What's the purpose of directory /private/var/db/receipts?
Files in /private/var/db/receipts
are...well...receipts for packages/apps you have installed on your Mac. They list what was installed and when. The Plists also include version information. For example heres an example of my plist for Xcode (com.apple.pkg.Xcode.plist
):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>InstallDate</key>
<date>2018-06-05T18:36:40Z</date>
<key>InstallPrefixPath</key>
<string>/</string>
<key>InstallProcessName</key>
<string>storedownloadd</string>
<key>PackageFileName</key>
<string>Xcode.pkg</string>
<key>PackageIdentifier</key>
<string>com.apple.pkg.Xcode</string>
<key>PackageVersion</key>
<string>9.4.0.0.1.1526532315</string>
</dict>
</plist>
I don't think it has anything to do with MySQL.
