Use with caution & note that it might break some running programs. I highly recommend making a backup before proceeding further.īecause the computer was sluggish and I thought freeing some space will make it faster ( which was actually true ) I decided to empty it! Reading around the internet some people say it’s bad practice to delete anything there as it may cause issues with your programs or lose unsaved data. In my case the largest folder ( sometimes over 80gb ) was /private/var/tmp. I scanned the storage using a small app called “ OmniDiskSweeper” which allowed me to find the root of lost storage. Unfortunately no actions are available in the System section so here’s what I’ve done: The basic OS X storage scanner shows you Applications, Photos, Videos, etc and System section. This is great, and a step forward, but I have found most of my space gets lost in temporary files. In the latest version, macOS Sierra, they even included a “Storage manager” to help you clean unused files.
I've been using their test versions for years and still prefer it for some purposes on the net.Many times, especially after long usage, Mac OS X eats up a lot of space.
Provided kindly for free, this is a reasonable, colorful, useful way to dig around on your drives to find what's taking up all your drive space and how much of it, starting with the invisible files and folders we normally don't see.Īlso note that the free OmniWeb browser is still around and kept up-to-date. (Or you can proceed without granting OmniDiskSweeper permission to scan those folders, in which case OmniDiskSweeper won’t be able to tell you how large they are.)"
If you wish, you can avoid these prompts by granting OmniDiskSweeper full disk access under System Preferences > Security & Privacy > Privacy. When OmniDiskSweeper scans the files in your home folder, it triggers these alerts: so we’ve added a description that explains that OmniDiskSweeper doesn’t actually open any of the files it scans, it just lists those files for you to review.
It requires at least macOS 10.13 High Sierra. I tried once and there was no problem, but dango, it sure worked fast and there is no getting files back when deleted that way (except from backup). I do not use OmniDiskSweep for deleting anything.
It used to update automatically, but that stopped happening somewhere along the way. I have to close the window for a drive and start new sweeps. OmniDiskSweep is not automatically updating as files move around. There is one problem I am having, I don't know if it affects anyone else.
It really helps me see where disks are getting crowded and to keep my files organized. OmniDiskSweep always is running on one of the macOS desktops. It is not the most complicated thing in the world, but it is not the simplest either. Every drive has some primary files, all the HDs have backups of files that are primary on other drives. The primary files I use are distributed among the five drives, and they all are backed up to other drives. In addition to macOS, I have two critical virtual servers running as guest OSs (Debian) under VMWARE Fusion. The others were ok, but I find OmniDiskSweep the most helpful. I tied three other products before this one. Since the directories and files are sorted by size, you get to quickly zoom in on the big files that are taking up all the space.
It's a fast, easy way to find those large files cluttering up your drive and clearing them out for new, better things. OmniDiskSweeper is really great at what it does: showing you the files on your drive, in descending order by size, and letting you delete them easily! It scans your disks as quickly as possible and shows you the facts - if a file doesn't make the cut to stay, just click the big Delete button and be done with it.
