What Is Startup Disk on Mac?

Like a Windows startup disk, the startup disk on your Mac is the disk that saved the operating system on your Mac. It is an important disk on your computer. If the operating system on the disk is corrupted or even the startup disk is damaged, your Mac computer will not boot normally.

What Is Taking Up Space on Your Mac Startup Disk?

As you know, a Mac computer’s disk is usually not as large as a Windows computer’s disk. As of 2020, Apple has improved the disk capacity and the maximum disk size can reach up to 8TB. But they are the Pro series, which are not widely used.

Most of the time, you should not worry about the disk space issue because macOS always do work online. This will not take up much disk space. However, what’s going on if you see a pop-up alert saying Your startup disk is almost full?

At this time, you should know what is taking up space on the startup disk of your Mac and then take some measures to clear the startup disk.

The hidden website cache takes much space on the startup disk. For example, statistics show that Google Chrome can create numerous cache folders after you visit some web sites. The size of the cache for one site can even reach up to 9 GB. This is quite surprising, but it is true.

As time goes on, the free space on the startup disk becomes less and less. One day, you may receive the startup disk full alert.

Besides, when a warning of Your disk is almost full pops up, it also means that there is not enough space on your Mac. It is equal to startup disk full. Likewise, you need to remove some files to free up disk space on your Mac computer.

What Does It Mean When Your Startup Disk Is Full?

When does it mean when you receive your startup disk is almost full alert?

It has two main influences:

1. You will soon run out of space on the startup disk.

Your startup disk is almost full is an early warning for you. It reminds you of cleaning up the startup disk. However, if you continue to use your Mac without cleaning up disk space, more and more data will be saved to the startup disk. One day, your Mac will run out of space and you will not use the machine as normal.

2. Your Mac computer will run slowly.

Some of you may think that your Mac computer will not be affected when there is space in the startup disk no matter it is much or less. It is wrong.

A Mac computer can convert the available free space on the startup disk into virtual memory that you use for day-to-day operations. In theory, there should be at least 10% of free disk space for your Mac to operate. If not, your Mac computer will run slowly and even face big trouble like Mac frozen.

When the machine detects that the available space on the startup disk is insufficient, it will give you a warning. This aims to remind you it’s time to clear the startup disk on your Mac.

What should you do when your startup disk is full on your Mac? In the following part, we will show you some solutions.

Summary :

Many computer users find that the hard drive is filled up and they may wonder what is taking up space on the hard drive and how to clean up the hard drive. This article will solve these problems.

What Is Taking up Space on My Hard Drive

Many computer users may find that their hard drives are filled up without reasons after the computer is used for a while. And at last, low disk space error may come up (especially partition C). This problem will affect computer performance. For example: apps or files can't be downloaded, the computer gives no response to your command or it gives a delayed response.

Then, what cause this problem? Or what is taking up space on my hard drive? Many users may ask problems like these. Usually, the hard drive space is occupied by system files, installed apps or personal files, backups, virus or other malware, or other unknown files.

How to Check the Hard Drive Space

How can we know what files take up the hard drive space most? Here is a tutorial for how to see what's taking up space on a hard drive on Windows 10.

Step 1: Press Start button, and then navigate to Settings>System >Storage.

Step 2: Click a disk and then its storage usage will be displayed.

Click What Is Taking up Space on Win10 for more methods.

In general, computer users could check the hard drive space first, and then they can solve the low disk space problem according to the actual storage usage in their computers.

As for how to free up disk space, the following two categories of methods are suggested. And the method with MiniTool Partition Wizard is strongly recommended because it's versed in managing disk space and the ways provided by it can solve the problem radically.

How to Free up Disk Space on Windows

1. Free up Space with Disk Cleanup

Many computer users like to run Disk Cleanup to free up disk space. This is a common way for most of computer users. Right click the disk you want to clean up, and then navigate to Properties>Disk Cleanup. Then check the files you want to delete and click OK to carry out.

However, some users may find that it can't solve the problem fundamentally. Disk cleanup can't relieve the problem at all. Or it relieves slightly but the low disk space problem persists and it relapses after a while.

2. Deal with Personal Files to Free up Disk Space

If there are lots of personal files in hard drive, users can delete the unnecessary files to clean up hard drive. As for the important files, users can transfer them to another hard drive. Or, users can store files like music, movies, photos, etc. on external storage or in the cloud.

In a word, users could delete or transfer all files to another place except the files that must be stored in this disk. (Actually, this method not only can free up disk space, but also can help you to manage or optimize the disk space.)

3. Delete Backups and Reduce Space Used for System Restore

If users have habit of making backups, they could delete the backups to free up disk space. At the same time, system restore points can be automatically created when users install a new app or update and they take up a lot of hard drive space.

So, users can delete the restore points or reduce the hard drive space used for system restore to free up disk space.

Here is a tutorial for deleting restore points and reducing space used for system restore.

Step 1: Open Administrator and right click This PC,and then click Properties from the drop-down menu.

Step 2: Click System protection from the pop-up window to make System Properties window pop up. And then click Configure button.

Step 3: Drag the block to adjust the max space usage for system restore points. Surely, there will be less restore points for system restore if you do so. Or, you can delete all restore points and disable system protection to free up disk space. But if you do so, there is no restore points for system restore.

4. Uninstall Programs

Surely, most of the time, it is programs and games that take upmost of the hard drive space. So, users also can uninstall apps or games that they no longer need to solve this problem. Press Start button and navigate to Settings>Apps>Apps & features to uninstall programs.

5. Run Antivirus Program

Sometimes, a virus or other malware may consume a lot of hard drive space. If you suspect the low disk space is cause by a virus, you can use an antivirus program like Windows Defender to run a virus scan and cleanup.

However, most of the time, the low disk space is not caused by a virus, and running Disk Cleanup or deleting personal files can't solve this problem. Although uninstalling apps can relieve the problem slightly, many users wouldn't like to adopt this method because most programs on the computer are useful and necessary for them.

To solve this problem radically, MiniTool Partition Wizard,professional partition management software, is recommended, which is versed in dealing with problems like this. And it provides you three solutions to clean up hard drive.

The first solution is Space Analyzer, which is similar to the above methods. But it is easier for users to operate. The second and third solutions are extending partition and upgrading to a larger hard drive, respectively. Only the last two methods can radically solve the problem.
