Offering a recent experience, I was having trouble mounting an NTFS volume on my MacBook Pro. The volume mounted on my iMac and my backup MacBook, but no on my MBP.
I've own many Mac OS X MacBooks over the years, and each time I got a newer one, I would use Apple's Migration Assistant to move my apps and documents to my newer MacBook.
Over years, I've also installed (and uninstalled) various utilities so that I can write to NTSF volumes, such as MacFuse and Paragon's NTFS. I had deleted these using the vendors own "uninstaller" tools. However, it turns out that there were still components that remained. And because they persisted in my system, Migration Assistant copied them into the Mac OS X system on my new MBP, the NTFS volume wouldn't mount on my MBP.
I spent days trying to find out what was going on, and I finally figured out what the key components were. There were items that remained from the MacFuse installation and from Paragon's NTFS. Using Terminal, I removed them manually.
I posted this in a thread in Apple's Community Support forum, and received additional help from a fellow named Drew who apparently has a lot of experience using terminal. He suggested a few commands to discover what parts of MacFuse and NTFS were installed, and the locations they existed. Sure enough, there were long lists of orphaned parts. It would have taken me days to remove them manually. However, he mentioned the UninstallPKG. The trial version provides three free uninstallation, and so I tried it.
In moments, it removed the orphaned remnants. Additionally, it identified remnants of other packages that I had removed years ago. These remnants could potentially be bloating the OS, and impacting performance. I've purchased a subscription, and I'm removing these remnants as well.
For me, the bottom line is that the UninstallerPKG app if far more efficient than entering commands in Terminal, and it's far safer too.
Nevertheless, it is essential to do a full backup prior to modifying one's installed OS. People need to know what the potential consequences might be. But for those who have some level of technical comfort and knowledge, this utility is a gem.
