Delete incorrect Mail addresses

I’ve entered some incorrect addresses when addressing new e-mail messages in Apple’s Mail. Now when I create a new message and enter the first couple of letters of an address, these unwanted addresses appear. Since they haven’t been entered on a card in Address Book, I can’t find them to delete them. How can I rid myself of these bad e-mail addresses?—Helen Pressel

When you create an e-mail message and type the address in Mail, the program puts the address—whether right or wrong—in its cache. To remove cached addresses in the version of Mail that shipped with OS X 10.2.8, select Window: Address History, select the incorrect address in the resulting Address History window, and click on Remove From History.

In Tiger’s version of Mail, go to Window: Previous Recipient and do the same. The command’s name is different, but it works in a similar way. In the Panther and Tiger versions of Mail, you can remove these addresses by allowing Mail to automatically complete the incorrect entry, control-clicking on the address, and then selecting Remove Address from the contextual menu (see “Boot Bad Addresses”).

Raise the dead drive

I installed the Tiger (OS X 10.4.3) update, and now my Power Mac G5 can mount DVD movies but refuses to play them. What’s wrong?—Via the Internet

If you’ve been using your Mac for longer than the life span of a moderately hearty butterfly, you’ve heard that after installing an OS upgrade—say from OS X 10.4.1 to OS X 10.4.2—you should immediately dash to Apple’s Disk Utility (/Applications/Utilities), select your startup drive from the list of drives at the left of the Disk Utility window, and click on Repair Permissions to put any errant file permissions back in line. I’ve found doing so to be an absolute necessity for this particular update.

After I installed the update on my brand-new 20-inch iMac G5, the SuperDrive refused to read a perfectly legitimate software CD. Spin enthusiastically, it would, but mount, it would not. When I repaired the Mac’s permissions, a slew of out-of-whack ones appeared in Disk Utility’s main window. With these fixed, the drive worked as it was supposed to.

I’m aware that a new update may be out by the time you read this. Regardless, this advice applies from now until Apple says there’s a better way. Repair permissions after every update.

Save your receipts!

I can’t use Apple’s Disk Utility to repair permissions on my 500MHz Titanium PowerBook G4. When I try, I see an error that reads “No valid packages.” What’s going on?—Ayrton Camargo

You can’t repair permissions if you’ve moved the BaseSystem.pkg file in your Mac’s /Library/Receipts folder. Regrettably, there’s a notion floating around the Web that it’s perfectly okay to toss the contents of this Receipts folder to free up space. But if you misplace this particular file, which was created when you installed OS X, you encounter this error.

Each package, or .pkg file, in your Receipts folder contains a bill of materials, or .bom file, that keeps track of permissions for the items installed from that package. Disk Utility uses that information to compare the permissions of files on your hard drive with the permissions listed in these .bom files.

If a receipt (and its accompanying .bom file) is missing, Disk Utility can’t verify the permissions at all. In most cases, this isn’t a huge problem. Disk Utility goes on about its business because it’s unaware of the missing receipt. But it becomes a big problem if the BaseSystem.pkg file is missing, because Disk Utility relies on this particular package to do its job.

The solution to the problem is to put the BaseSystem.pkg file back in the Receipts folder. If you’ve intentionally removed and deleted it, either pull a copy of the file from a backup you’ve created or find a Mac buddy who’s running your PowerBook’s version of Mac OS, grab a copy of this file from his or her computer, and plunk it into the Receipts folder on your Mac.

If you’re buddyless, you can put things right by performing an Archive & Install installation of Mac OS.

Resurrect Sherlock

My copy of Sherlock appears to be dead, and I don’t know how to get it up and running again. It worked well under previous versions of OS X but broke when I installed OS X 10.4.—Louise Wazbinski

This behavior could be seen as a fairly broad hint that Sherlock’s days are numbered, because most of its capabilities are duplicated by Tiger’s Dashboard widgets. (Hold those angry cards and letters, please—I’m not saying that widgets are better than Sherlock; I’m saying only that the writing is on the wall.)

But that doesn’t mean Ican’t help you. You simply need to clear Sherlock’s virtual throat and allow it to start fresh. Dig through your user folder and toss the following folders and files into the Trash:

> / your user folder /Library/Caches/Sherlock/

> / your user folder /Library/Preferences/ Sherlock/

> / your user folder /Library/Preferences/com .apple.Sherlock.plist

Dot not

I used Panic’s news reader, Unison, to download a folder full of files. I can’t find that folder anywhere on my hard drive, and Spotlight can’t find any of the files. Yet when I click on the Show File icon in Unison’s Downloads window, the file appears in the group folder that contains it. Where is everything?—Bill Phillips

This quirk from an earlier version of Unison has now been addressed. If you used a utility such as Marcel Bresink’s free TinkerTool to make your Mac’s invisible files visible, you’d find your folder right where it should be—inside the group folder ( alt.binaries.sounds , for example) where Unison stores its downloads.

The problem is that the file or folder’s name probably begins with a period (.). You see, the Finder won’t allow you to create a file or folder with a name beginning with a period, but it’s possible to download one. Unfortunately, that’s the naming convention for special items reserved for the system’s use. OS X makes all such items invisible so you can’t mess with them by accident.

The trick to making the folder visible is changing its name, but the Finder may prevent you from doing so in the normal way—highlighting the name in the Finder and removing the period. Instead, select the folder’s name, press Command-I to bring up the Info window, and rename the folder by typing in the Info window’s Name & Extension text field.

Get the Joke Don’t let yourself be overwhelmed by e-mails that you want to save but that have unhelpfully generic subject lines. With the aid of a nonsense word and a well-constructed Mail rule, you’ll have the last laugh.

Change the subject

A friend sends me tons of funny e-mails, but they all have the subject heading “Humor.” I save the ones I like in a folder, but I can’t tell them apart. If I could change the subject heading, reviewing the items in this folder would be a lot easier.—Jim Ross

The most effective solution would be to contact the sender and ask him or her to create a subject heading that reflects the contents of each message. But I imagine you would have contacted Dear Abby instead of Mac 911 if you wanted the social solution to your problem. To avoid what could be an awkward e-mail exchange, try this instead.

Launch Mail, hold down the Command and option keys, and click on the transparent button in the upper right corner of the window to produce the sheet that lets you customize the toolbar. Drag the Redirect icon to the toolbar.

When you receive a joke that you like, click on the Redirect button. In the message window that appears, enter your name in the To field and type in a subject heading that more accurately describes the yuckfest within. Send the message to yourself.

To more easily file the message when you receive it, add a made-up word to the subject that will help you filter the message with a rule. For example, you could use the fake word Laff in the subject line—“Laff: Chicken Crosses Road.” Click on the plus-sign (+) button at the bottom of Mail’s Mailboxes pane and create a new mailbox named Laffs. Now choose Mail: Preferences, click on the Rules tab, click on Add Rule, and create the following rule: If Subject Contains Laff, Move Message To Mailbox Laffs (see “Get the Joke”).

If you’d rather not e-mail yourself, go ahead and click on Redirect, enter any e-mail address you like, change the subject, and then click on Save As Draft. Mail will move the message to its Drafts folder; then you can move it to another folder.
