Hi, last month I started to notice, that my 2013 Mac mini started to produce HDD sounds - just like continuously writing data, even if all APPs are closed, immediately after restart, etc. I dont think this is a HDD failure because of the familiar writing sound. I did lot of research in the forums, but didnt find any help. It looks like the kernel_task od launchd are causing it by writing SOME data, even if I dont use the computer for hours. Im desperate about finding whats wrong. Tried to check Activity monitor, which shows this (screenshot attached). The "bytes written" from kernel and launchd are continuously growing to Gigs (the screenshot is after restart). I triend to kill some processes, I tried to stop everything running - can I determine what is the kernel and launchd writing and somehow stop this? Or maybe another process writes? Yeah and I dont have any memory/CPU problem (Kernel CPU around 3%) Im a common user, not a geek, please slowly Thanx for the help.
