The upper left key (left of "1") doesn't work on macOS for some layouts, specifically those that use the ISO physical layout. This is a regression caused by this upstream commit: https://github.com/TigerVNC/tigervnc/commit/0c15866f0c86402016e55eeb7c044eb2e6cd95f5 It was pulled in to ThinLinc in bug 7158 for 4.9.0.

*** Bug 8414 has been marked as a duplicate of this bug. ***
Tested the macOS client on 6 different ThinLinc versions - 4.9.0 (worked) - 4.10.0 (blank client, bug 7539) - 4.12.1 (worked) - 4.13.0 (worked) - 4.14.0 (bug started showing) - 4.17.0post_3682 (fixed) Since the bug didn't show until 4.14.0, the diagnosis that was made in this bug is wrong. Marking as duplicate of bug 8414, which describes the issue more correctly. *** This bug has been marked as a duplicate of bug 8414 ***
