Not content with playing havoc with USB hubs in some scenarios, it appears the latest update for macOS Sonoma is also a troublemaker for printers, too.
Indeed, according to various reports online as flagged up by Apple Insider, the macOS Sonoma 14.4 update is breaking printers in some cases. In other cases, there appears to be a more limited impact, in that the printer still works, but selecting page sizes doesn’t.
It seems Sonoma 14.4 is either stripping out, or messing up, printer drivers in Apple’s operating system, rendering the devices non-functional, at least for the time being in many of these reported cases.
There are users complaining about printer functionality going very wonky on Reddit and Apple’s support forums – however, there does appear to be a solution.
Namely, as stated in the above Apple post, you need to head to System Settings, and ‘Privacy & Security’ and then ‘Full Disk Access’ to grant full disk access to ‘com.microsoft.dlp’ – and that might sort the issue.
This isn’t guaranteed, mind, but there are a number of users giving the thumbs-up and saying this move did get their printer (or printers) working in macOS again.
Analysis: A cocktail of possible causes?
Seemingly the issue pertains to Microsoft Defender (which is what the above disk access change relates to), and/or JAMF mobile device management software, and possibly some other factors. It’s difficult to know exactly what, but the most prominent commonality seems to be Defender.
The good news is that this doesn’t seem to be affecting too many macOS Sonoma 14.4 users, as while there are a number of reports, they aren’t too widespread. And they appear to relate to particular configurations, too, mainly in office scenarios.
Given that, hopefully your average user at home isn’t seeing this problem – or only in rare cases. In short, you’re probably pretty unlucky if you hit this snag outside of a business network setting – but it seems that there are isolated incidents of this occuring with individual Macs.
