Firstly, I have a Multiboot system with macOS Sierra on an internal Hard Drive and Windows 10 on an external Solid State Drive. When I installed to BootCamp Support software on my Windows installation it didn't render Windows capable of viewing HFS+ partitions, so I had to install a third-party driver from Paragon for Windows 8. When I first installed Windows on the SSD, my macOS installation was corrupted in that there were many inexplicable bugs that made the system unworkable. I opted to reinstall macOS from a TimeMachine Backup and didn't have any further issues for awhile. But recently, after booting into Windows and going back to macOS, I was unable to open browsers, videos, or music files. I booted back into Windows and tried to view those files and there was no issue. macOS seems to have been corrupted, but why? Did Windows do it? Or did my Paragon HFS+ driver?
