Message "Error while installing"

After reading 60 posts about 'Error while installing', I recognize we may use Security Software to isolate or remove this nuisance message at startup. I choose to wait, primarily, because I now can CANCEL the 'Error while installing' message and it does not return during the current login session. I also tried a Guest Login which did not produce the 'Error while installing' message.

I've not used any Security Software product during my use of my MacBook Pro nor my iMac; but I do check for updates just before Shutdown for each Login Session.

Hi. I used CleanMyMacX software. Its free. The only thing with it is that it will detect the malware but you have to purchase it to auto remove. That said it lists the malware and allows you to click and remove malware manually. I had over 19 on my list and removed them one by one. Small hassle but it worked and the message does not pop up anymore. Hope this helps. Cheers!

So, now it seems fairly certain it's a malware issue for everyone, I'm curious how I got it. In 35 years of mac I've not had a virus or malware and my other machines are all clean.

The only new app installation I made prior to the issue developing on the machine was Zoom(US)

Anyone install Zoom(US) just prior to the error appearing ?

My iMac, when I looked today, does not display the 'Error while installing' notice.

As for my MacBook Pro, I just cancel the notice and it does not interrupt my Login Session.

I admit, I've been spoiled by Apple since leaving Windows OS in 2009; I hope I may continue to be spoiled by all the Apple

products I use.

There has to be something to connect widespread users whom, seemingly from this thread, are running older OS and machines.

The error msg appeared for me upon restart after installing Zoom(US) on Thursday 25th February.

n=1 and correlation is not causation, however.....

I have the same problem with my applemac pro. The error and then Expecting value: line1 column1(char0). It began appearing on my screen a few days ago. I've no idea what its referring to. If we are all having the same problem, is this Apple's way of saying we now have to buy another of their laptops?--something I thought I had to do until I se so many have the same issue and all at the same time.

Whats this about.

I gave the filename of the malware file I deleted (it is up thread somehwere), you could try that.

The file name is preceded by a . [dot] so it's hidden

Cmd + Shift + . [dot] will reveal hidden files

You can then delete it and see if that resolves your problem

OK I ran CleanMy MacX and it detected several Malware, I purchased it and deleted the Malware

and so far seems to have stopped the error message popping up randomly every few hrs.

Just a mystery where it came from as I am very careful about what I download and as far as I

know nothing updated or was downloaded in the last 2 weeks.

Take a look at the replies in the thread

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

it is a hidden file - filname starts with a . [dot]

Delete the file (or move to another folder if you feel unhappy deleting)

restart

I didn't see this file in this location.

Odd thing, I turned on my Kindle and it was trying to install ZOOM. I really don't want it on my Kindle, so deleted it. I realize that that is android, but I wonder if there could be any kind of connection...at...all.

Anyway, now I'm on the watch to see if the message pops up again.

Thanx for the help!

My system is also too old to install Malware Bytes. I don't have an 'Application Support' where I can look up '. [dot]' - that youtube video didn't help.... this box keeps coming up. I got an email recently that my passwords were involved in a data leak. Would this be related? Should I be concerned? Gonna try to reboot and wipe my computer and change pwords but not sure it will get rid of that box...

I'm getting this on my 2018 MacBook Pro. Just started maybe 2-3 days ago. Luckily mine was already about to get sent in to apple to have a key repaired.. so hopefully they can use it to take a closer look :/

I had the same dialogue box beginning late February 2021. Today, installed Malware Bytes, which found 20 items for quarantine. One of those was the recently identified Silver Sparrow malware. Malware Bytes quarantined the items, then restarted my MBP (OS 10.12.6), reran Malware Bytes, which found no items in need of quarantine. The dialogue box we've all been experiencing has not reappeared.

Thanks, Oceandrifter for the research and reference to Malware Bytes.

The problem I have is that I have a Macbook Pro OSX 10.9.5 which is too old a computer to install this Malware Bytes. What else can I do to resolve this problem. I'm dependent on work using Zoom and so cannot uninstall.

I have this exact same message for a few weeks. Seems to have started around the same time as everyone else.

I have an older iMac (Intel - Late 2008). So this appears to span across a whole host of different Macs.

And just like other users, whether i select Cancel or OK. It still comes back.

Any advice would be fantastic, thanks.
