Can somneone explain me this?

On #MacOS's Save File dialog, if a file with a `:` already exists, the colon is replaced by `/` in the file listing.

And if I want to write a filename with a `: `, the text input changes it to `-`!

I've been experimenting with #Linux VMs on #macOS using #UTM. Two #Debian VMs, both on Apple's hypervisor, one with QEMU, the other with Apple's #Virtualization backend. Both are running Apache with PHP stack, boot with less than 200MB RAM in use, running Debian's cloud kernel.

The VM with QEMU boots in about 4 seconds, the full Apple stack VM boots in about 2 seconds. A full blown Linux environment with a container-like startup time.

Huh. I knew that Postscript support had been (foolishly) removed from macOS' Preview.app, but apparently at some point after that the pstopdf converter was removed as well. I used to use this to read manpages in a nicer format than a Terminal window.

Oddly, man -t ps (i.e., output Postscript) still works fine; there's just no built-in way to open the result.

Copying Remote Command Output to Your macOS Clipboard

A small trick to copy command output from a remote ssh session directly into the local macOS clipboard, using OSC 52 and a tiny shell script.

How fast is a macOS VM, and how small could it be?

To assess how small a macOS VM could be, I ran the same VM of macOS 26.4.1 on progressively smaller CPU core and memory allocations, using my virtualiser Viable. The VM’s display window was set to a standard 1600 x 1000, and I ran Safari through its paces and performed some lightweight everyday tasks, including Storage analysis in Setting

I'm considering bumping the macOS requirements for my binary package repository available at https://pkgsrc.smartos.org/install-on-macos/ again.

There's already a bunch of packages missing because they have newer C++ requirements than Xcode 15.4 supports.

What OS are folks running?

Why do Macs ask you to press random keys when connecting a new keyboard?

You might have seen this, one of the strangest and most primitive experiences in macOS, where you’re asked to press keys next to left Shift and right Shift, whatever they might be.

Perhaps I can explain.

It seems pretty obvious to me that's what it was for, but I guess man

Here are some things that one can add to the analysis of the MacOS TCP timeout clock freeze bug.

The code for calculate_tcp_clock() in XNU was changed in May 2025. Older versions of this function (e.g. in xnu-11417) worked quite differently and wouldn't have stopped ticking the clock at 32-bit unsigned integer wraparound.

None of #NetBSD, #FreeBSD, nor #OpenBSD share this exact way of doing TCP timeout processing with #XNU.

FreeBSD does not have a tcp_now and works off the global 32-bit ticks variable. OpenBSD effectively works off the kernel's system clock, too, but with a randomized offset, and does 64-bit unsigned modular arithmetic. NetBSD uses a distinct 32-bit unsigned tcp_now counter that it simply increments by 1 at regular intervals, and does modular arithmetic subtraction.

Mac OS X 10.0 Cheetah ported to Nintendo Wii

Since its launch in 2007, the Wii has seen several operating systems ported to it: Linux, NetBSD, and most-recently, Windows NT. Today, Mac OS X joins that list.

In this post, I’ll share how I ported the first version of Mac OS X, 10.0 Cheetah, to the Nintendo Wii. If you’re not an operating systems expert or low-level engineer, you’re in good co

Yay NannyTerminal on macOS!

If you paste “dangerous commands” now #macOS 26.4 prompts you saying “this could be dangerous”…

I do effing security, not “sekurity” or “theatrical representations of sekurity”, of course I paste “dangerous commands” like a ten line awk script to parse data…

I was waiting for a quiet moment to switch to Ghostty and… I’ll do it in the middle of a double IR storm ‘cos I effing need to paste whatever I want in my Terminal window, and fast.

Has anyone made a self contained Time Machine backup server (that runs on FreeBSD)? It looks like the old ways of backing up over the network finally broke, and I can't fool MacOS anymore by using a sparse disk image like I have for years.

I don't want to have to configure and install samba, I just want something that works and is small and self contained.

1. You have a Mac laptop with an outboard Bluetooth keyboard. It’s asleep.
2. You wake up the Mac by hitting the Touch ID on the laptop keyboard.
3. The Mac is annoyingly slow at starting to respond to keystrokes on the outboard. Several seconds, sometimes.

How to fix:

1. Hit any key on the BT keyboard. The Mac will start waking up.
2. Now hit the TouchID to get signed in.
3. Hey presto, the Mac is already listening to the BT.

Thank you for coming to my TED talk.

Hi all.

Just putting the feelers out as I'd love to know how many folks are using got on MacOs.

@teajaygrey does an amazing job every time I make a release of gameoftrees portable, but I could do with knowing how many of you are using it.

I made a change in the 0.123 release to fix socket handling for services such as gotwebd, which is good, but it's telling that it's taken this long, so I wonder how many users we have.

Let me know -- you can always email me at: thomas.adam22@gmail.com

Please boost this as much as possible, I'd appreciate it.
