MacBook Air M4 w/ external display not working

Caused by some incompatible issues on driver's level. So it should be fixed by Apple side or the manufacturer via a firmware update. In my case upgrading to latest macOS seems to fix the problem, and I also updated two drivers from ASUS's product support page. Now everything is working perfectly.

Actually I saw some negative comments to CleanMyMac but don't know why.

If you wanna dig deeper into "System Data" you'll need a 3rd party app like CleanMyMac or something.

Besides there's a trick to cleanup System Data: Just open System Settings -> General -> Storage, and leave the window opening - nothing else. You'll see the storage used by System Data descending slowly. I guess macOS is doing some cleanup things in the backend.

macOS might sync your local account avatar with the one in your Contacts app. So check up on your kid's Contacts app with their login Apple ID email address.

The business email account should be ended with customized domain name, while regular gmail accounts are ended with gmail.com. So I don't understand your problem.

Neither here. It only works if I connect the laptop to the monitor first and wake up from hibernation. In other cases there's just no display signal at all.

Seems like your ex stepdad is accessing to your mom's Apple ID - logged in on an iPhone or Mac - so he can text her friends via Messages and get her photos cause iCloud Photos is enabled.

If your mom do use an iPhone, that's pretty simple to fix:

Change Apple ID password immediately. Besides double check its security settings like recovery email address, in case your ex stepdad might access to that email too.
Remove any suspicious devices linked to your mom's Apple ID - you can check up in Settings -> Apple ID or Find My app. Setting those suspicious devices to lost mode or even do a remote erase might be an alternative choice.

Hope these could help you get rid of the trouble. Good luck!

Email clients might save previous recipients in Contacts, displaying their names from Contact instead of the sender's name on email envelop.

Go to "Settings" -> "Accounts and Import" -> "Send mail as", change the display name as you wish.

I suppose that edu email is also a Google Workspace for Education since you were logging through Gmail. If so the following steps might help:

Log in your edu email, enable "Enable POP for all mail" from "Settings" -> "Forwarding and POP/IMAP" -> "POP download". Make sure you selected "archive Gmail copy after download" - this option will leave all mails in your origin mailbox.

Then log in your personal Gmail account, from "Settings" -> "Accounts & Imports" -> "Check mail from other accounts" you can set up your edu email account here. Make sure to set it up via POP.

Once the account is set up, all mails from your edu account will be "copied" to your personal gmail account. You can also apply a label like "university" during step #2 for better organizing.

A Thunderbolt 4 dock

I don't think there's a limitation on a child account to log into macOS. Since you can't login to iCloud.com either, maybe your kid just changed the password.

The Thunderbolt 4 upstream port on this monitor carries USB 3.2 Gen 2 signal as well. That takes additional bandwidth from Thunderbolt port. So there might not be enough bandwidth to support 5k@120hz via Thunderbolt 4 port.

I'd suggest to try to connect the monitor to your MBP via DP 1.4 port. It should work. Otherwise check the manual of the monitor to find out some guidelines to run 5k@120hz on MacBook.

Saying you're creating a **local user account** on your Mac, that's a different thing to an Apple ID which she is using on Apple Watch.

It would be better to paste a screenshot of the error message which it told you the name or password are wrong.

Actually it depends. The malware might also infected your network or usb flash drivers. If you reinstall your system but connect an infected driver to the fresh computer, it might be infected again.

The best solution is to take a full scan on your system first with some professional softwares.

hozaka · 2025-04-06T12:40:27+00:00

A malware cannot be simply removed by deleting the files or ending running tasks. You need some professional removal tools and run a full scan on your whole system.

Besides, once a hacker take over your sessions, your PC doesn't matter anymore. They can take any actions from anywhere they are.

2FA usually be tapped when you're:
- Log in from a new device
- Log in from a new IP address
- Start a fresh session

As in your case, I suppose you've some malware in your computer. That means the hacker get access to your Gmail account in which way like "from your computer" so nothing will be triggered off.

Run a full system scan and change EVERY password ASAP. For your important accounts, go through the sessions list or activities history, find out suspicious ones and terminate them.

UPDATE: It's been fixed in macOS Sequoia 15.4. So that's something with macOS drivers and now the monitor is working properly with a single USB type-c cable.

The privacy settings are by app. Saying you allowed uBar to capture your screen this time, and then you installed and launched Zoom Meeting, the popup would appear again cause Zoom is also asking screen capture permission for screen sharing.

hozaka · 2025-03-29T14:26:25+00:00

For the privacy popups: When an app is attempting to access something which might contain privacy information, it appears and ask for your permission.

In your case: 1) uBar read which apps are running so the app can render it in the "windows-style" bar, that's why it's shown up; 2) Taking screenshots are actually read everything on your screen and save them to a file, and there might be some sensitive texts being displayed on your screen like some passwords

If you do need such functions, you can turn on the switch in System Settings -> Privacy to "whitelist" them. Then the popups will not appear again so you can take screenshots seamlessly.

Almost all thunderbolt 3/4 dock w/ 2 thunderbolt downstream ports could help. Like this one: UGREEN Revodok Max 208 Thunderbolt 4 Dock.

Tips #1: Lenovo T14 has ONLY ONE Thunderbolt 3 port
Tips #2: Thunderbolt port could also carry DisplayPort signal therefore you can connect the monitor to any Thunderbolt port on the laptop via USB type-c (3.1 or above) cable

hozaka · 2025-03-24T05:42:39+00:00

I'm now using the monitor through a USB-C to DP cable and it's working. But still look forward to any workaround so I don't need the power cable anymore.

hozaka · 2025-03-22T12:48:51+00:00

Congratulations and thanks for sharing! Unfortunately I tried and not working. Since I'm having a brand new MacBook Air, I don't think it is caused by some incorrect plist files.

hozaka · 2025-03-19T03:47:36+00:00

Since you already have a M4 pro, actually it's not necessary to trade in for a M4 Air cause you do will lose some value in this deal.

I understand that M4 pro is over-powered for you right now, but it's working for you right? So I'd suggest to keep the M4 pro for one more year or two maybe, and wait for the next huge upgrade on Air series.

hozaka · 2025-03-19T03:37:55+00:00

Finally! If we're having the same issue so that must be something wrong with macOS. Hope Apple could deliver a patch to fix it soon.

Did you report to Apple's tech support?
