I can't install Roblox studio on my Macbook

I have normal Roblox already installed and working perfectly, but when I try to install studio nothing happens.

I double click the dmg installer, it shows the studio logo then I also double click it to open a window, then I click "open" but nothing happens, I restarted my Macbook countless times, I repeated the process, but again nothing happens when I click to open.

Keep in mind I didn't had this problem with normal Roblox.
