Running ISA tools in Mountain Lion, Maverick, or Yosemite
Since Mountain Lion came out, we’ve had some users unable to run ISA tools. The reason why is down to Apple’s change in security policies. Apple now try to restrict the applications run by default on Mac OS to those downloaded from the app store.
To change this, you need to access your security preferences. You can access this quickly through spotlight as shown below.
You will then be faced with the security and privacy window and will see a section named “Allow applications downloaded from”. You need to change this from Mac App Store to Anywhere. If you are unable to change it, you first need to click on the lock icon to change it. In the end, your Security and Privacy screen should look like this.
Apologies for any inconvenience caused. If you have any further queries, please email us at firstname.lastname@example.org
The ISA team.
