When your Mac is slowing down, try this Terminal tip

Watching Apple since 1999. I don't say what they should do. I say what they might do. They sometimes do.

  1. Cache says:

    This actually doesn’t clear memory but disk cache. From the purge man page:

    purge(8) BSD System Manager’s Manual purge(8)

    purge — force disk cache to be purged (flushed and emptied)


    Purge can be used to approximate initial boot conditions with a cold disk buffer cache for performance analysis. It does not affect anonymous memory that has been allocated through malloc, vm_allocate, etc.
