bootmacmacbookmacososx-yosemite
I have Windows 8.1 and my another device is MacBook Air (Mid 2011). My MacBook Air’s OS didn’t startup and I unintentionally erased my MacBook HD partition. Now, I only could access my restore partition of my MacBook Air.
I have the Mac OS X 10.10 (Yosemite) from the Apple app store on my external drive, but I don’t know how to create a bootable flash drive to clean install the OS.
Is it possible or not?
Trim kext is altered in Yosemite. This is not relevant if you're using an Apple installed SSD. If you're using a DIY SSD, Trim support is tricky in Yosemite because of recent modifications to kext security management that affects Trim support. More about Trim Enabler for Mac.
About Trim in Yosemite In OS X 10.10 (Yosemite),
Apple has introduced a new security requirement called kext signing. (A kext is a kernel extension, or a driver, in Mac OS X)
Kext signing basically works by checking if all the drivers in the system are unaltered by a third party, or approved by Apple. If they have been modified, Yosemite will no longer load the driver. This is a means of enforcing security, but also a way for Apple to control what hardware that third party developers can release OS X support for.
Since Trim Enabler works by unlocking the Trim driver for 3rd party SSD’s, this security setting prevents Trim Enabler to enable Trim on Yosemite.
To continue to use Trim Enabler and continue to get Trim for your third party SSD, you first need to disable the kext signing security setting.
It is important to note that the kext-signing setting is global, if you disable it you should be careful to only install system drivers from sources that you trust.
Some drives work without Trim enabled: ZDNet on issues with Trim in Yosemite.
