I searched and found several steps to remove the redundant files. Then I found in /private/var/db/receipts there are many config like files, Anyone know the purpose if this directory?

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.

  • Yes, it's nothing to do with MySQL. I will remove this in the question. I found even after I removing the software on my mac, the related plist and "receipts" files still remains here. Is it safe to remove them? @JBis – Yiliang Tang Jun 25 '18 at 2:37
  • @YiliangTang Well you still have a receipt after using the item you buy. It should be safe to remove them, especially since you removed the software associated with them. To be sure I would just but them in trash. Use your comp for a couple of days and if there are no issues then you can empty trash. But I don't really think removal is necessary. Lastly, if this answer solved your problem please mark it as answers and upvote so other users with similar/same issues will be able to find it easier. Thanks! – JBis Jun 25 '18 at 2:46
