How to Install DVD Photo Slideshow on Mac OS X 10.8 or Later
When you downloaded DVD Photo Slideshow and tried to install it onto your Mac, there may be a pop-up dialog message saying that DVD Photo Slideshow Professional can't be opened because it is from an unidentified developer as shown below.
This is because Mac OS X 10.8 Mountain Lion, 10.9 Mavericks, 10.10 Yosemite, 10.11 EI Capitan and 10.12 Sierra, include new features to improve security for users. One of the new default options prevents users from being able to install applications that are not downloaded from the Mac App Store or that have not been digitally signed by the developers.
To install DVD Photo Slideshow on Mac OS X 10.8 Mountain Lion, 10.9 Mavericks, 10.10 Yosemite, 10.11 EI Capitan and 10.12 Sierra, please follow the steps below:
1. Go to System Preferences -> Security & Privacy
2. Click the lock icon in the lower-left corner and enter your administrator username and password
3. Under "Allow applications downloaded from", select "Anywhere"
Please feel assured that DVD Photo Slideshow for Mac is 100% safe and secure and we will get it digitally signed soon.
