![]() With the quarantine flag removed from the Disk Image, the package inside it installs without trouble. Even VMs are serious about security, and they too block its installation unless you strip the quarantine flag, something readily done in xattred. One potential way ahead is to install the package in a macOS virtual machine (VM). As they may not even use a Mac, let alone one running Ventura, they may be completely unaware of this. What you should really do now is contact the developer and inform them of the problem. Can you be absolutely certain that Disk Image is exactly as its (non-malicious) developer intended? The only way to prove that reliably is by checking the hashes in a signature that can be trusted, and that’s the reason that macOS won’t let you open the package: the developer has failed to provide that assurance. ![]() You should never remove a quarantine flag from anything whose origin isn’t verifiably trustworthy. You can, though, open the Disk Image file with xattred, where you’ll discover a quarantine flag, or extended attribute with the name, and that’s likely to have a value of 0083, which means the flag is still set. Copy it from the mounted Disk Image and try to open it using my free extended attribute utility xattred, for instance, and you just get the same alert informing you that it can’t be opened because macOS can’t verify that it’s free from malware. Whatever you try to do with that Installer package, macOS simply won’t let you inspect it properly. So is this about quarantine flags, and why should that make any difference in Ventura? This time it rubs salt into the wound by reminding you that macOS blocked the Installer app from doing what it should have done. Just as you start cursing under your breath and dismiss that alert, up pops another. Those can only have been obtained from one of two places: the quarantine flag itself, or the macOS quarantine database. The greyed text in the third paragraph gives a good clue what’s going on here, as it reads almost identically to descriptions given of apps being run for the first time with their quarantine flag still set: it names the browser that downloaded the Disk Image, and the time and date of download. Downloaded through its SourceForge site, it arrives as a Disk Image that mounts to provide its Installer package, and that consistently fails to open because of this complaint from macOS. My latest example is smartmontools 7.3, the superb open-source SMART toolkit used by almost every other app that checks the SMART status of disks. This article explains why, and what you can do about it. While the image mounts fine, all attempts to install from that package fail, with macOS reporting that’s because the software comes from an unidentified developer, so macOS can’t verify that it’s free from malware. ![]() These are commonly Installer packages, often delivered in a Disk Image.
