I have an iPhone 11 with the latest update and everything. But recently I noticed in my Files, there are several long screenshots from some sites I frequent, specifically comic websites and art websites. Sometimes I tend to press and hold the screen instead of scrolling and I suspect as a result, this has been happening. I don't know how to disable this feature. I tried looking the Accesibility settings but nothing seems to stand out. If I missed something, I'm not sure. Can someone please help me disable this function? I don't want to be accused of stealing people's work and getting banned.

Every month I have to file a report with a state agency through Safari. The website returns a confirmation with a long list that requires scrolling to view from top to bottom. While it is possible to scroll and snap screenshots: Is it possible to issue a single command to snap a screenshot of the entire list: essentially a **scrolling through** and **stitching screenshots together** to return a .jpeg **single screenshot** to ~/Screenshots? I think saw this functionality in a Windows screenshot tool: Hypersnap.

How to take a screenshot on Mac while keeping the aspect ratio of the capture area
I know I can open the Screenshot tool by pressing cmd + shift + 4 .

I know I can open the Screenshot tool by pressing cmd + shift + 4. I can drag the mouse around to specify the area I want to take a screenshot of, but I am wondering how I can keep the width and height ratio 1:1 when moving the mouse cursor. In image editing software, the combination is usually to hold shift while dragging. On mac using the screenshot tool, this means to lock one of the axis depending on where you start your drag motion. It locks the width if you start dragging up or down, and locks the height if you start dragging left or right. Pressing alt on the other hand makes the capture area grow in both direction. holding either cmd or ctrl seems to do nothing. I really hope there is a key combination to make the width and height scale the same, but I cannot figure out which key combination to use. **EDIT** My version of macOS is Mojave 10.14.5. And just to clarify, I want to keep the selection area to grow and remain at 1:1 ratio while actually moving the cursor around, similar to this: enter image description here Alternatively resizing the area in equal proportion to each other, meaning the width and the height changes so that the original aspect ratio is intact. The resulting image itself does not have to be 1:1 enter image description here

Change Date/Time format in the Screen Shot filename?
By default, screenshot files are saved with names like this: `Screen Shot 2016-07-12 at 1.07.34 PM.png` The date format is great, but the time format annoys me because it doesn't sort automatically. Is there any way to change the format to: `Screen Shot 2016-07-12 at 13.07.34.png`

How to record Mac screen above 60 fps? (120fps, 144fps, ProMotion)
Shift + Command + 5 generally works great for recording the screen, but it doesn't even seem to try keeping up with ProMotion or any above-60 FPS display.

Shift + Command + 5 generally works great for recording the screen, but it doesn't even seem to try keeping up with ProMotion or any above-60 FPS display. According to QuickTime Player, the directly saved .mov encoded FPS is 59.86. I'm trying to precisely scrub through a fast system animation, but I can't find any way to record the screen at that framerate - built-in or with an external app. Of course I could put a high-speed external camera to the screen and just try that, or find an high-tech HDMI capture card (as I use a Mac Mini), but those are kind of awkward solutions for what seems to just be a software lack.

Why does the "Show Floating Thumbnail" screenshot option uncheck itself several times per day in macOS 15.3.2?

Ever since updating to macOS 15.3.2, I have noticed that the floating thumbnail in the bottom right corner of the display was no longer appearing after taking a screenshot. Using Cmd-Shift-5 to access the options, I would notice that the corresponding option "Show Floating Thumbnail" would be unchecked. Initially thinking about an involuntary user error, I would check it. The feature would be back up and running for some time (maximum a couple of hours) and then it would uncheck itself again on its own. I tried to check it, then log out of macOS. Upon logging back in, the option would be unchecked again. What could be causing this? What could I do to solve it? I have already filed a report to Apple via the Feedback Assistant app.

Export MOV to MP4 with Quicktime on Yosemite
I have a screen capture of my computer screen using QuickTime's Screen Recording feature, but that saves it to an `MOV` format. I'd like to export it to `MP4.` Is that possible without installing anything else? I'm using Yosemite, and I'm pretty sure I could do that with Mavericks.

I have a working Python script that take screenshots of my single macOS display every minute using screencapture. The script essentially loops os.system(f'screencapture {output}.png'). Every once in a while, the screenshots suddenly start only showing my wallpaper. I know this isn't a screen recording permissions issue for Python, since the script works 99% of the time. Furthermore, once the buggy behavior starts, taking screenshots with screencapture myself on Terminal.app does the same thing. The bug never goes away by itself. The only fix I've found so far is to frustratingly restart my computer. Is there any documentation or fix for this behavior? Edit: To clarify, I am still able to take non-glitched screenshots with keyboard shortcuts like Shift + Command + 3.

I need a screenshot program that will freeze the current content (in my case, a streaming live lecture) and allow me to take a regional screenshot. In other words, once I hit the screencapture shortcut, the streaming content should freeze at the current frame, allowing me to drag and select a region, the screenshot is saved, and then I can repeat as needed. Without this feature, I may start a regional drag on a formula the speaker is showing, but in the meantime the speaker has moved on to another slide and I can't capture the info I need for my notes. The only Mac program I've found that does this freeze before capture is Snapz Pro X. The problem with this program is that the screen capture process is multiple steps and not built for rapid screen captures. The steps include typing the shortcut combo, mouse clicking from a number of available buttons to select the capture mode, moving or resizing the existing regional capture settings, and finally taking the screenshot by hitting return. Unfortunately, there isn't a way to set in the preferences or custom shortcut combo to automatically do a regional snapshot. Also, you also have to start from the last region you took -- so if you need to take a smaller region that is within the boundaries of the prior snap, you have to drag it out of the way first. Are there any programs besides Snapz Pro X that will allow a regional snap that freezes the current screen contents?
