This warning message might also appear when the Gate-
keeper setting is something other than "Allow applications
downloaded from: the Mac App Store."
The following security warning might be shown: "ModelMix-
er_Installer.pkg" can't be opened because it was not down-
loaded from the Mac App Store.
In this case, copy the file from the folder where it is to the
desktop or another folder, and then open it. Alternatively,
change the Gatekeeper settings to "Allow apps downloaded
from: App Store and identified developers" and try opening it
again.
When the Gatekeeper setting is "Allow ap-
plications downloaded from: the Mac App
Store"
"'TASCAM_MODEL MIXER_Installer_x.xx.dmg' is an application
downloaded from the Internet. Are you sure you want to open
it?" might appear as a security warning message. In this case,
click the "Open" button.
Changing the Gatekeeper setting
The Gatekeeper setting can be changed using the "Allow
applications downloaded from:" item on the "General" page
of the "Security & Privacy" pane of the System Preferences.
To change this, you must click the lock icon ( ) at the bottom
left and enter a password to unlock the settings.
This setting will lock again when you close the System Pref-
erences by clicking the button or typing command-Q, for
example, or when you click "Show All" to close the open pane.
ATTENTION
Changing the Gatekeeper settings could result in security
risks.
If you changed the Gatekeeper setting to decrease security
(use one of the lower settings), set it back to the original
setting after updating the driver and/or firmware.
