Hp Utility Download It TodayChoose the best app and download it today for free. Code signing and certificatesMacUpdate's software library contains more than 57 Printers apps designed for Mac owners. This is a story of those keys, and how a Hewlett Packard (HP) error caused problems for a lot of people.![]() ![]() Your software will also probably just get deleted by many people.This obviously applies to apps you download from the Internet or the App Store, but it also applies to more prosaic software, such as print drivers. As a developer, if you don’t sign your Mac software, your users will have trouble running it, and you (or your support staff) will get countless help inquiries. This allows the system, and the user, to verify which developer created the software, and check that it hasn’t been modified since it was created.In recent years, Apple has done more than just support code signing… it’s come as close as is reasonably possible to requiring code signing. Code signing involves using a certificate to cryptographically sign a piece of software. For quite a few years now, Apple has supported what is called “code signing” on macOS. Not many people actually look at these certificates, of course, but doing so is a sure-fire way to avoid a phishing site.How does this relate to Apple and HP, you ask? Good question. At least, that’s what they were saying. So, what happened?Last Thursday evening (October 22), we started seeing an influx of support requests from people complaining about some new malware that we weren’t detecting. The certificates used by HP are no exception. Why did macOS think it was malicious?Initially, there was a lot of finger pointing at a recent XProtect update. Samples of the software that we obtained appeared to be legitimate, with no signs of malicious behavior. The messages generally appeared when people were trying to print to their HP printers. However, it turned out, according to a statement from HP given to The Register, that HP itself had erroneously requested that the certificate be revoked.We unintentionally revoked credentials on some older versions of Mac drivers. It was initially assumed that Apple had erroneously revoked the certificate. With some digging, we found that the source of the issue was that the developer certificate used to sign these HP drivers had been revoked.Revoking a certificate is usually done by Apple when a piece of malware is discovered to be signed using that certificate. Descargar driver controladora de bus serie universal usb windows 7As an example, there was a case back in August where a developer named Charlie Monroe reported that his entire Apple developer account was deleted, and his code signing certificate was revoked. The impact of false positivesThis isn’t the first time that certificates have been revoked in error. We’re still seeing new cases reported days later. In the meantime, we recommend users experiencing this problem to uninstall the HP driver and use the native AirPrint driver to print to their printer.Apple was able to reinstate the revoked certificate, which fixed the problem for some people, but not everyone. I don’t know how Charlie Monroe is doing, but I suspect that a significant number of people who were using his software probably deleted it, and may never trust his software again.At companies like Malwarebytes, these events have the potential to result in hundreds or thousands of support tickets from customers asking why we didn’t detect this “malware,” or even why we’re blocking something legitimate (on the mistaken belief that this message is being shown by Malwarebytes). However, when there’s a certificate issue with a piece of Mac software, it affects everyone, everywhere, who is using that software.The fallout of these events can hit the developers hard. Mistakes happen, and Apple isn’t always to blame in cases like this. ![]() This led to a lot of speculation and finger pointing at Apple (in which yours truly regretfully participated), but this appears to have been an unrelated and coincidentally timed issue. There was another issue with a couple Amazon apps – Amazon Music and Amazon Workspaces – where users were seeing the same behavior. How to fix the Mac/HP printer issueIf you are among those who are still having the problem, here are some possible fixes that have worked for our customers:1) Restart your computer, ensuring it’s on the network when it restarts2) Check for HP software updates via the Software Update pane in System Preferences3) Remove the HP printer from System Preferences -> Printers & Scanners, then try adding it again.4) Check for newer HP software for your printer on the HP support site:5) If all else fails, contact HP via its support site for assistance.Earlier, we said that the issue was mostly related to HP printer drivers. Don’t automatically believe that something is malware just because you Googled it and found sites calling it malware.
