# Which games are 64-bit compliant for Apple’s MacOS Catalina to present?

Cyan games that ***are***64-bit compliant with MacOS from Catalina to present:

**Firmament**
**Obduction**
**realMyst: Masterpiece Edition**
**Myst III: Exile**
**Riven: The Sequel to Myst**
**Myst: Masterpiece Edition**

Cyan games that *are not yet* 64-bit compliant with MacOS from Catalina to present:

*URU: Complete Chronicles*

*Myst V: End of Ages*

*Myst IV: Revelation*

**Note:** Cyan is working with Codeweavers, the developers who helped us update the games in 2018, to make the games compliant with Apple’s latest update requirements.

There is no ETA for when the update process will be complete. Thank you for your patience.
