![]() And affirmed again that it passed diagnostics. My immediate response was "DID YOU TEST THE WIFI CARD?" to which they said, YES. They took the computer in and called me a day later saying once again "It passed our hardware tests so we did a clean install and everything is working fine". I insisted that they trust ME over their POS (not talking about point of sale here) apple diagnostics tests. UPDATE: I finally took my iMac 27" into apple for the millionth time at the 4th store and told them I wasn't leaving until they diagnosed a specific problem and fixed it. Files from before my clean install start appearing on my desktop after my clean install when they were clearly deleted from a clean install. iTunes tends to go haywire and completely duplicate libraries or half libraries, and then scatter music all over the place as well. Files are duplicating themselves, deleting themselves, etc. ![]() I'm assuming it would be somewhere in the logs? However, I NOT getting any kernel panics. As for I/O Errors, I am not sure, as I don't know how to check for that. Disk Utility and disk warrior (both legal versions, none of this downloaded stuff), both tell me that my hard drive is okay. I've logged over 127 clean installs and have found the problem (as well as many other added quirks and erratic behaviors including a reappearing/dissapearing wifi card that sometimes is recognized yet fully functional according to hardware test) to reappear every time. However, I don't see why this problem would arise so randomly. After some reading, it seems as though "TRIM" settings on certain hard drives by different manufacturers can cause symptoms similar to this. As in the case for me, (after countless days and nights utilizing the process of elimination) I am fairly convinced that my 3 potentially infected macs (and router at this point) have either traveling root kits, some very very odd incompatibility with El Capitan and Trim on an older hard drive + externals, or just some other insanely unique hardware problem in my 27" 2009 iMac, as well as my 2010 MBPro. But chances are, they are out there, and you could even have one without having a clue. So obviously, there aren't going to be "Known" infections of rootkits. This makes "Known" infections, a myth, as discovering a rootkit without being an engineer is a fools errand. Rootkits are essentially impossible for even your above average techies to find. The reality about rootkits (especially firmware rootlets) is that they are virtually impossible to detect unless you are a highly trained professional or data forensics specialist. However, this has been going on for months upon months. A zero day and rootkits are NOT known in the wild yet. ![]() If so, which Firmware Restoration CD version do I download? None of the CD versions on the Apple website (1.3 to 2.0) list this particular Macbook.You are very right. ![]() Is there a way to force the Macbook to flash the firmware again, in the event this firmware is somehow corrupt? The RAM is known to be good RAM (pulled from another 2008 Macbook on my workbench) and is the correct speed for this Macbook (1066MHz, PC3-8500, Apple Branded RAM). I've checked the machine overview, and the Macbook is reporting the correct EFI Boot ROM and SMC versions for this model (Macbook5,1). A restart or shutdown will take us back to square one again. The SIL stays on, then about 25 seconds later, I hear the chime and the Macbook boots up normally.Įverything works: WiFi works, fan is running, all RAM is recognized, etc. At startup, it behaves as if it's performing a firmware update: Press power button, SIL comes on, blinks rapidly about 10 times, then I get one long beep (about 2 seconds). I've got a 13" 2008 Unibody Macbook, 2.4GHz. Hope someone like Mayer :) has an answer for this one.
