Well, your startup disk is the partition on which your Mac operating system runs. It has a set amount of space (say, 500GB) that you can use to store applications and files. You can't get rid of that disk because it's what your Mac uses to function. Click the Startup Disk icon in System Preferences, or choose View Startup Disk.

That's why we decide to write this post, offering a number of better ways to reclaim more space when MacBook startup disk is full. The best part? We'll make it as detailed as possible so you won't feel lost.
Let's get started, but first…
What's Filling up My MacBook Startup Disk?
So what exactly is your startup disk? Well, your startup disk is the partition on which your Mac operating system runs. It has a set amount of space (say, 500GB) that you can use to store applications and files. You can't get rid of that disk because it's what your Mac uses to function. However, as time goes on the files and apps you add to the MacBook drive will begin to accumulate and limit the space remaining on that disk.
Note: most MacBook users have just one disk named 'Macintosh HD' by default, but power users may have two or more.
You'll get a message from Apple system when your disk is almost full, and if it fills all the way up you won't be able to download new files, open attachments, or install new programs. How to make a file on macbook. An overfilled startup disk will also cause your MacBook to run slower since it won't be able to use RAM as effectively. This means keeping your disk clean is extremely important for daily operations.
To check what's taking up space on your mac, you can choose 'Manage' on the startup disk warning notification. If you're ahead of the curve and trying to clean up your Mac before being warned, you can access the management screen by going to About This Mac from the Apple menu (top left of your screen), and then choosing Storage.
You can also use CleanMyMac (via the Quick Menu shown below) to get a quick overview of how much storage space are taken. By the way, the app does more than just that. You can easily use it to clean up gigabytes of system junk and unnecessary files in minutes.
Regardless of which methods you use, these tools will help you see what's taking up the most space and guide you towards where to start trimming down.
How Do I Free up More Space on My MacBook?
Now that you know what's stealing your storage, how can you fix the problem? Aside from the obvious solutions like clearing the trash and downloads folder, there a few different methods you can use.
Tip: Before using any of these methods, backup important files! Time Machine is the built-in app you could use and it's free. You may also use advanced backup software Get Backup Pro, which offers more powerful and convenient backup options.
1. Erase Duplicate or Similar Files
These days we all are used to back up phone/camera photos to our computer, and believe it or not, identical or similar files can quickly add up and occupy lots of space. They can be duplicate documents, images taken twice (or more times), redundant backups, and several other formats. The tricky part is those files are usually not easy to be found.
Fortunately, you can use a handy app like Gemini to quickly locate them.
Using the app, you can choose folders to scan and find these unneeded duplicates. Gemini then separates exact duplicates from similar files so you know exactly what you're looking at, and you'll be prompted before deleting anything. It can help you reclaim a lot of valuable disk space in just a few minutes.
2. Offload Important but Infrequently Used Files
How often do you watch the movies you've downloaded to your computer? Do your old photos need to be within reach at all times or only upon occasion? If you're someone who keeps archives of documents, images, movies, programs, or other files but only occasionally reference them you might benefit from transferring them to an external drive.
Then start copying files from your MacBook to the external HDD. If you're copying projects such as unfinished movies or designs, make sure you copy all assets as well or the file will not be able to load properly.
3. Beware of Mac System Files
Depending on the macOS you're using, you might notice that 'System Storage' or 'Other Storage' keeps increasing and as a result, taking too much disk space. The worst part? You can't analyze what's stored inside as this option is greyed out by macOS by default.
Thankfully, you can use CleanMyMac X to get an 'insider' look and clean those unneeded system files. Just download the app and install it on your Mac. Open it, click on Space Lens, run quick scan of your Macintosh HD, then under 'System' folder, you'll be able to see all the details.
4. Sign up for a Better Cloud Storage Program
You may have noticed that Mac's storage manage panel prompts you to consider iCloud as a way to clear space (see the screenshot below). While we aren't a huge fan of Apple's subscription cloud storage program, there are plenty of alternatives available.
Two of the most popular are Google Drive and Dropbox.
Google drive will give you 15GB of free storage space, and the companion program Google Photos offers unlimited image and video storage at 16MP or 1080p and less. If you still don't have enough space, you can upgrade your Google Drive to 100GB for just $2/month or a terabyte for $9.99/month.
Dropbox offers a basic account for free with 2GB of space, but upgrading to Dropbox Plus will get you a terabyte of uploads for $9.99/month. According to 9to5mac, Dropbox stands out for its file-sync speed and reliability as he put:
'For me, the crucial benefit of Dropbox is speed and reliability. I've tried all the main services over the years, and Dropbox has always been 100% reliable and has consistently synced within seconds.'
Both programs offer an automatic import function as well to help cut down on your work.
5. Deep Clean Your MacBook Drive
If storage space seems to be a recurring problem, you will benefit from cleaning out system junk and useless files to stay on top of any storage issues. Again, CleanMyMac is the best solution to handle this. It's an app that provides you insightful information on what's taking away your storage.
You can use the app to scan unnecessary files such as temporary documents, attachments, and iTunes/iMovie junk that usually require extensive searching to find buried in your Mac's library. After the scan, it then offers a number of suggested actions you can take to reclaim more space.
6. Manually Delete Old Large Files & Apps
If you're looking for a quick and short-term fix, manually clearing out those old large files will help you get a few extra gigabytes of space without sacrificing a great deal of time.
First, open Finder and navigate to 'All My Files' from the sidebar. Make sure your files are in list view (the icon that looks like 4 stacked lines should be dark grey) and then choose 'Size' from the header.
If you're on an older macOS, you'll need to click the settings gear in Finder and select ARRANGE BY > SIZE. This will produce a slightly different layout which groups your files by category (100MB – 10GB, 1MB – 100 MB, etc). You can find the size of each file by right-clicking and choosing 'Get Info'.
Once you know which files are largest, you can start removing those you no longer need and clearing space as efficiently as possible. Some common space hogs include videos, old DMGs, creative applications, and large audio files.
A quicker way to spot out old big files on your Mac is to run CleanMyMac X (again) and navigate through the Large & Old Files feature as it will sort all those items based on file size.
