Free health-check script for Mac mini servers
A free diagnostic script is available for desktop Macs that stay on for serious daily use. It checks SMART data so storage problems can be spotted before a drive fails. It shows where storage is being used, including Trash, Downloads, caches, iPhone backups, , Xcode files, and anything larger than one gigabyte.
It adds together each app and its helper processes, so memory use is shown closer to the real total per app. It also looks for common reasons a Mac feels slow right now, such as Spotlight indexing, activity, or one process using too many resources. At the end, it gives a health score out of 100, with each penalty tied to a measured result.
It keeps history between runs so changes can be compared over time. On desktop Macs, it detects that there is no battery section and skips it; the tool is free, MIT licensed, and has no .

- The script is aimed at desktop Macs, not laptops, so it skips battery checks.
- SMART data is used to check whether the storage device may be unhealthy.
- It maps large storage use across Trash, Downloads, caches, backups, , and Xcode files.
- It totals each app with its helper processes to show more realistic memory use.
- It gives a 100-point health score and keeps history across runs.
