What is error code 45, and how does it happen?

At times when you are using your Mac as usual, a warning message box might suddenly pop up saying that “The operation can't be completed.An unexpected error occurred (error code 45)”. Troubleshooting that kind of error code could be a tough task if you have no idea what’s happening on your Mac. Error code 45 could happen for a number of reasons, and it may show up with a specific error message:

• LckdErr = -45, /*file is locked*/

The followings are the main causes why your Mac gets error messages:

• Improper operations on the system, application, process or service
• Corrupted system files and directories, misconfigured system settings
• Virus infection, malware or spyware attacks, suspicious file download
• Incompatible or outdated software/hardware installed on the machine
• Junk files filled with the startup drive or current user’s home directory

When you come across the error code 45, there is a general set of troubleshooting steps you can take. Does it happen at regular intervals, or totally random in nature? Does it come out after any changes you made to the system? Is there any app you suspect to be related to this issue?......With these questions in mind, you can do some tests to first verify whether the error is hardware-related, or software-related. Once the root cause of the error are identified, you will be able to fix it successfully by adopting corresponding solutions. Now let’s go straight to figure out what’s going on.

Solutions to fix error code 45 & optimize your Mac:

Here we list several approaches to help you identify and troubleshoot Mac issues. Follow the steps to fix error code 45 and get the tricks to optimize your Mac.

Keep your system and apps up-to-date

Older versions of Mac OS and outdated apps are prone to be attacked by malicious activities. They may also be incompatible with some new features, or insufficient to support certain system operations, and thus drag down your whole Mac performance.

Keeping everything on your Mac updated will not only help the Mac run smoothly, but also lowers the possibility of getting unexpected error, including error code 45. To upgrade your system and apps to the latest version, first go to Apple menu and select App Store. Click on the Updates icon on the top panel, and check the available updates for your system and installed programs. If some apps are not downloaded via the App Store, you will need to check the update manually. For that kind of apps, just launch the app, and access the Software Update option from the Preference settings.

After running all available updates, you can continue to perform a virus scan, to make sure you don’t have any malicious software or virus that are causing problems.

Check login items to troubleshoot error code 45

In some cases, many issues can be resolved by simply rebooting your Mac, and you can move along. But if the problem persists after a reboot, you can restart your Mac into Safe Mode to do a test. If the error code 45 disappears in Safe Mode, there may be an issue with a startup item, login item, or kext file. You might need to check your login items and see if the error code 45 is related to one of the programs loading up automatically on startup. You can narrow down the scope by doing so:

• To clear out your login items, open System Preferences, and select Users & Groups.
• Click your account on the left, and click the Login Items tab on the right.
• Select the items from the list, and click the minus sight to remove them all.
• Reboot your Mac, and see if the error code 45 shows up or not.

If the issue disappears, that means one of your login items is causing the problem. You can try loading up each of them to test which one causes the problem. If you wanna manage startup items more effectively, use a Mac optimizer to save some trouble.

Delete temporary, junk and cache files

Both system and applications create temporary files, preferences, and caches under your current user account. When some of those files are corrupted, problems may occur including system hangs, app crashes, and the inability to perform specific tasks. To further troubleshoot error code 45, you can log into the Guest account to help determine if the issue is account-based or rooted in the system. If error code 45 persists in your Guest user account, the issue is more likely to be system-wide. But if the error disappears in Guest account, it might be an issue with your home folder.

You can try to log in with different user account to see if the error still occurs when you run the same program. Once you eliminate other possible factors, you will get close to the deep cause of the error.

In the cases when an application get corrupted, outdated, or incompatible with other new installed apps, error message could pop up during the usage, You need to repair, update, or reinstall the app to test if that helps. It is also worth visiting the app developer’s website to see if other users are having the same problem you encounter.

Once you have identified the problematic app which gives arise to error code 45, you could perform a clean uninstallation after backing up related data. To uninstall an application on your Mac, locate its icon the Applications folder from Finder, then drag and drop it to the Trash on the Dock, and empty the Trash to start the removal.

Run disk utility to repair disk permissions

Permission issues can often be responsible for many error codes. In the daily use, fixing those permissions is one of the most common way to resolve problems related to files and applications. If problems happen due to improper permissions, you can use Mac’s built-in Disk Utility to check the startup disk for errors and run a full system permissions fix, so as to ensure the system files are properly accessible. You can also reset the permissions on home folder in your user account, to ensure programs, services and anything else under your account has proper permissions.

Fixing permissions in OS X is quite straightforward. If you are running OS X Yosemite or earlier, follow these steps to repair the permissions on your boot drive:
