Apple has released its macOS Big Sur 11.4 that expands support for external GPUs, fixes bugs in Safari and more. In addition, this update also makes the system more secure by patching an exploit that let sneaky malware take screenshots without the user being aware. Jamf, an Apple-focused mobile device management company, reported that the XCSSET malware was using an exploit to take screenshots of Mac computers without asking for any permission. The malware targets Mac developers to infect mainly Xcode projects, which were later shared on platforms such as Github.
