Yeah, I probably should have waited, but I installed macOS 26 Tahoe on my main Mac last night.
Glyphs generally runs exactly as before, except I’m noticing frequent beachballs and delays where the app becomes unresponsive for a second or more. It always catches up, doing the actions I was trying to do very rapidly, as if they were waiting in a queue during the delay. It happens especially when I’m zooming or panning with the mouse, especially with edit tabs that contain a lot of text. Sometimes it seems like it’s every time I do a mouse action.
It’s quite possible it’s unrelated to the OS upgrade, or maybe the latest cutting edge version of Glyphs, but it correlates.
With the new “liquid glass” effects, I can imagine that the GPU load is greater than past versions of the OS, but given that I have a fairly high-spec Mac, it doesn’t seem that likely.
FWIW, I haven’t noticed anything similar in other apps so far, but I’ve been using it for less than a day.
I’m on an M3 Max MBP, macOS 26.0, Glyphs 3.4 (3427)
Anyone else seeing this?
Edit: One other thought: Maybe it’s happening when it’s doing the autosave?
I am running an M4 mini with Sequoia 15.6.1 and no problems with 3425 Glyphs. I do have great problems printing, however. It seems my Xerox printer will not support Sequoia;-)
It doesn’t seem to be happening anymore, so I suspect it might have been Spotlight, as suggested, or something else related to the OS upgrade. A bit weird that it only seemed to happen in Glyphs, but all appears okay now.
Just to circle back on this… It turns out that the Huion tablet driver I had on my system (20.0.1.58) isn’t compatible with macOS 26. Once I removed it, the UI delays I was getting, which would come and go, and not just in Glyphs—that’s just where I first noticed it—, completely went away. Glyphs seems to be working fine in the new OS.
After several sessions with Apple support and eventually bringing it in for repair, it turned out that I needed to wipe my drive and reinstall the OS and software from scratch. Turns out, migrating from Time Machine backups, one machine to the next and one OS to the next for over ten years is a bad idea.
Since I did this a couple of weeks ago, my Mac has been running better and faster than it did when it was new.
Nothing to do with Glyphs or Tahoe, but might be instructive to some.
Hi Mark, I just bought a new Mac M4 about 6 months ago and built my system from backup just as you mentioned. What I noticed is that the finder gets confused. When I do a search from the finder, my Mac is not as good at finding stuff as it used to be. I have most of my files on a new 8 TB external drive.
Do you recommend that I totally rebuild my Mac from scratch and reload all the software from scratch?
I’ll second Georg’s suggestion. I’ve had this problem periodically and resetting Spotlight always fixes it. Why it goes wrong in the first place, I don’t know.
It’s pretty simple to do. Go to the Spotlight settings and exclude your startup drive, close the settings app, wait for a minute, and then go back to Spotlight settings and remove the startup drive from the excluded list. It takes some time for Spotlight to rebuild its index, but it should fix it.
