Fixing the macOS 10.13.6 Security Update 2019-007 Black Screen

My iMac 27-inch (mid-2011) is still working well. For some unknown reason(s), I’ve been unable to apply the macOS 10.13.6 (High Sierra) Security Update 2019-007. It will simply “halt” during the reboot phase, leaving me with a black screen with cursor. The most irritating part is that I cannot uninstall nor (re)install the Security Update and it continues to halt my iMac at the black screen at every shutdown or reboot. I had to force shutdown by holding on the power button every single time until I came across a fix for failed Security Updates on Apple’s forum.

Baseus GaN 65W Mini Quick Charge Travel Charger Review

USB-C is pretty much the de factor connector standard for charging mobile and computing devices these days. Quick charging protocols such as PD 3.0, QC 4+, QC 3.0, SCP, FCP, AFC, PE+, etc. are pretty much the norm. To concurrently charge multiple devices, I searched for a portable charger with at least two ports. That is when I found the Baseus GaN (Gallium nitride) 65W Mini Quick Charge Travel Charger at S$37.61.

In a Zero Trust Architecture, it eliminates the inherent trust bestowed on internal networks. Instead all access to resources are inspected and granted on a least-privileged strategy regardless of location. Sounds cool? Read on.

N2 Elite NFC Emulator

Nintendo Switch owners should be familiar with amiibo figures. By tapping them on the right Joy-Con controller, you can unlock in game bonuses and add a lot of fun to compatible games. These bonuses are not single use and people actually share them with family and friends. To do so, they either borrow the amiibo figure or clone their data onto compatible NFC tag. I got the N2 Elite NFC Emulator to do just that.

Ring Video Doorbell 2 Review – Upgrading your old doorbell to a smarter one

Considering that how infrequently I change flat batteries in my doorbell, I did not even once think that I will ever get a smart video doorbell. So why did I get it? Because of a weird encounter that my neighbour had – a agitated guy pestering/ questioning for someone on a late night. I don’t think such encounters are great. Without much hesitation, I picked up the Ring Video Doorbell 2 during the Amazon Prime Day sales.

Comply SmartCore Foam Tips with Sony WF-1000XM3

I bought the Sony WF-1000XM3 Truely Wireless Earphones last month and have almost been using it daily during commute. The Sony WF-1000XM3 is great but I find the included tips (both silicone and foam) lack-lustre in areas of fitting and isolation. As Comply does not have a specific recommended foam tip model for the Sony WF-1000XM3, I decided to try my luck with their SmartCore series. I am glad to say that the Sony WF-1000XM3 and Comply SmartCore series are compatible. I got 3-pack off Lazada for S$24.00.
