Trying to run Reallymine on OSX

Hello all,

I'm here with the same problem many others have encountered, my WD My Book failed; not the drive, but the enclosure. The power supply died.

Currently Reallymine is running on an old Lenovo laptop decrypting and imaging a copy of the drive which is great, everything is working fine. But, at the rate it's going, it'll be roughly 60+ days before it's done with the image. It's a 2tb drive that's been running since Sunday 1/28/2018 and has only gotten to 158.8gb copied (out of 2000), about 20gb per day. The computer is old and slow, it's mainly for web browsing and such so I'm not using my working computer for dumb stuff.

I have a 2011 Mac Book Pro that's pretty much loaded. I'd like to try decrypting the drive on that machine, hoping it will drastically cut the amount of time it will take.

I stumbled my way through reallymine in Linux (I'm brand new to Linux). Trying to use the terminal in OSX I'm finding a bit more difficult. I'm no where near being a computer wizard, just a photographer trying to save 5 years of work (the drive died as I was backing it up to a RAID array).

Please don't reply if you're going to ridicule my lack of knowledge on the subject, I never had to use command lines, terminal or Linux before (I find it a bit intimidating to be honest). This only needs to be done one time, I have no other encrypted drives.

Thank you in advance for any and all help. It will be greatly appreciated. If there's anything I can do to return the favor, let me know and I'll do my best.

Regards,
Eric
