Mac not opening .pkg files
I've recently downloaded the free Office 365 Education and I tried opening the file downloaded, which is a .pkg file. But nothing is opened. When I double-click on the file, a download icon shows on the Dock then disappears. I mean, this is from Office so surely it wouldn't contain malware or something. I've also tried in the past to open downloaded files but they always turn out this way. :c
