BlockBlock for Mac

Great software, provided without charge, by a highly respected developer. This is extremely useful.

The current version is 0.9.9.1

These seems very interesting and potentially very useful. I have frequently wanted to watch for things that apps set and store on my system, now it's just a matter of seeing how far this app takes this concept. I've used FSMonitor.app to watch apps while they're active, but to have a log to go back to and find out what apps are doing and where they're sticking stuff will be fantastic. @developer, can you give us more details about this app as far as what it will track wrt "persistence locations?"

Users should remember that it's still a beta, so there might still be some problems, but after some glitches and serious bugs in previous version, v0.9.6 and now v0.9.7 have been running great on my system 10.11.6. Needless to say, this is a very valuable security app. Everyone should use it.

Ervins, Thanks for your review and for alerting us to the seemingly useful, and possibly great security apps at the developers site‼️ After I test them (there are 10 programs), I will review them here.

In reading his notes and "readme" files for each app, Patrick conveys a real concern with security; not like some who hype their products as ‘the last word’ in Mac security. This developer points out what he sees as both strengths AND weaknesses with his apps –– and his desire to improve them all as he moves forward. Very impressive array of programs and extremely detailed infos on all of his apps.

“OS X malware and security has been a personal passion for many years. However the more I learned about this topic, the more insecure I felt. Malware for OS X is trivial to write and unfortunately has become ever more pervasive. And, using attacks such as dylib hijacking attackers can easily bypass all current OS X security products.

As an avid Mac user, this worried me, so I decided to do something about it. Initially, this was for somewhat 'selfish' reasons; I simply wanted to write OS X security tools to secure my Mac. But then I thought, "hey, sharing is caring, I should make my tools publicly available, free of charge." This is the idea that drives the website.”

Patrick Wardle

Not to be missed, is his site’s Blog, where you will find an amazing trove of Mac security information, resources and a detailed overview of the ‘Mac malware’ culture we now find ourselves confronted with.

And as you pointed out –– he has a big heart when it comes to pricing :-)
He very quietly points out (at the very bottom of his site pages), that donations are welcome; but nothing is ‘crippled’

Nice find.
