~/Library/Caches/com.microsoft.edgemac stores temporary Microsoft Edge browser data used to speed up loading, browsing, and other routine tasks on Mac.
What is com.microsoft.edgemac?
Microsoft Edge is a web browser for macOS and other platforms that helps users browse websites, sign in to accounts, sync browsing data, and use modern web apps and extensions. The folder at ~/Library/Caches/com.microsoft.edgemac contains temporary cache data created by Edge during normal use. This data can include files that help pages load faster, store reusable web content, and support smoother day-to-day browsing sessions. Cache folders are common for browsers because they reduce repeated downloads and improve responsiveness. Removing this folder does not uninstall Microsoft Edge, but the browser may recreate it automatically and some sites may load more slowly until the cache is rebuilt.

Safety overview
Status: Mostly safe
This is a user cache folder associated with Microsoft Edge, not a core macOS system component. Deleting cache data is generally low risk, but it can sign you out of some sites, remove temporary website data, and cause slower page loads until Edge rebuilds the cache. If Microsoft Edge is open while you remove the folder, some files may be locked or recreated immediately.
Recommendation: Keep this folder if you use Microsoft Edge regularly and want to preserve temporary browsing data for faster performance. You can remove it when you need to free space or troubleshoot browser problems, then reopen Edge and let it create fresh cache files. If you no longer use Microsoft Edge, removing this cache folder is a reasonable cleanup step.
