Travis CI OSX MacOS build speed

less than 1 minute read

Travis-CI MacOS builds (denoted osx in .travis.yml) emerged from beta in April 2013 using cloud-based Mac hardware. As this service became popular beyond iOS developers using it for Objective C builds, the amount of free service offered for MacOS builds became increasingly constrained. In January-March 2018, additional Travis-CI resources were progressively brought online, completed in March 2018. The new speed for Travis-CI OSX builds is incredible! The Travis-CI osx builds are now almost as fast to start as Linux.


Free users are concurrency constrained to two MacOS instances and five Linux instances. MacOS builds count against the total concurrency limit of five for free users. osx build backlog graph in red. osx build backlog graph for 2017.


The Travis-CI status panel shows that the MacOS backlog since March 2018 is typically near zero like the Linux builds. Before 2018, the OSX build backlog could be in the hundreds or thousands of jobs–this is no longer an issue. The Linux backlog typically stays at or near zero.

Paid customers should also experience short wait times of a minute or so for osx builds.
