Install greyspace
A few minutes, start to finish. Every step is written out, so you can follow it without the pictures. The screens are drawn, and may look slightly different on your version of macOS (macOS 14+).
Step 1
Download greyspace
Buy greyspace, then use the Download button on the thank-you page. Any time later, enter your licence key on the download page to get it again.
Open greyspace.dmg from your Downloads folder and drag greyspace onto Applications. Then eject the disk image.
Step 2
Open it
Open greyspace from Applications.
If macOS says it can't open greyspace, that's expected for an app downloaded from its maker's site rather than the App Store. Do this once:
- Click Done on the message.
- Open System Settings › Privacy & Security, scroll down to Security and click Open Anyway next to greyspace.
- Click Open Anyway again to confirm, and enter your password or use Touch ID if asked.
Step 3
Activate your licence key
Paste the licence key from your order email and click Activate. One key works on 2 Macs. There's no free trial: until a key is activated, greyspace shows only this screen.
Step 4
Allow Full Disk Access
greyspace explains why it needs Full Disk Access: much of System Data sits in folders macOS keeps from apps. Click Open System Settings and switch greyspace on under Privacy & Security › Full Disk Access. macOS may ask for your password or Touch ID.
greyspace notices when it's allowed and moves on by itself. It reads sizes and file names, never the contents of your documents, and nothing is sent anywhere. If macOS asks you to quit and reopen greyspace, do that.
Step 5
Scan and review
The first scan measures System Data and splits it into causes, each with a size and a safety label. Open a cause to see what it is and what's in it. To fix one, pick items and click its fix button, such as Move to Trash…: a review sheet shows exactly what would be moved to the Trash, or which command would run, before anything happens. The space is free once you empty the Trash.
Protected actions, such as deleting a local snapshot or rebuilding the Spotlight index, ask for your administrator password in the standard macOS prompt. So does measuring the Spotlight index and other folders only an administrator can read: click Measure with password….
Put something back
Files greyspace removes go to the Trash. Open the Trash in the Dock, select the file and choose Put Back. greyspace's History lists every fix with its date, path and size, so you can find it.
Uninstall
Quit greyspace, then drag it from Applications to the Trash. To remove its history and growth watch too, delete ~/Library/Application Support/greyspace. You can switch off Full Disk Access for it in Privacy & Security. To move your licence to another Mac, deactivate it in greyspace's Settings first.
