Q100190: Installation issues of The Foundry products on Mac OS Sierra

Follow

SUMMARY

Installing The Foundry products in Mac OS Sierra will raise an installation warning as we are not an identified developer.

MORE INFORMATION

Currently many The Foundry products will receive an installation warning when installing on OS Sierra. In previous OS versions you could navigate to the Security & privacy section in the preferences and set 'Allow apps to be download from: Anywhere', which would remove any future installation warnings. 

This feature has been removed from Sierra and as such we wanted to highlight current known workarounds for installation. Apple currently offers the following advice:

If you try to open an app that is not registered with Apple by an identified developer you get a warning dialog. This doesn’t necessarily mean that something’s wrong with the app. For example, some apps were written before developer ID registration began. However, the app has not been reviewed, and macOS can’t check whether the app has been modified or broken since it was released.

A common way to distribute malware is to take an innocent app and insert harmful code into it, and then redistribute the infected app.

The safest approach is to look for a later version of the app from the Mac App Store or look for an alternative app.

To override your security settings and open the app anyway:

In the Finder, locate the app you want to open.

Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.

Control-click the app icon, then choose Open from the shortcut menu.

Click Open.

The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.

Note: You can also grant an exception for a blocked app by clicking the “Open Anyway” button in the General pane of Security & Privacy preferences. This button is available for about an hour after you try to open the app.

To open this pane, choose Apple menu > System Preferences, click Security & Privacy, then click General.

Open the General pane for me

To change your security settings, see Protect your Mac from malware.


Another workflow raised by The Foundry customers is to run the following in a shell:
sudo spctl --master-disable
