The Mac version in particular has a lot of issues especially with Unity. It's definitely a lot better than MonoDevelop was. I have never used Rider but I have a long history of using another JetBrains product, IntelliJ, in a professional setting for around 8 years. I've only ever used Visual Studio for Unity.Reproduced with: 2018.3.0b3, 2019.1.0a2 Could not reproduce on earlier versions - was not able to decompile same two Symbols files in Rider. Expected result: Editor does not crash Actual result: Editor crashes. Attach Rider to Unity process and enter Play Mode through Rider.
