PearSilicone PearSilicone

First launch

The first time you open the download, macOS may refuse it with a message like:

“Apple could not verify PearSilicone.dmg is free of malware…”

Nothing is wrong. The download isn’t notarized by Apple, so Gatekeeper stops it until you allow it. You only need to do this once.

Clear it in one line

Section titled “Clear it in one line”

If you downloaded the image in a browser, it carries a quarantine flag. Remove it:

Terminal window
xattr -dr com.apple.quarantine ~/Downloads/PearSilicone.dmg
open ~/Downloads/PearSilicone.dmg

Then drag PearSilicone into /Applications. If macOS still complains about the installed app, do the same for it:

Terminal window
xattr -dr com.apple.quarantine /Applications/PearSilicone.app

Or allow it from System Settings

Section titled “Or allow it from System Settings”

Click Done on the warning, then open System Settings → Privacy & Security. In the Security section, choose Open Anyway next to the blocked app.
