Math & Science ⇒ chemmacros support

[spqr]

Hi everyone,
I am using TeXShop(v3.62) on MacOsX and I have some trouble using the chemmacros package.

Here is the result during the compilation:

Obviously the command on line 34 is not understood but I do not know what to do to fix this.
Do you have any idea?

Thanks a lot for your help!

You are trying to use a really up to date package with your very old distribution. A complete update to 2016 would be in order.


On a different matter: I am interested, why did you choose your name that way?

[spqr]

Hi,
I had updated TexShop but did not took care about TexLive... I will update this very soon and keep you in touch.
My username is linked to my first name (Roman).
Best,

Hi Roman,

welcome to the forum!

Ah, it's Senātus Populusque Rōmānus.

I guess it's MacTeX that you use. Maybe it cannot be updated as it's a pretty old version. But you could install MacTeX 2016 over that 2009 version.

Hello,
thanks a lot. An upgrade of MacTeX solved everything. Just need to learn how to use correctly this package now

Best,

Spqr

There's a good chemmacros manual.

Luckily, the author of chemmacros, Clemens, is a member and moderator here in the forum. So if you have a question that isn't answered in the manual, just ask here.
