I've created bootable DVDs (DVD+R DL, specifically) for Mavericks, Yosemite, and El Capitan, and used them without any problems to install on various MacBook Pros. Thus, the OS X installer can't require write access to the installer's volume (as of 10.11.x anyway). Creating an El Capitan installation DVD is slightly different than previous, but a user ...

Author of the question answering: It's not necessarily a disk failure since I installed my SSD into a friend's Macbook Pro (same model: retina 15" late 2013, 2.3Ghz) and it works properly. I also tried to insert his SSD into my Macbook Pro and it is not recognized. I don't know where it comes from though...

Apple uses their own boot loader, which only boots OS X, so I am not entirely sure what you mean by secure boot. However, I assume you are asking how you can tell if a Mac has been secured with a firmware password. To find out, simply try to boot the Mac into anything but the normal OS X boot process. Try using an external boot volume, recovery mode, ...

Had EXACTLY the same problem with my Early 2011 Macbook Pro. Kept trying to startup when on external power and made it to about halfway of the progress bar, then stopped and started again. Did nothing when on battery only. For me it was the battery. Before all this happened a full charge would take me only half an hour so I knew it was bad already. Take out ...

When you re-installed the OS, did you erase or repartition the hard drive? The Apple hardware test never found a hardware problem I had with my MacPro so it is not necessarily comprehensive. The Verbose message sounds like a "can't read the hard drive at block...." message. Which would mean a damaged hard drive. There appears to be some part of the OS ...

What I did was format my disk, Then it popped up with the questioned folder I was confused, and after hours of rebooting and holding alt/options and command R/P I just went to where it said install OS X again. Verified it with Apple again. (Press continue). And now I'm playin The waiting game for my computer to restart and hopefully get back to normal ...

From the results you posted, I can see the GUID for the Recovery partition is wrong. This is partition number 3 in the tables. The correct value in the GPT would be 426F6F74-0000-11AA-AA11-00306543ECAC. The fdisk command also shows the value to be wrong in the MBR table. Here, the correct value should be AB. If you can not boot to your Recovery partition ...

It should work, depending on the model of MacBook Air an external USB drive will be able to boot the system but it will likely be slower than an internal drive on the PCI/SATA bus. You should also have a Thunderbolt or mini display port for connecting a monitor. So it should work. Whether or not it will perform acceptably is difficult to say.

Citing http://launchd.info: ~/Library/LaunchAgents and /Library/LaunchAgents are used for the currently logged in user. /Library/LaunchDaemons is for running things as root ( or the user specified with the UserName key) when the machine boots. The key (no pun intended), however, is that plists placed in /Library/LaunchDaemons/ must be owned by root:wheel ...

As this question was asked and last answered a long time ago - things have (slightly) changed today. There is indeed a (limited) multi-user support today for iPads in the educational market. Multiple managed AppleID accounts can be used on a single device and thus it can be shared among several people. There is more information regarding this here: ...

After failing to install the OS using multiple USB drives and slots, I was lucky enough to find an old OSX installation disk in the IT department at work and was able to install the OS.

I'm having the same problem on my MacPro(3,1) Early 2008, except my progress bar gets to about 55%. In verbose mode, it shows it's hanging at a DSMOS / Bluetooth error indefinitely. I suspect I may need to instead create a bootable Mountain Lion, or even Leopard image on my USB. I just dropped $1k on new memory and an SSD PCI Mercury Accelsior, so I'm not ...

Your Mac Pro (MacPro4,1) officially neither supports Windows 10 nor booting from USB thumb drives. The only Mac Pro model supporting Windows 10 installed with Boot Camp Assistant according to Apple is the Mac Pro (Late 2013).

This is no doubt an issue with either your loaded kexts, logic board, or GPU. There isn't any other reason at boot-up for it to crash. I just had my logic board, batttery, trackpad, screen, and keyboard replaced and I'm still having kernel crashes. OSX El Capitan is by far the worst Macintosh OS I've experienced. As someone above said, try clearing the ...

I know this question is old but it is still valid. I was never able to write a Mac installer image to my Flash Drive and have it bootable, unless I did it on a Mac. Using Michael D. M. Dryden's Link, I was able to use the Diskpart command to clean and prep a GPT partition on a flash drive for an OSX Mavericks install image. I used TransMac on Windows 7 to ...

If you're able to boot to the installation drive (external USB, DVD, etc.) but not able to boot from an internal drive, that indicates a hardware problem, likely with the drive or the cable attached to it. An easy test is to attach your internal hard drive externally with something like this. If it boots fine externally, you can be fairly certain that ...

A working approach to get Fedora Xfce Live booting is the dd-method: Download Fedora 23 Xfce Desktop. Attach the thumb drive. The thumb drive will be erased! Open Terminal and enter diskutil list to get the disk identifier of the thumb drive (e.g. /dev/disk3). Unmount the thumb drive with diskutil umountDisk /dev/disk3 Enter: sudo dd ...

Open bootcamp and re-format/install Windows This then worked ...

Since you are talking data recovery now, until you get all your data back DO NOT WRITE TO THE DRIVE YOU ARE RECOVERING UNDER ANY CIRCUMSTANCES, EVER, OR YOU WILL LOSE ANY AND ALL DATA ON THE DRIVE WITH ABSOLUTELY ZERO CHANCE OF RECOVERY!!! If you really want to play it safe you should send your drive to a data recovery service. Those are expensive but you ...
