10 Screenshot Markup Tips and Tricks 

In preview/screenshot copy/paste a selection -> drag to reposition it (= level 2). Repeat with other selections (= level 3, 4, ...). Cut and paste it to the up most level part by part if needed to rearrange the stack. Choose "Color correction" > "sharpness" to blur all (level 1). Sorry for my quick-english, Servus.

Maybe you have the color set to white, or nothing? Try setting the line thickness to something thicker, and the color to black.

@@macmost Thanks for the reply! I have been checking line and color settings for months. I just found a support doc on the Apple site that suggested an NVRAM reset which I and it worked for a while. but as soon as I use a few apps and about 6gb of memory the markup circle on the right disappears. But if I open the screen grab file it's there. I thought it might be a low memory issue but I had the same issue on my MacPro running Monterey and 64gb of memory. I found a lot of other posts with the same issue and Apple's tech doc says that if you don't frequently restart your Mac things like that can happen, so I'll consider it a "Design Feature" (or flaw)

@@jackoneil3933 I've never seen things like you describe. I've never seen the markup button disappear like that. It shouldn't have anything to do with memory use or NVRAM, restarting your Mac or anything like that. Sorry, I'm not sure what is wrong, but it is not a design feature/flaw.

​@@macmost Thanks for the time Gary. It's a feature that would be handy in my work, and if I have to use it I can access it by opening the screen grab file, and then clicking the Markup Tool icon, and if that doesn't appear, I can reboot or do it on my PC as I usually am multi-tasking on both. I only have 8gb of memory on my Macbook and things can go wonky if I haven't rebooted for several hours and have an email client, a dozen browser tabs open and it hits the 8gb memory limit. I've experienced this on other Macs including my MacPro with 64GB and a redundant MacOS install on a separate boot partition.

Draw a rectangle around it. Make it the color you want with an opacity of 50% or whatever.

In Preview you can use Command+Shift+A. But in the floating thumbnail of the screenshot tool I don't know of any way. So set the "Save To" in the screenshot tool to Preview and it may get you the workflow you want.

@@macmost oh, thanks, that's a good one. Although from the design perspective they messed it. Two similar views (Preview vs clicking a thumbnail) and one has cmd shift A working, the other does not.

The most important thing is to store it in a cool, dry place where the temperature won't change much. Apple recommends getting the battery power near 50% and then shutting it down.

thank you sir@@macmost

No, you have to click to engage it.

@@macmost Thanks - too bad though

What question did you have about it? Do you mean the Markup tool that has a pencil with a line under it? That really doesn't do anything inside of screenshots as it is an image, not text, that you are marking up. That tool is more for when you are editing PDFs in other apps.

@@macmost I can´t figure out how to use it. In windows screenshot, i use the scale and highlight marker to highlight any part of the screenshot. Was hoping this would do something of the similar sort.

@@user-rj9xh6ss9u Try drawing a box instead. Make it solid, but set the Opacity of the color to 25% or something. Number 3 in this video.

It seems a little finicky, yes. I was able to get it to open, but only on the third try.

See ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kn_Tq8VTcJo.html

Screenshots are images. Highlighting is something you do with text documents.

It is pretty much the same. Look in Music, Settings and turn off Apple Music.

It is built in. You can add it to Control Center or the Accessibility shortcut.

@@macmost I was referring to the magnifier in the photos section it used to be under Markup

@@parkwaypony1914 I don't think the magnification "loupe" tool was ever in the iOS version of the markup tools, though I could be remembering wrong.

@@macmost it was in there prior to iOS 7 - if I had something a photo and want to magnify a particular section of to pic I could use that and then save the photo with that section magnified

@@parkwaypony1914 Ah, so back in 2013? No wonder I don't remember it. Well, I suppose you could still do it, it will just take a third-party app.
