TASCAM SS250 CONTROL
Working with Gatekeeper
When using Mac OS X, depending on the Gatekeeper security
function setting, a warning message might appear during instal-
lation.
The solution depends on the warning message shown.
See the following explanations for details.
When the Gatekeeper setting is “Allow applications down-
loaded from: the Mac App Store”
The following security warning might be shown: “TASCAM_
SS250 CONTROL.pkg” can’t be opened because it was not
downloaded from the Mac App Store.”
In this case, click the “
OK
” button to close the message. Then,
control-click (or right-click) the file and click “
Open
”.
When the “
‘TASCAM_SS250 CONTROL.pkg’ can’t be opened
because it was not downloaded from the Mac App Store. Are
you sure you want to open it?
” security warning message ap-
pears, click the “
Open
” button.
This warning message might also appear when the Gate-
keeper setting is something other than “
Allow applications
downloaded from: Mac App Store.
”
The following security warning might be shown: “TASCAM_
SS250 CONTROL.pkg” can’t be opened because it was not
downloaded 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.
Changing the Gatekeeper setting
The Gatekeeper setting can be changed using the “
Allow
apps 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 click the button or
type command-Q to close the System Preferences or when
you click “Show All” to close the open pane.
CAUTION
Changing the Gatekeeper setting 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 set-
ting after installing the application.
