We understand that you're experiencing an issue with Other storage on your Mac, and we want to help.
You can find some great information about how to manage storage on your Mac here: Free up storage space on your Mac
"Other measurements, including measurements in other tools, might calculate storage space differently or show storage categories such as Other, Purgeable, Free, Other Volumes, Not Mounted, VM, Recovery, or System Data. Don't rely on those measurements to understand how much space is available for your data, or how to make more space available."
For more details on used and available storage space on your Mac, please check out this link: See used and available storage space on your Mac
Thanks!
