The number of days between purchasing my 2018 MacBook Pro and the spacebar starting to get stuck?

Feh.

Hate to hear this. Had high hopes that the MacBook keyboard issues were behind us. I will add that my son’s machine (a 2017 model purchased earlier this year) has the same issue.

Check out the article URL, a nice little side comment in those last 13 characters.

One final note: Check out this video showing a warranty-voiding fix to the spacebar problem. Fascinating, but definitely not something you want to try at home.
