Mac OS X 10.11.6 installed 6.0.3, updated the package to 6.1.2, stopped running tsh, teleport, ...

The question is, how do they update correctly on a Mac?

I guess these are compatibility issues 10.11 and 10.12 in specific Symbol called _clock_gettime, which did not exists in OS X <10.12
maybe you stopped supporting 10.11, unfortunately I did not find in the release notes that 10.11 is not supported

`macpro% tsh
dyld: lazy symbol binding failed: Symbol not found: _clock_gettime
Referenced from: /usr/local/bin/tsh
Expected in: /usr/lib/libSystem.B.dylib

dyld: Symbol not found: _clock_gettime

Yes, this looks like the minimum version of MacOS supported by Golang changed at some point.

Here is a table comparing teleport/tsh version to Golang version:

Teleport version	Golang version used
7.x	1.16.2
6.x	1.15.5
5.x	1.15.5
4.4.x	1.14.4
4.3.x	1.13.2

If you find that newer versions of tsh aren't working, you can try using one of the older ones.

I will see if we can get some documentation added relating to minimum MacOS version supported.
