As I was using my MacBook Pro today, a message on the screen appeared. It said that the startup disk is almost full. Is there something wrong with my Mac? What can I do to get rid of startup disk full on Mac?
There is no need to panic! Just follow our tips on how to clean up your full startup disk on Mac and you should be back on track. I have just the perfect solution for you.
A startup disk is actually a partition of a drive which contains a valuable operating system. This means that the hard drive of your Mac does consist of disks. Each of these disks contains the data on your Mac. These data are your operating system, applications, files, and more. Most of Mac’s products actually have just one disk, however, power users have the capability of having two or more.
A Mac that only has one hard disk has the following features:
However, if you actually have a Mac that has two hard disks, then that means that storage indicated above will be divided into two. One of them will have your operating system and the other one will serve as your storage for your files. Still, startup disk full is an urgent thing to deal with. Let's learn why is your startup disk full and how to free up your disk space to get a new Mac.
At one point or another, a Mac user will see “Your startup disk is almost full” on their screen. While this is a problem that requires prompt action, it isn’t the end of the world. You get this error because your primary disk drive is running out of space, which makes your Mac run slowly. The startup disk is the hard drive where your operating system is stored. That makes it the most essential disk on your Mac. It also contains user data such as apps and files.
Having a startup disk that is close to full poses two problems:
Ideally, 10% should be left free on your startup disk to provide enough space for your Mac to work well. Always remember that a hard disk should not go beyond 85% capacity. If this happens, then your Mac will perform slower and you will have more errors in using your Mac when you go beyond 85%.
Of course, the first thing that you should do is finding out what data is actually eating up storage on your Mac. Here is how you can locate your startup disk.
After that, your Mac will then start to show you its hard disk in an icon form. These are actually the disk/s that you can start up. The reason for this is because they carry your Mac’s operating system. If it happens that you have more than one hard disk, then go ahead and follow these steps:
After that, you will be able to see your hard disk again and they might carry names like “MainSSD” or “MainHD”. You will also be able to the operating system that is running on your Mac. If it happens that you have more than one hard disk, then your startup disk is the one that is carrying the latest version of macOS.
Now, here is how you will be able to see what are the things that are actually taking up space and make your startup disk full:
Cleaning up your Mac’s full startup disk is easier and quicker if you’re using the right tool. An excellent example is iMyMac Mac Cleaner, it helps you check and free up more disk space on the startup drive. It removes the unnecessary files that take up your disk space, including system junks, duplicate photos, mail attachments, iTunes old backups, browsers caches, apps, ect. Just with a few clicks, you will have more disk space released.
Well, you’ll find out just how much junk files you have once you download and use the software:
In order to free more space on Mac startup disk, just go back to the left-hand side of the screen and repeat steps 1 to 3. In this case, you have to select Large & Old Files, Mail Trash, Duplicate Finder, Uninstaller or other functions to remove other unnecessary files in your disk.
Did you know that every time you decide to update iTunes, it creates a backup of your iTunes library? This just gives you a whole lot of backups that you don’t even need. That’s why this is a good place to start to clear up your startup disk. After all, you’ll only need one backup. Here’s how to look for your backups and get rid of them:
If you have an iPhone or iPad and you update them using iTunes, you likely have a ton of backups in your Mac. Follow the steps below to get rid of them:
Aside from creating backups of your iDevice’s files, iTunes also downloads updates for your device’s apps. Once your apps are updated, the updates no longer serve any purpose. They simply stay on your Mac and waste space. Here’s how to look for them and remove them:
Cache files help your Mac run applications faster. However, they accumulate over time as programs generate temporary files. They remain on your Mac and eat up disk space if you don’t delete them yourself. When you get rid of cache files, the priority must be with removing the largest files.
Do not delete everything. Moreover, we recommend deleting the files inside the folder instead of deleting the entire folder:
Your apps may come with language packs that allow you to change the language in the app. It’s a great option, but let’s admit it. We only use our app in one language. We can get away without the rest. Here’s how to clean them up:
Look for files ending in .lproj. These are the language packs. Select those that you are not going to use and delete them. Repeat the steps for other apps.
Many users have numerous apps that they have never launched. In such case, there is no better way to free up your full startup disk than to remove old and unused apps.
We suggest using iMyMac Mac Cleaner's Uninstaller for this purpose. Dragging an app straight to Trash can leave behind hidden files such as app logs. However, this tool successfully uninstalls the app and deletes associated files along with it.
Every time you visit a new page on your internet browser, it generates cache to make it load faster on your future visits. Doing this on every page, though, will lead to a growing browser junk. How you remove browser cache that may differ for different browsers? Visit the support page of the developer for more details.
Your Downloads folder is a goldmine of unnecessary files. There is also a big chance that you don’t even remember downloading a couple of them. Get rid of everything you don’t need, and try to organize your files. You’ll thank yourself for that in the future. Check out your folders for photos, music, and videos as well.
There are files that we don’t use that often but we need to keep. The best option for these is to compress and turn them into smaller files. It’s just easy to do that. Ctrl + Click the file that you want to compress and hit Compress. This is recommended for huge files like movies and videos.
After deleting all those junk, they are just sitting in the Trash. Now it’s time to get rid of them – for good. Click on the Empty button, and this should free up considerable space in your startup disk.
Now that we have already discussed everything about your startup disk full, then it is time for you to take some actions for you to prevent it from getting full. Remember that a full startup disk will cause your Mac to get slow. You should regularly clean up your Mac to ensure that it is performing optimally and you have sufficient space for your files. Don’t worry, iMyMac Mac Cleaner will make it a breeze!
