Apple developed the HFS+ file system, but it took decades for the company to update it. In 2017, Apple finally released an updated version called APFS with improvements to encryption, space allocation, and file integrity.

While the new file system seemed perfect, some end users have run into unexpected issues and incompatibilities. One of which is the error 49153.

What is Error 49153?

The error 49153 is an error that surfaces after a shrinking partition failure. Users have reportedly seen the error after performing a partition shrink using Disk Utility.

Experts suggest that one of the primary causes of the error 49153 are the locally stored snapshots of Time Machine backups on the system partition, even though other possible factors could include malware entities and system junk.

Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.
