Hello All,
I recently upgraded to macOS High Sierra.
Under macOS Sierra I could mount & read my 2TB NTFS external Western Digital Ultra & Regular Passport drives. I've tested them on a Macbook Air running macOS Sierra, they also mount fine.
Since the upgrade to High Sierra the drives appear (in Paragon NTFS & Disk Utility only) but I'm unable to mount them. I've actually upgraded the firmware of the drives (using a PC and going to WD support pages) and they still don't mount.
I'm using a trial version of the Paragon NTFS for Mac 15 (which will last me another few days)
Has anyone had this issue? I'm thinking of taking the time to format my drives from a PC in exFAT format (or at least one of them, to ensure I can use on my work PC)...but that would defeat the purpose of what Paragon praises with the NTFS for Mac 15.
Thanks in advance,
Jon

I installed NTFS for Mac 15 on a MacBook Air (13 inch, 2017) running Mac OSX High Sierra (10.3.2). When I do System Preferences, NTFS for Mac, I immediately get a window that says 'Paragon NTFS for Mac 15 system extensioons is blocked! (I attach a screen snapshot). I try the Allow button in System Preferences, Security & Privacy, General tab, but that does not cure the problem. The external hard drive that I wish to use is a Seagate Free Agent GoGlex 500 GB drive, but the problem that I describe above occurs without even attaching the drive to the USB port.
