And, perhaps, adopt some more-efficient computing practices for yourself along the way.įirst visit System Preferences –> Users & Accounts, and click the Login tab. The good news: Yes, there are some things you can do. Is there some sort of tune-up you can do to sort it out? Your tech always tells you to just reboot the computer, but there’s got to be more than that.
Remnants from old software may still be running behind the scenes, or you don’t have enough RAM to deal with your OS and workflow. Crashes or misbehaving programs can corrupt the disk directory or application cache files. Sometimes your hard disk (or solid-state drive) gets too full and interferes with normal computer operations.
You may be asking, why does this happen? There are many reasons, but some are more common than others. I see these issues in my IT consulting business regularly. The operating system just starts to feel crufty, and can get worse over time.
Launching and switching programs takes longer, simple tasks become arduous, and the dreaded beach ball of doom appears more often than it did when your machine was new. This can be extremely useful when trying to clear up disk space if you don’t know what is hogging all the room.Macs are solid machines, but just like their owners they have a tendency to get lethargic as they age. The * wildcard will cover all files in your home directory or whatever directory you are currently in, by default the Terminal will launch with your home directory as the pwd (present working directory).Īs you can see, the * allows for a breakdown of the space taken up by which directory. This users home directory takes up 26gb of space!Īnother example, type du -sh * at the terminal. The -s flag is for a summary, and once again the -h flag is for ‘human readable form’, the ~ is your home directory. du – displays disk usage information for each file and directory (ie: home directories, folders, etc) In this case, /dev/disk0s2 is the main hard disk, and 70% of it is in use. You should see something like this:įilesystem Size Used Avail Use% Mounted on The -h flag is for ‘human readable form’ meaning return results in the familiar megabyte/gigabyte format. Df – displays disk usage information based on file system (ie: entire drives, attached media, etc)
