Bug ID: 47944
           Summary: Wine64 tries to change permissions in /private/tmp/
                    that fails on macOS 10.15 Catalina
           Product: Wine
           Version: 4.17
          Hardware: x86-64
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown

          Reporter: [e-mail]

Hello,

We develop Windows applications that work on Linux and macOS thanks to Wine.
Those are 64-bit applications so we thought that we wouldn't have major
problems when switching to macOS 10.15 Catalina.
We can indeed run the applications with wine64 (Wine 4.17).

But they freeze when they try to display an html browser (CEF, Chromium
Embedded Framework) with these errors in the console:
0162:err:virtual:map_file_into_view failed to set PROT_EXEC on file map, noexec
filesystem?
0162:err:virtual:virtual_map_section mapping 0x4db0000 1000 000000000 failed

We discovered that it fails on a fresh install, but it works if we disable SIP
(System Integrity Protection).
We can indeed read this in the system log :
kernel (AppleSystemPolicy)
Library load
(/private/tmp/.wine-1604910507/server-1000004-86265/anonmap.7vgk04) rejected:
library load disallowed by system policy

So is there a way to tell Wine not to use /private/tmp but another folder for
temporary files?

Regards,

Michel Terrisse
