- What is arcmac?
- arcmac is a collection of three Mac utilities: Rings, a disk space analyzer; Pulse, a menu bar system monitor; and Clips, a clipboard history manager. Each one is downloaded as a DMG file from arcmac.app.
- How do I see what is taking up space on my Mac?
- Rings scans a disk or a folder and draws it as a sunburst map, where the widest arcs are the largest folders. Click an arc to open that folder and find the files using the most storage.
- How do I check CPU and memory usage from the Mac menu bar?
- Pulse adds a readout to the menu bar and opens a compact panel showing processor load, memory, storage, network activity and battery.
- How do I keep a clipboard history on a Mac?
- Clips saves what you copy and lists it in the menu bar, newest first. Search the list to find an earlier item and paste it again.
- How can I check that an arcmac app is safe to install?
- Each app page lists the security checks for that build: Developer ID signature, Apple notarization, hardened runtime and a SHA-256 checksum. Every check comes with the Terminal command to repeat it on your own Mac.
- How do I install a Mac app from a DMG file?
- Open the DMG from your Downloads folder, drag the app into the Applications folder, then open it from Applications. The first time, macOS asks you to confirm that you want to open an app downloaded from the internet.
