Dialog after Big Sur Update 9/30/21

A program tried to load new system extension(s) signed by “Kirill Luzanov”. If you want to enable these extensions, open Security & Privacy System Preferences.

I’ve found “Kirill Luzanov” on FaceBook (look like a truck driver!) and GitHub https://github.com/luzanovko.

Unfortunately, many of Apple’s ‘warnings’ are a bit short of useful info. I declined to ‘allow’ "Kirill Luzanov” or his ‘program’ to load/install any “system extensions”. Thank you very much! :rofl: But it would be nice to know who/what/why the dialog displayed after the Safari and “Hardware(?)” update today.

Did you follow the dialog’s instructions and look in the Security & Privacy System Preference? It should show the name of the software for which an extension is trying to install.

I googled “Kirill Luzanov Mac app” (I added the other terms because there’s probably more than one person with that name in the world) and found a listing that suggests they’re a developer for the Mac app DriveDx, is that something you have installed?

The first link in the google search seemed to go to an outdated site (formidapps.com), DriveDx seems to be currently offered by Binary Fruit. Another search result associated their name with a kernel extension for SAT SMART Driver, another program from Binary Fruit.

In further searching I also turned up your findings. I also did check System Prefs-> Security & Privacy / General tab. It includes most warnings related that may appear on the day you see that kind of dialog. However, it is (in this case, anyway) a shortened version of the text in the warning dialog:

Blockquote “System software from developer ‘Krill Luzanov’ was blocked from loading.”

I vaguely remember “DriveDX” and found it installed back in 2019! I have 4 days left on the trial use! :thinking: Doesn’t appear I found much use for it! :crazy_face:

DriveDx is one of a few utilities that is essential in diagnosing a failing drive since Disk Utility won’t notify you until the drive actually fails.

The SATSMART driver is only needed for USB connected external drives. If you only have an internal or your external drives are connected with FireWire or thunderbolt then it does not need to be installed.

This was helpful. I too recently encountered a similar Security & Privacy message, “System software from developer “Kirill Luzanov” has been updated.” I’ve been asking around if anyone knows who the heck this person is… and what he is doing on my Macbook Air M1. This Tidbit exchange answers the question.

I’d also say that, while I’ve had DriveDx installed for several months, it consistently produces “OK” and “Not OK” reports on some of my USB external hard drives. To the point, where I don’t trust it. However, I see that the app has existed for a number of years and is respected in the Mac community. Right now, it is UN-installed on my computer. I’d appreciate hearing more from those that trust DriveDx.

I had Drive DX installed for many years with out problem on an iMac 27". I didn’t reinstall it when I moved to an M1 MBP this year, but have been looking at using it again as I dropped an external back up drive and wanted to check it. Drive DX appears to give quite useful information, however it does require additional access and trust permissions (for the developer Kirill Luzanov) if you want it to scan an external USB drive.
I have declined to give it that permission and realise that it’s a sad sign of the times that it’s the Russian sounding name that makes me suspicious.
