It's not possible.
From OSXDaily Where’s the Startup Boot Sound on New iMac & MacBook Pro?
One theory promoted online and originating from some web forums was
that you could re-enable the Mac startup chime sound effect by turning
to the command line. The claim was that by launching Terminal app and
entering the following command syntax:
I have a similar problem with my iMac 2017 and a 128 GB SD card (SanDisk Extreme Pro SDXC UHS-1).
My iMac (OS 10.14.6) refuse to mount the 128 GB card.
It's a brand new card and I use it in my digital camera. The card works as it should in my camera and I'm also able to ...
I suggest you do some testing before assuming it's the wifi connection. As a test, cable connect your computer to your router. Run speedof.me to check your performance with the cable connected and with wifi.
check how you are connected to your router.
If needed, change the order:
The airport card is usually pretty stable. You may want to start with the wireless router / air port. You can pick one up at your local store and return it if it does not fix the problem. As for the card itself it's replaceable but not really upgradeable from a quick google search. If you have a free USB port you can use a Wireless AC USB adaptor like ...
You can set NVRAM options from command line to boot into recovery:
sudo nvram "recovery-boot-mode=unused"
This will put your system into recovery mode.
NVRAM (nonvolatile random-access memory) is a small amount of memory that holds certain settings and can be accessed at boot by the Mac's firmware.
Re-installing as suggested above will fix the problem - temporarily! The next day you will end up in exactly the same situation, unless you stop all automatic updates from taking place.
The cause of the problem is a BUG in the 2019-004 10.13.6 High Sierra update, affecting my Mac Mini Server mid-2011, and obviously more mid-2011 machines.
I have forwarded ...
I don’t know if it’ll work with the Mini DisplayPort. I was stuck in a nasty half boot to grey screen problem last November on my 2011 27” iMac. While I was troubleshooting I tried the mini display port and tried TDM but it didn’t work. So I bought a Thunderbolt cable and then a FireWire cable or vice versa. The Thunderbolt cable worked... but I think the ...
@Tetsujin earns the garland.
The iMac's Safari had uBlock Origin 1.16.0 installed. When deactivated in Safari > Preferences > Extensions, Safari now loads the two problematic webpages correctly.
I'll guess that one of uBlock's data streams (it was subscribed to several, in aid of my trying to block persistent cookie-approval popups) was changed sometime ...
I would recommend OmniDiskSweeper or DaisyDisk as native Mac tools that can sort the entire volume by size, showing you what's using the space (and even delete it from within the app).
Apart from large application support files like sample libraries for Garageband, Logic, etc; then content in the User domain is likely to be the only thing that you can ...
chmod has an -R option to apply changes recursively to a whole directory tree but I strongly recommend to not use it for your scenario as you can break quite a lot of things by applying it in places where you shouldn't.
Log into your Mac as an administrative user and rerun JDisk. Not sure it will solve all your issues though as the tool seems to be ...
If anyone is wondering the answer to this… The actual panels are identical, but the connectors on the back of them are different. Also the display mounts on the actual display are different as well. So in conclusion, without some insane modifications, this cannot be done.
The Fusion Drive is significantly slower than the SSD on a MacBook Air. There is a portion of SSD on the Fusion Drive, but after copying all of your files over from your old Mac, it will take the operating system quite a while to determine which are the files/programs you use the most in order to "optimize" (i.e. put on the SSD portion of the Fusion Drive).
Actually that is, in most cases just fine.
I've been restoring my user profile on an older Mac to a newer Mac since the Migration Assistant was available on OSX. And I always do what you just did, restore everything.
That said, if you were having issues with your networking on the old Mac then it might carry over to the new Mac. But I have never seen ...
Yes RAM will help both with multitasking and having more is even more important with a fusion drive (from what I understand). If you want an even faster experience you might want to consider buying an external SSD and running most of your workload from that (and having internal fusion drive for archive and backups).
I'm a big believer in having more RAM generally, but of course in many situations having more RAM isn't warranted. In your case, however, having more RAM is going to be useful because of the type of tasks you're using your iMac for.
The key spec missing from your question, however, is the type of storage you have. If your iMac has one of the Fusion drives, ...
You could use a USB video capture device to capture the video output from your Wii or Wii U.
A device like this with support for macOS will show up in QuickTime, which you can switch into Full Screen, and could allow you to use your 27" iMac as a display.
Try sudo sysctl -w net.smb.fs.loglevel=255 and see what messages you get in the console window.

I just tried connecting a macOS 10.14.5 to RealVNC 6.4.1 on a Raspbian Buster.
To make it work, I had to disable encryption and configure VNC password instead of (Interactive) UNIX password authentication.
There is no clipboard or observation mode support and I wouldn't use it through a WAN because of the lack of encryption, but it works.
Nimesh Neema is correct, you cannot use your iMac in Target Display Mode as this feature has not been supported in iMacs manufactured for about the past five years.
However, there are some software options you can investigate, but I have no personal experience with them. Two of these options are listed below:
In summary, they ...
As Tetsujin accurately states, you cannot use your MacBook Pro in Target Display Mode nor achieve the same result via a ThunderBolt 3 (USB-C?) to ThunderBolt 2 cable.
However, there are other options you can investigate, but I have no personal experience with them. Two of these options are listed below:
In summary, they promise to ...
If you mean Target Display Mode, then no - that was a feature only available to a select few iMac models & now defunct.
See Apple KB - Use your iMac as a display with Target Display Mode for details.
It was essentially available on iMacs between 2009 & 2014.
