If you're a Mac or Linux user looking forward to the retail release of the Oculus Rift virtual reality headset, it looks like you're going to have to wait longer than PC users.

Chief Architect at Oculus Atman Binstock announced last week that the company is pausing development on Oculus Rift support for those operating systems.

"Our development for OS X and Linux has been paused in order to focus on delivering a high quality consumer-level VR experience at launch across hardware, software, and content on Windows," Binstock said. "We want to get back to development for OS X and Linux but we don’t have a timeline."

Last week, Oculus also revealed the recommended PC specifications for the headset:

• NVIDIA GTX 970 / AMD 290 equivalent or greater
• Intel i5-4590 equivalent or greater
• 8GB+ RAM
• Compatible HDMI 1.3 video output (required)
• 2x USB 3.0 ports (required)
• Windows 7 SP1 or newer (required)

Joining Rift next year will be Sony's PlayStation 4 headset, Project Morpheus. Meanwhile, the ViveVR headset, from Valve and HTC, is due to launch later this year. Pricing for both headsets has not been announced.
