Heck, remind me that I’ll bounty your question if you’re not happy with the answers it gets once it gets posted. Just be sure to get any sysdiagnose before you restart next time you catch this pattern, and get a second sysdiagnose after you reboot. | |

| Jan 19, 2019 at 22:30 | comment | added | Gilby | Understanding what is using Wired has been bugging me for some time and I have not made much progress :( In the Activity Monitor screenshot, the numbers add up (App memory + Wired + Compressed + Cached = Physical). I will look further (but it won't be quick). | |

@Gilby Thank you for the comments. I would love to see the results of sysdiagnose FileZilla or whatever program / process that is using the most wired memory. In this question we’re lacking that level of detail. I bet one of us learns a lot, and I’m hoping it’s me. I can’t reproduce this scenario to validate my assumption that wired is being reported wrongly and there’s actually not a problem.

Not much to be tossed out as required. 4. High wired will certainly cause issues (because it can't be paged out) if you try and run a memory hungry app. | |
