MacOS Mojave install upgrade hung up

Hey all! I’ve got an iMac Retina 5K, 27-inch, Late 2015 with El Capitan (had needed it for older version of ProTools), and I’m stuck in the middle of a Mojave OS upgrade.

I started it approximately 60 hours ago, and it’s still stuck on the black screen with white Apple logo, and an “calculating estimated time” beneath it. The progress bar has been stuck at about 1/3 since I checked in on it 54 hours ago.

I’m only on here posting about it as I’ve seen a few relatable threads, but the solutions have been mixed: let it ride, and/or force a restart in recovery mode.

Any ideas on how much longer I should let it go before pulling the plug? I’ve got a time machine backup ready to go if need be.

Upgrade / reinstall takes usually few hours and not days as you mentioned (definetly not two days).

See if you can check the Installer log from the window menu or ⌘+L.

Make a quick note of the last line so that we know at which place it is stuck.

Then Go ahead with force restart and see if it resumes or continues and get's stuck at same line of the installer log.

If no progress or continuation, You may have to go into recovery and start the process again.

Hope it helps.
