them. The instructions only seem to work on Seagate HDDs though as my Silicon Power HDD would not manually mount. I get the error: “Bad Vendor.” I am waiting to hear back from Paragon for that. Here are the instructions provided by Paragon:

Dear Customer,

After the latest macOS 10.15.7 Catalina Security Update 2022-003 (19H1824), issues have been reported with mounting NTFS volumes using the NTFS for Mac driver. The Development team were able to reproduce and confirm the issue. We expect it to be fixed in the next macOS updates.

For now, the following workaround can be tried (I used NTFS version 15.9.329 I got from the Seagate website):

1) Make sure you're using Microsoft NTFS for Mac by Paragon Software build 15.9.314

It can be downloaded from the ParagonBox user portal if you have a license registered there or directly from the site:

https://www.paragon-software.com/home/ntfs-mac/

Be sure to uninstall any previous versions as described below:

https://kb.paragon-software.com/article/4500

2) Connect the drive containing the NTFS partition, and make sure the partition is not mounted.

3) Open the Terminal utility (Application -> Utilities -> Terminal) and perform the following command to create a mountpoint:

sudo mkdir /Volumes/ntfs

4) Run the following command:

diskutil list

and note the NTFS partition's Identifier (disk0s3, for instance)

5) Run the following command to mount it:

sudo /Library/Filesystems/ufsd_NTFS.fs/Contents/Resources/mount_ufsd_NTFS /dev/diskXsY/Volumes/ntfs

where diskXsY - the NTFS partition from the previous step

(for instance)

sudo /Library/Filesystems/ufsd_NTFS.fs/Contents/Resources/mount_ufsd_NTFS /dev/disk0s3/Volumes/ntfs

Yep. Agree. All but one HDD are now operational. I'm waiting to hear back from Paragon regarding the "Bad Vendor" error for my Silicon Power HDD. I may just recover it to copy data from the other 5T HDD if I don't get a workable response from Paragon. Cheers.

I have the same problem. Here they suggested checking the disk in Safe Mode, NTFS is not visible. I have a second OS on the same computer and this is the original Snow Leopard where all NTFS formatted disks are served and edited using Tuxera Disk Manager.

But like everyone else in MACOS CATALINA does not allow mounting and, accordingly, the disk is not visible in the Finder. Mounting instructions in Terminal via

sudo nano /etc/fstab

LABEL = Tracy none ntfc rw,auto,nobrowse

don't help. Useless!

I installed the 2022-003 security patch and it had no affect. I still am able to manually mount my HDD using the terminal input commands Paragon had provided and I had posted in a previous response to this thread.

For clarification: OS Catalina. Mounts in read only after latest OS Catalina update. Will mount in read/write manually using Paragon provided terminal commands.

Hi Rafael, it did work, thx a lot!

Meaning we should hold off with 2022-003 patch for now.

I will be following this post, maybe someone would post here if either Apple or Paragon comes with a working solution.

Thx again!

Once you re-install Catalina make sure that in System Preferences/Software Update/Advanced the option to "Install system data files and security updates" is unchecked.

Since I re-installed Catalina over 10 days ago I haven't had any more trouble regarding NTFS drives. I still have the security update pending in Software Update though.

re-installed Catalina again, drives are showing but write protected... so some progress but not where it should be.

Patch 003 is still showing as pending and Macbook (2014 MBPro) is set to prevent auto-update.

Maybe delete and re-install Paragon? version is 15.5.106

Happy evening everyone

ok, story seems to be successful for me: I reinstalled first Catalina and now Paragon using the Paragon "uninstall" feature: R/W works for NTSF volumes again :-)))))

I will be keeping hands-off from the 2022/003 update for now...

Maybe someone posting here when either Paragon or Apple has a patch which does the trick.

Thx to all the great advice and friendly help, almost around the clock!

Stay safe and healthy!

It seems like a security update to Catalina will arrive soon, to patch the 0-day that's currently only patched in Monterey, and not in BigSur nor Catalina. Currently they are working on the patch for BigSur

https://www.macworld.com/article/630407/macos-big-sur-11-6-6-security-updates.html

"Security Update 2022-004 for Catalina will presumably arrive shortly as well."

Let's hope they also patch the broken NTFS in that update....

I just tried the Paragon Software 15.9.366 is 100% work on Catalina Security Update 2022-003!

I uninstall the current of https://kb.paragon-software.com/article/8468 at first > update the Catalina Security Update 2022-003 on mac > install the "Paragon Software 15.9.366" (download by https://kb.paragon-software.com/article/8468 ).

*may be a problem/not work at open the Microsoft NTFS for Mac first time, try relaunch it and open the Preferences and press "check for updates now", all become work automatic.
