Take a look at the OS X Activity Monitor (it's in Applications/Utilities) Do you see a process called installer? Go to /Library/LaunchAgents/ Do you see file names like? com.genieo.completer.update.plist or /Library/LaunchAgents/com.genieo.engine.plist /Library/LaunchAgents/com.genieoinnovation.macextension.plist /Library/LaunchDaemons/com....

I'm posting the solution that worked for me in case of anyone else that has this problem comes across this. I changed the path of the grub EFI executable from /efi/debian/grubx64.efi to /efi/boot/bootx64.efi. Now it is appearing as a boot device in the boot selector, but it still wasn't booting by default. So to make grub boot by default I ran the following ...

Try disabling System Integrity Projection. From what I've seen rEFInd doesn't play as well with El Capitan as it has with older versions. Follow the steps here: http://mattjanik.ca/blog/2015/10/01/refind-on-el-capitan/

You have not begun to given enough information to correctly diagnose your problem. This answer this therefore is based on many assumptions. I know Windows 10 can be installed using the EFI boot method on the newer Mac computers. I do not know if this includes your model. Although, if your Mac does support booting Windows via EFI, then, I believe you should ...

Alright, I see you've added some requisites to your answer. Here goes. Part 1: Install Ubuntu 16.04 Server. Download this. (Ubuntu Server 16.04 32-bit) This is done the same way any other Linux install is done. You will insert the CD/DVD, run through the setup to take the entire partition of the Mac Mini, and once you reach a desktop, you're ready for ...

MBP early 2011 model w/ SSD, Mavericks OS. Allowing shutdown due to out of battery power, I had this twice, with different fixes: SSD was trashed, un-recoverable. Replaced SSD, restored my backup. Back to normal. I fixed it myself; re: iFixit.com repair manifesto Booting from backup would not complete startup (or appeared not to). Cause: Bad video card. ...

Ok, after spending the afternoon looking how to solve this, I found that the easy way was to create a new partition from Windows' side in exFat format. And since the format exFat is modifiable on Mac, unlike NTFS, I can then erase it and then change the format to whichever I want.

Have you recently changed anything in the hardware? I had this happen once trying to swap drives between two Macbook Pros. They were different hardware versions (a couple of years apart), and the laptop from the older Macbook did exactly this when trying to boot in the newer Macbook - the old version of the O/S didn't understand the newer hardware, and ...

After trying to use freely available tools for so long, I gave up and purchased DiskWarrior. Fixed the thread-count issue on the first pass. It's a shame that this wasn't easily possible with non-commercial tools, but DiskWarrior does it's job extraordinarily well.

If you find no option to select your external USB drive as an ISO target - are instead directed to install on your repartitioned hard drive immediately - open the info.plist and add your model identifier to the following: <key>ExternalInstallOnlyModels</key> <array> <string>MacBook8,1</string> <string>MacBook9,1&...

The problem was the internal SATA cable. After exchanging it - this is quite an easy operation, there are plenty of videos on Youtube that describe exactly how it's done - the drive booted flawlessly and is running at a negotiated link speed of 6 Gigabit. To make sure an SSD will work with a Macbook, the Link Speed of the SATA controller should be checked ...

If you are entirely sure that the computer is starting up with a connection to a monitor, then this is a problem with the disk format more than likely. This will make it so that the Mac will not be able to boot into recovery either. You'll need to go to an Apple retailer to ask them to reformat the disk for you, or perhaps it's possible on your own. I know ...

Had the same problem. Found the SSD connector not made as thick as HDD connector this causes contact problem. Quick fix is to cut two thin pieces of printer paper to use as shims to wedge the contacts together. Make them long enough so you can hold them in place as you insert the cable with the SSD.
