Perform these changes at own risk! You may wreck your system, so make sure to have a current backup!
I just upgraded my mid 2010 15" Macbook Pro with an OCZ Vertex 2 SSD and 8 GB of RAM. Browsing the net for hints how to optimize the system when using an SSD, I applied the following changes to my system:
pmset -a sms 0. You can even store this in
/etc/rc.localto ensure it is not changed.
<?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.nullvision.noatime</string> <key>ProgramArguments</key> <array> <string>mount</string> <string>-vuwo</string> <string>noatime</string> <string>/</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist>
followed by a
sudo chown root:wheel /Library/LaunchDaemons/com.nullvision.noatime.plist
There are also some things that I haven't tried out yet, but that might also speed up things or that might be beneficial to the lifetime of your SSD:
$ sudo pmset -a hibernatemode 0 $ sudo rm /var/vm/sleepimage
Be aware: this may result in data loss if running out of power during sleep as nothing is written persistently to disk.
