From this thread?

Open Terminal and arrow up until you see the command, you entered, copy it and paste it in a reply here. It cannot be undone, but it might be able to be reversed.

Or, copy it from where you got it originally and paste it in here so we can see it or linked to the page you used.

There's no such thing as undo in Terminal. The presumption is you know what you're doing when you enter any commands.

Restart in Recovery Mode and reinstall the OS.

The commands are purportedly:

defaults write -g com.apple.SwiftUI.DisableSolarium -bool YES

and:

defaults write -g com.apple.SwiftUI.DisableSolarium -bool NO

and in either case, restart Finder.

If you entered something else, who knows what might happen?

And who knows what happens with these commands.

When experimenting in Terminal, always have backups, and preferably only experiment on a spare or testing-focused Mac. There are commands that cannot be undone.

I did that yesterday when I spoke to apple on the phone. Didnt change anything. :(

If you also restored from a backup, then you likely brought the problem right back. You need to restore from a backup made before you experienced any problems.

Create a new user account and test to see how that one behaves. It should behave normally, which means you screwed something up in your main account.

This test is just to confirm the OS is working as it should when not logged into your main account. You can delete the test account afterwards after confirming one way or the other.

There is some what:

Take this

defaults write com.apple.Music com.apple.SwiftUI.DisableSolarium -bool YES

to undo it you would enter

defaults write com.apple.Music com.apple.SwiftUI.DisableSolarium -bool NO

Do you have any possibly idea please?

If I knew what was wrong I would have suggested something.

You can try adjusting the Appearance settings toggling between them to get it to redraw the ui elements.

defaults delete com.apple.dock && killall Dock. i got this from you tube

Neither of those would cause the problems you describe. It just resets the Dock settings to default.

There is something else wrong.

Please help me someone, I'm at my wits end with this. I update to Tahoe the other day, wasn't keen on the layout cos of the new 'liquid glass' thing, so read that you can turn it off. I went into terminal and copied & pasted something and now it's changed my dock bar. It's lost it's frame. Not only that, my pop up boxes have gone funny and you can't read them (e.g when it says to shut down). I will try and enclose some screenshots, not sure if I can as I've never been on here before.

Real lack of any specific details here...

Sure can post screen shots... either drag and drop or use the editing tools.

Whether it works or not, and whether it breaks things elsewhere, no sé.

I'm a bit surprised anyone would enter that command, when at the very top of the link, the poster clearly states:

There's some visual issues, but it's mostly usable.

Mostly? What else does it break?

You're surprised? People have microwaved their phones to "charge" them based on social media. There was also that one that involved changing the system date on the phone to get a "retro interface" which bricked the phone. Apple had to release an update to prevent people from doing that.

I am no longer surprised.

You're surprised?

Only a bit, and only because the person said, right there in the post, There's some visual issues, but it's mostly usable.

And yet, people enter the command anyway.

But otherwise, yes, the amount of stupidity (more like a severe lack of common sense) among humans can be both astounding and disheartening.

There have been any number of "Deaths by Selfie", where people intentionally went to dangerous places (such as "on the railroad tracks", "standing on the edge of the Grand Canyon with your back towards it", etc.). There was a guy who took a "rattlesnake selfie." The rattlesnake objected and injected him with its venom. Doctors had to use up the anti-venom supplies of two hospitals to save his life (and arm?), and his share of the medical bill came to $153,000.

CBS News – "Rattlesnake selfie" results in a $153K medical bill

Since the rattlesnake selfie guy lived, and was not rendered "unable to reproduce", he was ineligible for a Darwin Award. But others did win it, like the guy who wanted to test if his new jacket was 'stab-proof', and tested this by stabbing it repeatedly with a knife WHILE HE WAS WEARING IT .
