If you prefer to use Chrome as your web browser, you might want to set the default browser on the Mac to be Google Chrome. And if you use Google Chrome Canary, you can set that as the default browser too.
Using Chrome as your default browser on a Mac is particularly advantageous for multi-platform users, since if you also use Chrome as the default in Windows, Android, Linux, and if you’ve also set Chrome as the default browser on iPhone and iPad, you can easily move your browsing session around any device or machine, regardless of the platform. This contrasts to Safari, which, while it’s an excellent web browser, is limited to Apple devices and thus is not usable by Windows, Linux, and Android users, and can’t share sessions, bookmarks, and tabs with those platforms.
