Looks like macOS failed due to test-browser failing as per https://ci.brave.com/job/brave-browser-build-pr/job/PR-9506/2/execution/node/615/log/

05:24:22  [  FAILED  ] BraveRewardsBrowserTest.NotVerifiedWallet, where TypeParam =  and GetParam() =  (6114 ms)
05:24:22  [539/539] BraveRewardsBrowserTest.NotVerifiedWallet (6339 ms)
05:24:22  1 test failed:
05:24:22      BraveRewardsBrowserTest.NotVerifiedWallet (../../brave/components/brave_rewards/browser/rewards_service_browsertest.cc:2326)

This a known intermittent issue so not blocking uplift.
