.gitignore is not being created after ignoring files on Mac

[Manuel Hevia]

Hello, I am new to Sourcetree and I am following a tutorial that tells me to ignore some files and then double click on .gitignore but it doesn't seem to have been created. Or at least it is not among the remaining files. Do I need to do something else or look somewhere else? Thank you in advance.

Hi! 

you need to create a manually that file. (Because that file is just instruction of excludes for your repo) 

https://git-scm.com/docs/gitignore

Also, you can put any filter to exclude tracking.
