With thunderbolt ports on very Mac why should storage be limited to internal devices?

[kstenerud]

Because they want you on iCloud. You can't even install the OS without an Apple ID and an active internet connection anymore.

[nizmow]

This is extremely false.

[kstenerud]

Which part? The iCloud part or the OS install part?

I just finished reinstalling Yosemite an hour ago after wiping the HD of a friend's new laptop. It would not allow me to get past the eligibility check until I logged in with a valid Apple ID.

[X-Istence]

Your friend may have had Find my Mac turned on. At that point the only way to get an OS installed on it is to have the original apple ID it was turned on under.

[kstenerud]

Nope. She never used it. It was the initial "determining the eligibility of this machine" phase where it asked me to log in (originally, this was to check that you'd indeed purchased OSX Lion, but the OS is "free" now). If "Find my Mac" is turned on, it won't even let you wipe the hard drive.

[astrange]

Sounds like you were using Internet Recovery. It's downloading the OS installer from the App Store - if you had install media it'd work fine.

Apart from being false this doesn't make sense. Apple put thunderbolt ports on the machines they sell. You're suggesting they included ports so customers wouldn't use them?
