Sign In Required Loop

After spending two hours in a chat with Adobe tech support yesterday (and running many of the fixes suggested here) to no avail, today I ran all the maintenance tasks in the Onyx app on my iMac.

It worked. I no longer have the log-in loop when I open Photoshop CC 2019.

I have tried all the fixes on my iMac running 10.13.6. Nothing works. What a nightmare.

For when sign in loops keep happening when trying to use apps in Adobe Creative Cloud:

1. Quit Creative Cloud and close all Abobe processes, making sure Adobe IPC Broker is last to be closed.

2. go to %appdata%, go back one (from Roaming) to "Local" and then "Adobe" and delete "AAMUpdater" and "OOBE" Folders

3. go to %programdata% and then into "Adobe" folder,  rename "SLStore" folder to "SLStore_old"

4. go to "C:\Program Files (x86)\Common Files" and right click "Adobe" folder opening "properties"

5. Open the "Security" Tab under properties and assign all "allow" persmissions for the "Users" group. Click okay and ignore any warnings.

6. Close everything and open any adobe app (one that gave the problem) by right-clicking on it and choosing "Run as Administrator". Sign in and do the usual and it should open fine.

7. Close the adobe app and do the same with Adobe creative cloud, by right-clicking "run as administrator" and it should also work.

This worked for me first time but it has happened again and the fix did not solve it. At my wits end, waiting on adobe chat

Also worked for me (Muse 2018). BIG MASSIVE THANK YOU!!!

Great tip, finally something that works.

Nothing worked for me except when I did this solution:
(Make sure you have the right Library folder, that was the key)

"I FOUND SOMETHING THAT WORKED FOR MAC USERS!!! Windows fix is here: https://www.youtube.com/watch?v=SGYSZ...
( 1. Open Finder
2. Go to /Library/Application Support/Adobe (type that in the "Go to folder" search tab WITHOUT a ~ because ~/Library is the WRONG Library folder)
3. Delete the SLCache and SLStore folders (and delete SLStore_v1 if that's there too).
4. Right-click on the Adobe folder that you were just in, and click Get Info.
5. Click the lock and enter the admin name+password.
6. Add your active user account by clicking the + button and clicking Select.
7. Give Read & Write permissions to everyone listed at the bottom of the window.
8. IMPORTANT: Click the gear button at the bottom of the window and click Apply to Enclosed Items.
9. Click the lock to lock the folder once more. 10. Open any CC application; this should work now! (After maybe one "Sign-In Required," that is, but it shouldn't pop up more than once!)"

Tried all the manupulations with files deletion -  doesn't work for me.

Here is how it worked.

Signed in app, and closed after promt "Login successfull". Turned off internet. Opened app and choose trial for 7 days. Wait app to load. Turn on the internet.

I tried:

host file

server test

test message "pong"

reset host file

https://adobe.com  yes

GlobalSign RootCA Certificate      only the five checked boxes

Adobe help tech logged into my laptop and did the same stuff   no help

BUT

I deleted the

• C:\Program Files (x86)\Common Files\Adobe\OOBE\opm.db and finally SUCCESS!

TIP: Go to Task Manager (Shift+Ctrl+ESC) and "end task" everything Adobe before you try to delete the file
