CleanSpace guides

How Mac storage really works

Where the space went, and how to get it back by hand. You do not need an app to follow any of this — CleanSpace is the shortcut.

Storage

How to free up disk space on a Mac, ranked by how much it returns

Most guides list twenty tips in no particular order. Here they are ordered by what they actually recover.

Storage

Mac disk space analyzers, and how to read one properly

A treemap tells you where the space is. It does not tell you what is safe to delete, and confusing the two is how people break things.

Apps

CleanMyMac vs CleanSpace, compared honestly

One is a mature suite on a subscription. The other is a rules engine you buy once. The right answer depends on which trade you would rather make.

Apps

DaisyDisk vs CleanSpace, and why you might want both

These two apps are usually put in the same category and they are not really competitors. One answers where the space went. The other answers what to do about it.

Apps

Mac cleaner apps, compared without the hype

Most of what cleaner apps charge for, macOS or a free tool already does. Here is the part that is genuinely worth paying for, and how to tell.

Security

Are Mac cleaner apps safe, or are they all scams?

The category earned its reputation honestly. Some of the apps in it are fine, and there is a short test that separates them.

Storage

A storage cleanup routine for a MacBook that actually sticks

Clearing 60 GB once is easy. Staying clear is the hard part, and it is a schedule rather than a heroic afternoon.

Storage

What is System Data on a Mac, and how do you shrink it?

macOS puts tens of gigabytes in a category it refuses to explain. Here is what is actually in there, and how to clear each part of it yourself.

Storage

Your startup disk is almost full: what to do, in order

The warning always arrives at the worst moment. This is the order I work through it, starting with the things that cost you nothing.

Storage

Purgeable space on a Mac, and why you cannot delete it

Your Mac says 30 GB free. Finder says 90 GB. Neither is lying, and the difference has a name.

Apps

How to uninstall a Mac app properly, leftovers and all

Dragging to the Trash removes the app. It does not remove the eleven other places the app wrote to.

Storage

Inside the Mac Library folder: what is safe to delete

Apple hides this folder for a reason, and the reason is not that it is dangerous. It is that most of it is boring.

Maintenance

How to clear cache on a Mac without breaking anything

Clearing caches is the most over-recommended fix on the internet. It works, occasionally, and it is worth knowing when.

Storage

Time Machine local snapshots are eating your disk

Your backup drive has been unplugged for six months. Time Machine has been backing up anyway, onto the disk you are trying to free.

Storage

How to find the biggest files on your Mac

Every gigabyte you are missing is in a file somewhere. Here are four ways to find it, none of which need a download.

Storage

How to find duplicate files on a Mac, free

Most duplicate finders match on name and size. That is how people end up deleting the wrong copy.

Apps

Xcode is using 60 GB. Here is what you can delete

If Xcode is installed, it is almost certainly the largest thing on your disk. Nearly all of it regenerates.

The honest answer is "probably not, and here is how to check what you already have".

Security

What starts up with your Mac, and how to stop it

There is the list Apple shows you, and there is the real list. They are not the same length.

Hardware

Living with a 256 GB MacBook

A 256 GB Mac is entirely workable. It just needs decisions made once rather than a panic every few months.

Maintenance

When the Trash will not empty on a Mac

"The operation cannot be completed because the item is in use." Here is which item, and how to find out.

Maintenance

Why your Mac has less space after a macOS update

You updated macOS and lost 25 GB. Most of it comes back on its own — but not all of it, and not immediately.

Maintenance

Your Mac is slow. Here is what to actually check

Almost every "speed up your Mac" list starts with clearing caches. That is roughly the least likely cause.

Storage

iPhone backups are quietly filling your Mac

Every phone you have ever plugged in may still have a full backup sitting in your home folder.
