Android build support pkg is failing to install

I’m using a Mac. and when i download my android build support pkg, and when i try to install it on my mac it shows an “Install failed”. alt text

I downloaded the package from the build settings on unity 3 times and it didn’t work.
So i searched the web for answers i found one saying to download the build support from the Installs > Add Modules on Unity Hub.
When done, i opened Unity form the Unity Hub and now i can use the Android Build. But when i build a project, it tells me to locate the Android Build SDK file so i finish the build, but i can’t locate the file since i used Unity Hub Add Module to Install the Build Support.

So i hope someone can help me build my game for Android, and locate the file or fixing the installation error, etc.

i have same problem and still searching issue
