Is the normal, default behavior for an CMD-R based Mavericks OS Recovery to always pull the image over the internet?
(I am not talking about a deliberate "Internet" recovery CMD+OPT+R)
Back story -- I just purchased an open box 2014 Macbook Air. It was nominally wiped and recovered with os 10.9.3 -- (although I also am pretty sure I am seeing the previous owner's name appearing as default bluetooth options (probably need to PRAM reset as well)).
In any case, I immediately booted again with CMD-R to perform a Full OS reinstall. It immediately let me know installation would take over an hour. Looking at the full logs, and my wifi logs, it spends about 15 minutes downloading "506 chunks", of what I presume is the recovery image.
The first time this happened, I figured it was doing so possibly because there 10.9.4 is now the current OS version, so perhaps it just does a simple check and downloads a new recovery image if the version has changed. I let it complete the full install by default.
However, for giggles, after it was fully complete with the install (fully default), I decided to perform another OS install. Interestingly enough, the same behavior, 15 minutes spent downloading the same 506 chunks.
I would have expected that the recovery image on the disc would be the primary means of recovery, with deltas possibly being downloaded. The behavior I'm seeing seems very "wasteful" OF bandwidth.
I'm just wondering the the prior owner did something that is permanently causing this behavior.
