It seems as if Disk Utility can't lock the device. This is usually because some other process has open handles on a mount point that resides on the drive. As it's an USB pen drive, I guess you already tried plugging and reinserting it. Thing is: As soon as it gets mounted, something immediately seems to request a lock. This MIGHT be Finder. If you want to ...

Based on the answers you've given in the comments. The device doesn't show in Disk Utility It doesn't show in System Information under USB It works in other computers Other USB sticks work in this computer – Changing USB ports makes no difference The device is getting warm – It also doesn't work in another OS X system I would suggest that there is an ...

According to this article (sorry, german only) the iPhone - attached to a wall charger - detects that no data sync is possible and charges with the full specified power (±1000 mA). Attached to an USB 2 interface (like your Mac) the power is reduced to ±500 mA to not interfere with the data stream. Now the smart PCBs in USB cables as "SONICable" and ...

I found a solution. When you connect to your car using USB it sends the music files to your car stereo and the car system processing them. It's not like AUX connection when the sound just goes to your stereo and plays through the speakers. If you changed the options for individual tracks in your iTunes library, the car stereo receives the files with ...

Here are the steps I use to install Windows without needing to burn to a DVD or flash drive. Keep in mind that the final product will NOT be a virtual machine: Install VirtualBox from http://download.virtualbox.org/virtualbox/4.3.28/VirtualBox-4.3.28-100309-OSX.dmg. Make sure it installs the command line tools. Once installed, open it and create a new VM ...

Not without jail breaking the iPhone. There are numerous tweaks available on Cydia (jail break equivalent of App Store) that enable this functionality. iPhones and a Mac computer will both send SMS messages natively from your phone number, but this isn't available on Windows.

You have to format the SSD without using it as your primary disk. If you're able to run Mac with the old disk, connect the SSD via external enclosure and format it (or make a clone of the running HDD). After this swap the disks, boot form installer and install OS on SSD.

This seems not to be possible. I solved the situation now with the help of my dell external displyay. The USB-Hub there can be configured to shut down as soon as the display ist switched off. So the second display and the active speakers are connected to the power plug that can be switched off/on by USB power. This will allow with the klick of one button to ...

I think the real question is covered by Apple in that no energy is wasted when you have a data connection. The standard charge is: USB 3 - 900 mA at 5V (4.5 Watts) USB 2 - 500 mA at 5V (2.5 Watts) USB 1 - 500 mA at 5V (2.5 Watts) Apple and some third party devices have a high power USB mode: 1100 mA at 5V (5.5 Watts) Apple products will request more ...

A bootable drive saves the entire OS X installer locally. If your current reinstall were happening from a bootable drive, the "downloading Yosemite" step would be nonexistent because everything's already there. As in, you're wrong. The specific benefit of a bootable drive is the ability to reinstall OS X without needing to download it on the spot. (Of ...
