If you are an IT rookie they will tell you what you want to hear. Just try one time to ask a question about the SSL problem from Feb 2015, and they do an about face. In August 2015, my MacBook got hacked with the same SSH Cross Site Scripting using the Man-In-The-Middle. When I called Apple, they were dead silent. Dissembling, misdirecting, obfuscating, worst of all no help. Denied it had anything to do with "Apple" but refused to offer even the simplest of suggestions on how I can prevent it in the future. How do I know if I have the SSL fix in MBP? Well I can't because the SSL problem was in iOS. I went to the developers website and found the same iOS SSL is part of Yosemite. So again, misdirection and lies.

When I tweeted — from my secret social-media account used to hide my identity as a reporter — for help about Spectre and Meltdown, Apple responded a short 10 minutes later. The company also included the correct information (update macOS on your Mac, and you're OK), along with a link to documentation on Apple's site that explained the situation in greater detail.
MacBook Air components are officially non-user-replaceable, though third-parties do sell upgrade kits for the SSDs. The flash memory and battery are enclosed within the casing, with RAM soldered onto the motherboard. The flash memory, difficult to access, has a 128 MB cache and a mSATA connection (updated to a proprietary PCIe interface) to the motherboard.
Some counterfeit and third party power adapters and batteries may not be designed properly and could result in safety issues. To ensure you receive a genuine Apple battery during a battery replacement, we recommend visiting an Apple Store or Apple Authorized Service Provider. If you need a replacement adapter to charge your Apple device, we recommend getting an Apple power adapter.
