Using Unsigned Software in macOS Catalina

General FAQ
#1

Hi,

In order to use unsigned software in macOS Catalina, the best available option is to run a xattr command in Terminal, and use the -d option to remove com.apple.quarantine as an (extended) attribute.

Here is the command line: xattr -d com.apple.quarantine **filepath**

You can also add the -r option to run the xattr command on a folder or bundle.

Here is the command line: xattr -d -r com.apple.quarantine **filepath**

In the command lines sketched above, you should replace **filepath** with the filepath of the file or folder/bundle of unsigned software, respectively. And you’re set.

Hope this helps.

All the best,
António

Hi Dietmar,

Since you’re having issues with Orchidea, your best bet is to post under the “Orchidea” banner… This post is under the “General” banner.

I do have some experience with Orchidea (0.5, not yet 0.6), but I’m having trouble understanding what you’re asking exactly. Perhaps you could create a topic on the issue you’re having, and if I can answer it appropriately I’ll gladly do so.

All the best,
António
