I cant install pkg. file
Hello people, I have a pkg. file but I cant install it. Every time I click it I get "The operation couldn’t be completed. (com.apple.installer.pagecontroller error -1.)" error. Permissions are all set so there is no problem. And I tried creating a disk in disk utility and tried running the installation from there as I saw it in one of the responses but it didnt work too. How can I install it? Please help me guys. Thank you.
