Performance

• Finishing a screen recording no longer bogs down an Intel Mac. Sealshot reads the text out of a handful of frames to describe the recording, and that read was running at the same effort it uses when you’re sitting there waiting for it — on up to 24 frames, for a recording you’d already walked away from. It now uses the lighter setting reserved for background work, and yields to anything you’re actually doing, so capturing or editing stays responsive while it finishes.

• Tagging a new capture is quicker. The checks for faces, documents and barcodes each re-prepared the image separately; they now share one pass. Most noticeable on Intel Macs, where that work has no dedicated hardware.

• Captures are ready much faster on Intel Macs. Reading the text out of a screenshot could take anywhere from 15 to 37 seconds on those machines, which held up the searchable text, keywords and title for every capture. Two things were behind it: the same screenshot could be read twice at once, and the pass that double-checks hard-to-read lines was doing far more work than it was worth. Text-heavy and blurry captures now finish two to three times quicker, and every line of text is still found — only the extra double-check of a few blurry lines is skipped.

• Switching to the text tool is far quicker on Intel Macs. Before showing selectable text, Sealshot checks whether the picture contains any text at all — and that check was doing a full, careful read of the whole image just to answer yes or no, which could take half a minute on its own. It now takes a fraction of a second.

• On Intel Macs, Sealshot no longer sharpens the image before reading text for selection. The sharpening quadrupled how much there was to read and cost far more time than the slightly clearer text was worth on those machines. Apple Silicon Macs still sharpen as before.

• Background text reading now gives way to whatever you’re doing, instead of competing with it, so the text tool responds sooner after a capture.

• A new capture is no longer read twice over. Sealshot reads a screenshot once for search and keywords and again when you select text — the same picture, the same words, twice. The heavy part of that work is now done once and shared, so whichever comes second finishes much sooner. Selecting text still gets the most careful read; only the duplicated effort is gone.

• Selecting text, Find in Image, and Smart Redaction are unchanged: when you ask Sealshot for text yourself, it still does the most thorough read it can. Apple Silicon Macs see a smaller share of the same speed-up.

• The capture overlay opens more smoothly. The frozen picture of your screen behind the crosshair used to be prepared on the very first frame you saw, which made the overlay feel like it caught as it appeared.

• The capture crosshair and magnifier now follow your pointer directly. They were only being redrawn when the highlighted window changed, so on slower Macs they trailed slightly behind the cursor.

• Selecting text on a capture you have already opened is now instant. Sealshot remembers the text it found while the app is running, so switching between captures and coming back no longer re-reads the picture from scratch.

• Switching to a capture with Enhance Clarity applied no longer freezes the editor. A large enhanced image used to be prepared for display all at once before anything appeared — over a second on a big capture. The picture now shows immediately and sharpens a moment later, and flicking through captures no longer leaves discarded work running in the background.

• Scrolling a tall capture in the editor is much smoother. The light and dark chequerboard behind the picture was being redrawn across the whole canvas on every scroll, however little of it had actually moved — on a long screenshot that was most of a frame’s worth of work each time. It now repaints only the strip that changed.

• Flicking through captures no longer makes the strip stutter. Opening a capture had to unpack its full-size picture before anything could be drawn, and that unpacking happened on the same thread the strip scrolls on — so each capture you passed through cost a visible pause. Sealshot now shows the capture’s existing thumbnail for a moment and unpacks the full picture in the background. The longest pause when switching dropped from about 75 thousandths of a second to under 19.

