Frequently Asked Questions

Q: Why can’t I open Overture on MacOS Sierra?

Some Mac OS X users are experiencing issues when they try to open a freshly downloaded copy of Overture. Specifically, the error message that is shown says that »“Overture” is damaged and can’t be opened. You should move it to the trash«:

Mac OSX Error

Until we have this issue solved, one possible workaround that enables you to use Overture on your Mac is to download Overture using wget as shown below. Note that the following command downloads Overture version 2.4.6. You may want to adjust this command according to the particular version that you are interested in.

wget https://github.com/overturetool/overture/releases/download/Release/2.4.6/Overture-2.4.6-macosx.cocoa.x86_64.zip

Alternatlvly you can either add a GateKeeper rule like:

spctl --add --label "Overture" /Path/To/Overture
spctl --enable --label "Overture"

Source

or simply disable GateKeeper:

# Disable
sudo spctl --master-disable
# Enable
sudo spctl --master-enable
