Over the past few weeks, I've tried everything to move my Time Machine backup to a new disc. I documented what worked (and what didn't). www.seandeaton.com/migrating-ti... #Mac #macOS #apple

Migrating Time Machine Backup to a New Disc
Moving a macOS Time Machine backup to a new disc is a headache. Here's how to do it.

Just set up the @pimoroni.com NVMe base for my #homelab. I'm grateful for their super easy setup and clear instructions! Boot time down to 10s from 15s. Not huge, but I'm glad to have something more reliable than a microSD card.

How well does Binary Ninja's decompiler utilize Apple Silicon P-cores? Pretty well. If you're a reverse engineer looking for a new machine, opt for more cores. Seems obvious, but I had to test. 😊 #binaryninja #ghidra #ida #macOS #decompiler #reverseengineering www.seandeaton.com/decompilers-...

Decompilers and Performance Cores
How well does Binary Ninja utilize Apple Silicon’s P-cores? More P-cores lead to faster decompilation—worth considering when choosing your next M-series chip.

It turns out that activating an iPhone 3G in 2025 isn't as easy as opening up Finder and restoring. I've written up a blog post to help anyone else in this predicament. 😃 #ios #iphone #iphone3g #macos #apple www.seandeaton.com/activating-a...

Activating an iPhone 3G in 2025
Turns out that activating older iPhones is no easy feat in 2025 or macOS Sequoia. Using iOS Legacy Kit solves this problem.

If you're not utilizing 150% of your available RAM, you're leaving money on the table. Or at least that's what I tell myself so I don't need to upgrade quite yet... #apple #macos

Binary diff'ing is hard. But it's super powerful to apply markup from previous reverse engineering efforts to a new binary. Binary Ninja is switching up how they match function signatures with WARP. www.seandeaton.com/binary-ninja... #binaryninja #reverseengineering #ghidra #ida #decompiler

Setting enums in Binary Ninja previously broke down when any enum member was set to zero. @binary.ninja 4.3.x now ignores any 0 value for enums, when used as bitfield masks, to aid readability. www.seandeaton.com/enums-just-g... #binaryninja #binja #ida #ghidra #reverseengineering #decompiler

Enums Just Got So Much Better in Binary Ninja
Enums in Binary Ninja have always been nice, but they are even better in the latest 4.3 update.

Highly recommend checking out @lukasarnld.bsky.social’s talk on the iOS baseband. It’s up on the OBTS YouTube livestream right now. Video out in a couple days?

So I benchmarked how much faster the newer Apple silicon chips were in decompiling programs with Binary Ninja. No surprise, the M2 Ultra performed well. Also, RAM is important. @binary.ninja #binaryninja #reverseengineering #mac

Comparing Binary Ninja Performance on the M1, M2 Ultra, and M3 Pro
We test the time to decompile programs in Binary Ninja over various Mac configurations. No surprise, but the M2 Ultra fared pretty well.

There are tons of YouTube videos comparing Apple’s M4 lineup against Adobe Lightroom, Photoshop, Final Cut Pro, etc. We need a channel or blog for reverse engineers that shows how much faster I can decompile the dyld shared cache with the M4 Max over the Pro. 🤔
