The cons are that it will reserve hard-disc space and also you wont' be able to format the full disc.
It will be generally faster as a procedure.
Note, that if you have enough hard-disk space in your mac, you could just split it into 2 partitions and do the above instead of using the flash drive. You will also have access to the disk utilities in order to format your internal drive if needed. Now you can boot your mac through the flash drive and can run Yosemite installer anytime. After installation, remember to also put a copy of the Yosemite installer on the flash drive.Īlso upgrade your macbook air to Yosemite. Format it with GUID partition and install Yosemite on it.

I paid a per-incident AppleCare call and they said they do not support non-internet recovery anymore and I have to take it to a care center to reinstall the OS for me(in the post laptop era, owner has no control of OS installation any more).

I want it to be possible from a placewith out internet as well.
Experimentation led to instability and the fastest way to get back is to reinstall the OS to a fresh start. recently, I was testing my client's app on it and made lots of changes to the OS settings. The main purpose of the Macbook Air is to use it on the road when i travel. Is this possible on these newer machines? What are the steps?
I want to reinstall the OS on the laptop without an internet connection.
