Startup Disk is Full: What to Do in The Situation


Published On: , by MacSoftAdmin

If it happens to you, do not panic. Fortunately, you, most likely, will fix this issue quite simply. Years of constant usage have high chances to make Mac disk full and overflowed with random bits of data. But, what to do if your Mac startup disk is full? Read on to find out how to make a free space when it seems that there is any.

If your Mac startup disk is full, you can also use some cleaning apps like MacFly Pro or any other app.

In case you have not been in such situation yet, you will be there one day. Imagine that you are travelling along with your own computer, import photos from the vacation from your iPhone or upload a new album of your beloved group, and everything would seem alright.

The Alert when Startup Disk is Almost Full

But, one day your Mac startup disk is full, and what to do now?

So you see it. This window that came out from nowhere to tell you that you have no free space. Your Mac is not friendly anymore. It is claustrophobic and dark. Your mac drive is full, and you can be just an observer of how your computer has reached its own limits.

Step 1. Clean Up Your Trash

This error that appeared on your screen is considered a 911 call. Your computer yells for support,  and you need quick wins in order to return it from the dead. The fastest and most unpretentious method to make your drive drop a few gigabytes is to empty the trash. Lazy users, who rarely empty their personal trash, have every chance to own gigs of unnecessary files that make Mac drive full.

Erasing the Items from the Trash

If it describes you, go to the Finder, press Command-Shift-Delete and do not look back. Now, do it every day, or at least once a week.

Step 2. Check Up the Movies Folder

The first step was intended for a quick fix, but now it’s time to use big guns. You need to release 10, 20, or even hundreds of GB of data as soon as possible. In case you need a tremendous impact, the best place to start is the “Movies” folder.

Go to the Users/YourUserName section and click the “Movies” folder. Now press Command-I and look at the upper right corner of the window in order to see the size of the space this folder takes up.

When I did it by myself, I saw that it actually feeds nearly 30 GB of data or even more. It, of course, is not a small piece of space, so do not be surprised. Video content is a beast when it comes to space storage, and it fills up even the largest disks in no time.

In fact, almost all applications reported to this folder are needless applications and may be not necessary for you. It happens that some screencasts or iMovie projects roll around in there and take up some space. However, be careful when deleting the data.

Step 3. Clean Up the Desktop and Downloads Folder

Trash is not considered to be a single space on your computer, which, as a rule, works to collect random data bits. For some users, the Desktop and Downloads folders are considered gold mines of files that were added and have never been organized. It is also one of the reasons why hard disk is full on Mac.

This is a good practice to think about these spaces as transitional. If something has been there for longer than a week, it’s time to either destroy it or put it somewhere more intentional, for example, the folder “Documents” (or your external drive).

It is important to sort your files by Date Modified or Date Created, etc. That will help monitor for how long you haven’t used this or that file and delete in case it’s unnecessary for you.

Step 4. Clean Up Big Cache Files

Caches are short-term files created to speed up specific tasks. The problem is that the cache files actually have the potential to take a lot of space with the flow of time. There are a lot of third-party applications like MacFly Pro that can help you clean up all sorts of caches in your system, but it’s not something that is actually hard for you. In addition to this, deleting cache files will help avoid probable issues with Mac OS security.

Kill the Other Big Media Files

Music is, once again, a tremendous animal when it comes to storage. Just repeat the above-mentioned process with your own music folder. Go to Home/Music/iTunes /iTunes Music and see if you can find old albums that you’ve never listen to.

Scanning the Hard Drive

The above-mentioned folders were one of the main places to eat up your storage. In any case, the manual check is not always convenient and can be rather problematic. Third-party apps can pull in some help and scan the hard drive to find out the worst areas of your Mac. To my mind, MacFly Pro is a user-friendly and fast application that may save up the great amount of time for you.
