As discussed in the Security & Privacy Access section, DropDMG needs Automation access in order to fully function.
macOS will automatically ask you when DropDMG needs to be able to control an application. It will show an alert, and you should click the OK button.
If you accidentally click Don’t Allow and deny DropDMG access to control an application, macOS will remember this and may not ask you again. However, you can fix this by manually granting access.
To Grant Automation Access on macOS 13 Ventura Through macOS 14 Sonoma
Go to System Settings ‣ Privacy & Security ‣ Automation. (You can also click here to go directly to Automation.)
Click the switch(es) under DropDMG.
To Grant Automation Access on macOS 10.14 Through macOS 12
Go to System Settings ‣ Security & Privacy ‣ Privacy ‣ Automation. (You can also click here to go directly to Automation.)
Checking the box(es) under DropDMG.
Troubleshooting Automation Access
It may help just to restart your Mac.
You can enter this command in Terminal:
tccutil reset AppleEvents
to reset the system’s database of Automation privileges. Then macOS will ask you again the next time DropDMG needs access, and you can click OK. If it still doesn’t ask you to grant access, it may help to restart your Mac again or use the maintenance feature of Onyx.
If it still doesn’t work, see the Troubleshooting Privacy Access section.
