Mac OS X has fairly good memory management but it’s not perfect, and sometimes RAM can be held unnecessarily in the “inactive” state despite the contents no longer being needed. If you’ve been participating in memory heavy activities or you just need to free up some available RAM you can actually force Mac OS X to clear out inactive memory.

• Launch Terminal, found in /Applications/Utilities/ and enter the following command

purge

• Give OS X a minute or two to complete the process

Open Activity Monitor to see the before and after results yourself, you’ll find dramatic changes at the “Free”, “Used”, and “Inactive” meters under System Memory.

The purge command forces disk and memory caches to be emptied, offering a ‘cold disk buffer cache’ which is similar to the state of the operating system after a reboot. Of course, the benefit of using purge rather than rebooting is that you don’t have to restart the machine and you can maintain currently active applications while still freeing up memory.

This is not necessary for most Mac users, but power users and those with heavy memory demands will undoubtedly find this command helpful in the future. If you feel like you are frequently hitting a memory ceiling learn how to check if your Mac needs a RAM upgrade and consider upgrading, it can dramatically improve overall system performance.

Note: You may need to have XCode & Developer Tools installed in order to use the purge command, that can be downloaded for free from the Mac App Store.

Or download Purge from here

• Launch Terminal (found in /Applications/Utilities/) and enter the following commands:

defaults read /Applications/Safari.app/Contents/Info LSEnvironment

• If you see a message like “The domain/default pair of (/Applications/Safari.app/Contents/Info, LSEnvironment) does not exist” proceed to the next defaults write command:

defaults read ~/.MacOSX/environment DYLD_INSERT_LIBRARIES

• If you see a message similar to “The domain/default pair of (/Users/joe/.MacOSX/environment, DYLD_INSERT_LIBRARIES) does not exist” then the Mac is NOT infected.

What if you see something different in the Terminal? If the defaults read commands show actual values, you may have the trojan though this does seem to be very rare. In the event you run into a Mac with the problem follow the guide on f-secure to remove the Flashback trojan, it’s just a matter of copying and pasting a few commands into the Terminal.

vm_stat will spit out a generic overview of virtual memory usage, looking something like this:
$ vm_stat
Mach Virtual Memory Statistics: (page size of 4096 bytes)
Pages free: 5231.
Pages active: 130041.
Pages inactive: 73169.
Pages wired down: 53703.
"Translation faults": 84039105.
Pages copy-on-write: 7089068.
Pages zero filled: 32672437.
Pages reactivated: 432070.
Pageins: 62166.
Pageouts: 63545.
Object cache: 1445817 hits of 1470191 lookups (98% hit rate)

If you want a continual update of your virtual memory usage, try adding a numeric value after the vm_stat command, indicating the amount of seconds that pass before refreshing the data. For example:
vm_stat 3

Booting Mac OS X is attractive and all, but some users would prefer to see what’s going on behind the scenes. Verbose mode shows you what is really happening during system startup, and is great for troubleshooting. Typically if you wanted to boot in verbose mode you would hit Command-V during startup, which brings up the familiar white on black console. If you’d prefer to always see the system messages on boot, you can adjust the firmware from the Terminal with the nvram command.
To turn on Verbose booting, at the Terminal type the following:
sudo nvram boot-args="-v"

Disabling Verbose booting is just as easy:
sudo nvram boot-args=

If you’re curious what the current firmware nvram settings are, type the following:
nvram -p

Again, if you just want to boot into verbose mode once, hold the following keys on system boot:
Command+V

You need to launch Activity Monitor and note the Process ID for FCP.

Then launch Terminal and type “sudo renice -20 ProcessIDHere”.

In the above example you’d put the Process ID for FCP in the obvious spot. The “-20″ is the highest priority you can give a program. The lowest would be “20″.

After you type that line above into Terminal it’ll ask you for your adminstrative password.

It’ll then show something like:
“ProcessIDHere: old priority 0, new priority -20″

All apps in OS X are a Priority 0, but using the renice command can tell OS X which apps you want to give more juice to.

To show hidden files in Finder pop open your terminal and type the text shown in the screen grab below.

To go back to hiding files we obviously just flip the AppleShowAllFiles flag to FALSE.

*Update*
As noted in the comments its nice to have the text available for easy copy and paste into your terminal.

