Certainly. For the forum, we have more room than the email form, so I would include enough detail to make the report useful to Garmin engineers and recognizable to other affected users.

Garmin Express 7.29.3.0 on macOS 27 — Garmin Connect and Tools & Content buttons do nothing
Post:
I am experiencing a Garmin Express UI problem on macOS 27 with Garmin Express 7.29.3.0 and a Garmin Instinct.
Garmin Express itself is functional in several respects: it recognizes the Instinct, I can sign into my Garmin account, and synchronization completes successfully. Activities uploaded by Express appear normally in Garmin Connect when I open Garmin Connect directly in a browser.
However, the Garmin Connect and Tools & Content buttons in Garmin Express do nothing when clicked. There is no error message and no visible response.
I have done the following troubleshooting:
- Changed the default browser from Firefox to Chrome — no effect.
- Tested
open https://connect.garmin.com/in Terminal. This correctly opens Garmin Connect in Firefox, so macOS URL/default-browser handling works.- Completely uninstalled Garmin Express, including its preferences, Application Support files, and caches.
- Restarted the Mac and downloaded and installed a fresh copy of Garmin Express 7.29.3.0.
- Signed in again and synced the Instinct successfully. The same buttons remain nonfunctional immediately after the clean installation.
I also examined the macOS unified log while reproducing the problem. At approximately the time of the button action, Garmin Express repeatedly generates the following CoreUI error/fault:
CoreUI: -[CUICatalog initWithName:fromBundle:error:] unable to find a bundle 'NSBundle </Applications/Garmin Express.app> (loaded)' with identifier 'com.garmin.renu.client'I checked the installed application and confirmed that both its Info.plist and code signature identify it as
com.garmin.renu.client(TeamIdentifier=72ES32VZUA).Network communication appears normal, and Garmin Express Service successfully completes HTTPS requests. The watch continues to sync correctly.
Because Tools & Content is also nonfunctional, this does not appear to be simply a browser-launching problem. A complete clean reinstall also did not resolve it.
I understand that other users have reported nonresponsive Garmin Express buttons after moving to macOS 27. I am posting this as a new report because the problem is still present with Garmin Express 7.29.3.0.
I have already submitted this issue to Garmin Product Support through the email form. I can provide Garmin Express logs and the relevant macOS unified-log output if Garmin staff would find them useful.
