How to Delete System Preference Files on Mac OS X | The Hard Way

How to find system preferences on a Mac? All preference files are stored in /Library/Preferences. Usually they named in this manner:com…plist

Now, if you have an application that works incorrectly, you can find the corresponding preference file in the above-mentioned folder and remove it from there. On the next launch of the application, it will recreate a default version of that file and then begin working properly. However, if this doesn’t happen, that it may be a good decision to put the broken preference file back — They can be a bit temperamental. It’s highly advised that you make a copy of the preference file before you delete it, just in case something goes wrong.

So, to remove unnecessary system preferences (or preference files that are bugging your your application), check the:/Library/Preferences

…system folder. To do this, open a Finder window, press Cmd+Shift+G and type the above in. However, be aware that items stored in that location could be incredibly important to your system and how it functions, so you should be 100% sure about the files you’re going to delete.

But again, we’d recommend looking into CleanMyMac X — it makes fixing and removing broken preference files on your Mac easy as can be.

We hope this article has helped you understand what Mac system preferences are, and how to delete system preference files on Mac.

Vorgehensweise für das Löschen einer Festplatte

Befolge je nach Bedarf die Anweisungen zum Löschen eines oder eines . Das Startvolume ist das Laufwerk bzw. das Volume, von dem der Mac gestartet wird. Standardmäßig handelt es sich dabei um das Laufwerk, das in den Mac eingebaut ist. Es trägt die Bezeichnung “Macintosh HD”. Falls du deinen Mac verkaufst, weitergibst oder in Zahlung gibst, solltest du dein Startvolume löschen.

Startvolume löschen

Starte den Computer aus der macOS-Wiederherstellung.
Wähle in der macOS-Wiederherstellung im Fenster “Dienstprogramme” das Festplattendienstprogramm aus. Klicke anschließend auf “Fortfahren”.
Vergewissere dich, dass im Festplattendienstprogramm in der Seitenleiste der Name des Startvolumes angezeigt wird. Das Startvolume heißt “Macintosh HD”, sofern du es nicht umbenannt hast.
Suche nach einem “Data”-Volume mit demselben Namen, z. B. “Macintosh HD – Data”. Falls ein solches Volume vorhanden ist, wähle es aus. Wähle dann in der Menüleiste “Bearbeiten” > “APFS-Volume löschen” aus, oder klicke auf die Taste “Volume löschen” (–) in der Symbolleiste des Festplattendienstprogramms.
Wenn du aufgefordert wirst zu bestätigen, klicke auf die Taste “Löschen”. Klicke nicht auf “Volume-Gruppe löschen”. Führe diesen Schritt auch für andere Volumes aus, die sich unter Umständen auf deinem Startvolume befinden, außer für das Volume “Macintosh HD”.
Nachdem du alle Datenvolumes gelöscht hast, wähle in der Seitenleiste “Macintosh HD” aus.
Klicke auf die Taste bzw. den Tab “Löschen”, und fülle folgende Felder aus:
- Name: Gib den Namen ein, der das Volume bezeichnen soll, nachdem du es gelöscht hast, z. B. “Macintosh HD”.
- Format: Wähle entweder , damit die Formatierung als Mac-Volume durchgeführt wird. Das Festplattendienstprogramm zeigt standardmäßig das empfohlene Mac-Format an.
Klicke auf “Löschen”, um den Löschvorgang zu beginnen. Du wirst unter Umständen aufgefordert, deine Apple-ID einzugeben.
Schließe das Festplattendienstprogramm, wenn der Vorgang beendet ist, um zum Fenster “Dienstprogramme” zurückzukehren.
Wenn du möchtest, dass dein Mac wieder von diesem Volume starten kann, wähle macOS erneut installieren im Fenster “Dienstprogramme”, und folge dann den Anweisungen auf dem Bildschirm, um macOS auf dem Volume erneut zu installieren. Wenn du macOS nicht erneut installierst, wird beim Starten deines Mac möglicherweise ein blinkendes Fragezeichen (?) angezeigt.

Informationen zu APFS und Mac OS Extended

Das Festplattendienstprogramm in macOS High Sierra oder neuer kann die meisten Festplatten und Volumes für den Mac entweder mithilfe des neueren APFS-Formats (Apple File System) oder des älteren Mac OS Extended-Formats löschen. Dabei wird automatisch ein kompatibles Format für dich ausgewählt.

Das aktuelle Format bestimmen

Wenn du wissen möchten, welches Format derzeit verwendet wird, nutze dazu eine der folgenden Methoden:

Wähle das Volume in der Seitenleiste des Festplattendienstprogramms aus, und überprüfe die Informationen auf der rechten Seite. Wähle für weitere Details in der Menüleiste des Festplattendienstprogramms “Ablage” > “Informationen”.
Öffne Systeminformationen, und wähle in der Seitenleiste “Speicher”. Die Spalte “Dateisystem” auf der rechten Seite zeigt das Format jedes Volumes an.
Wähle das Volume im Finder und anschließend in der Menüleiste “Ablage” > “Informationen”. Das Fenster “Informationen” zeigt das Format des Volumes an.

