Message "Error while installing"

I’ve also been seeing this pop up error box on my MacBook Pro running the latest version of High Sierra version 10.13.6. I tried reinstalling the OS to correct it but it is still showing up. Choices on box are ‘cancel’ or ‘ok’. No clue what this is about

Just been in Apple support Chat

I ran Malware Bytes

https://www.malwarebytes.com/mac/

It detected one third part Malware file and some adware files

The Malware file path was Library/ApplicationSupport/.77B8A707-D8A5-4FBA-AAB9-7475351FDC70

Quarantined the Malware file (along with some adware files)

Error message on startup now stopped appearing.

I am having the same error pop up on my macbook pro. It started only a couple days ago. Why is this happening? Im also noticing that my screen display shuts off when I open my macbook all the way like normal. Please help!

I followed the directions to delete recent extensions on my Safari-preferences-extensions and the message stop popping up after startup.

SOLVED: For myself there may have been a couple sources of the problem. It has been a week now since I have had no error message displayed. One of the two possible causes was a file in "Library > LaunchAgents" called com.FHilEnLirpnWkxhyqvwjyFrmBeYMAgent.plist. I deleted this file and restarted the MacBook Pro. Unfortunately the error message still kept appearing. The next possible cause was in "Library > Preferences" called com.behenic.peglet.plist. I deleted this file and restarted my MacBook Pro again. It has been one week since then and I have not seen the error message display again.

Like others, this first started about a week ago (late Feb. 2021). I'm getting the same error pop-up after startup on an iMac desktop running El Capitan. I can get the error to not appear when starting in safe mode, or alternate OS installations, but it persists after disabling all login items, and is still there after re-installing a fresh version of the OS. Doesn't seem to affect anything, just **** annoying.

I’m having the same problem with my iMac. The same window. It just started a few days ago. Apple Support has no idea what it could be other than malware but it’s not the reason. Very frustrating and concerned there is something really wrong with my computer.

I have the issue on 2 separate iMacs. They are not connected in any way. I’m not a technical person and I contacted Apple Care but found no real assistance. Very disturbing and worrisome. Hope we can figure this out.

I just had a chat with Apple support

Their answer, which I'm not inclined to believe, is that because the error msg didn't resolve with a clean install it must be a hardware issue, and because it's on a 2015 MacBook Pro I'm 'on my own'.

I mentioned that other users have experienced the same issue starting at the same time (I (provided the link to this thread) and the answer was that "[these users] may be sharing the same issue with others with that same Mac model, which indicates hardware issues.

It's seems to strange to me that this issue, that appears to never been reportsd before (according to a Google search), suddenly manifests itself on several machines.

I get the exact same error and noticed this roughly 5ish days ago after updating High Sierra to version 10.13.6. I’ve cleaned all library and Internet caches deleted unnecessary files and while my machine is a bit speedier, after several attempts, I am still getting the error. I don’t believe it’s hardware related. It’s got to be something in the update. I am using an iMac 2011, 4gb 😔, i5

i don’t think it’s a hardware issue. So many people are having this issue on multiple computers with different models, all starting within the past week. Something strange is going on. I have a 2009 iMac running High Sierra. Yours is 2011, and I saw someone with a MacBook Pro. I wonder is we’ll ever get to the bottom of this.

If so many people here are experiencing this around the same date, it’s not coincidence. Nor do all of us have simultaneous hardware issues. I’m sure they’ve gotten calls about this.

I have been getting this same error message for the past week. I'm on a late 2009 macbook, running Sierra 10.12.06. I have not upgraded my OS in years and the last hardware upgrade was also years ago. This is not a hardware issue. It probably is malware, but I ran Bit Defender and it deleted the one suspicious file. I haven't restarted my macbook since then, maybe it needs a restart...

I have the exact same issue on the same spec machine. It ain’t no hardware issue.. I also recently moved to High Sierra, could be something to do with that install. The message is irritating but I’m not unduly worried about it..

Hi,

Same thing for me... this message appears since few days without any apparent reason. It seems that multiple Mac users are experiencing similar phenomene in the same days. I ran several anti-malware/virus tool but this message is still diplayed.

I ran Malware Bytes and it resolved the problem. I can see some of the users here also fixed it. Maybe you try to run it again or get rid of the malware file as mentioned by OceanDrifter. Good luck!
