During the installation of ACDSee Photo Studio for Mac, you will be asked to provide your Mac's admin password in order to continue. This is not the acdID username and password.

If you want to add another user account to  your mac, you will need that password too.The following example will help you recall that password

- Go to System preferences
- Go to "User & Groups"
- Click the "lock" icon next to the "click the lock to make change" on the bottom left corner
This will prompt you to enter the Mac admin password.

So please use the same admin password to unlock the installation of any programs, including ACDSee for Mac.
