Hi, I’m very new to the freefem++ program, and I met some problems when trying to use it on a macOS. To be specific, I can not load “bem” correctly and the following error occurs: Load: lg\_fem lg\_mesh lg\_mesh3 eigenvalue 1 : load “bem” Load error: bem fail: dlerror : dlopen(/usr/local/ff++/mpich3/lib/ff++/4.7-1/lib/bem.dylib, 2): image not found list prefix: ‘./’ ‘/usr/local/ff++/mpich3/lib/ff++/4.7-1/lib/’ list suffix: ‘’ , ‘.dylib’ current line = 1 Load error : bem line number :1, bem error Load error : bem line number :1, bem I do not know how to deal with this and I’m looking forward to your help. Thank you so much for reading and for your help Best wishes, Yan ![WX20231028-172824@2x](https://canada1.discourse-cdn.com/flex030/uploads/freefem/original/2X/9/910d7d66dfca2a2f4365b78199c63076ee5cdc5f.png) ---

Hi, I would also like to know if this problem has been resolved on macOS (I have the exact same error message). As of the recent FreeFem++ update I can’t even access ff++ with the \>\> open contents (FreeFEM++) → Contents → ?. Thank you for yourk kind support. Best wishes, Matic
