6 Common macOS Errors and How To Fix Them

Macs are reliable computers, but you should not expect perfection performance-wise. There are instances when you will notice errors.

These warning messages are not common, but they occur nonetheless. Knowing what to expect and how to counter them will come a long way in improving your overall experience using a MacBook.

Let’s start with the most common errors first and then cover the potential troubleshooting methods.

6 Common macOS Errors and Fixes to Them

#1 – Error 2003f

The 2003f error code is something you see when the computer cannot update the operating system.

As a rule of thumb, you want macOS to have the latest version for general performance improvements and the latest features.

However, if the device cannot install an update, expect to see the aforementioned error message.

#2 – Error 43

Error 43 is another example of an error message that Mac owners encounter. The problem is relatively rare, particularly on newer macOS versions, but you can still see it now and then.

What is error code 43 Mac displays? Well, in layman’s terms, the issue manifests when the system cannot recognize a file you wish to move from one location to another. For example, between two folders or in the Trash Bin.

Some likely causes behind this specific error message are issues related to the MacBook’s hard drive. If you are downloading the file and want to modify it before the download finishes, the error message is likely to appear as well.

#3 – Error 36

Error 36 is related to Finder. If this built-in macOS tool cannot copy or move files, the system will show you the error 36 warning.

It can be tricky to pinpoint the exact cause behind this specific error. For the most part, you can guess that it is the invisible .DS_Store files causing you problems, and you are going to be right 9 out of 10 times.

As far as specific solutions to this error go, your best bet is to open the Terminal and delete the .DS_Store files, which is the first step.

The second step is to then open the folder via the Terminal containing the data that causes the error and hit the Return key. Doing so should merge the data and eliminate the .DS_Store files, letting you modify the files.

#4 – Error 50

Error 50 is another possible error that might happen when you cannot move files. Except in this case, the data transfer is happening from an external storage accessory, such as an HDD or a memory card.

Compatibility issues between the accessory and MacBook, missing firmware updates, and potentially corrupted data are the most common causes behind error 50.

#5 – Error 41

Error 41 with warnings about the lack of memory or how a file cannot load. Treat it as a warning sign that the MacBook’s hardware or software is out of date.

At the same time, do not discard the possibility that the error is related to data that was corrupted by malware.

#6 – 8003

Error 8003 appears when you attempt to delete files in the Trash Bin, but the system prevents you from completing the action.

One of the best solutions to this error is to force-delete items in the Trash Bin. Holding down the Option key and clicking on the Empty Trash button simultaneously is a way to circumvent the problem and get rid of those unwanted files in the Trash.

Basic Solutions to MacBook Errors

While specific errors require specific troubleshooting methods, there are basic solutions that can be tried universally, regardless of what the error is.

1. Scanning for Malware

Use antivirus software to scan the MacBook for malware. Corrupted files are known to create all kinds of problems, including warning messages and errors.

2. Quitting Background Apps

Too much clutter in the background consumes system resources. Open Activity Monitor and find out which of the applications are running.

If an app is redundant, force-quit it. It is possible that you forgot about closing the app after using it or have too many login items that launch with the computer and disappear from your sight.

3. Restart the Computer

A quick restart gives the MacBook a clean slate. It is recommended to restart your computer every few hours or so, especially if the model is not that new.

4. Check for macOS Updates

Make sure that the Mac is up to date. Missing updates means missing performance upgrades and other features, which is bound to affect the computer’s stability.

5. Free Up Space

Check the hard drive’s state. If the total available storage is too low, think about what you can remove. The drive should have at least 15 percent of its total space free.
