Waiting on  crbug.com/580152  before landing https://codereview.chromium.org/1938113002/ on this issue (as per discussion in CL).

Please clarify why this is a blocker? We don't run Chrome on 10.8 or older any more, and we link against the 10.10 SDK, so there shouldn't be anything that prevents you from dropping unecessary Mac frameworks.

*Whoops, to clarify, I meant https://bugs.chromium.org/p/chromium/issues/detail?id=580152 should not block you.

My mistake. Please clarify ask for changes to proposed CL (in CL comments).
