"To cast, give Chrome access in system settings." -- which system settings?

I was able to login with another account that was an admin account, launched Chrome and casting worked under that profile. Went back to user profile having issues and now it works, so that triggered something to start working. Had tried all the suggestions of removing chrome, turning Local Network and Screen Share off/on and none of that worked. So if you have another account, or if you don't just create one, log into that account and see if casting will work, and if it does that should fix the account/profile having issues.

This happens to me at least once a month and have no idea why. These are the 3 things that has helped in the past...Very annoying but try...

1. Type chrome://restart in the address bar and press Enter OR
2. Update Chrome OR
3. Toggle on and off permission settings in your system settings local network or screen recording permissions

Canary works for me, too. but Chrome Canary is newer than the stable version. And that is good news, and appears to be a problem with Chrome, not Apple. I am hoping that stable gets updated soon. Here is the difference between versions today:

Google Chrome stable

Updating Chrome

Version 129.0.6668.103 (Official Build) (arm64)

Canary

Chrome is up to date

Version 132.0.6790.0 (Official Build) canary (arm64)

Stupid question did you empty your trash. Also I used clean my Mac to uninstall Chrome. I think dragging it into the trash isn't sufficient.

I simulated this without using clean my Mac. I believe this is the missing link. Dragging Chrome to the trash isn't enough. This will absolutely get rid of all the copies of chrome in local access and it will ask the access questions again properly when you reinstall it.

Try this additional step:

You can also delete your profile information, such as bookmarks and history, by following these steps:

1. Click Go at the top of the screen
2. Select Folder
3. Enter ~/Library/Application Support/Google/Chrome
4. Click Go
5. Select all the folders, and drag them to the Trash 

I had a similar problem - Casting Tab would work but not the screen.

After suffering for a month found this setting from another forum:

Disable this in Chrome Settings: "Use graphics acceleration when available"

That worked !!

This problem just occurred to me. It was quite dumb and simple, but forgetting my network and reconnecting to it somehow worked. Maybe you can give it a try!

thankyou! had avoided this step as it wasn't in any other troubleshooting articles.

can confirm the reinstall method, with no other settings altered, has casting working perfectly ¯\_(ツ)_/¯

2023 MBP M2 / Sequoia / Chrome Version 130.0.6723.59

I have the same issue, my only solution has been to use my time machine to restore an older version of Chrome from the beginning of October 2024.

Not certain if this is a Mac or Google issue, but it is very annoying to keep being asked to authorize Chrome to cast and yet never being able to resolve the issue.

As an update to this: So after I wrote that, Sequoia 15.1 installed and the computer restarted and was back to being unable to cast. Repeating the 'dragging Chrome to bin then quitting and restarted' made no difference unlike last time. So I tried a safeboot start as suggested by online Apple Chat, my Macbook air had a hissy fit and after the first log in screen it went to the 2nd log in screen just flashed between that and a black screen, until I just shut the computer down. Restarted in normal mode and now I can cast again. Good I can cast again, but honestly don't know what's happening.

Try this.

1. Optional: Delete your profile information, like bookmarks and history:
   1. At the top of the screen, click Go  Go to Folder.
   2. Enter ~/Library/Application Support/Google/Chrome.
   3. Click Go.
   4. Select all the folders, and drag them to the Trash.

I signed out of my iMac, signed back in as my wife with administrator privileges. In her account, casting worked perfectly. I signed out, signed back in with my account, and it would not cast. I tried this several times, and it always worked for her account but not mine!

Hopefully this has permanently worked for some of you. It now doesn’t work for me again (even having originally fixed the problem and worked…)

I found a new thread where a user simply suggested to download Google chrome beta. I’m able to chromecast via that way!

It worked for me briefly, and then stopped working again. I found a permanent solution however!

Download Google chrome beta! Works perfect for me now. I did have to go back in the settings and toggle some things on etc like we originally tried. But it works for me now!

Update: So I updated Chrome today (01.19.25), and bam, I could not cast. No combination of the tricks mentioned in this thread would work, including the one that had worked before (enabling Screen & System Audio...). The best I could get was sound but no picture.

I bailed and d/l'ed a previous version of Chrome (Nov 24). Now it's fine again.

What gives? It's call "Chrome" cast, right? Not happy.

download Google Canary and use that. Casting works 👍
