I'm trying to install the Mono MDK, and downloaded the .pkg for 4.2.1 (about 200 MB), when I double click on the package, it opens a "verifying xxxxxMDKxxxxx.pkg" window, which does nothing for over an hour while the Installer icon bounces on the dock. Is there a way to bypass the verification or force it to verify? Or, alternatively is there a way to install the Mono MDK using the command line? I'm running a early 2011 Macbook Pro on OSX 10.11
Ran into this with some other software, but wanted to pass on a tip I picked up.
In finder, launch
/System/Library/CoreServices/Installer.app. It will prompt you to locate a
.pkg file to install. Navigate to the
.dmg volume you've mounted, and select the
Installation should proceed normally from there.
Not a verified answer but I can't comment: try to disable Rootless System Integrity as indicated here.
Source: OSXDaily says "Mac users may need to disable rootless SIP protection in OS X before being able to successfully install Java, but you can enable it again after it has been installed. If you get stuck on “verifying…” during the installation process of Java, it’s because of rootless."
This might help
That video worked for me, at least.
