Deploying Grammarly for Mac Using JAMF (Script Method)

Step 1: Prepare a script.

1. Log in to the Jamf instance and navigate to Computers → Computer Management → Scripts.
2. Click the +New button in the top-right corner.
3. Fill in the Display Name and assign the category in the General tab.
4. Go to the Script tab, copy-paste the script below, and click the Save button.

#!/bin/sh
currentUser=$(ls -l /dev/console | awk '{ print $3 }')
dmgfile="Grammarly.dmg"
volname="Grammarly"
/bin/echo "--"
# check if logged in user has admin rights
IsUserAdmin=$(id -G $currentUser| grep -v 80)
if [ -n "$IsUserAdmin" ]; then
grammarly_dir="/Users/${currentUser}/Applications"
    /bin/echo "`date`: $currentUser is not local admin"
else
grammarly_dir="/Applications"
    /bin/echo "`date`: $currentUser is a local admin"
fi
# check if Applications folder exists
if [ -d "$grammarly_dir" ]; then
echo "Application folder exists"
else
echo "Application folder doesn't exist"
mkdir "$grammarly_dir"
    chown -R "$currentUser":staff "${grammarly_dir}"
fi
# check Download link and availability of Grammarly CDN
if [ -z "$4" ]; then
    url='https://download-mac.grammarly.com/Grammarly.dmg'
    /bin/echo "No arguments supplied. Using default address"
else
    url=$4
fi
/usr/bin/curl -f -s -I $url &>/dev/null
if [[ $? -eq 0 ]]; then
    /bin/echo "`date`: Grammarly Desktop download site ${url} is available."
else
    /bin/echo "`date`: Grammarly Desktop download site ${url} is NOT available."
    exit 1
fi
/bin/echo "`date`: Checking and unmounting existing installer disk image"
/usr/bin/hdiutil detach $(/bin/df | /usr/bin/grep "${volname}" | awk '{print $1}') -quiet
/bin/sleep 10
/bin/echo "`date`: Downloading latest version"
/usr/bin/curl -s -o /tmp/${dmgfile} ${url}
/bin/echo "`date`: Mounting installer disk image"
/usr/bin/hdiutil attach /tmp/${dmgfile} -nobrowse -quiet
/bin/echo "`date`: Installing..."
/bin/echo "${grammarly_dir}/Grammarly Desktop.app"
/usr/bin/sudo -u "$currentUser" cp -R "/Volumes/${volname}/Grammarly Installer.app" "${grammarly_dir}/Grammarly Desktop.app"
/usr/sbin/chown -R "$currentUser":staff "${grammarly_dir}/Grammarly Desktop.app"
xattr -r -d com.apple.quarantine "${grammarly_dir}/Grammarly Desktop.app"
/bin/sleep 10
/bin/echo "`date`: Unmounting installer disk image"
/usr/bin/hdiutil detach $(/bin/df | /usr/bin/grep "${volname}" | awk '{print $1}') -quiet
/bin/sleep 10
/bin/echo "`date`: Deleting disk image"
/bin/rm /tmp/"${dmgfile}"
/bin/echo "`date`: Setting onboarding deferral"
/usr/bin/sudo -u ${currentUser} defaults write com.grammarly.ProjectLlama deferOnboarding -bool YES
/bin/echo "`date`: Running the app"
/usr/bin/sudo -u ${currentUser} open "${grammarly_dir}/Grammarly Desktop.app" --args launchSourceInstaller
exit 0

Step 2: Create the Configuration profile to allow Grammarly for Mac to access the Accessibility.

1. Navigate to Computers → Configuration Profiles and click the +New button in the top-right corner.
2. Fill in the General tab:

   • Choose a Category according to your organization’s settings.
   • Ensure that the level at which to apply the profile is Computer Level.
   • Choose the desired Distribution Method:
     • Select Install Automatically to push profile to scoped computers immediately.
     • Alternatively, select Make Available in the Self Service to let users install it on their own:
3. Navigate to the Privacy Preferences Policy Control and click Configure. Fill in the following:
   • Identifier: com.grammarly.ProjectLlama
   • Identifier Type: Bundle ID
   • Code Requirement:
     

     anchor apple generic and identifier "com.grammarly.ProjectLlama" and (certificate leaf[field.1.2.840.113635.100.6.1.9] /* exists */ or certificate 1[field.1.2.840.113635.100.6.2.6] /* exists */ and certificate leaf[field.1.2.840.113635.100.6.1.13] /* exists */ and certificate leaf[subject.OU] = W8F64X92K3)

   • Check the Validate the Static Code requirement box.
   • Click the Add button and select Accessibility in the App or Service dropdown menu.
   • Select Allow from the Access dropdown menu:
4. Navigate to the Scope tab and set the Deployment Targets, Limitation, and Exclusions.
5. Once the Privacy Preferences Policy Control and the Scope are defined, click Save to begin the profile enrollment.

Note: In order to avoid the Accessibility prompt in the app, the configuration profile should be installed before the application is installed.

Step 3: Create and apply the Policy with script.

1. Navigate to Computers → Policies and click the +New button in the top-right corner.
2. Under the General tab in the New Policy:
   • Enter the policy name.
   • Select the trigger option according to your organization’s settings:
     • Check the box near the Recurring check-in option to enroll this policy on all scoped computers during the next sync with the Jamf server.
     • Alternatively, check Enrollment complete to trigger the policy immediately after a computer completes the enrollment process.
     • Check Custom to set up your custom trigger.
     • Leave all trigger options unchecked for the installation from the Self Service
   • Select the Execution Frequency depending on your Jamf organization setting:
     • Select Once per computer from the dropdown menu for initial enrollment.
     • Alternatively, select Ongoing for the installation from the Self Service.
   • Adjust other fields under the General tab such as Category, Server-side, or Client-side limitations according to your Jamf organization settings:
3. Navigate to Scripts and click Configure.
4. Choose the Grammarly Desktop script from the list.
5. Optional: Adjust Maintenance tab to Update Inventory after the policy installation.
6. Set the Deployment Targets, Limitation, and Exclusions under the Scope tab.

   • Check the Make the policy available in Self Service box
   • Fill in the Self Service Display name, Button Name, and Description. Choose the Category according to your organization’s settings. 
   • You can find the app icon for the Self Service here: Grammarly Icon

Once you complete all the required fields, click the Save button to start the policy enrollment.
