Mac Glance/

A little visibility. Only when you need it.

See drive space, memory, CPU, network traffic, and where your files use storage. Open it, look, and close it. Nothing is uploaded. There is no account, and nothing runs in the background after you leave.

Older Macs are welcome. One download is enough.

Mac Glance splash: on your Mac, local only. A little visibility. Only when you need it.

Mac Glance live overview showing free drive space, memory in use, CPU, and disk activity. — Live readings while the page is open. Storage scans stay optional.

A glance, not a watcher

Mac Glance answers ordinary questions: how much disk is free, what is using memory, whether the processor is busy, and which files are taking space. It does that only while you are looking.

Stays on this Mac

The page is served to your own computer. There is no sign-in, no remote font, no analytics, and no cloud copy of your files. A scan of your home folder, if you ask for one, stays beside the app on disk.

Made to be left alone

It does not install a login item. Hidden tabs pause live readings. Quit the monitor, or close the tab; after a short wait with no page open, the local process exits on its own.

Get it on your Mac

Download MacGlance.dmg. It appears in Downloads, like any other file you save.
Double-click MacGlance.dmg. A small window opens with a few items in it. That window is the Mac Glance disk.
In that window, double-click the item named Open Mac Glance — those three words, in that order. Leave the Mac Glance icon alone for this first open.
If your Mac asks whether you are sure, choose Open. A browser window should appear.

There are two similar names on purpose. Open Mac Glance is the starter. The Mac Glance icon is the app itself. If you click the app icon first, your Mac may say it is damaged. That is not true. Close the warning, go back to the window from the download, and double-click Open Mac Glance.

Drag the Mac Glance icon to Applications if you want to keep it. After it has opened once, you can optionally bookmark computer-dashboard:// for one-click return visits.

What you will see

Drive space — room left on the disk that holds your home folder.
Memory and CPU — how hard the Mac is working right now.
Network — traffic by program or by interface.
Storage snapshot — largest folders, files, and file types in your home folder, after you choose to scan. You can cancel. Mac Glance reads sizes and locations, not file contents.

Click a number for a short explanation. Question marks open help. Looking around never starts a scan on its own.

Privacy, in plain terms

It listens only on this Mac (127.0.0.1).
It does not upload your data.
It does not run when you are not using it.
Delete the Mac Glance folder inside Application Support to remove a saved storage snapshot.
