    My 15" 2012 Retina Macbook Pro lags like crazy when switching desktops and opening applications. Screen also flickers.

    Had it repaired before but the issues came back. Geniuses said I was out of warranty so they just did a Software Repair.

    For proposed resolution, it says "Run ASD EFI and OS".

    Anyone know what that does and if it will help at all? I'm pretty sure its a hardware issue btw.

    sounds like they're doing only a software-level check and repair

    ASD EFI & OS is Apple Software Diagnosic, the EFI based version, OS is the Mac OS X based version. It's a long-form hardware diagnostic to determine hardware faults.

    ASD in itself doesn't do repairs, but it's often ran if you're trying to track down a hardware fault. That being said, within MRI, the NetBoot environment from which ASD is launched does have some repair elements in it.
