A kernel panic is an unpleasant experience for iMac users who encounter it for the first time. It is usually manifested in a black screen, which is not very reassuring, and a message prompting a user to restart their computer. In such cases, the log file contains a long-winded error message detailing the cause of the issue.
Although a kernel panic sounds eerie, it shouldn’t be a reason for trepidation of Mac owners. In the majority of cases, such errors are transitory, which is why your Mac is likely to emerge unscathed from the black screen trap. Furthermore, the occurrence of a kernel panic is not necessarily as a sign of a major hardware problem. In fact, it might be precipitated by something as innocent as a malfunction in a corrupted data package. However, if a user experiences multiple kernel panics, it’s a sign that something has gone wrong with their system.
This piece outlines main cases of the issue and suggests several methods of resolving it.
Causes of a Kernel Panic on iMac Pro
Just like any other computer produced by Apple, or any other manufacturer for that matter, iMac Pro can experience software conflicts incompatible with its normal functioning. Hardware issues can also trigger a kernel panic; however, such issues are less common. Here is a short list of main causes of a kernel panic:
- Lack of RAM;
- Conflicting or corrupted apps;
- Outdated drivers;
- Broken disk permissions.
For starters, it is necessary to determine whether some piece of peripheral equipment causes the incompatibility issue, which results in a kernel panic. To this end, disconnect every device plugged into the iMac Pro one by one and restart the computer each time. Although it is somewhat time-consuming, the cyclic approach will allow isolating the cause of the problem. If it doesn’t produce satisfactory results, it’s time to run Apple Diagnostics. After all external devices have been disconnected from the computer, shut it down. Then, turn it back on while holding the D key. After several minutes, the utility will show the list of detected issues and suggest possible resolution approaches.
The go-to solution for reoccurring kernel panics is to update Mac software. This can be effectively done in App Store. Just go to the store and use the Update buttons to get the latest updates.
Another fix involves disabling login items and starting the iMac Pro in the Safe Boot mode. It can be done in the Users & Groups preference pane. After login items have been turned off, start the iMac Pro normally. If the problem does not present itself again, add login items one at a time to isolate the causal agent of kernel panics. It is necessary to reboot the computer after the addition of a new item.
If a kernel panic is precipitated by a certain app, there’s no need to look for other causes of the issue. In such a case, update the troublesome app and reboot the iMac Pro. If, however, there are no updates to the app, remove it and then reinstall it from scratch.
The last resort is to reinstall macOS. It has to be kept in mind that prior to reinstalling the OS, it is necessary to back up the computer, thereby preventing the loss of important data.
