“Error while installing” is a browser hijacker app that is known for targeting Mac browsers and causing uncontrolled ad-generation and page redirects in them. “Error while installing” can be unknowingly downloaded through file bundles or after opening spam email attachments and clickbait adverts on the Internet.

This unpleasant application is only one of the many representatives of the browser hijacker category. These apps are very common and many users have them on their computers (Apple or Windows) without even paying much attention to their presence. For the most part, a hijacker won’t cause any direct harm or damage to a computer it is installed on, which is why you could have such an app attached to your browser for months or even years without anything bad happening. However, if “Error while installing” has latched on to your Safari, Firefox, or Chrome and has made changes in their homepages and search engines, it is still advisable that you quickly uninstall this invasive app because, even if it won’t directly damage your computer, there are certainly a number of issues it may indirectly contribute to.

Error while installing for Mac

“Error while installing” for Mac is a PUA (potentially unwanted app) that hijacks the main browser and makes unauthorized changes in it. “Error while installing” for Mac is primarily aimed at providing certain sites with more traffic, which is why it tends to cause sudden page redirects in the browser.

This site-promoting activity irritates most users and makes them seek ways to eliminate the unpleasant app. However, even if you are among the few who don’t mind the obstructive redirects or who simply don’t use their browser as often, it is still of great importance that you dispose of this browser hijacker as soon as possible. As we mentioned, though, it doesn’t harm your machine directly, it could still lead to certain problems in an indirect way. The biggest one of these problems is the possible infection of your computer with viruses such as Trojans and Ransomware coming from unsafe sites that the hijacker may potentially redirect you to.

What is Error while installing?

“Error while installing” is an add-on for a number of Mac browsers known for its tendency to modify the affected browsers without the user’s approval. “Error while installing” does this in order to turn the browser’s tabs into advertising space where different sites can be promoted.

As we said, this could potentially jeopardize the safety of your Mac as some of these sites may not be safe to interact with. Unfortunately, the hijacker doesn’t really leave you with any choice with regard to what sites to get redirected to. Therefore, removing the unpleasant app, along with its annoying popups and banners, is the only viable option in this case.

The Error while installing app

The “Error while installing” app is an aggressive advertising browser attachment that is typically distributed as an optional install included in installation packages. The “Error while installing” app is known for forcing sudden page redirects in the affected browser, which may potentially lead to the compromising of the system’s security.

If you don’t want to risk getting suddenly redirected to a site that may be used as a malware distribution center and if you want to decrease the chances of encountering Trojans, Spyware, Ransomware, and other malicious threats, our advice for you is to immediately check out the removal guide we’ve prepared for our readers and, with the help of its instructions, uninstall the invasive browser hijacker.

Remove “Error while installing expecting value” from Mac

Remove “Error while installing” from Safari

To remove “Error while installing” from Safari, you should see if the hijacker has added any unwanted components in the browser without asking for approval and delete them.

  1. Start by opening Safari and selecting its menu from the top.
  2. Then click on Preferences from the browser menu and go to Extensions.
  3. If there are any extensions installed in the browser that you don’t recognize or trust, uninstall them to remove “Error while installing” from Safari.
  4. Once this is done, restart the system, go to the browser again, and test it for a while to see if there are any hijacker symptoms.

Step 1: Quit the “Error while installing” process

If “Error while installing” is still not gone from your Mac, the first thing you ought to do is find the hijacker process and stop it. You can do that from the Activity Monitor of your Mac. To get there, open Finder, click on Applications from the sidebar to the left, and then go to the Utilities folder. In there, you will see the Activity Monitor so go ahead and open it.

Inside the Activity Monitor, you will see the processes that are running in the system and among them should also be the one that “Error while installing” has launched. If you see a process named “Error while installing”, click on it and then click on the button in the top-left corner and then select Quit.

Mac Activity Monitor Quit Process

It is highly possible that there won’t be a process with the “Error while installing” name in there, in which case you should look for other suspicious entries that you think may be related to “Error while installing”. Potential red flags that you must look out for are high CPU and RAM usage as well as process names that don’t seem familiar and/or related to any of the programs that you have on your computer.

To learn more about a given process that looks questionable, it’s best to look up its name on the Internet. If your online research confirms that the process you suspect is probably from “Error while installing”, go ahead and quit that process.

Another way you could potentially tell if the process must be stopped is to select it in the Activity Monitor and to click on Information (the “i” icon in the top-left).


Once you do this, select Sample, then Save, and save the Sample on your Desktop.


Next, go to the sample file and drag-and-drop it to the free malware scanner that you can find below:

    If our scanner detects that there may be malware code in the scanned file, this should tell you that the process you sampled is probably not supposed to be running in your system, in which case you should quit it like we showed you above. Note that even if the scanner detects no threatening code, if looking up the process name revealed that the process is probably rogue, you should still quit it.

