Can not reproduce on the *official* R release (i.e. the binary version provided by R): ```r R version 3.6.1 (2019-07-05) Platform: x86_64-apple-darwin15.6.0 (64-bit) Running under: macOS Mojave 10.14.6 Matrix products:...

Also checked with the very latest `MSnbase` (2.11.13) which was pushed to day to bioc: all OK. I hope this was some temporary problem.

replicating the error is pretty tricky - also because at present I get it on files that I'm not allowed to share... but a small update in between: I was...

Info on my setup: I'm running the R installed through *homebrew* - it's not the *official* R version, but that one has the problem that I can't assign/link a debugger...

@korseby , you suggest then to install again the command line tools (no idea why it's not being updated...) and then re-install R and try again?

Hm, didn't help unfortunately: ``` f04870_Prot_04_F04.mzML Process 67730 stopped * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x1a7717a28) frame #0: 0x000000019898dd14 mzR.so`pwiz::msdata::id::translateNativeIDToScanNumber(pwiz::cv::CVID, std::__1::basic_string const&) + 260 mzR.so`pwiz::msdata::id::translateNativeIDToScanNumber:...

Did that - didn't help. Also, I get the same error on a different Mac.

Note: I by chance could get rid of the initial error reported in this issue: ```r isMSnbaseFastLoad() FALSE for (i in 1:20) { chr

Thanks for the feedback @korseby - means I will revert the default for macOS in `MSnbase` and `Spectra` (i.e. enable the *fast load* also on macOS).

Hi @yufree , thanks for reporting! I can confirm that I get the same issues (again) with `setMSnbaseFastLoad(TRUE)` on macOS 12.1 Monterey. Setting `setMSnbaseFastLoad(FALSE)` fixes it again. This seems to...
