They may or may not be granted to your app during Apple’s review process. So I’m all set, right? Well… Temporary Exception EntitlementsĪpple offers a couple of temporary exception entitlements. On a hunch, I tried using … mach-register.global-name instead of …mach-lookup.global-name and – tada – it worked! I tried adding it to ScreenFloat’s entitlements file, with as its value (this temporary entitlement expects an array of string values), but that didn’t help – the same denial and console output occurred. In the back of my mind, I remembered a temporary exception entitlement, but it wasn’t quite the same – -name. So registering a global Mach service is denied on macOS Sierra. The output in Console.app when trying to launch an interactive screencapture with NSTask. Since I was absolutely sure I’m not launching screencapture via NSTasktwice, I took to Console.app to see if anything unusual was reported there. Screencapture: cannot run two interactive screen captures at a time Now, on macOS Sierra, I’ve been getting reports that screenshot creation didn’t work anymore, so I investigated.Īt first I thought it might be the keyboard shortcut API that has undergone some changes, but that doesn’t seem to be the case, as I saw something actually occurred when I pressed the keyboard shortcut – Xcode’s console printed: On OS X El Capitan and earlier versions of Apple’s operating system, this worked perfectly fine. Despite a few limitations, it’s a solid screenshot tool.In my app ScreenFloat, I use the command line tool screencapture via NSTask to create screenshots. I didn’t appreciate just how useful ScreenFloat’s ability to create floating screenshot windows would be until I started using it. (I currently use ScreenFloat side-by-side with Jing just to get that functionality.)īut even without the capability to annotate or share screenshots, ScreenFloat earns a place on my Mac-though not in my Dock, since the app wisely offers a preference to live exclusively in your menu bar. Skitch (which I merely like), ScreenFloat doesn’t let you edit or annotate your screenshots or easily share them with others-I long for a button that automatically uploads the current screenshot somewhere and saves, to the Clipboard, the URL for the uploaded image. I wish that I could rely on ScreenFloat as my sole screenshot-taking utility, but I can’t yet. You can optionally rename and tag your saved screenshots. I do wish ScreenFloat would let me control which programs appear in the Send To list, however I never want to send my screenshots to, say, ColorSync Utility.Īnother useful feature is that ScreenFloat keeps a history of all your screenshots in its library, making it easy to reuse an old image should the need arise. When I need to prep screenshots for Macworld, I take them with ScreenFloat and then send them to Acorn for further editing. Click the screenshot window’s settings (gear) icon (or control- or right-click anywhere on the image) and the resulting menu lets you choose the image’s window level (either a normal window or an always-floating one), copy the screenshot to the Clipboard, delete the screenshot, or-most awesomely-send the screenshot directly to another app. But the app packs plenty of other functionality, too. That’s the crux of what ScreenFloat does-it makes it easy to take screenshots that float on your screen until you’re finished with them. That means I often end up rearranging my windows so that I can see the necessary information in the Mac App Store window while typing in my text editor. The Mac App Store provides all this information, but doesn’t let me select it-so I can’t just copy and paste it. When I’m writing a software review here at Macworld, I need to note some key details about the program in question: the precise name and version number, the developer, the minimum system requirements, and that sort of thing. To help explain ScreenFloat’s basic functionality, let me use the example of our review-writing process, as when I sat down to write this review, I immediately realized that I could use ScreenFloat to simplify the process. The program offers a variety of clever-and cleverly implemented-features, lacking just a couple extras that could send it into the 5-mouse stratosphere. But even if you never need images of your Mac’s screen, ScreenFloat can make some of your daily computing tasks more convenient. Mac App Store link) can make the process easier. If you need to occasionally take screenshots,
