Mac doesn't recognize mobi

[sadonna]

Recently had to replace the hard drive in my iMac due to smart errors and was never able to upgrade IOS. So now I have Yosemite (Lion - Yosemite skipped Mavericks) and ibooks won't recognize mobi files on my external drive. Is it a issue with ibooks or maybe missing drivers to allow the two devices to communicate.

Welcome to the forums!

What do you mean "won't recognize?" .mobi files are Kindle format, not Apple iBooks format. You can convert them with Calibre (search for it).

OR you can just download the Kindle app for the Mac, which will recognize the files. It's free.
