I have already chosen to be a cook, and the ultimate ambition of a bartender cannot be fulfilled. Can you modify the other conditions? I want the characters to achieve all aspirations, which is very unfriendly to obsessive-compulsive players. Now can not go back to choose the branch, and can not complete the final ambition
Unfortunately, I think that is by design. Depending on your platform, you either need to research for cheats to be able to do this or a mod. It is the same way with all the careers that have you "choose a branch path."
Unfortunately once a career path is chosen, it is permanent.
For the aspirations, if you haven't chosen already, you should go for mixology. The mixology aspiration requires this branch but the masterchef aspiration does not specify a branch in the culinary career. You can complete it as a chef or a mixologist. Not having to choose seems a bit odd but I think that was an intended work around because we can't switch. I completed both aspirations with the same sim by choosing the mixology career.
If you use mods you can use mccc to reset the career track
If you own discover university you can get the degree for the chef branch of the culinary career and get into that career track mod free.
You can still join the Mixology branch if you have Discover University. You'll need to Sit In On Skill Class for Mixology eleven times to get a Mixologist Certificate. The Mixologist Certificate works like a degree to give you advanced job placement, higher pay, easier promotions, and more vacatoin days.
