Uninstalling Lazarus on macOS
│ English (en) │
This article applies to macOS only.

Installed using fink
If you installed Lazarus + FPC using fink, the complete uninstall of all Lazarus + FPC packages is done with:
fink purge --recursive fpc-config
If you want to preserve changes to the preference file /sw/etc/fpc.cfg, do:
fink remove --recursive fpc-config
For the removal of the Lazarus preferences subdirectory in your home directory, and the files that it contains, see the end of the next section.
Installed using the official packages
Normally you uninstall an application on macOS simply by dragging it from the Applications folder to the trash. As Lazarus and Free Pascal are development tools, they install files in several folders that you don't normally see in Finder and so the normal approach does not work.
You can usually install newer versions of Lazarus over older versions, while newer versions of Free Pascal are installed in unique directories. However, as with most software it's not a bad idea to clean out everything before you install a newer version. The two scripts below should give you a sense of where the various pieces of Lazarus and Free Pascal are located.
You can copy and save the commands from one of the following scripts to a file, say uninstallLaz.sh, and run it if you need to uninstall Lazarus and Free Pascal.
FPC 3.x.x and Lazarus 2.0.8 through 2.0.10
The script below will delete all versions of FPC and Lazarus which have been installed in the targeted locations using the official Lazarus installation packages (which also install FPC). These locations are correct for FPC 3.x.x and Lazarus 2.0.8 through 2.0.10.
#!/bin/sh

To run either of the above scripts, open an Applications > Utilities > Terminal, and enter:
cd <replace this text and angle brackets with the name of the directory where the script is stored>
chmod +x uninstallLaz.sh
sudo ./uninstallLaz.sh
Then enter your password when prompted.
Lazarus preference folder .lazarus in the home directory
Lazarus also creates a .lazarus preferences subdirectory in your home directory where it stores environment settings and a list of recently opened projects and files. You can leave this folder alone if you want the new version of Lazarus you're installing to use your old settings. macOS normally doesn't show files or folders whose names start with a dot (.). To see this folder and its contents, open an Applications > Utilities > Terminal and enter the following in the Terminal window:
cd .lazarus
ls -al
To remove it, execute the following commands in a Terminal:
cd
rm -rfv .lazarus
Third party package uninstaller
If you have installed Lazarus using the official package files, then you can also use a third party uninstaller like UninstallPKG from Core Code. You can perform 5 uninstallations for free before you need to buy it ($US 9.99/Euro 9.99).
