I just got a SSD off craigslist yesterday and since then, in an effort to tweak everything I can about it, I've been trying to enable noatime, but to no avail. Here is what I have - a .plist file in Library/LaunchDaemons called com.noatime.root.plist within that file there is the following code - <?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>Label</key> <string>com.noatime.root</string> <key>ProgramArguments</key> <array>/Library/LaunchDaemons/com.noatime.root.plist <string>mount</string> <string>-uwo</string> <string>noatime</string> <string>/</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> And as some sites suggested I assigned read and write privileges for everyone on this file and ran the following in terminal - sudo chown root:wheel /Library/LaunchDaemons/com.noatime.root.plist after restarting, when I submit the command: mount , I receive the following /dev/disk0s2 on / (hfs, local, journaled) devfs on /dev (devfs, local, nobrowse) map -hosts on /net (autofs, nosuid, automounted, nobrowse) map auto_home on /home (autofs, automounted, nobrowse) I am running this SSD on a 13" MBP 2011. It is the sole drive with OSX version 10.6.8, fully updated. The SSD is an OCZ Agility 3. I hope someone can help as its incredibly frustrating. Thanks!
