App Store applications are required to be sandboxed.) Most apps you download onto your Mac will be written in Objective C and/or C++, but a few popular apps (Minecraft, for example) are written in Java. The fact that you installed it on your computer is what gives it that access. Doesn't matter what language it's written in.
#WHAT IS JAVA USED FOR ON MY MAC FULL#
The headlines shouted "JAVA UNSAFE!!!" They should have said, "On reflection, it turns out that Java's security is almost but not quite as bullet-proof as previously believed."īut remember, when you download an application to run it on your computer, it has full access to everything. Flaws were found in the JRE (Java Runtime Environment) that did allow carefully crafted Java applets to break out of the sandbox and gain full access to your computer. An embedded Java application can indeed provide fancier graphics than your browser natively supports, but has no direct access to your filesystem and cannot affect anything outside that web page's sandbox.Īt least in theory. Java was widely believed to be immune to these problems.

The unintended consequence was that it had unrestricted ability to install malware on your system. The intent was to allow fancier graphics than your browser natively allowed. It allowed a website to download compiled native code to your machine and run it there, where it had the full run of your system.
For example, ActiveX was one of Microsoft's more idiotic ideas.
It doesn't matter if it's written in C or C# or Java or Assembler, if you didn't download it on purpose from a reputable developer to meet a specific need, it has no business running on your computer.Īs a special case of that, it is insane to tell your browser it has permission to download and run any application that a website offers. It doesn't matter whether the program comes to you as an embedded applet on a web page, or come as a. Especially if you don't even know you're doing it. It is insane to go around running every application you come across on the internet. Java is just as safe as any other programming language. It's safe to delete Java as long as you aren't using it.
