2. Use the Disk Utility and Hardware Diagnostics

Some Mac users, who have reportedly experienced the error -1008f, took their machines to Apple repair centers. Upon getting back their Macs, they were advised to have some of their hardware components replaced. This suggests that the error code -1008F is a hardware problem.

There are two ways to check the quality of your computer’s hardware: using the disk utility tool and performing a hardware diagnostics test.

How to Use the Disk Utility Tool on Your Mac

The disk utility tool can help troubleshoot specific disk problems on your Mac. Examples include when multiple apps quit unexpectedly, when your computer crashes, when external devices don’t work as expected, and when the Mac won’t start up. To launch the Disk Utility tool, take the following steps:

1. Restart your computer by navigating to Apple Menu > Restart.
2. Hold the Command and R keys until you see the Apple logo.
3. Click Disk Utility and continue.
4. Choose View > Show all Devices.
5. Select the disk that you want to troubleshoot.
6. Click the First Aid button and click Run.

After the repair process, the Disk Utility tool will issue reports on how the process went. If the reports state “overlapped extent allocation errors,” it means that two or more files occupy the same space on the disk that you have just tested. It may also indicate that one of them or both are corrupted. If this happens, you might have to delete the affected files.

At times, the Disk Utility tool may fail to repair your disks in which case it will report that “the underlying task reported failure.” When this happens, you might need to format your files, replace the disk or reinstall macOS. Whatever you choose to do, make sure that you back up your data first, so that you can reinstall it later.

How to Use the Apple Hardware Test on Your Mac

Unlike the Disk Utility test, the Apple Hardware test is more comprehensive as it tests all the hardware components on your computer for any malfunction. To perform an Apple Hardware test on your Mac, take the following steps:

1. Disconnect all external devices from your computer, except the mouse, keyboard, display, Ethernet hardware components connection, and the AC power connection.
2. Place your Mac on a flat, hard, and well-ventilated surface.
3. Shut down your Mac.
4. Turn on your Mac and immediately press the D key. Keep holding this key until the Apple Hardware test icon appears.
5. Use the up and down keys or the mouse to select your language preference and hit the Return key.
6. To begin the test, press T. Alternatively, choose the Perform extended testing option. This will do a more comprehensive test than pressing T, but will also take longer to complete.
7. After the tests are done, you can review the test results in the lower-right section of the Window.
8. To quit the test, you can choose to restart or to shut down your computer.

The results of the Apple Hardware test will tell you if there is anything wrong with your computer and if there is, you should take appropriate action.

3. Downgrade from Catalina to Mojave

This is yet another of those undesirable solutions, but which seems to work just fine when it comes to resolving the error -1008F on your Mac. If you are big on Reddit macOS forums, you must have seen that many macOS users recommend downgrading from Catalina to Mojave as a temporary solution to resolving the error -1008F.

Catalina was released in June 2019, and since then, there has not been a lot of time to detect and remove all the bugs that come with any new release. Even Apple has so far not commented on the error code -1008F, which means that they have not figured out all the bugs yet.

When you think about it, going back to Mojave from Catalina is not such a big change, at least it is worth the reduced stress of having to deal with the error code -1008F.

4. Update the Network Adapters on Your Mac

As noted earlier, the error -1008F is experienced when trying to complete the internet recovery process. And if this is indicative of anything, it is that outdated network drivers are likely to blame.

Updating your computer to the latest driver versions is easy on a Mac. This is because Apple handles all system and hardware updates for your computer. You can check if there are any updates available by clicking on the Apple icon in the left corner of the screen and selecting “Software Update.” If there are any software updates, they will be listed. On the other hand, if everything is up-to-date, you will also be notified.

After making the updates, check to see if you are still experiencing the error code -1008F. If so, then it is time that you tried this last option.

5. Visit a Mac Repair Clinic

All Apple products come with a warranty of a few years, and if your computer keeps on malfunctioning, then it is time that you visit an Apple repair clinic and have it checked. Some users have reported getting new keyboards and other hardware components, such as a new logic board.

Remember that the error code -1008F could be a result of a faulty hardware component, and if this is the case, only Apple can come to your rescue. They seem to have a very responsive and helpful customer care team, don’t hesitate to take advantage of them.
