I tried to install the Arduino Create Agent but it wouldn’t let me. I got this error code:

“ArduinoCreateAgent-1.1-osx-installer-CC” can’t be opened because Apple cannot check it for malicious software.”

What should I do
I am using a Mac OS 10.15.2 on a Macbook Air

hi @Shifty_Lola

Mac OS Catalina has a more aggressive check on how an application is registered with Apple (Notarised).
We're in the process of finalising this process for good, but right now you'll have to use a work-around to install.

Right click (or CTRL + Click) on the icon and select "Open".
This should ask you if you are sure you want to install. Agree and the process will continue.

Sorry for the inconvenience, but Apple sometimes tries (for good reason) to make things harder to protect non advanced users.

If it doesn't work out let me know and I'll test further :slight_smile:


Update: I'm happy to report that a new notarized version of Arduino Create Agent (1.1.251) has now been released. This will no longer require the workaround described above. You can get it here:
