MacBook Pro Touch Id no longer working

Something a little different: a few days ago, after updating my Mac to macOS 10.12.6 and Windows 10 in the Bootcamp partition to the latest updates, the Touch Id button was no longer working. Symptoms:

unusual long boot time

Touch Id not recognizing fingerprint and no error displayed

unable to add a new fingerprint with the error "Unable to setup Touch Id".

I called Apple Support that suggested to boot in recovery mode and check the disk, to no avail. After a log of Google-ing, I stumbled upon this article about problems with Mac imaging. I checked the boot log as suggested:   

log show --debug --predicate 'process =="EmbeddedOSInstallService"'

And found the following error:

UserInfo= {NSLocalizedDescription=An error occurred installing the personalized bundle into the EFI system partition., NSUnderlyingError=0x7faa308747d0 {Error Domain=NSCocoaErrorDomain Code=513 "“EMBEDDEDOS” couldn’t be removed because you don’t have permission to access it." I mounted the EFI partition:

diskutil mount disk0s1

and checked the path /Volumes/EFI/EFI/APPLE/EMBEDDEDOS It was empty. I tryed reinstalling macOS from the Recovery Mode, to no avail. After too many reboots and to many Google searches, I re-read the log and found that the boot process was trying to copy the content of this folder

/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/1B46C9BA-0B38-4CEE-A809-812CB01224C8-EmbeddedOSInstallESPSandbox

to the EFI partition. I did it manually: no pain no gain. It worked! The boot process is now as fast as before and the Touch Id key is working again. Hope this helps. via Blogger http://ift.tt/2uaaGzi

Benchmarking TensorFlow Lite for microcontrollers on Linux SBCs

In this post, I’ll show you the results of benchmarking the TensorFlow Lite for microcontrollers (tflite-micro) API not on various MCUs this time, but on various Linux SBCs (Single-Board Computers). For this purpose I’ve used a code which I’ve originally written to test and compare the tflite-micro API which is written in C++ and the tflite python API.

Look ma, I created a home IoT setup with AWS, Raspberry Pi, Telegram and RuuviTags

Hobby projects are a fun way to try and learn new things. This time, I decided to build a simple IoT setup for home, to collect and visualise information like temperature, humidity and pressure. While learning by doing was definitely one of the reasons I decided to embark the project, I for example wanted to control the radiators located in the attic: Not necessarily by switching power on/off, but getting alarms if I'm heating it too much or little, so that I can tune the power manually.

How AI Accelerators Are Changing The Face Of Edge Computing

AI has become the key driver for the adoption of edge computing. Originally, the edge computing layer was meant to deliver local compute, storage, and processing capabilities to IoT deployments. Sensitive data that cannot be sent to the cloud for processing and analysis is handled by the edge. It...

Backdoors are a security vulnerability

Last month, US Attorney General William Barr resurrected a government appeal to technology companies: Provide law enforcement with an infallible, "secure" method to access, unscramble, and read encrypted data stored on devices and sent across secure messaging services. Barr asked, in more accurate, yet unspoken terms, for technology companies to develop encryption backdoors to their own services and products.

These startups aim to smash Apple and Google's smartphone duopoly

For years, the devices and services we use have ever more aggressively monitored our activities and mined our data. But as consumers have grown increasingly attuned to privacy concerns, solutions have been appearing to help them evade tracking. Browsers such as Brave and search engines such as...

7 steps to enhance IoT security

One of the biggest concerns with the Internet of Things (IoT) is making sure networks, data, and devices are secure. IoT-related security incidents have already occurred, and the worries among IT, security and networking managers that similar events will take place are justified. "In all but the most restrictive environments, you're going to have IoT devices in your midst," says Jason Taule, vice president of standards and CISO at security standards and assurance company HITRUST.

Creating a Blockchain from Scratch

Blockchains are becoming increasingly popular in today’s markets. Services that provide blockchain technology are already being designed by Amazon, Microsoft, Google and other huge companies. Many people often correlate blockchain with cryptocurrencies like Bitcoin, but many times, that isn’t the case. Right now, you might be asking yourself why blockchain is getting this much attention. What’s the big deal? So here is the deal — Blockchains allow us to create secure, public, and decentralized ‘databases’ to store any type of information. Before blockchain, large amounts of data had to be stored and verified by some form of middleman or intermediary. In this article, we will analyze the key concepts behind blockchain technology. Together, we'll go through the inner workings of a blockchain, and discover how information can be stored publicly over a distributed network of servers. This will all be done by constructing a simple blockchain from scratch.
