I tried running a 2nd instance of Roblox simultaneously on macos 15 with another account but this shows up, if my mac can handle it then why can’t it just let me do it? If I have two copies of an app like Roblox in separate User/Applications folders, macos moves them to the /Applications/ folder.
Sometimes it won’t run apps claiming to be corrupted, so I then have to do sudo xattr -cr /Applications/someapp.app in the terminal and they run perfectly fine. It always nags me if I download apps from anywhere but mac app store. Some of these messages can only be gotten rid of by disabling system integrity protection, but then macos blocks you from running MAS apps due to having “permissive security”.
I don’t daily drive macOS anymore, I switched to Linux on my M1 mac where I can do whatever the hell I want.
While the app running permissions of macOS have become extremely obnoxious, you don’t need to disable system integrity protection. After macOS refuses to open an application, open system preferences -> security and there will be a button that says „open app anyway“, which you then confirm via password or fingerprint.
My memory is probably hazy (it’s been a while since I used macOS) or it might’ve been removed but I recall that you were able to hold a key on the keyboard to bypass it as well. You’d have to right click the application, then hold down the key, and while holding it down click “Open”.
Said key I believe was the “option” key
It’s an extra step in macOS 15. You need to go into System Settings now.
Used to just be able to use the contextual menu to open it and get an approval dialog.
Ah gotcha, that’s a bit unfortunate - good to know though!
