Lukas Pitschl released a bugfix version for GPGMail. It works with Snow Leopards Mail.app (32bit only). Grab the file http://dl.getdropbox.com/u/20215/GPGMail-1.2.1.mailbundle.zip and drop it in your /username/Library/Mail/Bundles folder. Make sure mail.app is not running. Relaunch after the file is dropped in.

you can also try the official http://sourceforge.net/projects/gpgmail/ project. Not sure if this one works yet.

Apple will release Snow Leopard retail soon. At the time I'm writing this, macports 1.7 (known as darwinports) are not working well with previous builds of Snow Leopard. I'm sure that everything will work out of the box with macports > 1.7.1 a few weeks after the retail release of OSX 10.6 in September 2009. Make sure to install Xcode from the 10.6 DVD! It will update gcc to version 4.2. My description wont work with old gcc 4.0 from 10.5.

To improve our chance for a working ports tree, we have to use the latest subversion source code (August 2009).

1. Open up the Terminal
2. svn co http://svn.macports.org/repository/macports/trunk/base/ (Wait for it to finish checking out files)
3. cd base
4. ./configure
5. make
6. sudo make install
7. sudo /opt/local/bin/port -v selfupdate

I had to add /Developer/usr/bin and /Developer/usr/sbin to my .bash_profile
export PATH=/Developer/usr/bin:/Developer/usr/sbin:/opt/local/bin:/opt/local/sbin:$PATH

There are mailing list entries about problems with compiling python on Snow Leopard. This might change soon but be aware of such problems.

Update:Use sudo port upgrade --enforce-variants and then sudo port upgrade outdated to update all your old installed ports after selfupdate.
If you see errors like: ld: warning: in /opt/local/lib/libz.dylib, file is not of required architecture then you've to remove zlib and libiconv as installed ports and re-install it again.

sudo port uninstall -f libiconv zlib
sudo port install libiconv zlib

This may break some old dependencies. If so then you have to rebuild all related ports as well.

A friend of mine recommended an interesting PDF tool to me. Skim is a PDF reader and note-taker for OS X. It is designed to help you read and annotate scientific papers in PDF, but is also great for viewing any PDF file. Best things are free

ClickToFlash is a WebKit plug-in that prevents automatic loading of Adobe Flash content. If you want to see the content, you can opt-in by clicking on it or adding an entire site to the whitelist.

Ram disk is the use of a part of read-write memory (RAM) as a hard disk. Creating a ram disk on OS X is easy with shell commands. But as we know, most Mac users prefer a GUI. Esperance DV is a module for System Preferences making a ram disk (memory disk). You can place temporary files for speed saving video, speed recording a lot of pictures, building your application with xCode,...

Have you ever tried to dim your iMac display? Apples iMac default brightness controll is not very satisfying.

Charcoal Design Shades is a little application that gives you fine control over how bright or dim your iMac's display is. It runs in the background providing always-available fine-grained control over the brightness of your display via a Mac-like interface. It performs this without actually changing the real brightness of your display. It applies an opacity filter to your Desktop similar to Splasms Software Brightness Control

Both tools have no power saving effect! Shades is available as ppc, intel and universal binary.

I assume DarwinPorts are already installed (http://darwinports.com/install/). All my examples are done with lftp a powerful command line ftp client (System: OS X 10.5.3 intel).



Update the darwin ports tree:
sudo port selfupdate

Search for a port. The search facility uses standard regular expression syntax for complex searches:
sudo port search 'lftp'

Check what variations of that port are available to use. Variants provide additional configuration options for a port:
sudo port variants lftp

See what dependencies a port has:
sudo port deps lftp

Find out which ports depends on a already installed port:
port dependents

Install a port:
sudo port install lftp

Delete all the intermediate files that DarwinPorts has created while building the port:
sudo port clean lftp
sudo port clean --all lftp

Getting Information about installed port:
sudo port info lftp
sudo port contents lftp

Show all installed ports:
sudo port installed

Check if lftp is outdated (ports tree should be up to date):
sudo port outdated lftp

Show all outdated ports (ports tree should be up to date):
sudo port outdated

Upgrade lftp port:
sudo port upgrade lftp

This will deactivate the old version and install the new. It also install the latest versions of the dependencies of the lftp port.

Just upgrade a port without the dependencies of this port:
sudo port -n upgrade lftp

Upgrade ALL installed ports (could take ages):
sudo port upgrade installed

Uninstall a port:
sudo port uninstall lftp

Uninstall inactive ports (makes sense after a port upgrade):
sudo port -f uninstall inactive

Brave poeple can use (read: man port for all options):
sudo port -fvdRnu upgrade outdated
sudo port -fvdR clean --all installed
sudo port -fvdR uninstall inactive
sudo port -fvdR clean --all uninstalled

Most OSX User know the great HandBrake video tool. It's a GPL'd multiplatform, multithreaded DVD to MPEG-4 (h264/Xvid) ripper/converter. HandBrake was originally available on the BeOS, but has been ported over to MacOS X and to GNU/Linux. It's a great tool but it missed a few features like the recently introduced iPod features (H.264 Baseline Low-Complexity, larger size) for TV size videos.

The MediaFork project started as an independant effort to add features and enhancements to the latest HandBrake codebase and provide users with updates. The first public beta, MediaFork 0.8.0b1, was released yesterday with significant enhancements over HandBrake 0.7.1 (see the full changelog on the MacUpdate page - MediaFork’s server has been under heavy load since the release and went down).

Let’s be clear that MediaFork is not a concurrent project. It's available for OSX (UB), Linux and Windows.

OSX 10.5 (codename: Leopard) is knocking on our doors. It offers a lot of enhancement compared to OS X 10.4 like virtual desktop, timeshift (backup feature), ZFS or tabed terminal support.
But let's face the reality, OSX 10.5 is not available right know and it certainly takes some time until it's stable as 10.4. Also most upcoming features are available for 10.4 as well with third party programs.
iTerm is one of this tools. It gives use the possibility to use multi tab within one window. iTerm is a full featured terminal emulation program written for OS X using Cocoa. We are aiming at providing users with best command line experience under OS X. The letter i represents a native Apple look and feel of the program interface, and an emphasis on complete international support. iTerm was merged from two projects, CTerminal and TerminalX, both of which were based on JTerminal project. The current version is still in beta stage. It is however very much functional and usable.

Have you ever wonder about syncing iTunes with your PSP’s, your PDA’s, and your MP3-capable cell phones. In short, many people with a Mac, iTunes and a PDA or phone with audio playback capability, or non-iPod music player. From user reports, SyncTunes transfers files that work with Palm PDAs, Sony PSP, Sony Ericsson K750/P910/W800i, no-brand MP3 player. It is probably compatible with other audio players too, except iPods which have a special database file.
A great application and it's free.

Maybe you got an iPod for Christmas and maybe you like to read RSS feeds like my one.
iFeedPod collects all the news from your feeds, and copies them to your iPod for you to read wherever you have the time (requires an iPod,iPod mini or iPod Nano with Notes facility).

Apples application switch implementation is pretty usless. The key combination "option+tab" opens just the application it belongs to. Even windows has a better app switch function with "alt+tab".
While you can use Exposé to switch windows, doing so can be very clumsy if you're the keyboard-only type of user. And don't all of these windows look just the same when they are scaled down?
Witch lets you access all of your windows by pressing a shortcut and choosing from a clearly arranged list of window titles



Moreover, you can use Witch to...

Directly access minimized windows without using your mouse

Close minimized windows without bringing them to front first

Zoom, de-/minimize, and close windows on the fly
