# Windows 11's Weather app uses 5x the RAM of macOS Weather, because Microsoft has forgotten how to make native apps

## Executive Summary
Reports indicate a significant discrepancy in memory usage between the Windows 11 and macOS Weather applications.

## Intelligence Brief
According to the coverage, the Weather app integrated into Windows 11 utilizes five times the amount of RAM as the equivalent Weather application found on macOS. This disparity in resource consumption has led to claims that Microsoft has lost the ability to develop native applications for its own platform, suggesting a decline in the efficiency of its software engineering compared to its competitor. The coverage provided by Windows Latest emphasizes the specific multiplier of memory usage, explicitly stating that the Windows 11 version requires 5x the RAM of the macOS version. The outlet frames this technical observation as a broader symptom of Microsoft's current approach to app development.


By focusing on the resource drain of a relatively simple utility like a weather app, the report brings attention to the overhead costs associated with running modern Windows 11 system applications relative to Apple's software ecosystem. To understand why this trend is surfacing now, it is necessary to look at the ongoing debate regarding native app performance. The context provided by the report suggests that the high RAM usage is a direct result of Microsoft forgetting how to create native apps. In software development, native apps are typically expected to be more efficient because they are built specifically for the hardware and operating system they run on, whereas non-native or wrapped applications often consume more memory to maintain functionality.


Future developments to watch will involve whether Microsoft addresses these efficiency concerns or provides a technical explanation for the resource usage. Based on the stated facts, the primary point of interest is whether the Windows 11 Weather app will receive an update to reduce its memory footprint. Observers will likely monitor for further comparisons between Windows 11 and macOS system apps to determine if this 5x RAM discrepancy is an isolated incident or a widespread pattern across the Microsoft software suite.
