Over a period of time, your Mac will start building up files which will reduce the amount of available free space. These files not only reduce the storage capacity, but also interfere with the performance. Here are some tips to free up disk space in Sierra Mac OS.
Clean Cache Files
The Mac OS and Apps installed inside create lot of junk files, out of which most are cache files that are needed to speed up performance. The problem is when there is too much cache, rather than speeding up it slows down computer performance. Also too much cache eats up available free space in your computer.
Clean Files inside the Trash
When a file is deleted, it goes to trash. Over a period of time, there might be too many trash files that eats up disk space. Most Cache Cleaning Apps does have an option to clean trash automatically. In case if it doesn’t have the option, you can also delete it manually.
To delete these files, press Ctrl button + click trash icon and then delete it.
Also go to downloads folder and delete the files that are no more needed.
Clean bigger files
You might have movies, media files or downloaded files which may not be useful anymore. The problem is you may not notice the existence of this file inside your Mac. In such situations, check for the biggest files in your Mac. Since these files are limited in number, you can go through it one by one and delete the unwanted file.
Use OmniDiskSweeper to find big files that use most disk space. Confirm if the big file is of any use in the future. If you need it, transfer it to an external drive for later use. Remove if you don’t need it.
Remove unwanted Apps
If you have too many Apps, remove the ones that are not needed. Also remove old Apps which are not compatible or updated for use with the latest Mac OS Sierra.
Remove duplicate files
Duplicate files are very common especially with media and picture files. Too many of these files can take up lot of space in your Mac.
Install and run an App like dupeGuru. Set the App to look for Standard, Music or Picture. Select Home as the place to look for as it will scan the entire drives.
Clean your Desktop
Desktop is a place where most users save their files for easy access. At least some of these files may not be needed anymore. Remove those files. It feels good to have a clutter-free desktop.
