That error means it failed to connect to the network. Is your network perchance WPA or WPA2/WPA mixed with a password? Apparently Internet Recovery doesn't play well with those (another link). Did that new hard drive have OS X installed or not? If not, it wouldn't be able to boot for obvious reasons. Just to make sure. Have you tried creating a bootable ...

Apple recommends using an USB optical SuperDrive to install Windows when the internal optical drive in unavailable. Even though Apple documentation states a late 2009 iMac does not support Windows 10, this may not be true. I installed Windows 10 on my mid 2007 iMac. In fact, this post was entered using Windows 10 on this Mac. Generally, you should install ...

In order to utilize 16 GB you need, 2 x 8.0GB PC8500 DDR3 (1066 MHz 204 Pin) running Mac OS X 10.7.5 Lion or later and the latest EFI Boot ROM version Firmware for the model Mac you have, which should be ...

For everyone out there having this specific problem. I found that the Apple's Hardware Test didn't show anything wrong. So I stumbled upon a problem with MacBook's Pro from 2015 (15" and 17" only). I called Apple Care and they confirmed this. Finally The iShop (Mexico) Support Service changed the Logic Board for free (the faulty video card is embedded to ...

Turns out this is symptomatic of a SATA cable issue. Seems like writing to the drive was fine (hence installing wasn't an issue), but reading from the drive was causing the issue. Verify and Repair disk in the installer weren't picking up the issue. Replacing the SATA cable fixed the problem.

System Preferences > Displays : Uncheck Automatically adjust brightness ..that's what fixed it for me :)

You could do Command+Option+R to boot into internet recovery (from Apple servers). Ensure a stable internet connection. You can then run csrutil disable in the terminal. As far as your recovery partition. If it is truly not working, you can delete the partition, download the latest OS X installer from the App Store and then reinstall OS X (this will not ...

It's possible to encrypt the entire system volume with FileVault 2 -- open System Preferences -> Security & Privacy pane -> FileVault tab, and click Turn On FileVault. I'll walk you through some setup questions (most important: set up an emergency recovery option, either by linking to your iCloud account or by generating a random key you should write ...

I finally can boot to Bootcamp EFI partition with the help of this answer. In order to boot to Bootcamp EFI partition, you have to bless the EFI partition of the disk that you install Bootcamp, too. So it goes something like this: bless -device /dev/disk0s1 -mount /Volumes/BOOTCAMP -setBoot -nextonly.

You have the option to use the MacBook in "docking mode" (I don't know wether there is an official name for this), which works under these conditions: an external Display is connected the lid of the MacBook is closed the power supply is connected for usability's sake: have additional mouse & keyboard connected Now when you disconnect the power ...

No. It's just not designed to do this: it doesn't have the necessary hardware for lights-out management nor built in features.

This definitely sounds like hardware issue, based on the fact that the HDD worked on a similar Macbook Pro. Before we rule it as hardware, lets perform an Apple Hardware Test . Apple Hardware Test (AHT) contains a suite of diagnostics that will test the hardware of your computer. It's a great way to rule out a hardware issue when troubleshooting your ...

I am currently the owner of a Mac Pro 1,1 dual booting OS X 10.11 (El Capitan) + Windows 10 x64. I didn't experience any driver incompatibility issue. There are few modifications you have to do in order to achieve that goal. Install rEFInd Get an Apple compatible GPU that can be flashed with an "Apple ROM" in order to run the latest OS X version + having ...

Chasing Ghosts You have successfully removed all windows partitions from your disk, but you have not yet removed all files added during your attempt to install windows. What is left are files in your EFI partition. The ghost is being caused by the file efi/boot/bootx64.efi stored in the EFI partition. Open a Terminal window and enter the following ...

Neither of the suggested proposals is advisable. If you erase and reinstall Windows all the music will be lost. Creating a second bootable disk is a complex and error-prone task. If the Windows volume really still exists you can access it in read-only mode and save your music to the OS X volume by default. If you also need write access install an ...

There is no tool or way to do this by yourself. Theoretically, you could run Android on iOS but it would be near impossible. To do this, someone would have to reverse engineer Android and figure out how to dual boot an iOS device. It has been done in the past with the iPhone 2g and the iDroid project so it is possible but it has not been continued. If you ...

It depends on the system installed on the SSD. If the Mac Pro is capable of booting with it and it fits physically, then I see no problem why it shouldn't work. MacPro1,1 - 2,1: max system version: 10.7.5 MacPro3,1 - 6,1: max system version: latest all MacBookPros 2008 (4,1 and 5,1) can run the latest system Usually all necessary drivers for any Mac ...

FileVault must be on. This is why you must enter your credentials after single-user mode is requested.

Sounds like your installation is messed up. Are you able to boot in Recovery Mode? Hold both the Command and R keys on the keyboard until you hear the chime noise.

Turns out it was the battery. I was having the dreaded kernel_task problem where the CPU was using between 300 and 1,200 percent. I assume this was what was causing the mentioned error (among other problems). After disconnecting the battery, the laptop booted fine and I was able to transfer my data.

So it's two months later and I'm a little bit wiser and would like to summarise what I've already posted in the comments and expand on that little. What my colleague forgot to tell me was that the computer had been freezing from time to time even when running Mavericks; he only mentioned freezing after upgrading to El Capitan, which led me to believe that ...

Have you had a luck with it yet? Sound like it may be similar to mine. Logic board for Mac Book Pro's sold between late 2011, whole 2012 and start 2013 are under Apple's Extended Warranty Program. Your symptoms are the same as what I had before mine completely died. Going in tomorrow to have my logic board replaced for free. Thanks Apple. Please see the ...

As it turns out, the adapter was faulty, as it appears. I had not tested it because shortly after the problem occurred, the battery refused to charge so I had to have it serviced.

Could be a hardware related issue (either the MBP or external display) Similar issue happened to me and it turned out to be an issue with the LVDS cable. Also used to work at the Genius Bar, and would see this a lot with certain models of MBP. Try running a hardware test https://support.apple.com/en-us/HT201257 , or if you can take it in to the Genius Bar. ...

Oh, drat! Sorry to say you most likely lost it all. This is the exact reason NO one should just follow any random video on the Web. To explain what I am saying, there is a high probability you used diskutil improperly with the wrong disk identifier (your Startup Disk rather than the intended target) and as root, which most likely overwrote Mac OS X with ...

You may be suffering from a known graphics card issue. The good news, if you are, is that Apple will cover it via a repair extension program: Apple has determined that a small percentage of MacBook Pro systems may exhibit distorted video, no video, or unexpected system restarts. These MacBook Pro systems were sold between February 2011 and December 2013. ...
