A few weeks ago I had this problem occurring intermittently, maybe once or twice toward the end of a couple hour gaming session (retail WoW is the only game I regularly play on this computer).

This was the error message that I would get:

As a side note, early on I had initially planned to update my entire operating system, however I’m running a fairly old computer (not old enough that I should be having fully unplayable game issues, but it’s certainly not at the top of its class by any means). Anyway, it turns out that I cannot update the system beyond it’s current operating system at this time; not sure if Apple plans to make newer operating systems compatible with this model at a later time, but as for now I’m as current as I can be running Monterey 12.7.3 (basic specs below, followed by detailed system info):

Anyway, I believe it was about a week ago I had the problem resurface (apologies for not providing that error report, however it was identical in behavior and actions to reproduce). Didn’t have time to dig into it however seemed to go away on its own after returning from class ~6 hours later. That is until more recently I had it happen (one or two days ago, been really busy sorry). This is the relevant info I have for the problems that came up:
Was booted out of WoW and then from all processes shortly after:
sent back to black screen with apple logo and some writing over the top in white saying “your computer has restarted due to an error” or something, then it says to hit any key to proceed, and logs on like normal but a WoW error pops up as does a system error which I have provided both below:
WoW error:
The CAS system was unable to initialize: Tact instance creation failed. Error (7): not available

After some research I tried resetting the SMC by shutting down and then holding left shift, alt, control and power for 10 sec and then starting up. As expected, nothing changed.
I’m not computer illiterate but I have no background in tech so I did my best to read through and decipher what I could. It looked like a graphics issue and/or security issue, so first off I reduced my graphics settings substantially (I noticed as my computer would be nearing the point of terminating all processes and restarting as mentioned above, the fans would either be going full power; or it would be like they wouldnt engage at all. not sure if that’s relevent, but I noticed it was particularly bizarre to not have any middle speed, either all on or all off. Anyway…
I then followed a list of several blizzard fixes using both disk utility and terminal commands, and obviously the battle.net quick fixes as well as disabling/not loading/deleting addons and all that usual stuff. In order I did the following:
CAS System Unable to Initialize ClientHandler
Updated: 4 months ago Article ID: 13934
Product:
Common Problems
• Cannot start WoW. ClientHandler: initialization error: failed to create storage component.
• The CAS system was unable to initialize.
This error message usually signifies an issue with the Client Access Security (CAS) system responsible for authenticating and granting access to the game. Please try these steps to see if it helps you:
Windows
- Enable Secondary Logon
- Disable read-only settings for WoW folder
- Delete the “Indices” folder inside “World of Warcraft\data” folder
- Scan and Repair the game
- Create new administrator user account
Mac
-
Repair Shared Folder permissions
-
Repair Disk Permissions
-
Repair Application Support Folder permissions
-
Scan and Repair the game
-
Create new administrator user account
(I’m a mac user so obviously that’s what I did)
First:
Repairing Shared Folder Permissions (Mac)
Updated: 10 months ago Article ID: 24144
The Mac OS X® Shared folder holds information for Blizzard titles for all users. Sometimes it’s necessary to create the folder manually or repair folder permissions.
To find the Shared folder:
-
In Finder, select Go > Go to Folder or press Cmd+Shift+G.
-
Type /Users
-
Click Go.
Checked /Users to see if “shared” folder existed, which it did
Warning: The following processes modify permission settings using the Terminal application. If you are not familiar with Terminal and UNIX-like environments, proceed with caution. Incorrect commands may result in data loss or unusable system software. Improper alteration of permissions can result in reduced system security or exposure of private data. This method requires a non-blank admin password.
If the Shared folder exists:
-
Open Terminal (located in /Applications/Utilities)
-
Type the following: sudo chmod -R 1777 /Users/Shared
-
Press Return.
Note I had to enter my admin password and hit return before next step -
Quit Terminal.
Second:
Running Hard Drive Tests
Updated: 4 months ago Article ID: 25946
A corrupted or damaged hard drive can cause long loading screens, game lockups, crashes, and performance issues. Try the troubleshooting steps below to diagnose and repair hard drive issues.
If these steps do not resolve the issue, you may need to take the computer to a computer repair specialist to have the hardware issue resolved.
The Disk Utility can be used to diagnose and repair corrupted hard drive sectors.
Performed disk Utility First aid on Volume Contents, Volumes, Containers, and Disk. All were fine.
Third:
Repairing Application Support Permissions
Updated: 4 years ago Article ID: 82343
To repair Application Support file permissions:
-
Open Terminal, located in /Applications/Utilities.
-
Type or copy and paste the following command for the affected application: sudo chmod 0754 ~/Library/Application\ Support/Battle.net
-
Press Return.
If your system is not in English, you might need to translate Library/Application appropriately.
Note: You may be prompted for your administrator password when using the commands above. You may not see characters appear when typing, though it will accept your password.Did that.
Fourth:
Repairing Battle.net Games
*Updated: 2 years ago Article ID: 7655 *
Product:
Corrupted and damaged game files can cause a wide variety of problems and errors.
Updating the game can often resolve these issues, please check for game updates before using the repair tool.
-
Open the Battle.net desktop app.
-
Click the icon of the game you are trying to repair.
-
Click the cogwheel next to the Play button and select Check for Updates.
If your game is up-to-date and the problem persists, use the repair tool: -
Click the cogwheel next to the Play button and select Scan and Repair.
-
Click Begin Scan.
-
Wait for the repair to finish.

If you have tried these steps and still require assistance, visit our Technical Support Forums.Did that several times.
Fifth:
I created a new administrator profile called “Test” via the following directions:
Creating a New Administrator Account
Updated: 10 months ago Article ID: 34550
Sometimes it is necessary to create a new administrator account for troubleshooting purposes. Follow the steps for your operating system below:
Mac
Note: When you create a new administrator account, a separate Home folder is created so settings from another user account do not interfere with troubleshooting.
*
- Click on the Apple menu and select System Preferences.
- Click Users & Groups.
- Click Add (+) below the list of accounts.
- Choose Administrator from the New Account pop-up menu.
- Enter a full name for the account. Note: An account name is generated automatically. If you want to use a different account name, enter it now. After the account is created, you can’t change the account name.
- Enter the account password in the Password and Verify fields, and then enter a hint to help you remember the password.
- Click Create User.
- Log in to the new Administrator account and retest the application you were having problems with.
Tried everything here?
If you have tried these steps and still require assistance, visit our Technical Support Forums (World of Warcraft) (StarCraft II) (Diablo III) (Hearthstone) (Heroes of the Storm) (Overwatch) or contact us.
At this point I tried running the game as usual with no addons, and the system restarted erroneously just like it had before I tried any fixes. Instead of logging back into my main admin profile, for the first time I went thru the prompts and loaded up the new “Test” admin profile I had created earlier. I opened retail WoW launcher app and ran it without opening battle.net app or any addon loader app. Everything went perfectly fine, fans ran a little hard but no errors nor any shutdowns or issues.
So my first question is, of course:
Why did this fix it when nothing else did?
Next… I mean, it’s certainly nice having my really serious issues resolved, because now i can at least play the game, but it would be even better to have it playable on my initial user profile (rather than the “Test” profile) so that I can use the apps and things I like to use while playing the game (without reinstalling, or moving things and setting them up on the test profile, etc… you know what I mean). So my second question:
Is there a way to repair my normal admin profile so that things run smoothly, like they do on this test admin profile?
Lastly, I would hate to be setting up my apps and settings all over again, only to somehow taint this new user profile and have the same problem start all over again. That being said:
but that’s a rant for a different day…).
haha. Please <3
