I have used this app since v. 4.x. It has never successfully helped me pull my chestnuts out of the fire because in every release, at least half the functionality simply doesn’t work. For instance, the eDrive fails to function as a startup disk, but the program won't let me delete it and recreate it. The Preference Pane doesn’t install correctly. Background protection scanning will work for weeks, then will stop working, and will never work again. The program creates snapshots that it can’t later open and read. I vowed that I would stop updating this thing half way through v. 9.x, when they wanted more money for a dot-dot release. I lived without the later v. 9.x releases, all the 10.x releases, all the 11.x releases, and all the 12.x releases. Finally, my old 9.x release wouldn’t even launch on a current OS, and I couldn’t use even the modest amount of functionality the program was supplying, so I upgraded to a 13.x release. I was amazed to find that stuff which had been broken in 9.x was still broken, that support for Apple’s current APFS file system is still only partial, at that functionality which had more-or-less worked (like the Preference Pane) was now broken. I have been a customer for seven major releases, but I think that really what I am is a sucker. Nothing ever gets fixed. No, let me try that again: NOTHING EVER GETS FIXED.
