Timemachineeditor1/4/2024 Again, probably won’t work, but it’s quick enough to be worth a try. And that would explain why the TimeMachineEditor workaround fails, since after it does the backup, even though TM is disabled, the local snapshot processes stick around.Īnd it probably won’t work, but you should at least try turning off TM, *rebooting* to make sure the local snapshot processes are quit, and *then* doing a manual backup. If turning off TM, rebooting, and not backing up for a bit to troubleshoot *does* end the local snapshot nightmare, it just means that those processes never properly quit after a backup is done. If you’re still getting the mess even with it turned off, I guess the local snapshot functionality is enabled even with TM disabled. You could try simply turning off TM, rebooting, and not backing up for a couple of hours to troubleshoot. ![]() ![]() I find these entries to be interesting.ġ2/7/15 18:32:47.000 kernel: Sandbox: mtmfs(552) System Policy: deny(1) forbidden-rootless-xattrġ2/7/15 18:32:47.156 mtmfs: could not set attributes on destination file descriptor: Operation not permitted: Operation not permittedġ2/7/15 19:33:33.810 : () Unknown key for Boolean: ForceEnableHackġ2/7/15 19:33:33.810 : () This service is defined to be constantly running and is inherently inefficient. Update: I found the following in system logs. I reinstalled El Capitan, and nothing changed. I’ve contacted AppleCare, and spent a lot of time on this, sending them logs and other data, and I’m waiting to hear back. So it’s clearly Time Machine that’s killing my battery. When I check Activity Monitor, and look at Energy, the app listed as having the highest impact is Time Machine, way above Safari which is the second. It should only do this when it can’t access your Time Machine disk it then copies those snapshots the next time the Time Machine disk is available. But I’m only using the MacBook at my home office, so it’s on the network where my Time Machine backup device is located, and it shouldn’t make local snapshots. These two processes are related to Time Machine, and have something to do with creating local snapshots. Here’s a screenshot from iStat Menus when that happens: One thing I notice is that two processes, mtmd and mtmfs, pop up frequently, using about 100% of CPU (of a core) and do so for a while. I’ve been using it a lot in the past week, and I’ve noticed that I’m getting perhaps 6 hours of battery life, without using a lot of apps. I use it for testing, for taking screenshots, and for working outside my office from time to time. ![]() Now my ADHD brain can work get distracted by writing blog posts in peace.My MacBook is my second computer, and I don’t use it much. It’s possible TimeMachineEditor uses the same method to change settings, but it makes it easier to toggle those settings if there’s an issue. There’s also some Time Machine command line preferences you can set, but I’m not sure how out of date they are, and I’m trying to avoid changing preferences via defaults because as far as I can tell there’s no way to see what was changed and what is the default value without installing another copy of macOS and comparing the two. I kept local snapshots every hour turned on, since making APFS snapshots is noiseless on my Mac’s SSD, and they can get uploaded later to my NAS during the time window I set. You can set calendar intervals, a do-not-backup time range, and some other handy options. ![]() I usually use my AirPod Pro’s noise cancellation, but often I just want to sit in silence with no music, and definitely don’t want to hear the chaotic crunchy sounds of backups happening.Ĭlearly, we need some scheduling to happen! Unfortunately Time Machine is too simple, and you only get 3 options: turn on or off automatic backups, select a location, and exclude folders.Īfter some searching for utilities that aren’t out of date, I found TimeMachineEditor by tclement. The drives were designed for reliability and longevity, not noise reduction. However, my NAS, a Synology DS215+ with two 2TB WD Red HDDs, is very noisy in my small office. It’s saved me once already, when I accidentally deleted my Documents folder while trying to move my stuff to iCloud. I love macOS’s Time Machine backup feature.
