Imovie Won't Download
So I recently wanted to get imovie for my mac so I went into the App Store to download imovie, but it won't download. When I tree to download imovie, there would be the usual circle that spins to show that it's loading? But it doesn't stop, it just keeps spinning, it doesn't seem to be downloading anything, nothing. So I tried stoping it, then quit the App Store then restart my Mac. When I try to download imovie again, it started to download, and there's the progress circle thing. When I go into my Launchpad, it always stop downloading at around 500 MB. It just stops downloading, disappears, then I need to go back to the App Store and yet again, it keeps on happening. So I need help with this. I'm using MacOS Mojave version 10.14.5. I thought I needed an update but it says I'm up to date. I did try to install Sierria but it says it's not available or something.
