Jonny Evans explains how to rebuild and reindex mailboxes step-by-step in a ComputerWorld post. El Capitan features speed improvements from 4x faster PDF rendering to 1. Tom Nelson, a Macs expert, says that Apple supplies firmware updates from time to time, and although very few people have any trouble after installing them, problems do crop up now and then.

However, this particular problem with EXTREMELY slow time-machine backups persists whatever I try to do, including all four of your suggestions, and I have also followed other several forums with various suggestions, none of which help. It seems to be a serious problem in Mac OS that has not been resolved for a long time. Right now I am in the middle of a new back-up which has been going on for more than five hours, and is still only halfway. I wish Apple would wake up to this one! Someone else in this comment section suggested to disable to low priority throttle.

Everyone can boot into Safe Mode. If the Mac works, safe mode works. Is yopu your name for your Mac? Kind of weird, but ok. I like to run DiskWarrior on Time Machine backups from time to time. Optimizing the huge TM directories has helped me when TM seems slower than it should be.

OMG thank you so much that is a fantastic tip. Thank you so so much!!! I have spent a ridiculous amount of time and have tried so many different ways to get Time Machine Backups to work properly, this has improved the speed x10 at least — Finally some relief :.

This command does seem to be helping. I bought a new 8TB backup disk for my iMac and the initial backup of about 2 TB worth of data ran for over 10 days and had only backed up about GB. At that rate, it would take about two months to complete. If you look at the provided command:. Note the double-negative, so this in fact lets Time Machine run at full speed. To re-enable throttling, you can simply change the 0 to a 1 :. Holy Crap!!! I understand the purpose of throttling in certain contexts mother-in-law, annoying dog next door, etc.

Left my mac to backup over night yesterday and woke up today to see that just 9 gb!? My god this was wonderful. It takes effect instantly no need to restart the backup and I immediately saw a 50x increase in backup speed. It was looking like it would take close to 20 hours — 10 so far with 12 more showing. I tried this command and it the time immediately dropped to hours but at least I can tell that it is moving much more quickly.

I did notice that while it was off and the backup was running the screensaver was jumpy, so I guess this could be one way macs keep everything running smoothly by keeping some processing power in reserve? The difference in speed is unbelievable. Thank you so much! Can you help a beginner? Where do I go to enter the command: sudo sysctl debug. The first tme I tried this it worked like a charm. This time, however, nothing.
