Odd looking screen

[Herman G]

On Youtube I get more or less of a color screen


with the words 'sync' and 'wheel'. Apple doesn't know what to do.


On some other sites the whole screen is off-color


with those words all over it. It makes it difficult to read the screen at times.


Anybody have a clue? There will be a Safari upgrade when Big Sur comes.


But for now this happens. I am using Chrome more now.

Why did you make two posts?

Also I have absolutely no idea what you’re on about? Could you show a screenshot of this?

That right there is not normal, mate. - You have a malicious extension or something

i quit the extensions. nothing happened. apple didnt know what it was.

You might want to download, install and run MalwareBytes to see if there's any malware mucking up the works.

I just did that and several items were quarantined. No change.

In the past I've seen some bizarre looking tints and repeating/corrupted elements resulting from hardware GPU/VRAM issues.

But hard to get a sense of whether that's what's happening here (as opposed to malware) without seeing the entire screen in the flesh.

I can't do that. This is the best I can do, unless you have another suggestion. That's why I enrolled here, because i knew there would be 'nerds' and 'geeks'(slang for computer mavens!) here.
Malwarebytes quarantined what it found and said it wouldn't affect anything anymore. I could delete the 'deleted' items.
If I can get a whole screen I will post it in this thread.

Honestly I would just nuke macOS and reinstall the whole OS. There's a chance there's more happening than what MalwareBytes could catch anyway

 

[BrianBaughn]

I've had cases of malware that MWB wouldn't remove. At the time, I used Etrecheck to remove what MWB didn't. I don't know what to recommend at the current time.

Nuking would be the solution to give you the most peace of mind.

Here's a whole screen. What do you think? But when I put the cursor over it and tap a key, most of turns clear.

i saw that in relation to similar things. no help. maybe it's from old Mojave stuff on the Catalina disk?

Boot into "Safe Mode" (hold down shift key until Apple logo appears), if problem persists, then it is a hardware issue, if normal then Malware

Must be a hardware issue. i could make a backup tonight and run Etrecheck with full disk access after.

Entrecheck didn't find anything remarkably wrong. Could be some obscure files that Catalina doesn't like.
Just some websites in Safari. I got the Safari Webkit and ran it and nothing changed. Could be something with Safari
that Catalina doesn't like. Otherwise there were no serious issues, according to Etrecheck.

My recommendation remains the same. Wipe the drive, reinstall the OS.

Just wrote to Apple Suppport:

"Some sites give a strange display. An orangey color and the words 'sync' and 'wheel' all over some of them. Could it be some old obscure files from Mojave that Catalina doesn't like? Malwarebytes and Entrecheck show nothing remarkably wrong. Entrecheck shows a lot of old files that Catalina doesn't like. Could that be the problem? MacRumors suggests something like Internet recovery to reinstall everything. Does anyone think that will help? If those 'alien' files won't go away then what?"

Create a new Volume on your internal drive and clean install Catalina to the new Volume. Boot to the new Volume and setup as a new computer. Does the issue happen in the new Volume? This way you don’t disturb your current install.

a new partition or volume? and if i just get catalina and boot from the new catalina, wont there still be all those 32bit things catalina doesnt like on the original volume(or partition(the current install))? Maybe i should take away the 32bit things that mess up some safari pages? how do i know which ones, if thats the problem?


entrecheck shows no hardware issues. neither does apple hardware test.

 

[BrianBaughn]

Hardware issues don't cause "sync" and "wheel" to show up on a web browser!

Have you even tried creating a new user account just to test?

It really doesn't matter. For the purposes of this a partition and a volume will be the same, a volume will be easier but it doesn't matter. There's also nothing about "all those 32-bit things Catalina doesn't like on the original volume". Catalina won't run 32-bit binaries but that's it. It doesn't matter if you have 32-bit binaries or not, they just won't run. And the two system volumes are separate. That's the whole point. What's on one volume shouldn't matter to how the second volume behaves.

if the second volume is boot, it gets its data and programs from the first, right? if i make a a whole new volume and time machine to that it still will have those 'alien' 32bit binaries catalina doesnt like, i suppose.
maybe there are certain ones that mess up safari. there are the ones etrecheck says are there but are 32bit. that could be the problem.
isn't there a new safari coming with big sur?

If you create a new volume with a Catalina install all OS data and included apps will be from that install and completely separate from the other volume. You can access the data on the current volume but it will have its own copy of all the OS material.
You should not link it to the old time machine for the purposes of this.
32-bit binaries will not affect your Catalina install. It will not run. There’s nothing about “Catalina not liking them”. It just won’t run them. They do not create errors. - Regarding a new Safari - it’s new relative to what came bundled with Catalina when it was launched, but Safari 14 has also been released for Catalina though it is a slightly different variant

 

[HDFan]

Does this happen in all browsers - Chrome, Firefox, Safari?

so the second volume should be only for catalina?