Show:

defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder

Hide:

defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder

*Update 2*

You can use this script toggle between states:

# check if hidden files are visible and store result in a variable
isVisible=”$(defaults read com.apple.finder AppleShowAllFiles)”

# toggle visibility based on variables value
if [ "$isVisible" = FALSE ]
then
defaults write com.apple.finder AppleShowAllFiles TRUE
else
defaults write com.apple.finder AppleShowAllFiles FALSE
fi

# force changes by restarting Finder
killall Finder

You can also download an Automator application which will toggle hidden file visibility here:

1. We need to find the UUID for the disk.  We can only get that via the slice number, so, we get that first:

# diskutil list
/dev/disk0
#:                  type name              size      identifier
0: Apple_partition_scheme                    *76.7 GB  disk0
1:    Apple_partition_map                    31.5 KB  disk0s1
2:              Apple_HFS StuC_HD            76.6 GB  disk0s3
/dev/disk1
#:                  type name              size      identifier
0: Apple_partition_scheme                    *279.5 GB disk1
1:    Apple_partition_map                    31.5 KB  disk1s1
2:              Apple_HFS StuC_HD_Backup    139.6 GB  disk1s3
3:              Apple_HFS backup2            139.6 GB  disk1s5

Great!  Stu_C_HD_Backup is “disk1s3″

2. Now, let’s get the UUID:

# diskutil info disk1s3
Device Node:        /dev/disk1s3
Device Identifier:  disk1s3
Mount Point:
Volume Name:        StuC_HD_Backup

File System:        Journaled HFS+
Owners:            Disabled
Partition Type:    Apple_HFS
Bootable:          Is bootable
Media Type:        Generic
Protocol:          ATA
SMART Status:      Verified
UUID:              CDCDFBA1-EF2C-39FA-998B-94C63B8F23E1

Total Size:        139.6 GB
Free Space:        0.0 B

Read Only:          No
Ejectable:          No
Device Location:    “B (lower)”

Note the “UUID” line.  Copy the UUID value.

3. Edit /etc/fstab – the “File System Table”.

his file may not exist, so, you’ll be creating it from scratch.  You can read the fstab man page for more info, but the idea is this: the system looks to this file to gather mount options for disks.  Since OS X doesn’t guarantee assigning the same device id to the same disk each boot, we need to tell the system to use the same mount options for a particular UUID.  The option we need to pass is the ‘noauto’ flag.  Here’s the /etc/fstab entry for the disk in question:

# fstab
# Created 28 March 2006
# Ed Marczak

# Identifier, mount point, fs type, options, dump order, check order

This is for HFS
UUID=CDCDFBA1-EF2C-39FA-998B-94C63B8F23E1 none hfs rw,noauto 0 0

This is for NTFS

UUID=CDCDFBA1-EF2C-39FA-998B-94C63B8F23E1 none ntfs rw,noauto 0 0

UUID= (Insert your drive’s exact UUID here) none ntfs ro,noauto 0 0

For FAT32 formatted drives, replace “ntfs” with “msdos”. Exit and save with ctrl+x (it will prompt you to save the changes).

4. Reboot, and you’ll see that the partition in question hasn’t mounted.

What is Single Application mode?

Single Application Mode is a way to force Mac OS X to show only the application that is currently in use, all other open applications and windows will be minimized into the Dock. Selecting another application from the Dock will then minimize the current application, and the new selection becomes the only thing on screen. I have heard this feature was originally intended for presentation purposes when showing off Mac OS X, but it’s actually a handy way to avoid distractions and maximize screen space on smaller resolution displays.

How to enable Single Application mode in Mac OS X

Enabling this feature is done through the command line, so launch the Terminal then enter the following commands exactly:

defaults write com.apple.dock single-app -bool true

For this to take effect, you now must kill the Dock:

killall Dock

You can reverse single application mode and get back to multiple application mode easily by changing the original command as follows:

defaults write com.apple.dock single-app -bool false

and again, killing the Dock:

killall Dock

Here are the modifier key symbols you can see in Mac OS X menus:

 (Command key) – On some Apple keyboards, this key also has an Apple logo ()
 (Control key)
 (Option key) – “Alt” may also appear on this key
 (Shift key)
 (Caps Lock) – Toggles Caps Lock on or off
fn (Function key)

Startup keyboard shortcuts

Press the key or key combination until the expected function occurs/appears (for example, hold Option during startup until Startup Manager appears, or Shift until “Safe Boot” appears). Tip: If a startup function doesn’t work and you use a third-party keyboard, connect an Apple keyboard and try again.

See also: Startup key combinations for Intel-based Macs.

Finder keyboard shortcuts

Application and other Mac OS X keyboard commands 

Note: Some applications may not support all of the below application key combinations.

(*) Note: If no text is selected, the extension begins at the insertion point. If text is selected by dragging, then the extension begins at the selection boundary. Reversing the direction of the selection deselects the appropriate unit.

