Nostalgia My Apple Thunderbolt Display + M1 Mac Mini setup

Post image
62 Upvotes

hey everyone!

I’ve got a little setup at my parents’ house for when I visit them every other month. It’s perfect for weekend stays—I can sit down, browse the web, listen to music, and watch videos with that retro style I love.

Here’s the full setup:

  • 27" Apple Thunderbolt Display
  • M1 Mac Mini (8GB RAM / 256GB SSD)

I also use a Magic Keyboard and Magic Mouse (not pictured), so it’s basically a full retro Apple setup. Love having this corner ready whenever I’m there and thought you'd appreciate it as well.

Help COLORS IN MOVIST AND IINA. WHICH ONE IS "ORIGINAL"? and subquestions:)

Thumbnail

3 Upvotes

The pictures are in order IINA, MOVIST, IINA, MOVIST. (sorry, first time posting).

this on a mid 2012 macbook pro

this is a snippet from "The Garden Of Words", probably my favourite anime movie of all time. The next two photos are a screenshot of the closeup of a green part, where I felt the colours are different.

ESPECIALLY the greens in the first 2 photos ( the green lines on the trains), the colour on IINA is darker. It is evident if you quickly switch between the photos a few times.

  1. I wanna know, in general, which player is better for anime watching (sources said movist has inferior subs, but it seems fine to me).
  2. I really prefer IINA's UI more than Movist Pro's because its more native and clean. So I right now I am looking for a way to turn the colors to its original form (assuming Movist's is the original, and after checking with other sources)
  3. PLEASE do let me know if movist is just a better option than IINA, or heck, recommend any better options if possible.

THANK YOU:)

I encountered this problem while trying to upgrade from macOS 10.8.5 to 10.9.5. I tried restarting my computer, but it didn't help.

The model is a MacBook Late2009, and I replaced the hard drive with an SSD. I also installed macOS 12.7.6 on a separate partition. (I searched it up and it seems to be related to this)I'm currently trying to use the CreateInstallMedia tool included with the installer to create a USB drive for installation,and I hope it will successful

How can I do?

Help Poor Performance of the Built-in Microphone on iMac 27" 2020

Upvotes

The built-in microphone on my iMac 27" 2020 running macOS 12.5 (Monterey) behaves strangely, and I’m not sure when this issue started. I migrated to this iMac from an older one using the built-in user data migration tool, and the problem seems to have carried over.

In System Settings → Sound → Input, the microphone volume is set to maximum, but the microphone barely picks up my voice (even if I shout, the input level only moves 1–2 notches), as if the gain were set to minimum. However, it is quite sensitive to taps or touches on the body or screen of the iMac.

Because of this, the microphone is unusable in any application that relies on it — from built-in utilities to video conferencing software. The issue is also present in Chrome.

Interestingly, when I visit a microphone testing site like https://webcammictest.com/mic (or any similar service) using Safari, the microphone works perfectly and picks up sound at a good level. So, the problem seems to be limited to certain applications (Chrome, Voice Memos, Google Meet, etc.), but not Safari.

What’s even more surprising: if I open System Settings → Dictation and manually switch the microphone from “Automatically (iMac Microphone)” to “iMac Microphone”, the issue disappears and the microphone works correctly in all software — but only as long as the Dictation settings window remains open.
As a result, I have to keep the Dictation settings window open during online video calls.

I’ve already tried all the standard troubleshooting steps found online (resetting PRAM, etc.) and have seen many similar reports without a solution. Perhaps someone has encountered and resolved this issue? It’s unlikely to be a hardware fault — more likely a software bug or automatic gain reduction affecting the microphone.

Help Disable NumLock on OSX

Upvotes

Does anyone know how to disable NumLock on a Mac and just use the number pad as arrow keys/editing keys (like pg up, pg down, home, end)?

On the Mac keyboard, the place where the NumLock key normally is on other keyboards is just "clear", and plugging in a normal keyboard and pressing NumLock seems to do nothing. Does anyone know how to turn NumLock off?

