I just opened Activity Monitor - a process called "dasd" is the 5th largest consumer of CPU time. What does it do? Apple does not want you to know. Apple also will not let you disable it. Apple will not even tell you if this process is legitimate (it is signed by "Software Signing" lmao).

    $ man dasd
    No manual entry for dasd

It schedules low-priority background processes.
