If you find that your Mac starts to run slowly, or takes a long time to boot, it's likely a storage space issue.Running out of storage space can have a lot of negative effects on your Mac, from slow startup to apps not launching and more.


You should keep some extra free storage space on your Mac, and as to why, let's take a look:

How much free storage space do you need on your Mac?


There are several factors to consider when determining the exact amount of storage you need to keep free on your Mac.It depends on the type of storage, what you often use your Mac for, and more.

In general, you should keep a good portion of your storage device empty, between 5% and 20% of the drive's total storage.Keeping this much free will allow your Mac to be used for temporary files when needed so it can work efficiently.

For example, if you have a 256GB SSD drive on your Mac, you should keep at least 13GB free at all times, preferably more.

Why does your Mac need extra free storage?

Most SSDs these days will work just fine even if you pack them to the max, since most manufacturers keep a portion of the hard drive empty for temporary files and boot issues.However, depending on your usage, this can still cause many problems with your Mac.Some of them are very obvious, while others may be hidden.

Here are the biggest reasons why you should keep free storage space on your Mac:

1. Free storage space keeps your Mac from slowing down

If your Mac is running low on storage, the first thing that will be affected will be the speed of your Mac.You'll notice that everything from booting up the Mac to loading applications runs slower.You'll also notice that Finder gets stuck or fails to load folders.If that's the case, it's best to free up some space right away to make sure your Mac is back to normal.

2. Your system will have room for temporary files


Macs use free storage space for temporary files and "swap" files.The swap file is used when memory is under pressure to write data to the drive.When you're doing a memory-intensive task, like editing a movie, it can take up a lot of storage space.

In this case, it's always beneficial to keep some free storage space to allow your Mac to function properly with temporary files.Otherwise, you'll find that your Mac might stop working when you throw an intensive task at it, and for that, you'll need to restart it to get it working again.

3. Smoothly upgrade your Mac software

Today, many software updates can take up gigabytes of data, which is why there must be free storage space to allow them to be downloaded.If you update your Mac's software to the latest version of macOS every year, you'll find that each installer is about 12GB in size and requires about 35GB to 45GB of free storage to actually install.So if you don't have the free storage space you need, you may not be able to upgrade to the latest version of MacOS.

4. Fewer startup problems

Another consequence of the lack of storage space on your Mac is that it can interfere with the startup process of your Mac.A slow startup can be a nuisance, especially when you want to get work done quickly.

How to check storage space on your Mac


macOS gives you a clear view of the available storage space on your Mac from the Apple menu.If you go to the Apple menu, click "About This Mac" to see it.Click "Storage" to see your usage profile.This is also broken down by different types of files, which allows you to see which files are taking up the most storage space.

How to Free Up Mac Disk Space

If your storage space does fill up, you might want to start freeing up some space on your Mac.This is easier said than done, but there are some immediate steps you can take.For example, enabling iCloud Drive on your Mac lets you move unused files to the cloud.Likewise, you can move non-essential data to an external drive, which will free up your disk space.
