DR. GIRLFRIEND  No prob here. Did you have Mail open or closed when you installed it? I had Mail closed and didn't have any previous versions of Letterbox installed.

KANKEI71  Thank you. I got it... I'm still on 10.5. I thought this new version would be OK for Leopard AND Snow Leopard, which is not the case. All fine now.

NEPLOLEPPARD  I couldn't get anything but the background to change. After setting the login the way I wished, I hit apply. Then I checked the login screen and only the background worked.

NOVICIUS  You can build the source and let it install the files to the default locations /usr/local/... etc, and you can use it by manually. But it is BETA.

I hope this answer is not too short ;)

Using from terminal:

cd /usr/local/sbin

sudo ./privoxy --user privoxy.privoxy /usr/local/etc/privoxy/config

Build:

The instructions are in the INSTALL file. Just write "make", press enter and answer yes when it wants to do the autoheader && autoconf etc. If you would like to run privoxy with special user called "privoxy", you must google the instructions for creating the user etc. or check if you already have it. In 10.5: "dscl localhost list /Local/Default/Users" or something similar. In 10.4. you can use GUI program from System Utilities, was it Directory or what??

After build, install it: "sudo make -s install USER=privoxy GROUP=privoxy".

When the installation succeeded, copy the missing files as instructed in below.

You can still use the Startup Item in OSX 10.4. and 10.5. even it is not supported anymore. The stuff we need is at the end of this text. The newest approach is the launchd daemon. I wrote a basic solution for this only for testing privoxy so no further support is coming from me.

If you would like to use the current Privoxy Utility (mine was v. 1.2), you choice is the Startup Item. Use only one solution.

My privoxy is build as default and installed as "make -s install USER=privoxy GROUP=privoxy" to the 10.5. environment.

Launchd:

1. write a property list file inside /Library/LaunchDaemons/ and save it as org.privoxy.privoxy.plist

2. change the owner to the root and and the group to the wheel, and give everyone only read rights.

3. boot the system and check if privoxy is running and the system logs are not reporting any errors.

Startup Item:

1. create the Privoxy folder inside /Library/StartupItems/

2. write a property list file named StartupParameters.plist and a shell script named privoxy inside the Privoxy folder (plain text file).

3. the owner must be the root, the group is the wheel and the rights for the plist are rw-r--r--. So only the owner has write access. The folder and the shell script needs also the execute rights: rwxr-xr-x. If you don't change the rights, OSX will fix it after next system boot if you allow.

4. Boot the system, start the Privoxy Utility and check that it is working.

FRANCKY76  Yes, it's exactly what i am going to use it for. KP is a very unsual situation and must be recognised by newbies. Thanks to the develloper.
