OSX SSD Terminal Tweaks + Other Tweaks Applied

[DNAZero]

Dear All,

Just to post up a few terminal tweaks that I have applied to my system after I installed my SSD. These tweaks work with both 10.5 and 10.6.

Disable waking up when LID opens
sudo pmset lidwake 0

No hibernate
sudo pmset -a hibernatemode 0

Disabling Sudden Motion Sensor
sudo pmset -a sms 0

Verify applied tweaks
pmset -g

Other tweaks:

Screen capture save format
defaults write com.apple.screencapture type jpg

Screen capture save location
defaults write com.apple.screencapture location [path]

Mac login window display System Time
sudo defaults write /Library/Preferences/com.apple.loginwindow AdminHostInfo Time

Safari single window mode
defaults write com.apple.Safari TargetedClicksCreateTabs -bool true

Add a “Recent files” stack to Dock
defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'

Make Dock app icons spring-loaded
defaults write com.apple.dock enable-spring-load-actions-on-all-items -boolean YES

Snow Leopard Stack Highlight
defaults write com.apple.dock mouse-over-hilite-stack -boolean YES

Reload Dock
killall Dock

Just to share the tweaks that I have applied so far. Free to share yours if you discover any good ones. Thank you : )

There's a sticky thread above for this - and you should look into the mount option to kill last accessed stamp.

You mean noatime? But those tweaks are mainly for Linux.

How do you enable noatime for OS X?

[sascha h-k]

please see "osX tweaks" .. about page 4 or 5.

Yes - noatime - and my apologies, the thread I was referring to isn't sticky, but floating free. At the moment it's toward the top.

Does notime work in 10.6 ?

To everyone here is a step by step on how to do it. Even though it is not hard but the instruction was not clear. For anyone who do not understand, maybe what I am rewriting here might help you.

To enable noatime:

1. Open up Applications>Utilities>Terminal.app
2. At command prompt type sudo bash then press Enter.
3. It will ask you to input your user password make sure you have the admin rights.
4. At the bash prompt type vi /etc/rc.local then press Enter.
5. Then you will be in the rc.local editor screen.
6. Press I (in order to start editing)
7. Input the following code or you can basically cut and paste to it from here

#!/bin/sh
mount -vuw -o noatime /

8. Press ESC to stop editing and type : w q then press Enter to exit the editor.
9. Back to the prompt type chmod 775 /etc/rc.local then press Enter
10. Type Exit and press Enter to exit.


PS: This do not work on 10.6, and the method below works on both 10.5 and 10.6.

noatime settings for both 10.5 and 10.6.

1. Open up Application>TextEdit.app
2. Type in or Paste the following code into the editor.

<?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.my.noatime</string>
<key>ProgramArguments</key>
<array>
<string>mount</string>
<string>-vuwo</string>
<string>noatime</string>
<string>/</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>

3. Save it as com.noatime.plist or any name you would like to call it.
4. Then copy the file to /Library/LaunchDaemons/
5. Set proper ownership in order for LaunchDaemons to run properly.
6. Open up Applications>Utilities>Terminal.app
7. At prompt type sudo chown root:wheel /Library/LaunchDaemons/com.noatime.plist
8. Make sure you Delete the /etc/rc.local file if one. Skip step 9 and restart if you do not have one.
9. At prompt type sudo rm /etc/rc.local
10. Restart your system.

To verify open up Terminal.app
At prompt type mount

You should see noatime in there. And here is mine.
