My initial thought was just that with all the API </div><div>changes going on and me using a more recent version of macOS for the build than CRAN does, </div><div>it would not surprise me that, at some point, something</div><div>had changed in macOS, causing this “user-interface-only” crash.</div><div><br></div><div>Anyway, so as not to bother you further, thanks again for the help. I am good for now, </div><div>and if I figure out what has to be changed in my configuration to make it work again, I will post it.</div><div><br></div></div><div><br></div><div>Kind regards, </div><div><br></div><div>Sebastian </div><div><div><br><blockquote type="cite"><div>On 25.

It is unclear from your description how you built R (there are several variants such as framework install vs "unix"-style install and they are incompatible).

So I started building <br>R from source following https://stackoverflow.com/questions/75595875/how-do-i-build-r-from-sources-on-macos<br><br>Adapted to my system, this worked surprisingly well, so I kept drawing R-devel from the SNV server on a regular <br>basis and built it from the source. However, it stopped working in mid-August. In a nutshell: <br><br>- I can build R-devel from the source without any issue flagged, and when started in the terminal, it works as expected.<br>- However, it crashes reproducibly when trying to load a package in RStudio (stable/nightly build) and the R GUI (always the latest version) <br>terminates the R session on start. Error messages in the console I get read as follows: <br><br><blockquote type="cite">R GUI: Termination Reason: Namespace SIGNAL, Code 11 Segmentation fault: 11 <br>RStudio: Exception Type: EXC_CRASH (SIGABRT) -> /usr/lib/dyld 0x0 - 0xffffffffffffffff ???

however, if it works <br>For all others without, then the error must be on my end, and I have to keep digging further. <br><br>- Tested systems: M2 -> macOS 14.5 to 15.0 with the Xcode on always the latest version available at the time.<br>- SNV: Always the latest check out <br><br><br>Kind regards, <br><br><br>Sebastian Kreutzer<br><br><br><br><br><br><br><br><br><br><br><br><br></blockquote></div></div></blockquote></div><div><div dir="auto" style="caret-color: rgb(0, 0, 0);
