How I Discovered What Was Eating My Mac’s Storage

I ran into this problem: my 2TB SSD kept filling up at an impossible rate. No matter how much I deleted, the free space would vanish again. After clearing out every obvious file and folder I could find, I finally decided it was time to dig deeper.

I started poking around in Activity Monitor, and in the Network tab I noticed something suspicious — Data received: 22.93 GB. That seemed unusually high. Based on a few online suggestions, I downloaded DaisyDisk to get a clearer picture of what was going on.

Seconds after scanning, I found the culprit: the Overcast podcast app.

It had automatically downloaded every podcast I was subscribed to, quietly consuming 912.7 GB of space. I immediately deleted the app and the Overcast Container folder, reclaiming nearly a terabyte.

I like to occasionally use Overcast on desktop, so I’ll reinstall it — but next time, I’ll switch the default download option from automatic to manual. Definitely user error on my part, but wow. A startup alert in the app about massive disk usage would’ve been appreciated.