Fixes

• Captures look sharp at every zoom level, not just 100%. The canvas was always drawing at your screen’s own resolution and then letting the graphics card stretch or shrink that picture to whatever zoom you’d chosen — so at 94% or 125% every pixel you saw came from a compromise. It now draws at the size you’re actually viewing, which is why 100% always looked right and nothing else quite did. Most noticeable on non-Retina displays, where there was no spare resolution to hide it.
• Text looks much better when a capture is zoomed to anything other than a whole number. Sealshot deliberately keeps zoomed screenshots pixel-sharp rather than blurry, but it was doing that at every zoom level — and at in-between zooms like 125% or 156% that meant some pixels were doubled and others weren’t, which chewed up letter shapes. Whole-number zooms (100%, 200%, 300%) stay pixel-sharp; everything in between now scales smoothly. Most noticeable on non-Retina displays.
• Fixed: zooming up to 100% left the picture slightly soft, while zooming down to 100% — or getting there with ⌘-scroll — looked right. Sealshot animates the zoom, and the animation could stop a whisker short of where it was headed, so a capture the editor reported as 100% was really being shown at 99% and resampled. Every zoom now lands exactly on the number shown, so 100% is once again a pixel-for-pixel view of your capture. Most noticeable on non-Retina displays.
• The tools are now greyed out while Sealshot is busy reading text, redacting or enhancing a capture — matching what extracting data already did. Before, the tools stayed clickable underneath the progress card for some of them.
• Fixed: cancelling text selection and then starting a redaction scan showed no progress at all. The cancelled read reported itself finished a moment later and dismissed the scan’s progress card along with it.
• Fixed: the spinner next to a new capture’s name could sit there for a long time on Intel Macs, waiting for something that was never going to happen. That spinner means “this name isn’t final yet” — but on those Macs the name is already final the moment the capture is saved, and the spinner was really tracking the text-reading that happens in the background. It no longer appears when the name won’t change, and everywhere else it now gives up after 8 seconds rather than spinning indefinitely.
• Selecting text in an image can now be cancelled. Reading the text out of a capture shows the same progress card as redacting and extracting data — with a Cancel button, and Esc works too — instead of a small badge you had to wait out. Cancelling puts you back on the pointer and restores the picture you were looking at.
• Switching to another capture now stops whatever Sealshot was working on for the old one. Enhancing clarity, redacting and extracting data used to keep running after you moved on, throwing the result away when they finished — and worse, the button stayed dead on the new capture until the abandoned work ended. Taking a brand-new screenshot mid-scan had the same problem.
• Fixed: the capture strip along the bottom of the editor could show only the capture you had open, as if every other capture had vanished. Your captures were never lost — Sealshot keeps a searchable list of them, and when that list had to be rebuilt from scratch (the first run after turning encryption off, for example) the strip showed nothing until the rebuild happened to finish and something else nudged it. Restarting Sealshot was the only way out. The strip now reads straight from your captures folder whenever that list is empty, and refreshes itself the moment the rebuild finishes.
• Fixed: the capture crosshair and magnifier were missing when the overlay first appeared, until you moved the mouse.
• The capture crosshair tracks the pointer more smoothly, especially on Intel Macs and on displays running a scaled resolution. The overlay also drops about half as many frames as it did, so the whole capture screen feels steadier while you pick what to grab.
• Point at empty desktop in the capture overlay and the whole screen highlights — click to capture the entire display. Previously nothing was highlighted there and clicking did nothing.
• Picking what to capture is steadier. Moving the pointer across the screen no longer lights up every window it passes over — a window highlights once you settle on it, so the overlay stops flickering on the way to what you wanted.
• Scrolling to widen or narrow the capture selection is smoother. One notch now moves one step instead of racing through everything under the pointer, and the box grows and shrinks in one continuous motion rather than lurching.
• Fixed: Remove Background sometimes left the editor showing the original image. The cutout had actually been made — the thumbnail in the strip showed it, and switching to another capture and back revealed it — but the canvas itself didn’t refresh until something else happened to redraw it.
• You can drag captures out of the Library again — to Finder, to another app, or onto a collection in the sidebar. Dragging a Library tile or row had stopped doing anything at all, in both grid and list view; only the editor’s recent strip still worked. Dragging one of several selected captures brings the whole selection, as it does in the strip.
• Dragging several captures out of the editor strip at once no longer prepares every file twice. Sealshot used to export each capture the moment you picked the group up, throw those files away, and export them again when you dropped — which also left a decrypted copy of each one behind in the system temp folder, even if you never dropped anything. The files are now written once, after the drop.

Live Capture

• Right-click a window in a Live Capture and you can now Export This Window… straight from that window’s menu, instead of selecting it first and going to the empty-canvas menu. It always saves the window you clicked.
• The empty-canvas version of the command is now called Export Selected Window…, so it’s clear which window it writes.

Privacy & Security

• Turning on Enhanced Security now clears the old plain search index straight away, instead of leaving it until the first encrypted save. If Sealshot was interrupted in between, that file could survive holding text read out of your captures — and a locked Sealshot would still search it. It is removed up front now, and a locked Sealshot refuses to read one even if it finds it.
• Fixed: with Enhanced Security locked and the trial expired, pressing a capture or record shortcut opened Settings over the lock screen. Locked now means locked — Settings stays shut until you unlock.
• Instead, Sealshot brings up the lock screen and explains that the trial has ended and new captures are paused. Unlock from there and Settings opens on the License page, so activating a license is two clicks from the shortcut that was blocked.

Welcome tour

• Fixed: dragging the welcome tour card to a second monitor made it disappear. It was still there — macOS just stopped drawing it, and nothing would bring it back, including Show Now. It now moves between displays normally.
• The tour card also stays in front of the editor window wherever you put it, and no longer jumps about when you drag the editor between monitors.
