Unity 5
Unity 5
Hi, for your MacBook Air from mid-2011, you can try installing Unity 5 by downloading the official Unity installer from their website. Ensure you have enough storage space. Once installed, launch Unity and check the system requirements—typically it needs at least a recent macOS version and a decent processor. The "standard assets" folder is usually sufficient for basic development. If issues persist, consider updating your OS or using a compatible older version of Unity.
Your laptop should manage this task. I believe you're using macOS, not Windows. It shouldn't be installed as a standalone app—check the Launchpad for its presence.
