Hi all,

with MacTeX 2020 on a newly installed Mac, I have the problem that ConTeXt doesn't work anymore:

$ context file.tex
mtx-context     | warning: no format found, forcing remake (commandline driven)
[…] snip lots of lines
resolvers       | formats | changing to format path '/var/folders/rj/hfjmjx796q102y4v23vh038c0000gp/T/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/formats/luatex'
resolvers       | formats | unable to change to format path '/var/folders/rj/hfjmjx796q102y4v23vh038c0000gp/T/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/formats/luatex'
mtx-context     | error, no format found with name: cont-en, aborting
system          | total runtime: 5.315 seconds

The ConTeXt docs say that I should run mtxrun --generate, which seems to run successfully, and context --make, which finishes with the same „unable to change format path“ error (I believe this is what context automatically does when compiling my file, hinted by the „no format found. forcing remake“ message). I tried explicitly running context --make cont-en which yields the same result. The given path does exist on my hard drive.

I don't even know if the „unable to change format path“ message is actually an error, but I have no other indicator of what goes wrong. The only line that explicitly says „error“ is the one I get when trying to process the file.

Interestingly, I have another Mac where I upgraded from MacTeX 2019 to MacTeX 2020 and everything works there.

I made sure that everything is up-to-date with the TeX Live Utility.

How can I fix this problem?

Regards,
Felix