    Step 2: Remove the Hijacker app


    Mac users usually get malware on their computers after they install questionable free software from third-party download sources. In most cases, the malware is hidden in those third-party apps, and it gets installed on the machine alongside the app that carries it without the user realizing anything. If you think you may have any such applications on your Mac, it is crucial that you single them out and delete them.

    To delete suspicious apps from your Mac, go to Finder > Applications and look at the most recent entries. If any of them look questionable or are unfamiliar to you, delete them by dragging them to the Trash icon on your Desktop. Of course, if there is an older app that also looks like it shouldn’t be in the system and/or could potentially be related to “Error while installing”, you should delete that one too. Also, though apps downloaded from the official Apple App Store are highly unlikely to contain any sort of malware or unwanted software components, this is still not beyond the realm of possibility and so, if you think an app downloaded from the Apple App Store might be responsible for the presence of “Error while installing” in your system, delete that one as well.

    Lastly, do not forget that you should also empty the Trash to finalize the uninstallation/deletion of the undesirable apps.

    Step 3: Safe Launch the browser

    The next thing that must be done is to clean the browser from any remnants of the hijacker, but before you do this, you must start Safari without allowing any sites linked to “Error while installing” to automatically load in it. You can do this by closing the browser, pressing and holding the Shift button, and opening Safari again. Normally, no sites should load in Safari once you do this but if anything loads, then close the browser once more, disconnect from the Internet, and perform the shift-launch again.

    The easiest way to disconnect from the Internet if you are using wireless connection is to click on Wi-Fi from the menu bar at the top and then on the Turn Wi-Fi Off button (you can re-establish your Internet connection from that same menu after you are done with the guide). On the other hand, if you are using cable Internet, it is enough to remove the cable from the Mac to stop your connection and plug it back in once the guide is completed.

    Step 4: Delete hijacker and settings from Safari

    Now that Safari has started anew and no hijacker-related sites have loaded, go check the Extensions of the browser again in case you missed anything earlier and/or in case any of the extensions you deleted have been reinstalled without your permission.

    After you check the Extensions of Safari, go to the Privacy tab (Safari Menu > Preferences > Privacy), click on Remove All Website Data, and then click on Remove Now. This command deletes temporary site and browser data which may contain information about “Error while installing” and that is why it must be deleted. If you haven’t done this in a while (or ever), you will likely have to wait for several minutes before the deletion completes – be patient and don’t turn off the browser until the process finishes.

    Remove Website Data Mac Safari

    After Privacy, go to General and there check the address of the browser’s starting page. If that address is for an unknown and/or questionable site that “Error while installing” has enforced as your homepage, change it to a reliable and well-known site – one that you want to be the new Safari starting page.

    Default Home Page

    Lastly, open the History menu of Safari, click on Clear History and choose an appropriate deletion setting. We suggest you set it to All History to make sure everything is deleted and then click on the Clear History button to execute the command.

    Step 5: Check your other browsers

    All other browsers that you may have on the computer should also be checked for settings and unwanted extensions imposed by the hijacker. Even if you only use Safari on a regular basis and don’t normally open the other browsers, you should still make sure that they have nothing related to the hijacker in them.

    firefox-512 Removing ads from Firefox for Mac:

    To clean Firefox, start by opening the browser, selecting the browser menu in the top-right (three parallel lines), and clicking on Add-ons. There you will find the different add-ons that are presently installed in Firefox and will have the opportunity to delete the ones that are not supposed to be there and/or those that may have been installed by the hijacker. Delete everything that you deem potentially unwanted as well as all extensions that you don’t remember installing.

    The next thing you must do to clean the Firefox browser is go to this page and complete the steps included in there – they will show you how to refresh the settings of Firefox so that there won’t be anything left from “Error while installing” inside the browser.

    chrome-logo-transparent-backgroundRemoving ads from Chrome for Mac:

    Go to your Chrome browser, select the three-dots in the top-right, hover the mouse over the More Tools option, and choose Extensions from the submenu that shows up. In the Extensions page, do the same like with the previous two browsers, deleting all extensions that might potentially come from the browser hijacker. If you don’t normally use the Chrome browser, you could also delete all of its extensions just to be sure that there’s nothing in there that could be related to “Error while installing”.

    In case a given extension doesn’t go away once you select its Remove button, try disabling the extension first and then quickly select the Remove button again (it is common for rogue extensions to not get uninstalled once you select the Remove button unless they have been disabled first).

    After dealing with the undesirable Chrome extensions, go to the browser menu again, select Settings, and click on the Search Engine from the left panel. Then go to the Manage Search Engine options and look through the listed search engines. If any of them are unfamiliar and/or suspicious, click on their respective thee-dot icons and select the Block option to prohibit this search engine from being used by Chrome. The only search engines that the browser should be allowed to use are ones that you are sure can be trusted – ones like Google, Bing,  Yahoo, etc.

    Finally, to revoke any other settings changes the hijacker may have made in the Chrome browser, go to this page and complete the steps available there.