Universal Access - VoiceOver keyboard commands

For information about VoiceOver key combination differences in Mac OS X v10.6, see this article.

Note: You may need to enable “Use all F1, F2, etc. keys as standard keys” in Keyboard preferences for the VoiceOver menu and utility to work.

Universal Access – Mouse Keys

When Mouse Keys is turned on in Universal Access preferences, you can use the keyboard or numeric keypad keys to move the mouse pointer. If your computer doesn’t have a numeric keypad, use the Fn (function) key.

If you need to record screen activity on a Mac, you don’t need to download any additional software because the functionality is built directly into Mac OS X.

Using the Screen Recorder in Mac OS X

The screen recorder function is included with QuickTime Player in Mac OS X 10.6 and later, meaning it’s free and doesn’t require any downloads. Here’s how to use it:

• Launch QuickTime Player (located in /Applications/)
• Pull down the File menu and select “New Screen Recording”

• Press the Red button to start recording the screen activity
• To stop recording, either press the Stop Recording button in the menubar, or hit Command+Control+Escape
• Once the recording is stopped, the capture is automatically opened in QuickTime Player as “Screen Recording.mov” which you can then save and use as you’d like

QuickTime Player gets out of the way when you are recording the screen so that the activity is not obstructed by the application, this is also why it’s best to just use the keyboard shortcut to halt the screen recorder.

You can check your entire print history in Mac OS X by accessing the browser based CUPS utility. Here’s how:

• Launch your web browser (Like Safari and Chrome)
• In the address bar type in: http://localhost:631
• Click on “Jobs” in the menu
• Now click “Show Completed Jobs” to display your Macs print history

You’ll now see the printer, name of the file that was printed, the user who completed the print job, size of the printed document, the number of pages, and the date of the printed file completion or attempt.

If you are looking for a specific event, you can use the “Search in Jobs” search engine to find a file. You can also select “Show All Jobs” to see everything you’ve printed or attempted to print, even if it failed.

CUPS stands for Common UNIX Printing System and is an open source printing system developed by Apple for Mac OS X and other UNIX based operating systems. The web based CUPS tool is a great way to troubleshoot misbehaving printers.

While we’re on the topic of printers, if you haven’t yet, you can make any printer AirPrint compatible by using a third party tool. Without this tool, AirPrint wireless printing is limited to a select few printers.

As most modern OS’s go, Mac OS X is generally pretty intelligent with how it prioritizes processes. That said, if you want to give any running task an extra kick in the pants, you can use a free tool called Process Renicer. Launching the app gives you a task manager of sorts where you can double-click on any running process and then adjust it’s “nice” value to increase it’s CPU priority. The app is basically just a GUI frontend to the command line tool ‘renice’ which is generally for advanced users.

Giving any task a lower nice value will up it’s priority, and giving it a higher nice value will lower it’s CPU priority. This sounds paradoxical, but that’s just the way it works.

Most users won’t need an app like this, but if you want to push along a video conversion for your iPhone or something similar, you can do so. Remember that if you adjust the nice process downward dramatically, your CPU load is going to go through the roof and ignite your fans.

Sometimes the easiest fix when troubleshooting an AirPort wireless connection problem is to just turn AirPort on and off. Instead of using the menu item or System Preferences, we can enable and disable AirPort very quickly directly from the Mac OS X Terminal.

Turn Airport Off via Command Line
networksetup -setairportpower airport off

Turn Airport On via Command Line
networksetup -setairportpower airport on

You won’t see any confirmation in the Terminal that the command succeeded or failed, but if you watch the AirPort menu icon you will see the bars disappear indicating the wireless interface is turned off, or reappear indicating that wireless is activated again.

We can also string the commands one after the other to power cycle the wireless interface on a Mac:

Quickly Power Cycle AirPort with Mac OS X’s networksetup Tool
networksetup -setairportpower airport off; networksetup -setairportpower airport on

The AirPort wireless card seems to respond faster to the command line networksetup tool than any other method, making this an ultrafast method of power cycling the wireless interface. This is often enough to resolves basic wireless router connectivity issues like IP conflicts or malfunctioning DHCP requests.

I have enough regular encounters with one particularly flakey router that I created an alias to power cycle my AirPort card, you can do this by adding the following to your .bash_profile just be sure it is on one line:

alias airportcycle='networksetup -setairportpower airport off; networksetup -setairportpower airport on'

Now like any other alias, you only type ‘airportcycle’ and the wireless interface will immediately turn itself off and on again.

Disabling and reenabling AirPort is not the same as connecting to a wireless network from the command line, although you can do that too also by using the networksetup tool.
