Just installed Mojave on an older system that had been running El Capitan. So many problems now:

1) Every time I restart the computer it goes through the Mojave "Setting Up Your Mac" screens that normally only appear right after an install and therefore a lot of changes I've made get reset.

2) I can't sign into iCloud. I keep getting "errors" and "unknown problems"

3) The "MacOS needs to repair your library" loop is in full effect and I can't get it to stop.

4) Chrome pauses sync every time I restart it which it never used to do.

5) Lots of other things are acting weird but those are the main ones.

For this problem you can use in Terminal
Code:
sudo touch /private/var/db/.AppleSetupDone
and, if the problem persists, try
Code:
sudo touch /private/var/db/.AppleDiagnosticsSetupDone
For the rest... you should probably consider a clean install.

Sorry to hear about your problem with the Mojave install. It’s not advisable to install Mojave from El Capitan. As far as I know, it is required you need to have High Sierra installed first before installing Mojave. A friend of mine using an iMac, from El Capitan he upgraded to Mojave and also screwed up his Mac. All his programs were super slow and he encountered many freezes. It's also good practice to first clone your drive before installing any new OSX

Short & Sweet. CLEAN INSTALL. El Capitan is as close to the Kiss of Death you can get. Fusion Drive are another Apple disaster, just replaced mine with a SSD.

FYI: I “upgraded” from El Capitan directly to Mojave on my MBA. No problems whatsoever.

I migrated Mavericks apps and data to the High Sierra partition (High Sierra - Mavericks = 3 releases skipped, as opposed to Mojave - ElCapitan = 2 releases) without issues. You problems may be related to the fact that ElCap was HFS and Mojave - entirely APFS, whereas High Sierra allowed 2 way install - either as HSF or APFS. That explains why I didn't have any problems with HS.
