Here are the instructions to install RMySQL on OS X "Yosemite": Download and install the MySQL community server for OS X . You will need a free Oracle account to complete the download. At the time of this blog post, I installed mysql-5.6.22-osx10.9-x86_64 via the DMG archive. By default MySQL will be installed in /usr/local/mysql-5.6.22-osx10.8-x86_64 (if you use a different version, look for an equivalently named directory under /usr/local). Download sources for the RMySQL package from CRAN . At the time of this blog post, I downloaded RMySQL_0.9-3.tar.gz . Open a Terminal window and run: export DYLD_LIBRARY_PATH=/usr/local/mysql-5.6.22-osx10.8-x86_64/lib:$DYLD_LIBRARY_PATH You may want to consider adding this line to .bashrc as well. In the same terminal window compile and install RMySQL using this command (in a single line): R CMD INSTALL --configure-args="--with-mysql-dir=/usr/local/mysql-5.6.22-osx10.8-x86_64 --with-mysql-inc=/usr/local/mysql-5.6.22-osx10.8...

Oracle's JDK 7 installer for the Mac somehow thinks that OS X Yosemite's 10.10 version number is an unsupported version. There's a simple trick to fool the installer by giving it a version number that it expects. Open a Terminal window and edit the file /System/Library/CoreServices/SystemVersion.plist as root/Administrator. If you are familiar with vi , simply run sudo vi /System/Library/CoreServices/SystemVersion.plist . The file should look something like this: <?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>ProductBuildVersion</key>      <string>14A329f</string>      <key>ProductCopyright</key>      <string>1983-2014 Apple Inc.</string>      ...
