1- Download the current DSClient for MacOS (latest version 1.5.5) from here.

IMPORTANT NOTE 1: For users with DSClient versions earlier than 1.5.5, in order for them to e-sign without any issues, users need to either update to 1.5.5, or follow the provided steps in https://faq.cc.metu.edu.tr/tr/sss/ebys-dsclient-lisans-dosyasi-degisikligi to change the license file.

IMPORTANT NOTE 2: The usage of the DSClient application on Safari browser has issues, and the firm is currently working on these issues. For MacOS users to not have any issues while using DSClient, it is advised for them to use browsers other than Safari.

2- Click the downloaded compressed file and open it.

3- Click the folder and access the installation files.

4- Open the Terminal after accessing the installation files.

5- After typing "sh" and a space after it in the Terminal, drag the file named "DSClientMac.sh" to the Terminal. Press enter, then type your user password and press enter again. If it continues in a new line without any errors as shown in the picture below, the installation is complete.

Uninstallation Process

If you want to uninstall the DSClient application from your computer, run these two commands in the Terminal:

sudo launchctl stop com.dsclient.bms

sudo launchctl unload /Library/LaunchDaemons/com.dsclient.bms.plist
