[QUOTE="MacDefender, post: 946237, member: 83059"] I would wager a guess that if you try to copy a bunch of files, you’ll notice a significant amount of extra CPU usage and a slowdown. It’s kind of like BitDefender’s conserve memory mode… a lot of these realtime engines on the Mac simply aren’t optimized for performance. It’s good that it’s not a memory hog though at least! The built in firewall on the Mac is kind of similar to the Windows Firewall — it’s pretty effective but basically inbound-only and doesn’t control outbound traffic. By default, properly signed apps can open ports without warning you, but that’s a setting you can change in macOS. I do think there can be value in adding an outbound control firewall just like on Windows. Little Snitch I think is the best written outbound firewall, but it’s expensive, and quite honestly I think for 99% of people, it will just be a lot of nags/hassle without much benefit unless you are really trying to run somewhat untrusted software and worried about it phoning home. But on the other hand, Macs strongly use process isolation so the alerts can be really fatiguing. For example, even a simple app like Weather might use 3 different processes to fetch different kinds of data. Like one thing nice about macOS Catalina and above’s built in ransomware protection is that if an app tries to look at your photos or documents, that triggers a permissions dialog. It’s like a better / interactive form of Controlled Folder Access. A rogue app can’t steal/upload files from you if it can’t access them in the first place. [/QUOTE]