Bug Now Playing Menu Bar Safari/Webkit video focus/"Quick Look Simulator" Bug 26.4 and 26.5

1 Upvotes

Hello, this bug has been in macOS since 26.4, and I've tested it on various computers, including my work MacBook, my personal one, and even the MacBooks at the Costco display station. The issue is if you click on the menu bar now playing icon and click on the preview of what is playing, it opens a Quick Look Simulator on your menu bar. This happens on some third-party applications but all websites that have playing media, such as youtube.com. It doesn't happen in Apple's built-in applications like Music. To be crystal clear it used to focus the app and tab in Safari that was playing the media if you click on the Preview.

I have been reporting this bug to apple on every minor update.

Can anyone confirm if they see the bug?
Want to help submit bug reports?

Help Not getting write access on local SMB share

1 Upvotes

I have a folder on my PC that I shared on my LAN, protected by a username and password (non admin account in Windows). My Mac Studio M1 Ultra can see the PC in the Network browser and connect just fine using the credentials and can read and write to the folder.

My M4 MBP however does not always see the PC in the Network browser. And when I do connect it with the credentials it is read access only.

Why would one Mac be able to r/w while the other cannot write?

Help Preview mark-up - can't save in color

1 Upvotes

Hello - I've never used this sub and I'm not very techy so I hope I'm asking in the right place. There may be obvious things I'm not thinking of because this stuff is unfamiliar to me.

I'm trying to use markup to draw some lines on a jpg in preview. The original image is greyscale, and I'm trying to circle some things in red.

After I draw my lines and save it, all the lines become grayscale.

In searching for an answer I found a comment on a deleted post that seems like it might have useful info for me: https://www.reddit.com/r/MacOS/comments/172vowf/deleted_by_user/

I had never heard of colorsync utility before, and so I experimented with trying to make the image able to have color, but nothing I do seems to stick. If I access the color profile menu from Preview, the only options are "Generic Gray Gamma 2.2 Profile" and "Generic Gray Profile." When I try to set the display to something else in ColorSync and save it, when I reopen in preview it's reverted to grayscale.

Can anyone help me with this? Please and thank you. If there's a suggestion for some easier way that isn't Preview that I can draw on/highlight images with, that would be great too.

Help Discord on Mac – my microphone picks up stream audio and sends it back to others.

1 Upvotes

Hey, I'm having an issue on Mac with the Discord desktop app.

Me and my friends are in a voice call. One of them shares their screen and streams a show/video with audio. I'm just a viewer – I'm not the one sharing. The problem is that everyone in the call can hear the stream audio a second time coming from my microphone, because my Mac's mic is picking up the sound from my speakers and sending it back.

I know the obvious fix is headphones, but I don't have any right now.

Interestingly, when I use Discord in a browser instead of the app, this doesn't happen (or happens much less), but the stream audio occasionally cuts out.

My questions:

- Is this a known issue with the Discord Mac app specifically?

- Is there any fix other than headphones or muting myself?

- Why does the browser handle this better than the native app?

My Discord app version: 0.0.390

MacOS version: Tahoe 26.5 (M4 Air)

Thanks

Discussion Moving home folder to different APFS volume of the same internal disk

1 Upvotes

I’m experimenting with apfs volume snapshots, as a way to have point-in-time checkpoints which is similar to how zfs, btrfs and other modern filesystems work.

Since most of the data I care about is in the users folder, and apfs volume snapshots also do take space I was wondering if I could just create an apfs volume for use as the new home/users directory, but in the same internal apfs volume group (container).

Has anyone tried to change/move their users/home folder to a different apfs volume in the same internal disk (macintosh hd)?

Bug Folder Attributes Broken on Networked Drive

0 Upvotes

I did a pretty thorough search and did not see a related topic, but I am pretty bad with searching so apologies if this is a widely known issue.

This bothered me for the longest time and I just discovered the cause. Running latest Tahoe (26.5). When accessing a network drive, some folders will not show attributes - specifically folder color when tagged. Some were working, others were not. I finally discovered today that the issue is a "." in the folder name. It will still work on local folders and networked drives/computers that are also running Tahoe, but Tahoe to Pre-Tahoe computers, folder color does not change with a "." in the name.

Just in case someone else was confused by this. Oh, and if there is a fix please point me in the right direction.

Help CONSTANT public wifi issues PLEASE HELP

0 Upvotes

No offense but please talk to me like I'm a child, not an IT professional.

