Paragon NTFS for Mac promises read/write access to any version of Windows NTFS drives in your macOS for as low as $14.99 if you purchase the five-license pack. Founded by a group of MIPT students in 1994, Germany-based software company Paragon Software Group develops hard drive management tools such as partition managers, boot managers, backup software and system duplication software alongside a driver for Mac that bridges the gap between Mac and Windows devices. If you’ve ever tried to open a Windows file on a Mac – or vice versa – then you’ll already know the frustratingly impossible task that this is, especially if you’re using the drive format NTFS or New Technologies File System. One hopes that the app cleans up after itself after writing all these test blocks. You really have to wonder about the safety of using this app. If he DIDN'T know these temp folders existed, that doesn't speak well either. If the developer does know that and STILL chose to write to protected system folders, shame on him.

That is what those folders are there for, for applications to write temporary files. private/tmp AND /private/var/tmp AND TMPDIR environment variable. Why in the world would you risk writing huge blocks of test data to sensitive system folders?Ģ) In any version of OS X, there are defined temporary folders that can be written too that the current user has permission to access, that the program could have used without having to ask the user. That indicates to me very lazy and/or lack of knowledge programming on the part of the developer, neither of which is a good sign for a utility program.ġ) given it works in Yosemite, but not El Cap when you just select a drive, likely indicates that if SIP is enabled (System Integrity Protection), the program fails that means the program is attempting to write to system folders (which under Yosemite, was still possible). User says in El Cap, one must select a folder (not a disk) otherwise the app reports the disk is locked, but it worked fine in Yosemite. Disclaimer, I have not used the app, just commenting on what has been stated here.
