Fixing faulty temperature sensor in the MacBook (aka Ts0P)

back in the summer of 2016 I was eating an orange while working just to end up with a drop of orange liquid inside the keyboard of my beloved macbook.

I am very attached to this macbook since years, and this juice decided to ruin the worst possible key [SHIFT] in the mac, hence all I was able to write is capital letters, the booting won’t work because it MAC OS boots to safe-mode by default if the shift key is pressed on booting time. Even worse than this all was not able to login into my environments because the all my passwords were capitalized.

Back then I decided to override the [SHIFT] key using a software interupt, which worked greatly until I decided to replace the whole macbook keyboard. The process of replacing the keyboard wasn’t that complicated, what came next was ūüôā

Hacking short distance devices

Intro:
Hacking is not only for computer, software, or websites. Any device can be hacked. I lately started having interests in Software Defined Radio where I was able to ‘sniff’ data of signals around me. One particularly interesting signal was the short distances devices. These include:

  • Car remotes system. Also called: Remote Keyless System
  • Garage Remotes
  • Other home equipment¬†remotes switches.

Some of these systems are known to have security flaws in them. Some have no security mechanisms. It is worth reading how these stuff work before going deeper into hacking them.

Requirements:

  • Programming skills in: C++ or Java or Python.
  • A micro-conotroller (Teensy, Aurdino) Raspberry Pi is ok too.
  • 315Mhz / 430Mhz Transceiver. I bough this one > XD-RD-5V.

Mixing different RAM Sizes in One Computer

Can you install different sizes of RAM into a single motherboard and it will still work? Yes you can!
There a tiny tricks you will need:

  1. Make sure you’re buying same speed/voltage/non-ECC sticks.
  2. When installing them install them in this way:   || Slot#1:[1GB+512Mb] || Slot#2:[1GB+512Mb] ||

I tried to install them in other order but all my tries have failed. The only thing that worked is installing them in the order I mentioned above.

~ Happy upgrading.

KINGSTON KTL-TP1066 8Gb for MacBook Pro mid 2010

This is to confirm that a¬†KINGSTON KTL-TP1066/4G x2 will work on a MacBook Pro¬†(MacBookPro7,1) –¬†mid 2010.

Although there is no sign on the internet that this will work on a Mac, I had to take the risk and test it myself (having to order one from US all the way to Qatar). It works like charm, and my Mac is super fast again running the latest version of OS X.

Here they upgrade a Ram for around 215$, I ordered the 8Gb sticks for 65$ only! You can also order other types of Rams online just make sure you have the same specifications as the one mentioned in your current installed Ram. Feel free to ask me about the model you have on the comment section.

Happy upgrading folks.