Can’t Empty Trash on Mac

Check if the file is in use by any app

If you get an error about “File in Use”, then try closing the app that is using the file (in case you know the app). Alternatively, you can also close all the running apps to make sure that the file is no more being used by any of the apps. Now try to empty trash, if it still doesn’t clear the dump, keep reading.

Force Empty Trash in Mac OS X When File is Locked or in Use

In case you are getting a Locked file error, then press and hold the Option key, go to Finder → Empty Trash. This should have surely helped you in clearing Trash. The Option key signals macOS to bypass the locked files. Anyways, even if this didn’t work out for you, keep reading for more fixes.

Use third-party utilities

There are many third-party utility apps to forcibly empty the Trash folder. If you have them installed, give it a try. I would personally not recommend downloading and using them. That’s because they ultimately flash Terminal commands to delete Trash files, which we have given below, so have a look.

Empty Trash on Mac Using Terminal

This is the ultimate step you should take, only if all of the above have failed. As these commands will delete locked files without alerting you anything. Make sure you do exactly as it is written below.

Step #1. Open Terminal on your Mac.

Step #2. Now type, followed by space. Leaving a space is mandatory, so do not miss that step. And yes, DO NOT HIT RETURN AFTER YOU ENTER THE COMMAND.

Step #4. It’s now time to open the Trash folder from the Dock.

Step #5. Select all the files and folders from the Trash folder, drag and drop them into Terminal window. Doing this will add the path of each file and folder to the “Remove” command we entered at Step #3.

Step #6. Now you can hit Return and then enter your administrator password to continue the operation.

The deleting process will begin and might take a couple of minutes, depending on the size of files and folders you are deleting.

Try out this trick as well, if nothing seems to be working for you.

Step #1. First off, turn off your Mac. Then, you need to hold down command+R when starting your computer. Keep holding the keys until Apple logo appears on the screen.

Your Mac will enter into recovery mode.

Step #2. In the top menu bar, you have to click on utilities. In the drop down, you need to click on terminal. Next, it will open up a terminal in order to run a command.

Step #3. Next, you will have to type in the command cs0util disable and press return.

Then after, you have to click on the Apple on the top left and click restart.

Step #4. Next up, empty your trash as usual.

Wrap up

Assuming you have been able to empty the trash on your Mac. As these solutions have worked for many users, I’m expecting they have clicked for you as well. It would be really nice if you share your feedback and let us know whether you have found success using these fixes.

Forcing a Stuck Verifying .pkg Installer to Run in Mac OS X

Re-download the installer: Before anything else, you should consider that the downloaded .pkg installer, dmg, or updater may have been corrupted or perhaps is incomplete. The very first step should be to re-download the pkg or dmg in question, and always get it from a trusted source (for example, get the installer or update directly from the developer and never from a third party downloads site). If you know the installer package is legitimate, completely downloaded, and not corrupt through hash verification or otherwise, proceed as usual.

Assuming the .pkg, .dmg, or installer app is legitimate and still stuck on “verifying” then here is what you can do to force it to run:

From the Finder in Mac OS X, hit Command + Shift + G and enter the following path:

Locate the app named “Installer.app” from this directory and launch it directly

Navigate to the .pkg file that is stuck on verifying and select to open it

Success! Run through the package installer or update as usual

The package installer should now work just fine, whether it’s a software update for Mac OS, a third party app, or whatever else was stuck in the verifying stage. This seems to happen most often with installers that are run from a mounted disk image, but it can occur with downloaded .pkg updates as well.

Another possible option would be to disable Gatekeeper to prevent the verification process from unidentified and identified developers from running in the first place, but that is really not a good idea as it could open the Mac up to broader vulnerabilities or other issues.

For those who like to dig a little deeper to see what’s going on behind the scenes with the failed verifying attempts, you can open the Console app (/Applications/Utilities/) and you’ll typically find messages from launchservicesd and CoreServicesUIAgent with ‘Error -60006 creating authorization’.

I ran into this exact issue recently when using a Combo Update for Mac OS X on a particular machine getting it up to date with OS X 10.11.6. Strangely, the verifying process failed and multiplied itself nearly a dozen times, which unsurprisingly didn’t work at all. Nonetheless, running the .pkg file through the Installer app allowed the system update to install without a hitch. This is a fairly rare hiccup to occur with installations and updates, but I’ve seen it happen with Microsoft Office, VirtualBox, Mac OS X, and other downloaded updates as well.

Did this work for you? Do you know of another solution to this type of issue? Let us know in the comments.
