I’ve tried to get into hardware diagnostics mode using ‘D’ but that doesn’t work I’m not sure why it only picks up the Transcend drive… When I've tried restore from time machine backup with the old hard drive in, no backups are detected. The only USB drive it detects is a Transcend external USB which was used for time machine backups but as I can’t get into recovery mode with the new SSD I can’t restore it. In fact, it doesn’t detect any external drive I've used with TransMac or a DVD with El Capitan on. When I use the ‘Option’ key at boot to select a boot device it only detects the blank SSD, it doesn’t detect the USB.

Then I used TransMac with an El Capitan image, restored the image to a USB drive in an attempt to boot into recovery mode and install using the new image onto the new SSD, which fails to work.įirstly, it won’t boot into recovery mode, I’m guessing it’s because there is no recovery mode available as it was on the old HDD and this older Mac has no internet recovery option. I have replaced the hard drive with the SSD which at first wasn’t detected until I formatted it. I’ve also gone in through safe mode to run the various verify and fsck-fy commands which are failing – so I think it’s a bad diskĬarried out PRAM & SMC Resets which have made no difference I suspect the current disk is failing, I can boot it into recovery mode but have only been able to run first aid on the disk once which failed. Ive tried all sorts of things to repair it, as well as replacing the Hard drive with a Crucial MX500 SSD but nothing is working properly. I have a MacBook Pro Mid 2009, it’s no longer booting properly from the existing hard drive and just gets stuck at the loading screen and eventually reboots in a loop.
