This loads the recovery mode from the internet, which will be very slow. The advantage is that there is no stress on the faulty disk. Method A — If you want to save individual files : Go to the menu bar and select Terminal. Press Save and wait. Method C - if you have another Mac : Connect the two computers, e. On your broken iMac, press T at the boot screen to enter target disk mode. Now you can use the Finder to browse the broken disk and copy files. Thank you so much for these suggestions. Unfortunately I don't have an external drive large enough to backup the 2TB desktop; previously I was just banking up select files via Time Machine onto my 1TB external.
One quick question: what kinds of cords will work to connect two computers, as you've outlined in Method C? The desktop is far older than my laptop, and it doesn't have any Thunderbolt sockets. I guess your only option may be a firewire cable. Scott Scott 1 1 silver badge 7 7 bronze badges.

No, that was not the answer to my question. But thanks, anyways… I figured it out. Hi Kendra, do you set a password for your external hard drive? Mine needs the password to unlock the drive which I am not sure how. I am trying to backup my Mac using this process for the past 1 week. I have kept it for hours assuming that the back up would take a long time but it never gets past that screen. Is this an issue or just it taking a long time?

Mine is doing the same. It says to select your external drive, but it does not show that happening in the picture, which confused me at first until I started from the beginning and followed the words rather than the pictures. Hope that helps! So far, so good! Otherwise, I have lost a year since my last back up.
