IMac Target Display Mode – Request different

Have you tried all the steps recommended by Apple?

Use target view mode

Follow these steps to start using your iMac as a screen:

1 Make sure your iMac is turned on and the other Mac is connected to a macOS user account.
2 Connect the Mini DisplayPort or Thunderbolt cable between the two computers.
3 Press Command-F2 on the keyboard of the iMac you want to use as the screen.

After pressing Command-F2, your iMac displays the desktop from the connected Mac.

If Command-F2 does not work

If your iMac does not switch to target display mode when you press Command-F2, check the following:

• Make sure that the iMac you are trying to use as the display supports the target display mode.
• The target display mode only works when your main Mac is connected to a macOS user account. For example, if your first Mac is at the FileVault login screen, pressing Command-F2 on your iMac does not activate the target display mode. You must first connect to your Mac (with the help of a normal screen, if necessary) before you can use an iMac in target display mode.
• Make sure to press Command-F2 on the keyboard connected to the iMac you want to use as the screen.
• In Keyboard System Preferences, if the checkbox is enabled for "Use all F1, F2, etc., as standard function keys", the key combination becomes Command-Fn-F2.
• Make sure your Mini DisplayPort or Thunderbolt cable is connected to both computers.
• If you are currently connected to the iMac that you want to use as a display, try disconnecting to return to the login window. Then press Command-F2 again.
• Some older Apple keyboards and third-party keyboards may not allow Command-F2 to switch between display modes. If this happens, use the keyboard that came with your iMac to enable or disable the target display mode.
• If your iMac is currently booted on Windows, it will not go into target display mode. Target display mode is not supported in Boot Camp.

hardware – Black screen when using 4 RAM sticks on the brand new 5K iMac

I bought a 5K iKM 4 months ago, with the stock of 8GB of RAM. I bought 2 x 4 GB extra on Amazon (Crucial Ram). But then, it seems that I can not use the 4 RAM slots at the same time. The iMac does not even start, only displays a black screen.
The Crucial ram sticks work 100% because I tried to remove the original ram sticks, using only the new ones, and that the Mac starts and works properly.
Right now, I run the iMac with 3 of the 4 sticks, so at the moment I have 12 GB of RAM.
I've tried using the 3 best sites, it works. Down 3, it works.
2 slots works too.
But as soon as I insert a 4th ram stick, it stops working
I have reinstalled the SMC and NVRAM. Still no luck
Also updated Mojave at 10.14.2 (latest version)

Ideas?
I would like to see if I can try something before setting an appointment with Apple for this, as it is my main work machine and I have to work on some projects now.

Thank you so much!

lion – 2011 iMac 27 ": can not upgrade to the latest OSX after replacing the failed drive with a new blank hard disk Nasty loop

Installation of a new hard drive on a 27 "iMac 2011: the old drive could not boot (FSK unresolved node errors) .This failed drive was running High Sierra before stopping to boot .

Removal of the old drive and installation in an external powered box.

  1. New hard disk installed – but remote installation of OSX is limited to Lion (10.7), as Apple's remote recovery only reinstalls the original supplied OSX printer.

  2. I can not find any way to find the recovery partition on the old drive.

  3. I've tried to update OSX from the App Store but the shopping list of my account shows no OSX (many of my apps though)

  4. I can not check my Apple App Store account settings as "To edit your payment information, you must upgrade your Mac with the latest version of macOS." (That's what I'm trying to do!)

  5. I've tried to download El Capitan from the beautiful Apple page configured for this, but by clicking on "Get", it is stated that Paypal will send me a message to confirm the account, but that's not the case. was more than a day ago.

  6. We also discovered how to use the terminal (fsck_hfs -r / dev / disk1s2) to try to rebuild the catalog on the external enclosure now connected with the old drive. Said that it can not be verified after the execution of the order.

My questionSo, how can I upgrade the operating system, when I can not access the App Store or the Apple App Store account, nor find the recovery partition on what is now the drive external, and that I can not get a CD with the operating system?

