Intellisense not working on Mac in VS Code nor in VS Community

[Alex_May]

I have no intellisense on VS Code or VS Community. It basically means I can’t work on the mac at the moment.

VS Code complains about .net 4.7.1 which is a Windows binary I think, so why it’s even asking for it on Mac is a mystery - tried fixing it by downloading latest .net Core but that didn’t fix it. Tried rebuilding the project, tried hacking the project to point to .net core instead of .net framework - no joy.

VS Community just randomly stopped working - not sure if it was some update somewhere but now it gets all the code formatting wrong (keywords change colour half way through; single line comments turn the next line green; newline doesn’t tab in to the correct indent; etc) and there’s no intellisense at all. I can’t find anything in the app that will help me find out what even went wrong.

I’m so sick to the back teeth of these problems which I’ve had on and off for my entire time working with Unity on the Mac.

I get that these are not easy problems to solve, but I am really sad and frustrated here.

I’m using 2020.1.11f1 on macOS 10.14.6 Mojave.

You know what, fuck it. I’ll use a different engine. Too many problems over the years with this damn software.

This may help you with intellisense problems:

Intellisense Not Working with Visual Studio (Fix)

Likely, if you have appeared here to this page you are having the problem I had for the past hour or so. Intellisense is not working in Visual Studio. Well lucky for you, I figured out the solution to fix this issue after searching the entire web. So you don’t have to search the web anymore, I will tell you how I fixed the issue. Step 1: Close Visual Studio Step 2: In Unity, go to Edit < Preferences < External Tools (left part of the Window) Step 3: In External Tools go to the part that sa…

Also, try update the VSCode package inside of Unity: Window → Package Manager → Search for Visual Studio Code Editor → Press the Update button

Also, this: No suggestions in Vscode

[Alex_May]

Something in one of these threads eventually worked for VS Code. Thanks Kurt-Dekker.

[Alex_May]

Nope, it’s gone again.

[Alex_May]

Downgrading VS Code C# extension to something below 1.23.0 worked for me.

No suggestions in Vscode

EDIT: thank you so much, downgrading to 1.23.0 didn’t actually help, but going a little lower helped.

[steelyjim]

I renamed my project and intellisense stopped working.
Use Command-Shift-Period to show hidden files in your project folder
Delete any VS related files/folders
Voila.

Thanks a lot. This fixed my problem after trying many solutions for hours.

[Melanie_MICA]

If you are on a Silicon M1 or M2 processor Mac Apple…
To use Visual Studio Code and to get intellisense with it, you gotta delete the VS Code package from your Package Manager in every project. Then you also need to update the Visual Studio (not Code) package in your project. Then you gotta go to Unity Settings and point your external tools code editor toward Visual Studio Code.
Seems weird to install the VS package and actually be using VS Code but that’s how Microsoft managed to make it work at the moment!
