With the new pipeline, all tests have to wait on Mac OS X Workers to install their deps

With the new version of the pipeline, literally every single test run has to wait for the resource limited pool of Mac OS X workers to have one worker free to install their deps. I've waited multiple times 30+ mins just to wait for deps to be installed :/

Worst! Now if one of the runtimes runs out of space (which happens often), all the other runtime tests get stucked waiting for that one

Error: ENOSPC: no space left on device, write

This is already tracked on the CI work that @mburns and @hugomrdias are doing.
