Hi all

I am using LiveCode Create in classic mode and an old stack. When I try to create a standalone (Mac, Linux) I get the following message (with directory redacted). Any ideas pls?

@Kaveh: I've tried locally and cannot reproduce this problem - however, we think we've seen a similar error reported before if you try and build a standalone into a folder which is enabled for iCloud sync? Is that the case here?

Yup. That was it. Everyone on my mac is synched to Icloud, except a folder that is on Google Drive. I selected the latter and it worked. Thanks.

@kaveh1000: So I suspect there is nothing wrong with the standalone - its just that Apple doesn't let apps which aren't signed properly (using a certificate from an Apple developer account), or notarized open directly on other machines. (The S/B signs apps with an 'ad hoc' signature so that they will open on the machine they were built on).

Depending on the version of the OS, right-clicking and selecting 'Open' might work (that might require a tweak to GateKeeper settings, I think).

Alternatively, you can ad-hoc sign the app locally from the terminal (on the target machine). Something along the lines of:
