Hi, I tried to upgrade my Mac Book Pro OS 10.6.8 to Yosemite via the App Store. Halfway through the download there was a power failure which interrupted the download and now some of the programs (like Mail) wont work anymore. Also, when I try to initiate a new download of Yosemite the download wont start. Is there something like "System Restore" on Windows to allow me to go back to where I was prior to the upgrade attempt? I would really appreciate advice on this....
Got a tip for us?

Hi,
do you have the install DVD ?
If yes, boot up from it (hold C, or Alt, on boot), go to Utilities/Disk Utility, select your internal drive and repair it.
Also repair the permissions.
Then restart and see how it works.
If you do not have the install DVD, do you have a backup, for example a clone ?
If yes, boot up from it and use its Disk Utility to repair the internal disk.
As for Yosemite download, you might need to delete the partial download (see in the Applications folder : "OS X Installer..." or something like that).

Thanks very much Bruno!! I do have a recent clone backup. Would you mind running through the steps on how to boot from it and how to use its Disk Utility to repair the Disk? Would appreciate it very much.
Connect your external drive to the Mac.
Restart and hold down the Alt key on chime.
On the startup screen, select your clone by using the arrow keys, hit Enter.
The Mac will boot from your clone (this is much slower than booting from the internal disk).
Go to Applications/Utilities, launch Disk Utility.
Select your internal drive in the left side of the window and click "Repair the disk".
Then repair the permissions.
Finally, restart.

Regarding the partial download of Yosemite. I can't get any sign of it on my system. Any ideas on where to look for it? Would "Repair the disk" solve the partial download issue?
Thanks again!
The Yosemite download should be in your Macintosh HD/Applications folder.
Search for "OS X Install....", or "Yosemite....", or "Install OS X....".
The name changes when the download is completed, that is why I no longer remember the exact name during the download.
Also you might need to go to the "Purchases" tab in the App Store to be able to download again.
(try both from the front page and from the Purchases tab).
Repairing the disk won't solve the partial download issue.

I can't find any sign of "OS X Install" files anywhere to enable me to delete the partly downloaded OS. If I go to the App Store and click on OS X Yosemite download the OS X icon moves down to the taskbar and says "downloading" but nothing happens further with no indication that there is progress with the download....
Any ideas??

I just tried to download Yosemite : the actual name (while downloading) is : OS X Yosemite

If for whatever reason you can't download Yosemite, try from the clone...
Boot up from your clone, download Yosemite, then use the Installer (Applications folder) to create a USB installer, or copy it to your internal disk, then reboot from your internal to install Yosemite.
I would NOT recommend to install Yosemite over Snow Leopard, but this is not your question in this thread.
I would rather do a clean install of Yosemite.
This because the gap between 10.6.8 and 10.10.3 is huge.
