![]() ![]() Little Flocker’s Simple Mode makes the dialogs easier for anyone to grok. (Little Flocker had the original name of FlockFlock in tribute, but it was clearly too confusing.) Rather than monitor for file accesses, it looks for software that’s installing itself in such a way that it will always be running and will fire up again after a system reboot. BlockBlock tackles persistent installationsīlockBlock (donationware) carves out a different aspect of unwanted app installation and execution. ![]() I just had to restart a few times, and now I have a stable bit of protection that makes me more confident about my Mac’s resistance against future threats. In my testing, I kept confounding Zdziarski with the edge cases my system threw up, but I didn’t lose any data. Like any software of this kind that extends the system at the kernel level-with Apple’s permission, as Zdziarski had to apply for and receive a special signing privilege-you should make sure you have good backups and the time to read the manual and train it up. At Zdziarski’s directions, I collapsed those to a single rule that lets both programs access anything from the root directory on down. I found that Learning Mode creates dozens and dozens of rules for some apps, like System Information and Finder, because it accesses many different deep subdirectories. It comes with a default set of system rules that allow macOS to carry out its known activities. You can review and import these rules, then modify them. Once you’re satisfied everything as it should be, you disable Learning Mode, and the app presents a list of rules it has intuited. Pretty sure any time I’m running a Flash installer, I want to take a good long look at what it thinks it’s doing. I lobbied Zdziarski to change the default behavior from 30 seconds in this mode to a dialog that alerts users and which can be dismissed after startup is done-because my startup isn’t minutes long before my system is usable, but it seems to take 2 to 4 minutes before every menubar utility and all the background gewgaws have fired up. mp3).Īfter installation, which requires a restart, Little Flocker launches in Learning Mode, where it watches what apps try to open during your normal startup process. Instead, it restricts apps to modifying only specific file paths, or accessing particular extension types (like. There are so many potential vectors for that, and the barn door is always shut after the cow is out. The app isn’t designed like anti-malware software to prevent ransomware and other local-file manipulating horrors from infecting your computer. (It’s just $10 for five-computer personal license and $20 for a single-computer business license.) Now that I’ve used its stable 1.0 version for a while, I can more generally recommend it to those willing to go through the training stage and learning curve. Little Snitch (from Objective Development) is to apps accessing the local network and the Internet. Little Flocker is to apps opening files what the network-watching utility (He’sīeen a guest on the Macworld podcast and we plan to invite him back soon.) As it went into beta and now into version 1.0, I’ve been running it full time on my main office Mac (which I updated to Sierra just before Apple dropped the official release), and providing feedback to its developer, security expert Jonathan Zdziarski. Little Flocker in a previous column, noted above, at which point the software was still in its alpha stage of development, and I was too nervous to run it routinely. Some programmers find Apple’s oversight and control insufferable, or prefer to not pay the $99 a year membership fee and hop thru the hoops. Little Flocker and BlockBlock go far beyond that, but anyone reading this column likely wants more assurances about what’s running on their Mac than what Apple provides and controls, especially if you need to install unsigned software, as I do. You could limit to App Store apps only, good for inexperienced users, kids, and perhaps parents App Store and Identified Developers, which added software that had a registered Apple developer attached who had used Apple’s processes to sign the app cryptographically to show it hadn’t been tampered with and identify its origins and Anywhere, which allowed all unsigned software to run. Three radio buttons in the Security & Privacy system preference pane that control which apps could launch by default. For instance, across several releases of Mac OS X, Apple had a series of Since then, I’ve tested one of the packages extensively, Little Flocker, and am taking a delighted hard look at another, BlockBlock.Īpple errs on the side of reducing problems for the majority of its customers, who don’t want to manage a computer: they want to use it. Noted a couple of new kinds of tools that would be available for macOS that go beyond Apple’s built-in support to block malicious activity and protect your files.
