How to Set an 80% Battery Charge Limit on MacBook without Third-Party App

For the longest time, I relied on a third-party app called AlDente just to do one simple thing: Stop my MacBook from charging to 100%.

If you’ve read my previous how to manually set battery charge limit post, you know I used tools like AlDente for this. It worked great, but honestly, I always wished Apple would just build this feature directly into macOS.

How to Start macOS Recovery and Connect to the Internet Without Wi-Fi

Previously, I wrote about how to restore the missing Wi-Fi icon in macOS Recovery. That solution works just fine for most Mac users.

But recently, in March 2026, Apple released the new MacBook Air M5 and MacBook Pro M5. They look like great machines, but I’ve received a lot of reports from people who are unable to activate their M5 Macs.

You see, some people use Migration Assistant to set up their new MacBook M5. They want to transfer data from their old Mac to the new one. From what I gathered, everything goes smoothly until they reach the Activation screen in macOS Recovery.

Fix Missing Wi-Fi in Recovery Assistant After Resetting Your Mac

So you want to reset your Mac to factory default. Maybe you want to sell it. Or maybe you just want a fresh start. Whatever it is, you know what you’re doing.

UPDATE 2026/03: If you’re an owner of MacBook Air M5 or MacBook Pro M5 that’s shipped in March 2026, this method won’t work. There is a known bug in macOS Recovery shipped in those Macs that cause missing Wi-Fi icon during Activation. You can still activate your M5 Mac using wired internet access.

Install Mendeley Desktop for Mac with Homebrew

Recently I noticed that the official Homebrew Cask removed the Mendeley Desktop app for Mac from their repository.

That makes sense because this app hasn’t been updated for a very long time and has actually been replaced by the new Mendeley Reference Manager app.

But maybe you’re currently writing a paper and still want to use the Mendeley Desktop app until your paper is accepted or you graduate. If that’s the case, you can still install it using the Homebrew package manager through a Homebrew Tap that I manage.

How to Take a macOS Window Screenshot Without the Shadow Background

author@junian.dev (Junian Triajianto) — Thu, 26 Feb 2026 04:00:00 +0700

I take a lot of macOS app screenshots for my blog.

The default screenshots look beautiful — whether it’s the entire screen, a selected portion, or a selected window.

One special thing when you capture a macOS window is that it automatically adds a soft shadow around it. It looks good. It looks polished.

Most of the time, I don’t need to remove it.

But in some cases, that shadow really takes up extra space. So I started wondering: is there a way to take a macOS window screenshot without the shadow?

How to Take Screenshot on Mac with Keyboard Shortcuts

I take a lot of screenshots for my blog, and doing that regularly without remembering the shortcuts is a mistake.

There are basically three different ways to take a screenshot on macOS.

Each one has its own shortcut.

So here are all the shortcuts you need to remember to take screenshots on macOS.

Screenshot App Shortcut

⌘ command + shift + 5

If you don’t want to remember all the individual shortcuts, just remember this one.
