Rawrr error on MacOS 15.7

[AharoniLab]

Hi,
I'm having a problem running 'rawrr' on my mac. following a completely smooth install, I get the following error with the demo data:

`> sampleFilePath()
[1] "/Library/Frameworks/R.framework/Versions/4.5-arm64/Resources/library/rawrr/extdata/sample.raw"

readFileHeader(rawfile = sampleFilePath())
sh: /Users/gabbiano/Library/Caches/org.R-project.R/R/rawrr/rawrrassembly/osx-x64/rawrr: Permission denied
Error in if (rvs != "No RAW file specified!") { :
argument is of length zero
In addition: Warning message:
In system2(exe, stdout = TRUE) :
running command ''/Users/gabbiano/Library/Caches/org.R-project.R/R/rawrr/rawrrassembly/osx-x64/rawrr'' had status 126`

Error could be related to:

`> list.files(rawrrAssemblyPath())

[1] "rawrr"`

Do I need to compile directly from source or can the package function out of the box also on a Mac?
BTW , a parallel install of the same version on Windows10 is OK and the package performs really well!

Hi, sorry for the late reply.

It does work for me on macOS 26.2. Have you recently executed rawrr::installRawrrExe()?

Can you check the output when you run:

~/Library/Caches/org.R-project.R/R/rawrr/rawrrassembly/osx-x64/rawrr --version

For me the version is 1.17.2.

If that does not work, maybe you could try to delete the folder /Users/gabbiano/Library/Caches/org.R-project.R/R/rawrr/rawrrassembly and run rawrr::installRawrrExe() again?

One thing to note is that it does not execute the reader natively on aarch64, but it runs with Rosetta x86_64 emulation because Thermo's RawFileReader library is not compiled for ARM.
