safari – Audio/video drift out of sync (Catalina 10.15.4)

I’m running an imac 5k from late 2014. A few weeks ago, I was watching a movie on the apple TV app (not the device) on my imac. I started to notice that after about 2 min, the audio and video started to drift apart. Pausing the video briefly and then restarting fixed the issue for a couple of minutes and then the problem came back.

Today, the problem got really bad with Safari watching YouTube. After about 30 seconds the video becomes unwatchable. I checked Vimeo and the same thing happened. So it’s not just the AppleTV app or the website. Since this is also happening in AppleTV app, I’m wondering if it has something to do with some Apple software.

Now, when I watch YouTube with Chrome, there is absolutely no problems at all.

I’m stumped. Any ideas as to what could be going on?

Why is opening a link in a new tab on iPad Safari suddenly so finicky?

Out of nowhere – unless it was a recent small software update – I have noticed that whether or not Safari allows me to open a link in a new tab, by holding CMD while pressing it or holding the link and selecting the option
“Open in New Tab” – fluctuates a lot and seemingly randomly. Very often the feature is suddenly unavailable and then it comes back. Is this a new glitch or something?

Applescript – "Access not allowed (-1723)" is printed when trying to access Safari developer tools.

I am trying to create a script that lists all available open simulators to be checked in Safari developer tools. However, when I run the code, I get the following error. In the end, this script should open the inspector tool for a simulator device. I suspect this is generally not allowed, but I have granted accessibility rights to the terminal, so I have no idea.

Enter the image description here

listDevices.applescript:122:168: script error: „"Simulator" of menu "Entwickler" of menu bar 1“ kann nicht gelesen werden. Zugriff nicht erlaubt. (-1723)
tell application "System Events"
    tell process "Safari"
        name of every menu item of menu item where its name starts with "Simulator" of menu "Entwickler" of menu bar 1
    end tell
end tell

Why can't Safari 13.1 (Catalina) render certain Unicode characters?

After upgrading to macOS Catalina (10.15.4) it became clear to me that Safari (13.1) can no longer render my beautiful black truck. When I check this item in the developer console or copy the character to the URL bar, everything renders correctly, but only the white square appears in web view. The same problem exists on 2 other Catalina machines, but not on Safaris 10.14 and 10.13.

Any known bugs / problems regarding this phenomenon?

mac – Safely delete files downloaded from Safari

I'm sorry to ask such a basic question, but I'm helping my parents who have a Mac remotely, and I'm neither familiar with this system nor at home.

You received a fake order confirmation email and my father clicked the button to cancel the order. This opened another tab that claimed a security issue and downloaded several files. You couldn't close the tab.

First I told them to Shift-restart Safari so that the tabs would not be restored.

Second, they checked and deleted the download list (unfortunately before taking the photo I requested).

Now I'm not sure if the files are still on the computer. A number of sources, including, assume that deleting the download list will delete it, but I'm looking for a positive confirmation. Could someone familiar with OSX / Safari confirm this?

My mother told me that she couldn't find a folder called "Downloads" (or its localized version). Could it be that the folder is hidden when empty?

If there is such a folder: What is the safest way to empty the Downloads folder without risking opening one of the files? Remember I have to explain the procedure on the phone.

I don't think anything worse has happened. This looked like a scam that required them to call a phone number that would have asked them to pay for "technical support."

Thanks in advance.

Set two tabs to split the view in one action when using Safari MacOS Catalina

I'm using macOS Catalina 10.15.4 on a MacBook Pro 2018.

When using the Safari browser with two tabs Full screenSometimes I want to drag a tab and then display it side by side in split view.

The way I do it now, I drag a tab down from the tab bar, it opens in its own full screen view and then I drag it side by side as follows:

I wonder if there is a more efficient way to require fewer actions (hopefully a shortcut or even keyboard shortcut).

Context menu of the Safari extension, Get URL on which the context menu item is clicked

I created a Safari context menu button using the Safari Extension Builder. Now when I click a web page from any link on the context menu button (which I have created), the "URL" (which I have clicked) should appear as a warning message on my Safari browser.

I can't pass the URL from the website to the script so I can view it. Must display "URL" as a warning.

For this purpose I used a global HTML page with only one script tag.

Safari – MacOS UI freezes and hangs after security update 10.14.6 (18G4032)

I recently updated my MacBook Air 2017 256GB model, the latest security patch 10.14.6 (18G4032).

I started freezing randomly. Sometimes it will come back to normal after a few seconds. Sometimes the computer is completely stuck and I can only shut it down hard, sometimes I get graphic errors.

According to my observations, this is

  1. has happened since this security update

  2. After adding some extensions to Safari that I removed after the first freeze.

Any ideas what it could be and how I could solve it?

Safari on iOS does not load a page into my WordPress, but only a top level domain

I am trying to write a page to someone on my website. When I tested it, the URL in the text message changed from to, removing the end of the URL. When I manually type into iOS Safari, the same thing happens. This loads and removes the / test from the URL. My website is built in WordPress and the page loads easily in both Firefox and Chrome on my MacBook and Linux desktop. In Macbook Safari, I re-entered the URL after visiting the website and was able to load the page.

For some reason the permalink for a certain page is not called
