MAC OSC SIERRA IS ASKING FOR PASSWORD TO DELETE DOCUMENTS MAC OS X

Then in Mac OS X 10.2, which arrived in 2002, the system got even cleverer at avoiding fragmentation. HFS+, which was introduced in 1998, could defrag files on the fly thanks to Hot File Clustering. Mac do not need to be defragmented because the file system (initially HFS+ and more recently APFS) prevents fragmentation and automatically defrags files if necessary - if the file has more than eight fragments, or is smaller than 20MB, it will be automatically defragged. If you are running High Sierra or Mojave, and your file system has been changed to Apple’s newer APFS, you will not be able to use any third party tools to defrag your Mac as there are none that work.

Your Mac operating system does not predate 2002 (if it does can we suggest you update your Mac!).

If any of the following applies to you we would suggest that defraging is not the solution to your problem: This only applies to hard drives though, and not as much as it used to: NTFS (the more modern filesystem) doesn’t tend towards fragmentation as much as FAT-32 did (the older file system).Īlso, modern SSDs (aka Flash drives) don’t need to be defragged, in fact doing so can damage them, as we will explain below.Īs we’ll explain below, you probably don’t need to defrag your Mac. The PC knows where the parts of the file are, but if there are a lot of fragmented files it can take a long time for it to find all the necessary parts before opening the file.īy defragging the drive the files are all shuffled back in order to fill any holes that have appeared when files were deleted - which should avoid files being fragmented in future - and fragmented files are put together. If you want to save a large file - a video, for example - it might need to be spread, or fragmented, over a number of these gaps. (Kind of like in the image below, which incidentally is of a Mac app that is no longer available). If you’ve been using a disk for a long time there may be lots of gaps left by files you have deleted, rather than leaving these gaps vacant, when you save a file Windows will put it to one of these gaps. When a file is saved to a PC hard drive it fills the available space in an efficient way.

In this article we will explain why you probably don’t need to defrag your Mac, the rare occasions when you might need to defrag a Mac, what might really be causing the issues you are facing, and how to defrag a Mac if that is what needs doing after all.īut before we go on to that, we’ll start by explaining how data is written to a drive, why PCs need to be defragged, and why things are different for Macs.

If you have an SSD defragging will have no benefits and will damage your drive.Defragging can damage a drive because moving files around wears the drive out.Modern Macs defrag files automatically, they’ve done this since OS X 10.2 launched in 2002.

Macs don't typically experience the kind of fragmentation that Windows PCs are prone to.

Well, there are a number of reasons why Macs don't offer a defrag function:

Windows has always had disk defragging software - in fact, Windows 10 (and Windows 8 and Windows 7) automatically defrags on a weekly basis (you’ll find it referred to as "Optimise Disk" in recent OS release, you can adjust how often these defrags happen).Īpple, on the other hand, has never included defragging software in macOS. You think back to what you used to do on your old PC and remember disk defragging - that should have the same effect on Macs, right? After all, it made your old PC run a lot faster. So your Mac isn't performing as well as it used to and needs a speed boost.
