Julia won't open after updating MacOS "julia” can’t be opened because Julia is not allowed.."

General Usage

Hi all,
I’m using MacBook and after the last update (Sequoia 15.3.1) when I try to open Julia I get the error:
" “julia” can’t be opened because Julia is not allowed to open documents in Terminal."

I believe this is related to security permissions, but I haven’t been able to find a solution.
Has anyone else encountered this issue and managed to resolve it?

Thank you!

How did you install Julia?

If you use juliaup there is a good chance to get a signed version of Julia that is accepted by your OS.

I downloaded the .dmg file for MacOS from here:
https://julialang.org/downloads/

Can you please explain more what do you mean by juliaup?

But a .dmg file from the link you shared should also be fine. juliaup makes it easier to quickly switch Julia versions, so it would be easier to check if a different version perhaps does not have this problem.

Not sure if this tip will help in this particular circumstance, but…

When you get an error message from macOS related to security permissions, if you immediately open “System Settings…”, go to the “Privacy & Security” preference pane, and scroll down to the section that says “Security”, there will often be a message there mirroring the error you just got with a button you can click to grant the needed permissions.

I have macOS 15.3.1, and have no problems with Julia and security permissions.

Generally, the preferred way to install Julia is juliaup.

I’d advise to remove Julia you have installed, and install it anew via juliaup. Most probably, it’d solve your problem.