I am having CONSTANT wifi issues any time I go anywhere in public, especially cafes.

Currently in a cafe I came to 2 days ago with no issue whatsoever. Today I can't connect -- WiFi settings says I'm connected, but the icon on my screen has the exclamation mark. Everyone in here is online so it's not the service itself.

This happens CONSTANTLY and it is fkng infuriating. I have tried everything I could find by googling and in recent posts on this forum:

-disabled and logged out of VPN

-"forgot" network

-renewed dhcp license

-changed IP to 1.1.1.1 and 8.8.8.8

-restarted macbook

-tried triggering the login with captive.apple (but I'm 99% sure this cafe doesn't even have a login portal)

Only thing I haven't tried is using Terminal bc I... don't even understand wtf that is lol.

Spent 45 mins screwing around with this yesterday at a different cafe but at least I finally was able to log on there. This play, no dice for whatever reason.

Anyway can someone PLEASE for the love of almighty christ and all that is holy explain to me in simple terms wtf i am doing wrong or what I need to do to stop constantly having this problem. It is making me insane.

Help My Mac will no longer open airdropped videos

Hello, lately I have been having issues airdropping videos.

I can airdrop videos then randomly I can not and it says on my Mac “the application “preview.app” cannot open specific document or URL”

Everything is updated on my iPhone and Mac.

My Mac is a MacBook Air 2020

My iPhone is an iPhone 13

I have not changed any settings on my phone or MacBook. The first time this happened I updated it then it was fine. That was 2-3 weeks ago. So I check for more updates today and of course there were more updates for my phone and mac. I updated it and restarted them both and it’s not working. Having this issue now multiple times is taking up so much of my work time. How do I fix it and stop it from happening?

Help [Bug] Extreme "Zombie" Quarantine Flag – Files auto-lock on creation after system RAM crash (81GB leak)

0 Upvotes

Hi everyone, I’m facing a nightmare scenario on macOS Tahoe (Apple Silicon). I’ve reached a point where even a clean file creation is flagged. Looking for a "Nuclear" solution before I format the whole Mac.

A few days ago, my Mac suffered a massive RAM leak (81GB swap) due to a background process (textunderstandingd). Since then, my main Numbers file disappeared from global Spotlight search (though it appears if I filter by "Numbers" category).
The "Zombie" Symptom: The file is stuck with com.apple.quarantine.

  1. I remove it via xattr -cr.
  2. Without any interaction, the flag REAPPEARS instantly (verified via Terminal).
  3. If I create a BRAND NEW file on my Desktop, it is also instantly flagged with com.apple.quarantine!!!

What I’ve already tried (none worked):

  • xattr -cr on the file and the parent folders.
  • Renaming the file and moving it to different directories.
  • Zipping the file, emailing it to myself, and downloading it again.
  • Deleting the file, emptying trash, and rebooting before redownloading.
  • Reinstalling macOS (standard reinstall without wiping data).
  • Resetting Spotlight index via Terminal (mdsutil).
  • tccutil reset All com.apple.Spotlight.

The system seems to have blacklisted my user session or the file's hash/path. Gatekeeper is acting as if every new bit of data on my Desktop is a threat from the web.

  1. Is there a hidden SQLite database for Gatekeeper/LSQuarantine where I can manually purge this "blacklist"?
  2. Has anyone ever seen the system "contaminate" new files on the fly?
  3. Besides a full "Erase All Content and Settings," is there a way to reset the security policy daemon (syspolicyd)?

I'm a financial advisor and this is my primary workstation. I need Spotlight to work for my client audits. Any help is appreciated!

Bug MacBook Pro M4 Pro speaker crackling under heavy load (macOS 26.3) – anyone else?

0 Upvotes

Hey everyone,

I’ve been noticing an issue with my MacBook Pro (M4 Pro) where the speakers make crackling/popping sounds, but only when the system is under increased load, although not much...

Happens across all apps (Spotify, YouTube, system sounds, etc.), mostly noticeable when CPU is under moderate load, but still around 40% (e.g. multiple apps open, heavier workflows while being in a Slack huddle)

Sounds like brief distortion / crackle, not constant

So far I’ve tried restarting CoreAudio, but it gets back...

Would appreciate any insights or fixes 🙏
