I would like to boot from USB3 if possible.
I am getting another 3 TB drive to mirror my 3 TB fusion drive so that I have a bootable copy of my current setup so if something goes wrong I can plug in and go. it can’t boot since the OS was installed on the mini and not from the iMac. Visuals are powered by a dedicated AMD Radeon Pro 560 graphics card with 4GB of vRAM, and for storage, there is a 512GB SSD. On the new mac there is no firewire so I had to hook it up with USB 2.Ģ. The iMac's processor has been upgraded and now houses a 7th-gen Kaby Lake 3.4 GHz Intel Core i5 Quad-Core processor that can be overclocked up to 3.5 GHz, as well as 8GB of 2400 MHz DDR4 RAM. Unfortunately, even though it seems to be available in target disk mode, the system won’t boot.
MAC OPERATING SYSTEM DISC INSTALL
I did a nice clean install and didn’t bother to import my old settings, preferences, software.īut there are things I would like to do with my old lion drive. Recently, I got a new iMac with 3TB fusion drive. It was much faster than the 5400 speed 2.5″ internal drive in the mac mini. My old mac booted from a 1TB Newertech MiniStack via Firewire 800. Your Mac will go back to booting to it’s primary startup disk next time you reboot.
It won’t work for USB and FireWire drives, though.īooting to another volume using either of these methods is a one-time temporary change, so you don’t have to worry about altering any settings to reverse it. This will bypass the selection menu and immediately start from the disc. Rather than hold the Option key, you could instead just press & hold the C key if you’re booting from a CD or DVD disc. This is especially true of USB flash drives. The computer will start up from the chosen volume, but bear in mind performance will likely be much slower than when you normally operate your Mac. Use the keyboard arrows to choose your boot device, then press the Enter key. Continuing to hold this button down will bring up a menu where you can select a disc or drive to boot from. There easiest way to boot to any device other than a Mac’s internal hard drive is to press and hold the Option key immediately after hearing the Mac startup chime. These are all potential reasons for booting to an external device, among many others. Perhaps you’ve got a cloned backup of your entire Mac on an external hard drive and you want to make sure it’s bootable. Or maybe you’re trying to boot from a USB flash drive that has a clean install of OS X on it for troubleshooting purposes.
MAC OPERATING SYSTEM DISC MAC OS X
Let’s say you need to use the Mac OS X installation disc that came with your computer to reformat the hard drive and put it back to factory settings. Apple made it easy so all you need to know is just a simple keyboard command. At some point, you may find a need to boot your Mac from a disc or a drive other than the primary Mac OS X startup volume.
