There have been a number of reports that the Leopard Finder silently ignores your wish to eject disks and disk images, no matter if you click the Eject button in the Finder's sidebar, drag the disk to the Trash, or right-click and choose Eject. The only simple work around was using the hard disk utility.
I had the same problem with my MacBook Pro for the last couple of month -- and accidentally found a solution looking at the recent version of Onyx. In Onyx, you have the option to remove the Eject Disk menu item from the File menu of the Finder. It turned out that at some point in the past I had removed that item, and then forgot about doing so. Restoring the missing menu solved the above problem.
Of course, I do not know if this is of any help for other people with the same disk eject problem.
If you prefer being able to focus on one application at a time, you may find this hint useful -- it sets the Dock to automatically hide every application other than the one you're switching into. So when you click on Mail, for instance, the effect is as though you activated Mail and then chose Mail -> Hide Others (or pressed Command-Option-H).
To enable this switching mode, open Terminal and type these commands:
$ defaults write com.apple.dock single-app -bool TRUE
$ killall Dock
From now on, clicking on an application in the Dock will hide all other open apps while switching to the selected application. You will not see this behavior if you use Command-Tab to switch, or click directly on another application's windows. To disable the feature, repeat the above commands, but replace TRUE with FALSE. (Alternatively, you can delete the entry entirely with defaults delete com.apple.dock single-app.) Remember to restart the Dock as well.
For an easier method of implementing this feature, see this hint.
Spector is a package that takes periodic screen captures of your system. It then saves these as hidden files on your computer somewhere, and can be set up to email them to someone at set intervals. To check if you have Spector on your machine, type top into the Terminal (or load up the Activity Monitor). You're looking for a process called DriverSPD. If that process appears, someone has installed Spector on your computer.
To remove the Spector process (you need to be an admin user to do so), just go into /Library/StartupItems/ and delete LiloDS, DriverSPD, SystemStart, SystemStartState, and StartupParameters.plist. Log out and log back in, and DriverSPD should no longer appear in Activity Monitor. You'll also want to remove the snapshots/keylog files that Spector saves on your computer. In fact, if someone has installed this program on your computer, and you don't want them to know you found it, you may just want to delete certain snapshots, etc. Anyways, here's how you do it...
If you move the Dock from the bottom to the right side of your desktop, you may find that the icons on the right side of your Desktop become partially hidden underneath the Dock. This is both ugly and makes it more difficult to click on those icons (such as your hard drive's icon). What you want to happen, of course, is for the desktop icons to move over towards the left in order to make space for the Dock.
For some reason, Finder doesn't reset the icon grid on the desktop when the Dock is moved to the side of the screen. A quick Google search on this issue revealed nothing more helpful than the suggestion to set the Dock to automatically hide. But there is an easy way to get the Finder to move the desktop icons out from under the Dock.
Click on the Desktop, select Show View Options from the View menu, and slide the Grid Spacing slider around. As soon as you do this, the grid will be reset to respect the position of the Dock, and will move your desktop icons out from underneath the Dock. You can then put the slider back into the same position you had it before, and close the View Options palette.
If you are running your laptop on the battery, and want to temporarily prevent the screen from dimming after a short period of inactivity, you can use the 'Disable Screensaver' hot corner (set in the Desktop & Screen Saver System Preferences panel) to also prevent the screen from dimming.
In my tests, the screen would dim after 60 seconds of inactivity when display sleep was set to five minutes.
You can also permanently turn off screen dimming by opening the Energy Saver System Preferences panel. Select Settings for Battery, click the Options tab, and uncheck 'Automatically reduce the brightness of the display before display sleep.'
I needed to create a text clipping that contained the "@" character, but couldn't, because MacOS creates dragged text containing an "@" character as an email link. See for yourself: Select the following text -- xxxx+yyyy -- then drag it to your Desktop. This creates a text clipping file named xxxx+yyyy.textClipping. Now select the following text -- xxxx@yyyy -- and drag it to your Desktop, and notice that the file is named firstname.lastname@example.org, and its icon says MAILTO. If you drag and drop this text into a program, it will get pasted as mailto:email@example.com.
The solution requires editing the xxxx+yyyy.textClipping clipping file. This requires several steps:
Extract the contents of its resource fork into a temporary file (using a receipe from this
Edit the temporary file
Write the temporary file back into the resource fork.
I just bought a new aluminum MacBook, and discovered that I couldn't get an IR remote control to pair with the notebook. This is optional, but it prevents other remotes from controlling your Mac.
If you go to the Security System Preferences panel, you'll find a Pair/Unpair button. Clicking on Pair brings up a message instructing you to press and hold the Menu and Next buttons on the remote until a "paired" icon appears.
I tried this several times with no luck. Finally, I found that you have to be running an admin account for this to work -- there is no indication that you can't pair from a non-administrator account. As a matter of fact, the panel is disabled until you click the lock and enter an admin account and password. But even after unlocking, you still can't pair from a standard account.
So if you have trouble pairing a new remote, make sure you log into an admin account first.
Sometimes after switching from one application to another, and then trying to return to the first, I'll find that it won't come forward -- because the first application is doing a long calculation, or something else that makes it freeze. I want to see the current window state for the frozen application, but I can't do it until the program has finished doing whatever it's doing.
For those times when I just can't wait, I think I found the solution: Exposť. Just press F9 (or whatever key you've assigned to All Windows), or move your mouse to the All Windows screen corner, if you've set that up. Then just click on the frozen window, and it should come to the foreground (though it won't update until the long calculation is done).
Other hints, such as this one, describe how to keep an application alive using launchd. problem with this technique is that applications (re-)started this way inherit launchd's environment, not the user's, and so don't include any environment variables defined in ~/.MacOSX/environment.plist
If that's a problem for you (it is for me), then you can include those variables by launching the application indirectly, from a script which parses the environment.plist before invoking the application. Save the script below to a file called LaunchWithToplevelEnvironment.sh (or whatever you like) in ~/Library/LaunchAgents, then make that script executable (chmod a+x script_name):
This is the simplest way I've found to toggle the AirPort card on and off without using third party applications or too many buttons. Hopefully others will appreciate this function as I do. Note: This function is tailored to a MacBook, as the F5 and F6 keys have no predetermined function on these machines. Other machines may need the shortcut keys to be edited.
Create two keyboard shortcuts. Go to the Apple menu » System Preferences » Keyboard & Mouse » Keyboard Shortcuts tab. Click the plus sign at the bottom of the window, and select All Applications from the pop-up menu in the next dialog. In the Menu Title box, type Turn AirPort On with that exact case and spelling. Set the Keyboard Shortcut to F5, then click Add. Click the plus sign again, leave the pop-up menu set to All Applications, and in the Menu Title box, type Turn AirPort Off with the shortcut key also set to F5 -- only one of these functions will be displayed at a time.
In the Keyboard Navigation section of the same window, change the 'Move focus to status menus in the menu bar' to F6 (and check the box to enable this shortcut, if it's not yet enabled).
Make sure the AirPort icon is in your menu bar. Then hold down the Command key and drag the AirPort Menu bar icon as far to the left as possible. This insures that it is the first to be selected when you move focus to the menu bar.
Finally, restart your system.
After your Mac reboots, press F6 to move focus to the menu bar, and F5 to toggle AirPort on or off, depending on its current state.
