How I reclaimed the free spaces of macOS Mojave

Recently, I upgraded main SSD drive from 500GB to 1TB. Soon, something is consuming the free space of the SSD.

I googled and tried everything I can, but none of them changed the situation.

But, finally I got the reason for this.

Read this article:

I do backup everyday using CCC(Carbon Copy Cloner). It has a feature similar Time Machine. So, everytime I make backup, it create a snapshot by default.

But I didn’t know CCC has such a feature.

I deleted some of the old snapshots, the free space increased as it was.

You can set the minimum free space ( 30GB is the default ). So, set it like 100GB, you will be happy!



それはCarbon Copy Cloner(CCC)のSnapshot機能だったのだ。CCCはデフォルトでSnapshotを保存する機能がオンになっているらしく、知らない間にそれが空き容量を食いつぶしていた。
