Parallels RAS Core 21.2.2, build 27429, released on 7 October 2026, introduces two improvements to time zone and input language handling.
The first extends time zone redirection to session hosts without the Remote Desktop Services (RDS) role. Remote sessions can therefore display the user’s local time zone—a useful addition for teams working across different countries.
The second improves input locale propagation during the session, particularly for languages that rely exclusively on an Input Method Editor (IME). It adds support for the server’s default IME, along with automatic showing and hiding of the legacy language bar for Chinese, Japanese and Korean IMEs.
To enable this second feature, configure the following registry value on the host where the session is established:
| Setting | Value |
|---|---|
| Key | HKLM\Software\Wow6432Node\Parallels\MemShell |
| Name | RedirectInputLocale |
| Type | DWORD |
| Value | 1 |
The RASInsider take: two focused improvements that can make everyday sessions more comfortable for international users. The IME enhancement should not, however, be treated as a general fix for keyboard mapping issues between macOS and an RDP client.
