Since Update to Mac OS 10.13.4 Most Files in Snagit 2018 Library Don’t Show Previews

  • Updated 6 months ago
Since the latest Mac OS update to 10.13.4, most files (still shots) in the Snagit 2018 library no longer show previews. It's the same in the Finder—no preview. However, for some of the same files there is a preview in the Recents tray of the editor. The issue is the same on both of my laptops. Anyone know of a fix or is this a known issue? Thanks.

Hi,

So sorry about this! The 10.13.4 update appears to handle file previews a little bit different than it used to. We are working on a fix, unfortunately we're not aware of any workarounds at the moment.

I've updated both iMac and MacBook Pro to 10.13.4. All previews show just fine.

Are your drives all SSD (as opposed to fusion or traditional spinning drives)? Mine are SSD and were updated by default to the APFS when I upgraded to High Sierra. I’m wondering if that may play a part in the issue.

I bought my MacBook Pro in Feb 2017 yes it has a 1TB SSD an 16 GB Memory. And the Library files showed up perfectly up until I updated to 10.13.4. So the Drive ran on the old file system until I installed High Sierra 13. And SnagIt worked Perfect up until the 13.4 update.

None of the Library Previews shows up as images  just generic icon with snagit symbol. Use 13.4.

I have this issue too. I am running 10.13.4 and SnagIt 2018.1.1.

I think I was having this issue before upgrading to 10.13.4 this morning. When I scroll through my Library, it's actually removing preview images and turning them into the generic "S" icons. This is making it very difficult to find screenshots.

If you don't have any markup (arrows, highlights, etc.) in your images you won't see any issues.

Unfortunately, most of the images I’m experiencing the issue with do not have any markup.

Yes and yes. SSD - yes. Now I scrolled down a bit in the library and, yes, the "good" ones have no markup. So the ones showing the Snagit icon must be marked up. :)

I’ve since noticed that in addition to the no-preview issue, when I capture then copy and paste into my Sketch app, the image appears faded. I tried a couple of other screen captures that did not use Snagit and they were fine, so this is an additional issue that is likely related since it was not happening prior to the upgrade.

I upgraded from 10.13.3. If it helps to know, I’m using Sketch 49.2. Thanks.

Thanks for the info. So there is a workaround that you can do for now. The washed out issue only affects .png files, so you can change your drag and paste format to jpg (or TIFF if you need transparency) and that seems to work as expected.

Hi 

I just got an update for Sketch (49.3) that appears to fix the washed out issue! Let me know if it works for you as well.

I just updated Sketch and it did fix the washout issue. Thank you. Apparently, you weren’t the only ones the Apple update affected. I appreciate your timely responses.

Glad that's working again! I'll report back once we have a fix for the library thumbnails.

I do not have Sketch. I have nearly always been set to .png. If I drag one of the icon only snag formatted items to the Desktop, I get the shot showing clearly. All of the few I tried were marked up as someone mentioned previously. For me, this is not a show stopper -- just an annoyance.

I'll note its only in the Library file that has this issue the group file in the Preview pane just below drawing area, works just fine.

Hi,

We have fixed this issue in our development builds, but we're still working on finalizing the other items in the release. I will report back when the update is available. Thanks for your patience.

Hi all,

We just released a 2018.1.2 update that has a fix for this issue. Note that you maybe have to reboot your machine for the thumbnail fix to take effect.
Alternatively if you're comfortable with Terminal, you can open up a window and run qlmanage -r to reset macOS's QuickLook cache.

Ran the 2018.1.2 update, restarted the Mac and still had generic icons in library. Up popped a message for a 4.1.9 update. I ran that and restarted the Mac. Still have the same generic Snagit icons in the library. (Mac is on 10.13.4)

So you have Snagit 4 and Snagit 2018 installed? Seems like the system might be grabbing the old QuickLook plugin from Snagit 4.

I would swear that I had already trashed 4 but there it sat. Trashed it and various plists, etc., associated with it. Quit and restarted Snagit and all is OK... no generic icons. Sometimes that extra set of eyes is very valuable. Thank you.

With the release of the 2018.1.2 update today, it appears that the issue has been resolved unless anyone affected posts otherwise. Thank you.

I just installed Version 2018.1.2 (90438) on my MacBook Pro that is running High Sierra 10.13.4 (17E202).  I still have the same exact problem with random thumbnails showing a large blue S

Hi,

Have you rebooted your computer since installing? That seems to be needed in some cases. If it's still happening after a restart, then I would open a ticket with our Tech Support team and they can help you out.

One other thing to check, if you have a copy of Snagit 3 or 4 installed, macOS sometimes grabs the plugin from the old version instead of the new one. If you remove the old copy of Snagit (and maybe reboot again), the thumbnails should start to work again.

figured it out, I still had the old version installed.  You must remove it in order to fix this with the new 2018 version.
