From this MiniTool article, you can know what the startup disk on your Mac is, what is taking up space on the Mac startup disk, the influence of startup disk full, and how to clear the startup disk space when the startup disk is full or your disk is almost full on your Mac.
Quick Navigation :
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:
Hard Drive Space Mac
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.
How to Clear the startup Disk?
If you want to clear your Mac startup disk, you need to delete the unnecessary files on it. Before doing this, you can check the storage space on your Mac.
How to Check the Storage Space on Your Mac?
- Click the Apple menu from the top-left corner of the screen.
- Click About This Mac from the drop-down list.
- Switch to the Storage section.
After these three steps, you can see the storage information of your Mac disk, including the files’ types, the free space on the drive, and more.
If your Mac Startup disk is full, you can do these things to free up disk space:
How to Clean the Startup Disk on Your Mac?
- Remove the App Cache from your Mac.
- Empty Trash.
- Delete the unnecessary Time Machine backup snapshots.
- Delete browser cache.
- Remove language packs.
- Use Startup Disk Full Fixer.
Tip 1: Remove the App Cache from Your Mac
The app cache files are necessary when you want to speed up processes. Once you complete the process, the cache files become useless. But these cache files will stay on the startup disk for a long time unless you manually delete them. When they are useless, they are junk files. To clean up your Mac startup disk, you need to remove them from the machine.
- Go to Finder > Go > Go to Folder.
- Type ~/Library/Caches.
- Go into each folder and then delete the files in it. You can also choose to only delete the files that take up the most space.
- You can repeat the above three steps for /Library/Caches to remove the App cache.
Tip 2: Empty Trash
When you delete files from your Mac, they will be moved to Trash. The files on Trash also occupy space on your Mac startup disk. As long as you are sure that you don’t need to use these files anymore, you can empty Trash to free up disk space.
To do this job, you just need to open Trash and then click the Empty button on the top-right side to remove files from your Mac. Since then, there will be more available disk space on your Mac.
Tip 3: Delete the Unnecessary Time Machine Backup Snapshots
Most people would like to use Time Machine to back up their Mac files to an external hard drive. You may think that the backup files are save to the external hard drive. But that’s not all. During the Mac data process, the local snapshots also automatically start once every 24 hours. That’s right. The snapshots are saved to your Mac, taking up disk space.
You can delete the unnecessary Time Machine backup snapshots to release space on the startup disk.
- Open Finder.
- Go to Go > Utilities.
- Double-click Terminal to open it.
- Type sudo tmutil disablelocal into Terminal, and press Enter.
Do you know how to delete Time Machine backups on your Mac computer? In this post, we will show you different cases and different methods.
Tip 4: Delete Browser Cache
Every time you visit a new web site using your web browser, some cache files will be created and saved to your Mac disk. This can help you to quickly a previous page again. But these files can also use up your disk space. So, you can delete these browser cache files to release more space on your Mac:
- Open your web browser.
- Click the History tab and then select Clear browsing data.
- Select the cache files you want to delete like Cookies, site data, Cached images and files.
- Choose how far back you want to delete
- Click the Clear browsing data button to delete the selected cache files.
Tip 5: Remove Language Packs
Most apps contain language packs (which are also known as localization files). These packs allow you to switch between languages when using the app. They are useful, but you need to admit that you only need one or two languages. The rest language packs just waste your disk space. You can choose to delete them:
- Open Applications.
- Right-click an app and then select Show Package Contents.
- Click Contents.
- Click Resources.
- Delete the language packs you don’t need to use. The pack files are ending in .Iproj.
- Repeat these steps for all other apps on your Mac.
