Mac OS 7.5.4 or System 7.5.4 was a version of the Mac OS which reached Golden Master status and was slated to ship as an unified upgrade. However, just hours before it was slated to be seeded, distribution was halted.

Mac OS 7.5.4 was released by Apple Inc. to a limited distribution, prior to an anticipated general release. Shortly after this limited distribution, it was discovered that some components had not been included in the installer..

Apple explains that Mac OS 7.5.4 was declared finished, and that distribution to seed sites actually had been initiated. However, an installer packaging issue was discovered, leading to the halting of distribution. Rather than having to struggle with two versions of Mac OS 7.5.4 (which was the case with Mac OS 7.5.2), Apple decided against the resulting confusion and revised the product version number to 7.5.5.
