I’m in the final stages of preparing support for macOS and had an issue I’m unsure of how to solve. On my personal Mac, the build works fine - but on a school computer, it crashes the DAW immediately. My Mac: ![mac](https://global.discourse-cdn.com/free1/uploads/iplug2/original/1X/1a909ed079b8933d11848f8cc8492a658f1bea1f.jpeg) Other Mac: ![IMG_8437](https://global.discourse-cdn.com/free1/uploads/iplug2/original/1X/d2b37f016dd5adb8ba95716eac5f2e42ce736c47.jpeg) My first guess is that the OS difference is causing errors with some internal APIs or something - but I won’t be able to build the product on the school computer because it is not mine (is there a way to do it on mine?). This is the last thing I need to fix before release. Thanks for any help! Edit: I’ve ran `lipo` on the terminal to check whether the binary is universal and got this: `x86_64 arm64` - which should be universal…? ---

It might be because metal is not supported on that machine ---

The solution to that is to build using skia CPU mode, The instructions are on the wiki ---

Because the skia static library still contains the Metal backend, you still need to link against the Metal framework, e.g. > ---

Sadly I don’t think SKIA CPU is currently a viable option on macOS. Blitting on a retina screen is just too slow. I tried your plug-in and the UI crawls with Skia CPU.

Using IGRAPHICS\_GL3 instead of IGRAPHICS\_METAL may be an option, if you really must support this machine ---

Actually debugging SKIA CPU with your plugin I have come across a very strange behaviour. Somehow using a different bitmap for each knob is affecting the frame rate! ---

Hmmm, interesting. I just tested another product with only 5 knobs on a school computer and got a relatively usable frame rate compared to the other one. I suppose there’s a nice line in the middle between realism and performance, and performance is more important. I’ve been meaning to build a little framework for brand recognition using vector graphics anyway lol. Aside from changing the renderer to Skia, I also ended up creating @2x files for my assets and that fixed all of the crashing on the school Mac. I’m seeing pretty good results now, thanks for your work!
