How to Create .ZIP Files without a __MACOSX Folder

The problem: I want to send a folder full of files from my Mac to my friend’s PC. When I right-click on the folder and choose the archive option, the resulting .ZIP file includes a folder called __MACOSX, along with several files that begin with a dot.

The solution: Use YemuZip, which has a PC-specific option that eliminates these files. Another option is Compress, which is a simpler application.Compress can handle many file types such as .ZIP, .7ZIP, and .TAR while YemuZip can only output to .ZIP files. However, YemuZip allows the user to specify the location of the output, while Compress does not.

Easy Uninstalling with AppTrap

When you want to uninstall an OS X application, you want to delete the supporting files as well. This is exactly the reason behind AppTrap, a donation-ware application.AppTrap installs itself in the System Preferences, which provides only one option: on or off. Once turned on, AppTrap watches for application deletion. Once detected, AppTrap displays a window asking if the user wants to delete the supporting files as well. The software is intuitive, the interface is simple which makes the software a joy to use.

Reset Printing System to Solve Printing Problem

My wife has been having problem printing to a shared printer across my 802.11g network for the last couple of days. After some un-fruitful research, I took her laptop to a local Apple store and asked for help. Here is the instruction the Genius gave me to solve our problem.

The problem

I have a MacBook which has two printers (HP LJ3015 and Epson Rx580) attached to it via a USB hub. I share these two printers so that my wife’s G4 iBook can print to them across our 802.11g wireless network. All is well until one day when she tried to print a document, it took about a minute or two for the print dialog box to come up, then another minute or two trying to print before giving up with the following terse message:

Print Error Dialog

To debug the problem, I fired up the console application and received the following errors:

PMSessionValidatePrintSettings failed (error code = -50)
PMSessionBeginPageNoDialog failed (error code = -30871)
Failed to PMSessionBeginPageNoDialog

The Solution

On my MacBook, start the Printer Setup Utility application, click on the Printer Setup Utility menu (AKA main menu) and select Reset Printing System… This will remove all the printers. Afterward, add those printers again. They are not yet shared so the next step is to share them via the Sharing tab within the Printer & Fax preference pane.On my wife’s iBook, go through the steps to reset printing system and re-add the printers as described above. After going through these steps, my wife was able to print from her iBook again.
