Notes about problems

The new Grass version is used and it works very well for many users but not for all. These notes are for users with problems.

PROBLEM
Some users have problems at the start with a GUI that disappears.

SOLUTION
This problem is resolved if you have your system up-to-date: install last security update from Software Update menu.


PROBLEM
Grass stopped at the start with an error about PostgreSQL library presence or MySQL library presence.

SOLUTION
Download and install PostgreSQL for Mac OS X from PostgreSQL site or other sources and download and install MySQL for Mac OS X from MySQL site.

Startup application problem

There is a problem in the startup application of Grass GIS 6.3.0-2. You can not change the Grass version, OS X or X11, and Grass start always in one way. This problem will be fixed in the next version 6.4.0 but if you want to use Grass X11 open Terminal application and enter this command:

$  defaults write com.lor.grassgis checkgrass "X11"

If you want to return to Grass OS X opern Terminal and enter this command:

$  defaults write com.lor.grassgis checkgrass "OS X"

Or if you want the hybrid enter:

$  defaults write com.lor.grassgis checkgrass "X11-OS X"

If you want to change the language enter (example):

$  defaults write com.lor.grassgis grasslanguage "en_EN"
