The macOS might fail to show folder sizes on Finder for various reasons.

One common cause is the intricacies of how macOS calculates folder sizes. The Finder typically provides an estimate rather than real-time calculations, and this process can be delayed or interrupted, especially with large or deeply nested folders.

Additionally, issues related to Spotlight indexing, which is responsible for cataloging file information, may hinder the accurate display of folder sizes. Incorrect disk permissions or corruption within the file system can also contribute to this problem.

In some cases, Finder glitches or bugs might be responsible, necessitating a system restart or other troubleshooting steps.

Utilizing third-party applications for more detailed disk space analysis can offer a workaround. Addressing the issue may involve rebuilding Spotlight indexes, checking and repairing disk permissions, and using alternative tools to obtain precise folder size information.
