9.5 is out :
http://dl.paragon-software.com/demo/ntfsmac_trial.dmg

Notice to version numbers. 8.0, 9.0. This company never try to fix anything with their software. I have reported some finding to them, they said that they will fix them and closed the cases but none of them fixed. Instead, they released a new version. I do not believe that there's anything new with this version, because NTFS is NTFS. New versions are to want more money from their old customers. If you pay an upgrade price for a new version, later they starts to sell the new version for the upgrade price you paid.

This software is dangerous! My bootcamp volume corrupted many many times and I had to repair it. If you report these kind of problem to their tech support, they suggest you to repair the disk with Disk Utility. Why would I have to repair my NTFS volume every time?

I uninstalled it. Dangerous software and poor support. That's it!

NTFS for Mac transfers files between Snow Leopard and NTFS-formatted external hard drives perfectly fine. In fact, I think it does a very good job of it.

However, users planning to use this to access a Boot Camp partition, beware!

When I have tried moving something from the Windows partition to the mac partition (which I have done 3 times), I often get strange errors like "-36". Sometimes it takes a few errors, in the most recent incident it only took one, but the common result is an unbootable Windows partition with at least a corrupted registry.

Strangely enough, after the NTFS partition is rendered unbootable, I can copy files from it onto my mac partition just fine. Ironically, that is just what I am doing right now, saving my personal documents before I am forced to reinstall Windows.

Conclusion? This works awesome with external hard drives. Never once have I gotten an error of any kind. But if you want to use this with your Windows for Boot Camp, you might be in for a lot of pain.

In every aspect, this software is far better than Tuxera NTFS.
- It's above all much faster
- It's more reliable and easier to use
- Better features
- No error messages like -36 and no file write permission error which I have encountered with Tuxera NTFS

I moved from Windows Vista to Macbook Pro and have a home network of Windows Machines and USB storage drives formatted as NTFS used for sharing and backups. I had several programs that would only run under Windows so Installed Vista (later Windows 7) under Bootcamp.

Being somewhat naive about Mac, I didn't find the free NTFS nor become aware of the virtual machine (VM) options for MAC like VMware and Parallels (I tried Oracle/Sun's free VM but it was much too technical for me). Here's my experience with NTFS for Mac and the companion HFS for Windows.

1. HFS for Windows does not support encrypted Mac disks. If you select Filevault (may have been the Mac default), the Mac disks from Windows show up as Bands and you can't read them from Windows.

2. Both NTFS for MAC and HFS for Windows are disabled when running under a virtual machine, and the functions they perform are provided by the 2 VM's I tested, but only when those VM's and virtual OS (Windows) are running.

3. However, NTFS for MAC will give you read/write access when you don't want to boot up or allocate the resources for a VM, for example, just to access an external USB Drive or a file under the VM (Or Bootcamp). Running the VM, even on dual 2.53GHZ processors and 4GB of memory, is resource intensive. You have the usual slow boot and shutdown times of Windows and MACOS slows down noticeably and Windows is often very slow. (D) not to install HFS for Windows under a VM, only under Bootcamp.

4. Paragon's Tech support says installing HFS for WIndows under the VM can cause a BSOD (Windows Blue Screen of Death). I installed it under Bootcamp, then installed the VM and didn't see this problem.

5. Paragon tech support can be slow to respond, they provide only e-mail support for free for a very limited time (though they did respond beyond that timeframe for an issue opened in the timeframe) and there are occasionally minor language issues.

6. Paragon's refund policy is a short 30 days after purchase, so if you encounter a problem like I did, you may have to ask for a refund first and then perhaps work the issue with tech support in parallel. I asked for an extension of the refund window given the lack of warning in marketing materials about two common conditions (use of a VM and encryption of MAC disks), but they repeatedly refused.

7. I asked Paragon to post items 1-4 on their marketing materials so customers are not surprised, but haven't got confirmation yet that they will do it.

8. I did not have any stability problems with the software. I didn't measure the performance but it didn't notice any delays vs. native access or from a VM.

9. The instructions for installing HFS for Windows (Read only) weren't very clear. Despite re-reading the doc and help files I had to contact technical support to figure it out.

I've noticed a few issues relating to Paragon's NTFS for Mac and I just wanted to share them.

(1) Incompatible with VMware Fusion: In order to run VMware Fusion I have to go to Disk Utility and unmount the volume before I can run it.

(2) Safari Download Issue: When attempting to download a file via Safari, if the NTFS volume is mounted on the desktop the Safari will hang for about 15 seconds before it continues the download normally.

(3) Name In Finder: Though the volume's name is "Mimmic" both in Disk Utility and in Windows, it's mounted as "Mimmic 1" and no amount of changing on my part can fix this. It will change temporarily but the next time I mount the volume it will be "Mimmic 1" all over again.

(4) Finder Eject: I cannot unmount the volume by key command or dragging to the trash, I have to unmount it via Disk Utility.

It's a good little utility and once these issues are ironed out it'll be an invaluable piece of software.
