You have to approve the installation of the driver via macOS’s Security & Privacy preference pane, and typically restart your Mac to have the data become available.Īs with any third-party driver, you should be alert to whether you see any odd system behavior after installation that might indicate compatibility problems with other software or macOS. data as Apple doesn’t provide another path, according to the developer. A hardware driver is rare for any modern Mac software, but necessary to access the S.M.A.R.T. To use DriveDx with external drives, you have to install an included driver. While most modern Macs can’t have their SSDs swapped out, at least you’d be able to be forewarned as the potential end of life approached. However, some users find their particular data patterns put more pressure on SSD writing, and may have just a few years left on a relatively new machine. If this keeps up, the drive should far outlast my Mac. In my iMac’s nearly two years of use with a 28GB SSD and a 1TB HDD, DriveDx calculates that it’s already gone through 10 percent of its expected lifetime. It also monitors available free space to alert you before a drive is full. You can also configure email alerts, if it’s running and you’re away from your Mac. If you’re actively concerned about drive health, the app can be kept running in the background, and a system menu bar item reveals current drive health status. This can be as severe as “there is a high probability that drive will fail soon,” along with advice like “Backup your data immediately!” IDGĭriveDx details the severe efforts on a failing external drive. If there are errors that need to be addressed or the drive is failing, the software summarizes the problems and offers a Diagnosis button that, when clicked, explains each error and how bad it is. You can also find out some peculiar and interesting data points, like how often a drive has been powered up and down (whether an internal drive that might be powered down to preserve battery life or an external one you switch on or off), Health status The label or status on nearly every item can be clicked to bring up detailed information about the property. though I consider it quite rude for an application to write to another application's plist file that way, I don't see a realistic way that this specific instance harms your system.DriveDx presents other information it gathers or the results of its analysis in a similar fashion. One of the files in that list is highly unusual for an application to read, and it's reading it in this case because it's written something there already.Īnd just to be doubly clear about this particular case. Select "Reads/Writes" and, if necessary add a filter string at the bottom to narrow down the files you see. Launch instruments and select the File Activity template.Ĭhoose the executable you want to monitor and accept the default settings.Ĭlick the red "Record" button to launch the application and monitor its activity. I'll show you how to see just what an app is doing to your files, because this is an important skill IMO. I certainly won't be installing it again. I highly doubt that anybody here has the intention to use such information to extend their trial periods indefinitely. I don't think it's unethical to just show what the heck the app is doing. So it's storing that info somewhere else.and what's even odder is that I used an app uninstaller to delete it, so whatever file it left behind wasn't detected by them. Incidentally, deleting AppDelete's plist file doesn't reset the trial. In principle you might sleuth this out using lsof to see which files are touched while AppDelete starts up. In other words, a file which looks "official" and won't interfere with system functionality, but only AppDelete knows the name and location. It might be stored in something tricky like ~/Library/Application Support/AddressBook/Metadata/C433D242-DB05-4894-A387-EC5B1B62A540/ABPerson In which case you may never find the file where this data is stored. That being said, the forever war of scummy users vs scummy developers results in this data being written into odd places with unpredictable names. Well behaved apps which trust their potential customers will store this information in a plist in ~/Library/Preferences.ĪppDelete, for example, might store this info in the file:
