2, 用写字板新建文本文档如：新建文本文档.txt，然后后将如下拷贝到文档内，
然后将“新建文本文档.txt”改名字为 com.apple.virtualMemory.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>KeepAlive</key>
<true/>
<key>Label</key>
<string>com.apple.virtualMemory</string>
<key>OnDemand</key>
<false/>
<key>ProgramArguments</key>
<array>
<string>/sbin/dynamic_pager</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>
