Hello everyone,

We are aware of the signing issues on macOS. All TeXmacs DMGs are signed with a CNRS/Sectigo key. However, it appears that on newer macOs, Apple does not accept DMGs unless they are signed with an Apple certificate.

We are currently in discussions with the CNRS to obtain an Apple developer account, which would allow us to sign the DMGs with an Apple certificate.

Best regards,

Liza

Dear all,


the dmg and the app is not signed correctly. Instead of an Apple certified key, the key is certified by other CAs. MacOS will only accept Apple certified keys for the for pay developer program.

Regarding the information that Massimiliano gave: with Sequioa Apple changed the security model. Right-clicking is not possible anymore, instead you have to go to system settings now: https://developer.apple.com/news/?id=saqachfa

Somehow my mail about this from two weeks ago, did not make it to the list.

Yours,

Ingolf

Hi Liza,

Thank you for your work on TeXmacs.

Let me tell you, that I was not able to install TeXmacs on my iMac Apple M3 running Sequoia 15.3.
I allowed to open the *.dmg with special security options.
But it refused to open the app. So: no success.


what does this means? What happens when you try to open the app. Also, sometimes double-click the first time is inhibited for security reasons: one should right+click and select Open, and there she is given the possibility to override the “quarantine” state.

Q: is there a possibility to install your TeXmacs version e.g. via home-brew?

BTW I had no problems to open and run MOGAN fork and also LiiiSTEM fork.
Both apps installed without any problems and work wonderful.
So I would like to ask: what ist the difference w.r.t. the apple acceptance of the *.dmg’s?

PS : And I have also the best experiences to work with Scheme s7 (Goldfish) with MOGAN. I tried many examples from the books EOPL, SICP, SAP (Scheme and the Art of Programming) and SoC (Schematics of Computational/Manis & Little) or ’Concrete Abstractions' (Hailperin et al.).

Best Wolfgang
