PC + WSL + somewhat illicit OS X VM has been a dream for me as a former Mac user.

My mother asked me to help her out with her win 10 installation on her work notebook. This was terrible. UI is still inconsistent between apps, sometimes it feels like you are using 3 different OS from 3 different time periods. But you can get used to that I guess. OS settings are still a strange place created to make an average user (or someone who haven't been using the OS for more than a decade) feel as an idiot.…

Interesting it’s possible that we have different priorities, but I’m not bothered by UI inconsistencies. I use chrome, office, adobe suite, a trading application, games, VSCode, they all have different interfaces that I know how to navigate. I agree that the settings can be tough. Half the time you are in “new” stuff and half the time you’re pulling up the screens from XP. I just google what I need to do though, and never have trouble getting it done.

> IIRC there was no dedicated macOS “task force” like the one on iOS It's not surprising. Macs are less than 10% of Apple's revenue. https://www.macrumors.com/2020/04/30/apple-2q-2020-earnings/

But at Apple scale: 9% of $58 billion = $5.2 billion Mac revenue last quarter .

OTOH when Apple was a much smaller company the mac was much more important to them and it showed.

Maybe it's not related to revenue per se, but clearly since iOS became their main thing the Mac has suffered tremendously.

All of these complaints are about security features. Yes these features could be better implemented, but I'm happy they're there. It's very important to be able to opt out of them, but I like that they're the default. Notarization needs a cleanup pass and the rest of it seems like it needs an optimization pass. P.S. The rationale for notarization is to not distribute and thus advertise the filters and detection mecha…

Being able to run arbitrary software on the hardware Apple has graciously lent me is an annoying level of power that I'm not fully comfortable with either. I'm liable to shoot my foot off if Apple the all-seeing doesn't save me from myself.

I'm showing 20-200ms longer on first run of the exec. Modified the test script a bit to show that it doesn't happen again if you modify the executable's contents. echo $'#!/bin/sh\necho Hello' > /tmp/test.sh && \ chmod a+x /tmp/test.sh && \ time /tmp/test.sh && \ time /tmp/test.sh && \ echo 'echo Hello2' >> /tmp/test.sh && \ time /tmp/test.sh

Another slight modification to make this show the effect every time:

    f=$(mktemp) && \
    echo $'#!/bin/sh\necho Hello' > $f && \
    chmod a+x $f && \
    time $f && \
    time $f && \
    echo 'echo Hello2' >> $f && \
    time $f
On my system:

    Hello

    real 0m0.131s
    user 0m0.001s
    sys 0m0.002s
    Hello

    real 0m0.004s
    user 0m0.001s
    sys 0m0.002s
    Hello
    Hello2

    real 0m0.004s
    user 0m0.001s
    sys 0m0.002s

I would give anything to have my Mac be fast again. I have no idea what changed but even 10.14 feels a whole lot slower than it was earlier. Haven't upgraded to 10.15 seeing all the negative reviews it is getting when it comes to perf. Apple needs to seriously give perf a priority for Mac. Do they really expect developers to use a Mac to develop Apps when it is slow as molasses? I shudder to think what will happen to the Apple ecosystem if developers migrate to another OS for development. Apple will come crashing down. I don't wish for that to happen but looks like there is absolutely no one at Apple focused on making it better.

I can't upgrade IntelliJ any more, because it's trying to write to privileged file locations that I (the owner of the computer) no longer have access to. Believe me, I've tried to work around this, macOS has it locked down completely.

Why do you need access to the areas protected by SIP?

Beats me - it's a common problem, though: https://stackoverflow.com/questions/40251201/upgrading-intel.... The only thing that ever worked was uninstalling and reinstalling the whole thing.

“ Another way to reduce the delays is by disabling System Integrity Protection. I say reduce, because I still do get some delays even with SIP disabled, but the system does overall feel much faster, and I would strongly recommend anyone who thinks their system is sluggish to do the same.”

Nope.

Up until the release of Catalina, I've always upgraded to the latest version of macOS within a month or two. But some of the changes this time is really stopping me from upgrading.

As of Catalina, there's no sane way to install the Nix package manager without losing functionality because macOS now disallows creating new files in the root directory[1]. Nix stores its packages in the /nix directory and it's not possible to migrate without causing major disruptions for existing NixOS and other Linux users. This is too bad, since apart from Nix being a nice package manager, it also provides a sane binary package for Emacs. The Homebrew core/cask versions only provides a limited feature set[2][3].

I am using Ubuntu 20.04 on a Thinkpad X1 Extreme Gen2 and you would be surprised how "normal" it feels as a development machine. Sure there some little annoyances, the touchpad behaves a little worse than on windows, sound is a little worse. But the most important things, Keyboard and Screen are excellent. The system in general does not feel like the horror stories that people keep telling about linux on desktop(note…

The dual GPU is a pain in the butt since Nvidia still doesn't support Optimus on Linux (and probably never will).

Have you tried 19.10 or 20.04? Before that I had a lot of issues with my Dell XPS 9560 because of optimus, but it got a lot better in those versions. YMMV but it actually worked out of the box with nary a hint of manual configuration when I installed 20.04 recently.

Edit: should note, when I say work I mean you can switch between GPUs/launch an app on the dedicated GPU with ease.

The only time I’ve seen similar delays is when my mac decides it needs to do something on an external disk that needs to spin up. I have a 12Tb external that can take 10 seconds to spin up, so get a 10 second stall waiting for I/O once in a while.

I do wonder if the author has something similar going on, either with a directly attached disk or a network share.
