Application fails to create socket file during first launch after installation

[Arus1]

The issue is related to QLocalServer which fails to create socket file during the first
launch after installation on Mac OS.
But after restarting this functionality works properly.
The difference is that just after installation the value of TMPDIR environment
variable (where the socket file is created) is different
(e.g. /private/tmp/PKInstallSandbox.2CPTHs/tmp) than after restarting the
application (/var/folders/gn/65zr8lj978d9z0ffk202rnyc0000gq/T/).
What can be the reason of the issue?
Thanks in advance.