Even though I could find the recovery partition, I can not see information on how to use it, except maybe booting the external drive into target disk mode. (which will not work because it will not start)

Short of options … thanks to the good people in advance.

The best thing I can think of is to find a way to copy the recovery partition of the old disk to the new disk (because I can read the old disk), but where is the partition?

I suddenly lost all my Gmail notes on my iMac Pro

I suddenly lost all my Gmail notes on my iMac Pro. By lost, I mean that I open the Apple Notes application and that I do not see any element.

  • I lost them on my iPhone last week and I can not find a good, documented process to solve the problem – so the notes are not synchronized with my iPhone today.
  • I could always see them on my iMac Pro.

I decided to go send them to iCloud Note to stop losing them, [Here is the process I used to “forward them – please describe what you did or better – link to an online article explaining what process you followed]

They are usually found in my email files (mail.app? A screen capture can help us help you here) and also appear in the Notes application.

How to recover my critical Gmail notes?

video – What is the best / fastest way to extract and convert a Blu-ray Disc to an iMac?

I've recently switched (back) from Windows 10 to MacOS running on a 27-inch Retina iMac by the end of 2015. While I was still using my Windows 10 laptop, I used a program called DVDFab to extract my collection of Blu-ray movies in a format suitable for Plex and Emby. The process took about 45 minutes per drive and used the GPU part of the Intel i7 processor in my laptop to speed things up.

Now that I'm on a Mac, I can not find a program (or set of programs) that allows me to extract Blu-ray movies with the same speed or higher speed. Most articles seem to suggest a combination of MakeMKV for extraction and Handbrake for conversion. However, it takes about 45 minutes for extraction and 2 hours for conversion, since none of these programs seem to use GPU acceleration. I have also downloaded some commercial packages to see if they were using acceleration, but I have not yet found any program that can read directly from a Blu-ray disc. ray and perform transcoding to get a mp4 file of suitable size.

Can you recommend a solution other than Windows 10 and DVDFab?

imac – The screen saver Mojave starts randomly

I have a new Mojave installation (10.14.1) on an iMac (Retina 5K, 27 inches, 2017). My screen saver is set to boot after 5 minutes. I have a hot corner set to start the screen saver.

I've noticed that periodically, the screen saver starts all by itself. This usually happens when I scroll through with the magic mouse. I'm definitely not hitting the hot corner.

Any suggestions as to why this happens and how to stop it?

Is it possible to use an imac 2009 as a screen for a macbook pro 2017?

Is it possible to use an imac 2009 as a screen for a macbook pro 2017? If so, what cable will I need for this to work? Ideally, with a mini-port display on a USB-C cable, it would work simply, but I have doubts.

macos – How to remove old epson software from iMac?

My iMac turns slowly and clings. I have reviewed and found that many older EPSON printing software were still running and installed. I found a uninstall executable in the finder:

enter the description of the image here

But when I try to open, I get this error:

enter the description of the image here

I've tried to look at this file via Terminal and I've found that it's actually a directory and the executable execall is here:

MyiMac: / root # / Applications / Epson  Software / Uninstaller.app / Content / MacOS / Uninstaller

and when I run this executable, this window pops up and hangs:

How can this epson bin be removed from my system?

xcode – Is there a way to upgrade a mid-2007 iMac to macOS Sierra?

I have recently used this iMac and hoped to be able to use it for development work. I had an old Mac OS X Snow Leopard installation disc, which I upgraded up to OS X El Capitan, without being able to go further than that.

At the time, I thought it was fine; after all El Capitan is not this old, no?

But apparently I was wrong. I was working with Xcode recently and everything was fine until I started trying to install and use CocoaPods.

Nowadays, most pods have been updated to work with Xcode 9 and (to some extent) are not backward compatible with Xcode 8.2.1 (the farthest I was able to get).

So, currently, I see two ways to solve the problem (other than buying a new Mac, which I have no money to do).

  1. I could find a way to install macOS Sierra (preferred).

    I have reviewed the Sierra Patcher MacOS program, but this computer is not supported.

  2. I could find a way to upgrade to a newer version of Xcode (9 or later)

    This solves the current problem, but not the others I've encountered.
