I have recently had an issue I hadn't experienced before regarding the Security and Privacy settings in preferences. I downloaded an app from the Internet (HandBrake) and got it to install. I didn't recall exactly the steps I took, but I had done this before by changing the security settings to allow apps to download from anywhere. I didn't use the app right away. I had changed the security settings back to allow downloads from Mac App Store and identified developers. That is my default setting so common apps like Adobe could download and install. I tried to open Handbrake and was given the warning that it couldn't be opened. I went to security settings, changed to "anywhere" and the app then opened just fine. In the past, once I had installed an app, it would open without any special steps such as changing security settings. Now the app (Handbrake) requires me to go to security settings to access the app. My question is.....do I need to keep the security settings to "anywhere" in order to regularly open the app? For the record, I rarely download apps except from the Mac App Store. So, leaving the settings for "anywhere" doesn't seem to be risky.
