How to Fix the Startup Disk Full Error on Your Mac

Your computer needs disk space for file storage and to perform many behind-the-scenes operating system functions such as memory management. You do not really have a lot of options in how you address a startup disk that is almost full. Basically, your only recourse is to free up disk space to give your machine enough available storage to perform optimally.

Failure to free up space will lead to worse performance and an eventual inability to start your Mac. You have to delete some files to increase the amount of free space available for your system. There really is no way around this fact. You do, however, have some choices in how you can go about freeing up storage space. You can use the manual method, which we will discuss shortly. A better option may be to avail yourself of some free third-party software such as Disk Drill to help speed up the process of identifying and eliminating the extraneous files and apps, which will allow your machine to operate at peak efficiency.

Combing through all of the various locations on your Mac which may be the home of files or apps that you can delete can be a very time-consuming process. A much faster way to perform the task of reducing the amount of storage your startup disk is using is to use the functionality built into Disk Drill Software. Disk Drill is a comprehensive data recovery application that has the additional ability to scan your disk and create a map of your storage. You can download the application for free and use it to get your disk storage under control.

The disk map generated by the tool lets you filter the results to address specific types of files or files that take up a certain minimum amount of space. The tool lets you identify duplicate files which can be deleted. Disk Drill also prevents you from deleting files that your operating system needs in order to function properly.

You can also use manual means to clean up your startup disk. It will take some more time, and does present the possibility that you can inadvertently delete a file that your system requires in order to operate.
