Monterey upgrade VERY SLOW !!

Question

Monterey upgrade VERY SLOW !!

I have been trying for DAYS to install the OS Monterey on my relatively new iMac 27", 16GB DDR4, 1TB SSD (purchased in May-21) but it says it takes up to 3 days remaining ... and even if I let it run over night, it never completes the download, let alone the installation.

BTW, I have Fibre-Optics Internet access with 300 to 500 Mbps (see below), so it's not a slow connection.

Right now, it says 1 day remaining ... before it was 2 days and 3 days ... though I down-loaded already 6GB before, but today it started to download from scratch again ... see screenshot

I guess I have to skip this upgrade, unless you come up with a better upgrade package !!

On average it takes about 40 mins to download and install Monterey on my Macs. I would try upgrading while in Safe Mode.

Many of us have upgraded to Monterey (my connection is 33Mb/s) and it installed on my M1 iMac in a few hours (not excessive).

Before pressing the Upgrade button I checked my login items to see if there was anything unnecessary (there wasn’t). If you have apps in the dock set to open on start-up disable them temporarily
I don’t have virus checkers or cleanup apps but they should be uninstalled completely before the upgrade. (And not reinstalled)
I turned off my second monitor
I shut down any running apps especially Mail
I turned on my printer and let it go to sleep
I double checked that I had lots of space on the install drive
I left my USB connected Time Machine running but waited until it had finished its backup
I pressed the update button and it downloaded without issue and progressed to the full install
After the install I shut down and restarted, all was fine.

Thank you very much for your kind advise, I will try, if the new attempt today fails again ... currently it says, "About 10 hours remaining" (that's ridiculous)

Please advise how to start or apply 'Safe Mode' ?? ... never done or needed Safe Mode before

Thanks indeed :-) ... Werner

Thanks for your kind advise, most if not all applied to my situation and OS Monterey finally downloaded all 12.13GB, but the bar is still not full and is still says "Downloading ... " instead of Downloaded and restart to install (or something similar)

and just now, it confessed that the "Installation failed" ... :-( ... after approx. 8h of patiantly waiting to download :-(

Quite frustrating and annoying to be honest ... didn't expect these hiccups from Apple for supposedly top-of-the line iMac's

No matter where I click, AVIRA does not open or respond at all :-(

Antivirus’ load hidden helper apps which can prevent deletion of the application.

Ideally , before the initial uninstall (drag to the bin) you would go into the app settings and turn off loading on startup and after rebooting the Mac you can drag the app to the bin. However as you are past this stage try starting in safe mode (this doesn’t load the hidden helper) and then delete the app.

I checked the Avira web site and deleting is the correct uninstall and they don’t use an uninstall program.
